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:

A jumper is set to allow 12 or 24 Volts to be supplied to the
SCMC
TM
.
