Package Contents
A complete SCMC TM control system contains the following items:
1) SCMC TM control unit;
2) Power cable (MK-1003);
3) PWM Hydraulic control cable (SF-1005);
4) Valve hydraulic control cable (MK-2005);
5) Trigger cable (JP-1002);
6) This manual;
If any of these items are missing, please contact your distributor for replacement parts.
Functional Overview
SCMC TM is a manually regulated plow controller which adjusts the “contact weight” (down
force) that the moldboard of a snowplow exerts on a road surface. The system decreases or
increases the contact weight of the snowplow depending on the position of the Set Point.
This controller is able to transfer weight from the truck to the plow to increase the
plowing capability for packed snow/ice. (This feature requires a snowplow designed for
down pressure and the proper size truck).
Normal Operation:
1. Turn the power switch on.
2. To activate the system turn the engage switch to “ON” or set the Trigger.
3. Turn the Set Point dial to reduce or increase the contact weight.

Features
Power Switch
The Power Switch is the master power switch for the SCMC TM. The SCMC TM requires
13 Volts to operate. When the power switch is enabled the white text on the control
panel is backlit with red LED’s to act as a visual indicator that the SCMC TM is powered
on.
Set Point
The set point dial varies the “PWM port” output voltage between 0 and 13 volts. The
available output voltage is defined by the set point on the dial. The higher the set point
the greater the output voltage signal. For example:
Set point dial set to 0  output will be “off” 0 volts
Set point dial setting 1-9  output will be linear; between .1 ~12 volts
Set point dial set to 10  output will be fully “on” ~13 volts
Note: the above output references are based on a calibration setup of minimum trim
= 1 and maximum trim = 10. Output voltages will vary based upon min and max
calibration settings.
Engage Switch/Trigger
The engage switch and trigger allow the set point dial to become active to turn on the
“PWM port” and the “Valve power port.” The PWM output and valve power can be
activated when the engage switch OR the trigger are active. The trigger becomes active
when it is supplied with 13 volts. The following table defines the states of the engage
switch, trigger and output:
Engage
Switch
(On/Off)
Trigger Input
(12V/0V)
Output
Enabled
Off 0V False
Off 12V True
On 0V True
On 12V True
Red LED
The red LED signals that the PWM port and Valve ports are turned “on”.
Power
A jumper is set to allow 12 or 24 Volts to be supplied to the SCMC TM.

Valve Power
This is a static 12V output, which supplies 12 volts to the valve when the PWM port is
turned on.
PWM Output Signal
The PWM output produces a linear output PWM signal to a hydraulic coil which is
dependent on the Trigger, Engage, Min/Max calibration, and the Set Point dial. The
output is labeled ‘PWM’ on the back of the control panel and should be connected to the
valve with the SF-1005 cable. The full range of the Set Point dial (0-10) is used to vary
the signal.
Calibration
The SCMC TM stores the minimum voltage, maximum voltage and frequency response for
various types of hydraulic setups. All 3 of these values are field configurable to provide
optimum user performance. To modify and/or change these values follow the below
process:
1.)Turn the engage switch “off” (Red part of the switch is NOT showing)
2.)Turn the power “off” on the SCMC TM
3.) Rotate the set point dial to number 10
4.) Turn the power switch “on”
a.) Within 1 seconds turn on the “ENGAGE” switch (red bar of switch showing)
b.) Within in 1 seconds rotate the set point dial to “0”
5.) The red LED on the front of the controller should now be blinking slowly
(approximately 10 times per second). If it’s not, start over at step 1.
6.) Turn the set point dial to 10 if you are using a 24 volt system, and to 0 for a 12 volt
system.
7.) Click the engage switch to the “off” position (non-red bar) and then back to the “on”
position. This saves the 24/12 volt supply voltage value.
8.) Choose the preferred frequency of the coil that the controller is attached to. Rotate the
set point dial to the desired number based on the table below. Default is set to 200 hz.
Set Point
Dial Value
<1 2 3 4 5 6 7 8 9 10
PWM
Output
Frequency
40 60 80 100 120 150 175 200 250 300

Table 1 Set Point PWM Frequency Calibration
9.) Click the engage switch to the “off” position (non-red bar) and then back to the “on”
position. This saves the frequency value.
The red LED should now be blinking slower (around 3 times per second).
10.) The controller is now in minimum voltage calibration:
a. Turn the set point dial to the minimum value that allows for the blade to just
start to lift off of the ground. Or where the blade just starts to reduce pressure off
of the ground. Default is #1.
b. Click the engage switch to the “off” position (non-red bar) and then back to the
“on” position. This saves the minimum trim value.
The red LED should now be blinking faster (approximately 10 times per second).
11.) The controller is now in maximum voltage calibration:
a. Turn the set point dial to the maximum value that allows for the blade to lift off
of the ground. Or where the blades movement is to your preference. Default is
#10.
b. Click the engage switch to the “off” position (non-red bar) and then back to the
“on” position. This saves the maximum trim value.
12.) Turn the engage switch to the “off” position.
13.) Calibration is now complete. Turn the engage switch “on”. Move the set point
knob to the desired setting.
*Note: If the red LED is still blinking, this signifies that the minimum output voltage set point was greater than the maximum set
point during calibration, the process needs to be restarted at step 1.
