MODEL CUB®5T - MINIATURE ELECTRONIC PRESET TIMER
AND CYCLE COUNTER
GENERAL DESCRIPTION
The CUB5T provides the ultimate in timer flexibility, from its complete user
programming to the optional relay output and serial communications capability.
The meter functions as an Elapsed Timer or Preset Timer. It also has a built-in
Cycle Counter. The display can be toggled either manually or automatically
between the Timer and Cycle Counter values. With eight different input
operating modes and 18 selectable timer ranges, the meter can be programmed
for a wide variety of timing applications.
The CUB5T has an LCD display with 0.46" (11.7 mm) high digits. The LCD
is available in two versions, reflective (CUB5TR00) and backlight (CUB5TB00).
The backlight version is user selectable for red or green backlighting with
variable display intensity.
The Timer has two signal inputs and eight input operating modes. These
modes provide level active or edge triggered start/stop operation. A Display
Hold mode will display the elapsed time for one cycle, while the next cycle
continues timing internally. The Timer Reset modes will automatically reset the
timer value when a time start edge is applied to the input. This allows sequential
timing cycles without having to manually reset the Timer.
In addition to the Timer inputs, a programmable User Input is available to
perform a variety of meter functions. All inputs are current sinking (active low)
and accept a variety of logic and open-collector output signal sources. Relay and
switch contacts can also be used as signal sources, when the software input
debounce filter is enabled.
The capability of the CUB5T can be easily expanded with the addition of a
field installable option module. When the CUB5RLY0 relay output module is
added, the meter becomes a Preset Timer. The Setpoint Output can be assigned
to the Timer or Cycle Counter values, and configured to suit a variety of control
and alarm requirements. Serial communications capability for RS232 or RS485
is added with a serial option module (CUB5COM).
The CUB5T can be powered from an optional Red Lion Micro-Line/Sensor
Power Supply (MLPS), which attaches directly to the back of a CUB5T. The
MLPS is powered from an 85 to 250 VAC source and provides up to 400 mA to
drive the meter and sensors.

INSTALLATION
The meter meets NEMA 4X/IP65 requirements when properly installed. The
unit is intended to be mounted into an enclosed panel. Prepare the panel cutout
to the dimensions shown. Remove the panel latch from the unit. Slide the panel
gasket over the rear of the unit to the back of the bezel. The unit should be
installed fully assembled. Insert the unit into the panel cutout.
While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel latch
should be engaged in the farthest forward slot possible. To achieve a proper seal,
tighten the latch screws evenly until the unit is snug in the panel (Torque to
approx. 28 to 36 in-oz [0.202 to 0.26 N-m]). Do not over-tighten the screws.
INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the operating
temperature and provides good air circulation. Placing the unit near devices that
generate excessive heat should be avoided.
The bezel should only be cleaned with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate the
aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the
keypad of the unit.

WIRING OVERVIEW
Electrical connections are made via screw-clamp terminals located on the
back of the meter. All conductors should conform to the meter’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.
Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed
(stranded wires should be tinned with solder.) Insert the lead under the correct
screw-clamp terminal and tighten until the wire is secure. (Pull wire to verify
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm).
EMC INSTALLATION GUIDELINES
Although Red Lion Controls Products are designed with a high degree of
immunity to Electromagnetic Interference (EMI), proper installation and wiring
methods must be followed to ensure compatibility in each application. The type
of the electrical noise, source or coupling method into a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.
1. A unit should be mounted in a metal enclosure, which is properly connected
to protective earth.
2. Use shielded cables for all Signal and Control inputs. The shield connection
should be made as short as possible. The connection point for the shield
depends somewhat upon the application. Listed below are the recommended
methods of connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end where the
unit is mounted.
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors, feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run through metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter. Also, Signal or Control cables within
an enclosure should be routed as far away as possible from contactors,
control relays, transformers, and other noisy components.
4. Long cable runs are more susceptible to EMI pickup than short cable runs.
5. In extremely high EMI environments, the use of external EMI suppression
devices such as Ferrite Suppression Cores for signal and control cables is
effective. The following EMI suppression devices (or equivalent) are
recommended:
Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:
Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)
6. To protect relay contacts that control inductive loads and to minimize radiated
and conducted noise (EMI), some type of contact protection network is
normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide
varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.
b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor
switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid
state outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.
RLC part numbers: Snubber: SNUB0000
Varistor: ILS11500 or ILS23000
7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could affect the instrument’s operation.
Visit RLC’s web site at http://www.redlion.net/emi for more information on
EMI guidelines, Safety and CE issues as they relate to Red Lion Controls
products.

The Plug-in cards are separately purchased option cards that perform specific
functions. The cards plug into the main circuit board of the meter after the rear
cover is removed
WARNING: Disconnect all power to the meter before
installing Plug-in Card.
REMOVE/REPLACE THE REAR COVER
To remove the rear cover, locate the cover locking tab below the 2nd and 3rd
input terminals. To release the tab, insert a small, flat blade screwdriver between
the tab and the plastic wall below the terminals. Inserting the screwdriver will
provide enough pressure to release the tab locks. To replace the cover, align the
cover with the input terminals and press down until the cover snaps into place. CAUTION: The Plug-in cards and main circuit board contain static
sensitive components. Before handling the cards, discharge static
charges from your body by touching a grounded bare metal object.
Ideally, handle the cards at a static controlled clean workstation.
Also, only handle the cards by the edges. Dirt, oil or other
contaminants that may contact the cards can adversely affect circuit
operation.

hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential
of the user input common with respect to earth ground; and the common of the plug-in cards with respect to input common.

PROGRAMMING MODE ENTRY (SEL KEY)
It is recommended all programming changes be made off line, or before
installation. The meter normally operates in the Display Mode. No parameters
can be programmed in this mode. The Programming Mode is entered by
pressing and holding the SEL key. If it is not accessible, then it is locked by
either a security code, or a hardware lock (See Module 3).
MODULE ENTRY (SEL & RST KEYS)
The Programming Menu is organized into separate modules. These modules
group together parameters that are related in function. The display will alternate
between  and the present module. The RST key is used to select the desired
module. The displayed module is entered by pressing the SEL key.
MODULE MENU (SEL KEY)
Each module has a separate module menu (which is shown at the start of each
module discussion). The SEL key is pressed to advance to a particular parameter
to be changed, without changing the programming of preceding parameters.
After completing a module, the display will return to  . Programming
may continue by accessing additional modules.
SELECTION / VALUE ENTRY
For each parameter, the display alternates between the present parameter and
the selections/value for that parameter. The RST key is used to move through the
selections/values for that parameter. Pressing the SEL key, stores and activates the
displayed selection/value. This also advances the meter to the next parameter.
For numeric values, press the RST key to access the value. The right hand
most digit will begin to flash. Pressing the RST key again increments the digit
by one or the user can hold the RST key and the digit will automatically scroll.
The SEL key will advance to the next digit. Pressing and holding the SEL key
will enter the value and move to the next parameter.
PROGRAMMING MODE EXIT (SEL KEY)
The Programming Mode is exited by pressing the SEL key with  
displayed. This will commit any stored parameter changes to memory and
return the meter to the Display Mode. (If power loss occurs before returning to
the Display Mode, verify recent parameter changes.)
PROGRAMMING TIPS
It is recommended to start with Module 1 and proceed through each module
in sequence. When programming is complete, it is recommended to record the
parameter programming and lock out parameter programming with the user
input or programming security code.
FACTORY SETTINGS
Factory Settings may be completely restored in Module 3. This is useful
when encountering programming problems.
Pressing the RST key on power-up will load the factory settings and display
rESEt. This allows operation in the event of a memory failure or corrupted data.
ALTERNATING SELECTION DISPLAY
In the explanation of the modules, the following dual display with arrows will
appear. This is used to illustrate the display alternating between the parameter
on top and the parameter’s Factory Setting on the bottom. In most cases,
selections and values for the parameter will be listed on the right.

This parameter determines how the Timer Input Signals affect the Run/Stop
status of the Timer. Timing diagrams are shown below for level active and edge
triggered (1-input or 2-input) operation. For single input modes (Input A only),
Input B provides a level active Timer Inhibit function. In the Display Hold
mode, the timer display value remains held and only updates when a Timer
Start (Input A) or Timer Stop (Input B) edge occurs.
The timer reset (rSt) operating modes are identical to the other modes in the
diagrams, except the timer display value is reset at the Time Start edges.
The Timer can also be stopped at a Timer Stop Value or at Setpoint output
activation or deactivation. This type of Stop condition is cleared when a Timer
Reset occurs, or another start edge is applied on the timer input.
For Reset Modes (rSt), the timer is reset at Time Start edge.

entered in the same display format as the Timer Range selected. Non-zero
values are normally used for “timing down” applications, but they can also
provide an offset value when timing up.

Automatic Reset). The Input B (INPUt b) selection generates a count each time
Input B is activated. This selection overrides the timer inhibit function of Input
B, when the timer is programmed for Level or Edge-1 operating mode (See
Module 1 for Timer Input Operating Modes).
The User Input (USr1NP) selection generates a count each time the User Input
is activated. When selected as the count source, the User Input can still be set
to perform a User Function described in Module 1. In this case, the Cycle

BAUD RATE
Set the baud rate to match that of other serial communications equipment.
Normally, the baud rate is set to the highest value that all of the serial
communications equipment is capable of transmitting and receiving.
Select either 7- or 8-bit data word length. Set the word length to match the
other serial communications equipment on the serial link.
This parameter only appears when the Data Bit parameter is set to a 7-bit
data word length. Set the parity bit to match that of the other serial equipment
on the serial link. The meter ignores parity when receiving data and sets the
parity bit for outgoing data. If parity is set to NO, an additional stop bit is used
to force the frame size to 10 bits.
Enter the serial node address. With a single unit, an address is not needed
and a value of zero can be used (RS232 applications). Otherwise, with multiple
bussed units, a unique address number must be assigned to each meter. The
node address applies specifically to RS485 applications.
This parameter determines the formatting of data transmitted from the meter
in response to a Transmit Value command or a Block Print Request. Select NO
for a full print transmission, consisting of the meter address, mnemonics, and
parameter data. Select YES for abbreviated print transmissions, consisting of the
parameter data only. This setting is applied to all the parameters selected in the
PRINT OPTIONS. (Note: If the meter address is 0, the address will not be sent
during a full transmission.)

This parameter selects the meter values transmitted in response to a Print
Request. A print request is also referred to as a block print because more than
one parameter can be sent to a printer or computer as a block.
Selecting YES displays a sublist for choosing the meter parameters to appear
in the print block. All active parameters entered as YES in the sublist will be
transmitted during a block print. Parameters entered as NO will not be sent.
The “Print All” (Prnt ALL) option selects all meter values for transmitting
(YES), without having to individually select each parameter in the sublist.
Note: Inactive parameters will not be sent regardless of the print option
setting. For example, the Cycle Counter and Cycle Counter Start values will
only be sent when the Cycle Counter is enabled. If disabled, these parameters
are inactive and will not be transmitted. Likewise, the Setpoint parameters will
not be sent unless an optional setpoint card is installed in the meter.

Command String Construction
The command string must be constructed in a specific sequence. The meter
does not respond with an error message to illegal commands. The following
procedure details construction of a command string:
1. The first 2 or 3 characters consist of the Node Address Specifier (N) followed
by a 1 or 2 character node address number. The node address number of the
meter is programmable. If the node address is 0, this command and the node
address itself may be omitted. This is the only command that may be used in
conjunction with other commands.
2. After the optional address specifier, the next character is the command
character.
3. The next character is the register ID. This identifies the register that the
command affects. The P command does not require a register ID character. It
prints all the active selections chosen in the Print Options menu parameter.
4. If constructing a value change command (writing data), the numeric data is
sent next.
5. All command strings must be terminated with the string termination
characters * or $. The meter does not begin processing the command string
until this character is received. See timing diagram figure for differences in
meter response time when using the * and $ terminating characters.
Command String Examples:
1. Node address = 17, Write 350 to the Setpoint On value
String: N17VF350$
2. Node address = 5, Read Timer value, response time of 50 msec min
String: N5TA*
3. Node address = 0, Reset Setpoint output
String: RF*
4. Node address = 31, Request a Block Print Output, response time of 2 msec min
String: N31P$
Transmitting Data to the Meter
Numeric data sent to the meter must be limited to Transmit Details listed in the
Register Identification Chart. Leading zeros are ignored. The meter ignores any
decimal point and conforms the number to the appropriate display format. (For
example: The Timer range is set for tenths of a second and 25 is written to the
Timer Start register. The value of the register is now 2.5 seconds. In this case,
write a value of 250 to equal 25.0 seconds).
Note: Since the meter does not issue a reply to value change commands, follow
with a transmit value command for readback verification.
12
Sending Serial Commands and Data
When sending commands to the meter, a string containing at least one
command character must be constructed. A command string consists of a
command character, a value identifier, numerical data (if writing data to the
meter) followed by a command terminator character, * or $.

Receiving Data From The Meter
Data is transmitted from the meter in response to either a transmit command
(T), a block print request command (P) or a User Input print request. The
response from the meter is either a full field transmission or an abbreviated
transmission, depending on the selection chosen in Module 5.
Full Field Transmission
* These characters only appear in the last line of a block print.
The first two characters transmitted are the meter address. If the address
assigned is 0, two spaces are substituted. A space follows the meter address field.
The next three characters are the register mnemonic, as shown in the Register
Identification Chart.
The numeric data is transmitted next. The numeric field (bytes 7 to 18) is 12
characters long. When a display overflow exists for a requested timer or cycle
counter value, an * (used as an overflow character) replaces a space in byte 7.
Byte 8 is always a space.
The remaining ten positions of this field consist of seven positions for the
requested value with decimal points positioned for the selected timer range. The
data within bytes 9 to 18 is right-aligned with leading spaces for any unfilled
positions.
The end of the response string is terminated with a and . After the
last line of a block print, an extra , and are added to provide
separation between the print blocks.
Abbreviated Transmission
* These characters only appear in the last line of a block print.
The abbreviated response suppresses the node address and register mnemonic,
leaving only the numeric part of the response.
Meter Response Examples:
1. Node address = 17, full field response, Cycle Counter = 875
17 CNT 875
2. Node address = 0, full field response, Setpoint On value = 250.5

Command Response Time
The meter can only receive data or transmit data at any one time (half-duplex
operation). During RS232 transmissions, the meter ignores commands while
transmitting data, but instead uses RXD as a busy signal. When sending
commands and data to the meter, a delay must be imposed before sending
another command. This allows enough time for the meter to process the
command and prepare for the next command.
At the start of the time interval t1, the computer program prints or writes the
string to the com port, thus initiating a transmission. During t1, the command
characters are under transmission and at the end of this period, the command
terminating character (* or $) is received by the meter. The time duration of t1
is dependent on the number of characters and baud rate of the channel.
t1 = (10 times the # of characters) / baud rate
At the start of time interval t2, the meter starts the interpretation of the
command and when complete, performs the command function. This time
interval t2 varies. If no response from the meter is expected, the meter is ready
to accept another command.
If the meter is to reply with data, the time interval t2 is controlled by the use
of the command terminating character. The ‘*’ terminating character results in
a response time of 50 msec. minimum. This allows sufficient time for the
release of the sending driver on the RS485 bus. Terminating the command line
with ‘$’ results in a response time (t2) of 2 msec. minimum. The faster response
time of this terminating character requires that sending drivers release within 2
msec. after the terminating character is received.
At the beginning of time interval t3, the meter responds with the first
character of the reply. As with t1, the time duration of t3 is dependent on the
number of characters and baud rate of the channel. At the end of t3, the meter is
ready to receive the next command.
t3 = (10 times the # of characters) / baud rate
The maximum serial throughput of the meter is limited to the sum of the
times t1, t2 and t3.

Communication Format
Data is transferred from the meter through a serial communication channel.
In serial communications, the voltage is switched between a high and low level
at a predetermined rate (baud rate) using ASCII encoding. The receiving device
reads the voltage levels at the same intervals and then translates the switched
levels back to a character. The voltage level conventions depend on the interface
standard. The table lists the voltage levels for each standard.
Data is transmitted one byte at a time with a variable idle period between
characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit,
an optional parity bit and one or more ending stop bits. The data format and
baud rate must match that of other equipment in order for communication to
take place. The figures list the data formats employed by the meter.
Start Bit and Data Bits
Data transmission always begins with the start bit. The start bit signals the
receiving device to prepare for reception of data. One bit period later, the least
significant bit of the ASCII encoded character is transmitted, followed by the
remaining data bits. The receiving device then reads each bit position as they are
transmitted.
Parity Bit
After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission
(including the parity bit) is either even or odd. This bit is used by the receiver
to detect errors that may occur to an odd number of bits in the transmission.
However, a single parity bit cannot detect errors that may occur to an even
number of bits. Given this limitation, the parity bit is often ignored by the
receiving device. The CUB5T meter ignores the parity bit of incoming data and
sets the parity bit to odd, even or none (mark parity) for outgoing data.
Stop Bit
The last character transmitted is the stop bit. The stop bit provides a single bit
period pause to allow the receiver to prepare to re-synchronize to the start of a
new transmission (start bit of next byte). The receiver then continuously looks
for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2
stop bits are sent from the meter.
