WARNING
This instrument contains electronic components that are susceptible to damage by static electricity. Proper handling*
procedures must be observed during the removal, installation or handling of internal circuit boards or devices.
*Handling Procedure
1. Power to unit must be removed.
2. Personnel must be grounded, via wrist strap or other safe, suitable means, before any printed circuit board or other
internal device is installed, removed or adjusted.
3. Printed circuit boards must be transported in a conductive bag or other conductive container. Boards must not be
removed from the protective enclosure until the immediate time of installation. Removed boards must be placed immedi-
ately in a protective container for transport, storage or return to factory.
Comments:
This instrument is not unique in its content of EDS (electrostatic discharge) sensitive components. Most modern electronic
designs contain components that utilize metal oxide technology (NMOS, CMOS, etc.). Experience has proven that even
small amounts of static electricity can damage or destroy these devices. Damaged components, even though they appear
to function properly, exhibit early failure.

DESCRIPTION:
The Minitrol-S is a single input totalizer/ratemeter. The totalizer
and ratemeter each have their own 5 digit dividing scale factor.
The two 5 AMP preset relay outputs can be programmed by the
user to apply to the “A” total counter or the “A” ratemeter. The user
can view the rate, total and grand total. The B relay can be used to
create a scaled pulse output. Magnetic pickup input, analog output
and RS232 communication options are available.

NOTE: The remote reset does not reset the grand total.
K FACTOR/SCALING
The K-Factors are used to convert the input pulses to engineering
units. The 5 digit K-Factor dividers, with decimal keyed into any
position, allow easy direct entry of any K-Factor from 0.0001 to
99999. Separate factors may be entered for rate and total.
CONTROL OUTPUTS:
Relays:
2 each N.O. Relay; 5 Amps120/240 VAC or 28 VDC.
(N.C. relay contacts and NPN transistor output
available with solder jumpers. Transistor output is
internally pulled up to 10 VDC through relay coil, sinks
from 10 VDC to .5 V @ 100 mA)
Analog Output:
An optional 4-20mA (0-20mA) output is available for
the Minitrol series. The output can be programmed
to track rate or total. This feature is available by
adding suffix A to the part number. Connections are
via a 2 terminal pluggable screw connector.
Programming is accomplished by using the front panel
in conjunction with rear dip switches.
Accuracy: ±0.25% FS
Compliance Voltage: 3 to 30 VDC non inductive.
RS232/RS422 SERIAL 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.

PRESETS
Two control outputs are provided. To set relay A or B's functional-
ity, press “menu” button until “Relay” appears on the display, the A
and B outputs can be assigned to the rate alarm (high/low), or for
total/grand total. A 5 digit value can be entered for both presets A
and B. 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 corresponding
totalizer will auto reset at the preset. This may be used to create a
relay scaled pulse output.
LOCKOUT
Unauthorized front panel changes can be prevented by entering a
user selected 5 digit code, in the “LOC" mode. The front panel can
be completely locked out or the presets can remain accessible.
RATEMETER
Accurate to 4 1/2 digits (±1 display digit). The rate meter can be
programmed to:
• accept almost any number of pulses per unit of measurement
• sample from 2 to 24 seconds maximum
• auto-range up to 5 digits of significant information.
The display can be programmed to read in units per Second ( sec ),
Minute ( min ), Hour ( hour ), or Day ( day ).
TOTALIZER
The two 6-digit totalizers can count at 10kHz speed. They share a
5-digit dividing scale factor. The totalizer advances on the positive
edge of each pulse.

HOW 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 Engineer-
ing.

WIRING GUIDLINES
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 transient voltage interference. In some environments voltage spikes of over
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.
TOTALIZER INHIBIT INPUT
In many applications it is sometimes necessary to inhibit totalization while certain operations are present. A high logic level
on this input inhibits totalization while the rate indication is still active. This feature is useful during meter proving and may
be used with liquid phase detectors.
4

CONNECTING AC / DC POWER
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.
CONNECTING SENSOR INPUTS
These diagrams show how to hook a typical input sensor 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 FACTORS
There are two separate dividing scale factors, one for rate and one for total. The factors are entered as
the number of pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999.
Because the “units per second”, “minute”, “hour” or “day” are field programmable from the keypad,
scale factor calculations for the ratemeter are easy.
RATE (Factor A)
The Rate K-Factor value should be entered in pulses per unit of measure. Be sure to choose the
desired Time Base (sec, min, hour, day) in the Rate menu section.
Rate = Input Frequency x Time Base
Factor A
Where Time Base:
SEC = 1
MIN = 60
HOUR = 3600
DAY = 86400
TOTAL (Factor B)
The Total K-Factor (Factor B) value should be entered as pulses per least significant digit for display.
The DPLOC (decimal location) under the count section is a "dummy" decimal. Therefore the Total K-
Factor must be scaled properly for totalizer decimal adjustments.
EXAMPLE:
Flowmeter Output: K = 56.27 pulses per gallon
FACTOR B TO READ
56.27 0 GAL
5.627 0.0 GAL
.5627 0.00 GAL
Total = Input Frequency

This section sets up the relay information.
Press the PRGM key to choose A TOT (A
assigned to total) or A RATE (A assigned to
rate). Press enter when the desired choice is
displayed.
This is the duration (.1 to 99.9 sec) that relay
A will remain energized. If 00.0 is selected,
the relay will latch until reset
Press the PRGM key to choose B TOT (B
assigned to total) or B RATE (B assigned to
rate). Press enter when the desired choice is
displayed.
This is the duration (.1 to 99.9 sec) that relay
B will remain energized. If 00.0 is selected,
the relay will latch until reset

OUTPUT WIRING
The following diagrams detail the connection of the relay and analog output options. Each relay consist of a form A contact
(Normally Open). NPN transistor or Normally Closed contacts are available with solder jumpers (see Jumper Options).
ANALOG OUTPUT
The analog output can be selected to output 4-20 mA or 0-20 mA and can be selected to track the rate or total.
Pin 13 supplies 12 to 18V to power the current loop. Pin 14 supplies the current sinking driver. When connecting
a strip chart recorder, make connections as follows:
GND
+12V

ALARMS
The relays can be used to trigger alarms which warn the operator that the total or the rate has
exceeded a setpoint. The outputs are programmable to be assigned for rate or total. When assigned to the
total, the relays can have a user selectable on time (duration) or can be latched until reset. The total autorecycles
when set for a selectable on time. This can be use to create a relay pulse output.
