DESCRIPTION:DESCRIPTION:
The Minitrol is a dual input (channel A and B) counter/ratemeter,
each with its own 5 digit dividing scale factor. The two 10AMP
preset relay outputs can be programmed by the user to apply to the
"A" total counter, the "A" ratemeter, or the "B" counter or the net
total of A and B inputs. The user can view the Net Total of "A+B",
the Net Total of "A-B", the rate of A, or A and B counters separately. The "MRT" version shows rate and total (as described
above). The "MC2" is exclusively a counter and the "MR2" is
exclusively a ratemeter.

RS232/RS422SERIAL INTERFACERS232/RS422SERIAL INTERFACE
If the serial interface option is supplied, up to 99 units can be linked
together. (The terminal addressing the unit must be capable of
driving all loads in the loop.) Unit status and new set points can be
communicated by serial communication. Mode changes, however,
must always be made on the front panel. Data is transmitted at
selected baud rates using standard seven bit ASCII characters and
parity with two additional bits of Start and Stop to make up the
standard ten bit character.
Data is received and transmitted over standard EIA RS232 or
RS422 levels. Each 10 bit character is made up of a start bit, 7 bit
ASCII code, parity bit and stop bit. Unit number, baud rate and
parity are entered in the Program Setting set up mode and remain
in memory even if power is off.
Note that the input impedance of RS232 is 3K or 7K Ohm worst
case. The terminal addressing the unit must be capable of driving
all loads in the loop. RS422 input impedance is much higher and
there is usually no problem driving 25 units. Unit serial transmit line
remains in a high impedance OFF state until addressed.

Two control outputs are provided. To set relay values, press
menu button until Relay appears on the display, the A and B
outputs can be assigned to the ratemeter (high/low), one preset for
rate and one for total, or two presets (2 stage shut off) on the A and
B counters. A 5 digit value can be entered for both presets and the
decimal point location is the same as the counter. The outputs can
be set to energize from 0.1 to 99.9 seconds or latch (0.0). If a
value other than 0.0 is entered, the counters will auto reset at the
preset . In the A-B or A+B versions, the relays will be assigned to
either net total or A rate.

HOW TO MOUNT THE UNITHOW TO MOUNT THE UNIT
HOW TO MOUNT THE UNIT
HOW TO MOUNT THE UNITHOW TO MOUNT THE UNIT
The unit is designed to be mounted with a gasket providing a water tight seal. Two mounting brackets are provided to
secure the unit to the panel. A panel less than .1" may distort if the clamps are screwed too tightly.
Slide the body of the unit through the rubber gasket. Insert the unit into the panel. As shown in "FIG. A", slide the brackets
up the groove to press against the back of the panel. Insert screws into rear of brackets and tighten them evenly and
alternately. Do not over tighten! A normal level of torque is required. Maximum torque should be 3" pounds.
This product is designed to be panel mounted and is NEMA 4 rated if proper mounting procedures are followed and the
required and supplied hardware is correctly used.
If the panel in which the unit is mounted is less than .125 of an inch thick, the possibility exists that there will be some
flexing. Should this flexing occur, the resulting deformation of the panel could cause a loss of the water tight seal. In case
this should occur, the use of silicone or other sealant would be recommended.
This product is designed to the NEMA 4 rated. However, the fact that we are unable to control either the location in which
the device is installed or the actual installation itself requires that the company’s liability shall extend only to the repair or
replacement of a defective product.
We are prepared to offer additional assistance in those special situations where normal mounting methods do not seem to
satisfy the customers needs. This assistance may be obtained by calling the factory and asking for Application Engineering.

WIRING MINITROLWIRING MINITROL
WIRING MINITROL
WIRING MINITROLWIRING MINITROL
The rear terminal contains 12 screw terminals for connecting #14 to #28 gauge wire.
The unit is controlled by a microprocessor and, therefore, an electrically "noisy" environment could cause operating
problems. The input power line should not be common to power lines for motors, pumps, contactors, etc.
The unit is designed to be immune from line or RF voltage interference. In some environments voltage spikes of over 100
volts, even 1000 volts, can occur. When common to a power line driving motors voltage fluctuations can be extreme and
rapid. Lines driving DC or AC solenoids, relays, or actuators can also cause problems.
Four sources of noise can occur:
1) AC power line noise - If the unit cannot be connected to a clean power source, an inductive load suppressing device
(MOV as GE # V130LA1 or Resistor Capacitor as Paktron # .2 uf/220 ohm @ 400V) can be installed. Although locating
the suppressor across the AC supply at the unit should help, best results are obtained by connecting the suppressor
across the leads of the "load" at the device causing the spike.
2) Input line noise -The noise is carried on the input and D.C. ground lines. Make sure the input wires are never run into
the unit in a bundle with power input lines. Also, keep these input lines isolated from inductive lines from devices
drawing heavy loads. If there is a possibility of electrical noise, we recommend using shielded cable, with the shield
being hooked to the D.C. ground terminal on the instrument, and to "earth" at one point in the circuit, preferably at the
D.C. ground terminal of the unit.
3) Output lines - The unit has two relay outputs. When these outputs are used to run external relays or solenoids, spikes
can be generated upon activation. This noise can spread through the instrument causing operating problems. If the
source is a D.C. operated device, a general purpose diode (IN4004) placed across the solenoid prevents electrical
noise spikes. Connect the cathode (banded side) to the more positive side of the coil. If the source is an A.C. operated
device, use a MOV or Resistor Capacitor across the coil.
4) 12 VDC output supply - Noise can be generated on the 12 VDC output supply if it is used to drive inductive loads or if
the current draw exceeds 50 mA. Insure that all inductive loads have a diode (such as IN4004) across the coil and that
the current does not exceed 50 mA.
UP/DOWN CONTROL AND QUADRATURE INPUTSUP/DOWN CONTROL AND QUADRATURE INPUTS
UP/DOWN CONTROL AND QUADRATURE INPUTS
UP/DOWN CONTROL AND QUADRATURE INPUTSUP/DOWN CONTROL AND QUADRATURE INPUTS
QUADRATURE INPUT:
When programming the counter section for quadrature input, you must set the unit for A net B and A sub B (see step 2 in
programming section). This insures proper operation. The rate can only be viewed in one direction. If the unit is a
ratemeter only (MR2), connect only one of the quadrature channels to Input A (pin 5).
UP/DOWN CONTROL:
When using the up/down control option, Input A (pin 5) is the count input and Input B (pin 6) is the up/down control
(direction) input. The counter must be set for A net B and A sub B (see step 2 in programming section).
When the direction input is high (4-30VDC) the count inputs will count up, when the direction input is low (open or less than
1VDC) the count inputs will count down. The direction input must precede the count input by 1 msec when the unit is set for
low CPS and 1 usec when set for high CPS.

NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has
been designed with an isolated AC input. Thus, polarity is not a concern for the AC input. The chassis is plastic, therefore
earth ground is not used. For D.C. operation, connect + 12V to pin 7 and - D.C. to pin 8.

These diagrams show how to hook typical input sensors to the unit. The unit supplies an unregulated 12 Volt (50mA)
output to power these sensors (Pin 7).
A valid pulse is one which makes a transition from the off-state (0 to 1V) to the on-state (4 to 30V): a positive going edge.
The input impedance is 10K Ohms to ground. The unit can be programmed from the front panel for slow switch closure
inputs up to 40Hz (select "Lo CPS"), or solid state switches (select "hi CPS") up to 9.99KHz. No rear terminal jumpers are
required. Use PNP (sourcing) type pulsers.

CALCULATING SCALE FACTORSCALCULATING SCALE FACTORS
CALCULATING SCALE FACTORS
CALCULATING SCALE FACTORSCALCULATING SCALE FACTORS
There are two separate dividing scale factors, one for input "A" and one for input "B". The factor to enter is the number of
pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999. The factor is the same for rate and
count on input "A". Because the "units per second", "minute", or "hour" are field programmable from the keypad, scale
factor calculations for the ratemeter are easy. Here are some examples:
SCALING FACTOR EXAMPLES:SCALING FACTOR EXAMPLES:

BATCHINGBATCHING
BATCHING: You want to count the number of batches (10 boxes each) being loaded onto a pallet.
BATCHINGBATCHING
Solution Solution
Solution - Dial in a scale factor of 10.
Solution Solution
UNIT COUNTING:UNIT COUNTING:
UNIT COUNTING: You pick up a notch on a paper roll (1 pulse per shaft revolution). Each revolution equals 3 feet. To
UNIT COUNTING:UNIT COUNTING:
find the number of pulses per foot, simply divide "1 pulse" by "3 feet" (1÷ 3 = .3333).
Solution Solution
Solution - One foot equals 0.3333 pulses, enter this as the scale factor and the display will read in feet.
Solution Solution
RATERATE
RATE: The shaft of a motor has a flywheel with 10 spokes. The KEP DO series prox switch is mounted to
RATERATE
sense 10 pulses per revolution. RPM of the shaft is the desired readout.
SolutionSolution
Solution: Enter a Factor of 10 and for every 10 pulses, "1" will appear on the display. Set rate per
SolutionSolution
second, minute or hour as desired.
A conveyor carrying bottles must be controlled for bottle speed. For each revolution of the front roller, three bottles
travel by. Thus, one revolution equals 3 bottles. A wheel with seven spokes is mounted on the roller. The user
can’t sense bottles because they are traveling through a washer, so a sensor is placed at the roller, sensing seven
pulse per revolution of the shaft, which equals 3 bottles per revolution.
To calculate the scale factor (7 ppr ÷ 3 bottles) = 2.3333 scale divider. Set rate per second, minute or hour as
desired.
A flow meter is generating 52.6 pulses per gallon. The desired readout is in liters. Since there are 3.785 liters per
gallon, divide 52.6 by 3.785 to find the number of pulses per liter (52.6 ÷ 3.785 = 13.897).
Enter 13.789 as the scale factor so the display will read in liters.
An aluminum sheeting plant has a cut to length application to customer specification. A ten pulse per revolution
encoder with a 12" wheel is used to sense. The travel of aluminum sheets is in inches. Thus, after 10 pulses, you
want 12 to appear on the display. Thus, 10 ÷ 12 = .8333. Enter .8333 as your scale factor.

If XX is the desired device number press return (enter), if not
enter the desired number after the question mark and press
return (enter).
BAUD RATE:BAUD RATE:
BAUD RATE:
BAUD RATE:BAUD RATE:
The baud rate is the speed at which data is transmitted,
expressed in bits per second. Baud rates of 300, 600, 1200,
2400, 4800 or 9600 are available. When in the baud rate
section of the menu, the unit will list :
BAUD RATES:
1:300 2:600 3:1200
4:2400 5:4800 6:9600
then prompt you:
BAUD RATE <300>?
Press return (enter) if this is the desired baud rate or enter the
assigned number of one of the six possible baud rates. If an
invalid baud rate is entered the unit will prompt you to choose
another baud rate. This will occur until a valid baud rate is
entered or escape is pressed.
PARITY:PARITY:
PARITY:
PARITY:PARITY:
Parity is a bit of information that is inserted before the stop bit
and is used to help check if the transmission is correct. When
setting the parity you may select "ODD" (parity bit is logic 0 if
total number of logic 1’s in the first seven data bits is odd),
(s)= space bar(s)= space bar
(s)= space bar. The
(s)= space bar(s)= space bar
"EVEN" (parity bit is logic 0 if total number of logic 1’s in the first
seven data bits is even), "MARK" (parity bit is always logic 1
- High / Mark) or "SPACE" (parity bit is always logic 0 - Low /
Space). If a "MARK" parity is chosen, it will appear that two
stop bits are used. Use the "MARK" parity with terminals using
parity "OFF" or "NONE". These terminals ignore the parity.
The unit does not check the parity but does transmit the parity
chosen. When setting the parity, the unit will print:
PARITIES:
MARK-0 SPACE-1 EVEN-2 ODD-3
Then the unit will prompt you:
PARITY<MARK>?
If this is the desired parity press return (enter), if it isn’t enter
the number of the desired parity then press return (enter).
STROBE LIST:STROBE LIST:
STROBE LIST:
STROBE LIST:STROBE LIST:
The serial interface card is also equipped with a strobe line.
When the strobe line is triggered, a chosen set of data will be
transmitted to be displayed or printed. The selections for the
display list are entered in the program mode. Enter "1" to add
selections to the list and enter "0" to delete selections from the
list. The seven available items for the strobe display list are:
(1) Preset A, (2) Preset B, (3) K-Factor A, (4) K-Factor B, (5)
Rate of A, (6) Count A, (7) Count B. In the "A net B" mode
Count A will display the Net Count and Count B is an invalid
command and the unit will transmit useless data. When
setting the strobe list the unit will print :
ENTER STROBE LIST:
DO NOT DISPLAY-0 DISPLAY-1
The unit will prompt you:
PRESET A<DISPLAY>?
PRESET B<DISPLAY>?
K-FACTOR A<DISPLAY>?
K-FACTOR B<DISPLAY>?
RATE<DISPLAY>?
COUNT A<DISPLAY>?
COUNT B<DISPLAY>?
If the above choices are entered, when the strobe line is
triggered (3-30V positive pulse) the unit will transmit:
DEVICE# 1:
PA XXXXX
PB XXXXX
KA XXXXX
KB XXXXX
DR XXXXXX
DA XXXXXX
DB XXXXXX
(SEE COMMANDS BELOW FOR DESCRIPTION OF COMMAND CODES).
Each time the strobe line gets triggered the unit will transmit
this data unless the program mode is entered and the strobe
list altered.
After these four items have been entered they will remain
unaltered unless the program mode is entered again and the
values changed. The unit is now set and must be addressed
by it’s device number to come on line again.

SERIAL INPUT COMMANDS:SERIAL INPUT COMMANDS:
SERIAL INPUT COMMANDS:
SERIAL INPUT COMMANDS:SERIAL INPUT COMMANDS:
To get a unit on line you must address it by it’s device number.
This is done by typing DXX(S), XX= device number. The unit
comes on line and echoes back DEVICE# XX. Insure that
"DEVICE# XX:" is received before requests are sent. The unit
is now ready to receive a command or string of commands
separated by a space. A carriage return (enter) will enter the
commands and processing of requests begins. The carriage
return (Hex Code "D") puts the unit "off line" after data is
processed.

SERIAL INTERFACE OPERATION:SERIAL INTERFACE OPERATION:
SERIAL INTERFACE OPERATION:
SERIAL INTERFACE OPERATION:SERIAL INTERFACE OPERATION:
Data is received and transmitted over standard EIA RS232 or
RS422 levels. Each ten bit character is made up of a start bit,
seven bit ASCII code, a parity bit and a stop bit. Device
number, baud rate, parity and strobe list are entered in the
program setup mode and will remain in memory even if power
is lost.
The input impedance of RS232 is 3KΩ to 7KΩ worst case. The
terminal addressing the unit must be capable of driving all
loads in the loop. The input impedance of RS422 is much
higher and there should be no problem driving as many as 99
units. The transmit line remains in a high impedance "off"
state until addressed. Only one unit is to be on line at a time!!!
More than one unit on line could damage the unit or destroy the
transmitted data.
When the unit is active (on line) it will operate in a full duplex,
echo back mode, so that data sent from the terminal will be
transmitted back for verification. When the unit is "on line",
use the proper serial transmit commands to request data or
set a new value. Up to 80 characters of data can be linked
together and transmitted to the unit in a string as long as there
is a space between the commands. If an error is made, a
correction can be made by back spacing and retyping correct
data before the return (enter) is sent. Once a return (enter) is
sent, the unit begins processing the data and will transmit the
requested data on a non-priority basis over the data transmit
line. A keypad entry or incoming data will halt the data
communication cycle. Therefore, there should be a pause
after data is requested to insure that all data has been
transmitted before making another request or addressing
another unit. If the unit is not busy, it should not take longer
than 300 msec to process each request. To find the cycle time
to process and transmit a request, calculate the bit transmit
time by using this formula: [(1÷ baud rate) x (80) + .005] x
number of requests made. This time will be extended if the unit
must service the front keypad. If transmission has not started
within two seconds after data is requested, it can be assumed
that there is a problem. The unit transmits a carriage return
and line feed after each data value. Any new communication
must be started with DXX(S) (device number and space).

When connecting the unit to a printer, you must first program
the desired baud rate, parity and strobe list with a computer.
After the unit is programmed it can be connected to the printer.
Connect the transmit line(s) of the unit to the receive line(s) of
the printer and be sure that both devices have common
grounds. When the strobe line is triggered the unit will transmit
the selected strobe list which you had previously programmed.

POSSIBLE CAUSESPOSSIBLE CAUSES
POSSIBLE CAUSES
POSSIBLE CAUSESPOSSIBLE CAUSES
1. AC or DC power wiring is incorrect.
1. Line noise is affecting the processor
due to a current spike or surge.
1. Input wiring is incorrect.
2. Scale factors are incorrect.
3. Transmitting device is defective.
4. Wrong debounce filtering selected.
5. Minitrol is defective.
1. The unit is trying to display a
number which it can’t (too small or
too large).
2. Line noise affected unit on power
up.
SOLUTIONSSOLUTIONS
SOLUTIONS
SOLUTIONSSOLUTIONS
1. Recheck power wiring
1. Use a different power supply or
install a surge suppressor.
1. Recheck input wiring.
2. Recheck scale factors and factor
calculations.
3. Replace transmitting device.
4. Recheck debounce filtering selection
"hi cps" or "lo cps".
5. To confirm set scale factors at one
and connect a wire to pin #7 and
touch it to pin # 5 (input A). Each
time pin #5 is touched counter A
should count once. If not, call
factory for RMA. (this test will not
work on units with quadrature input)
1. Check scaling factor, if it is correct,
lower the number of significant
figures.
2. Reprogram the unit and be sure to
enter a decimal (enter one and re
move it if a decimal is not desired).
Relays are not activating properly.
Counter resets before reaching 999999.
Various menu items are not being displayed.
1. Wrong relay duration.
2. Relay set for wrong activation
i.e. count instead of rate.
1. Relay duration is set at a value other
than 00.0. This causes the counter
to auto-reset at the preset.
1. The menu flow chart and the setup
steps show the setup for the units
with rate and total (MRT). When
using a unit which has only count
(MC2) or only rate (MR2,) several
menu items will not be displayed.
1. Recheck programmed relay duration.
2. Recheck programmed relay
activation mode.
1. If relay outputs are not being used,
set the relays for rate (MRT only).
2. Set the relay durations to 00.0.
1. The menu items which do not
appear are not used for the models
without the ratemeter (MC2) or
without the counter (MR2).
Therefore, disregard any menu items
which appear on the flowchart and
setup steps, but do not appear on
the unit’s display.
