Dryer Master DM510
Installation Manual
Motor Speed Control Interface Wiring Instructions (for DC drives)
Note: Dryers with discharge systems powered by DC motors may have speed controls where the
speed signals and potentiometer signals are live to power. These systems make use of the Dryer
Moisture Systems Inc. Motor Speed Control Interface to isolate the speed control signals.
If the Dryer Master Motor Speed Control Interface is used, it should be mounted near the motor
speed control for the dryer. The dimensions of the interface are 3" x 5". it is usually mounted inside
the dryer's control panel. Make sure that the installation is in a dry, weather-tight area.
DC Motor Speed Control Interface
Local/Remote Control
The Local/Remote Control allows the DM510 Control Panel to initiate switching of the motor speed
control between local speed pot and the DM510 Control Panel. Below is a list of the multi-cable
requirements for a DM510 system with ALL options.

The DM510 Speed Sense must be set to 0-5 VDC or 0-10 VDC depending what is being sent from the
Dryers speed control. Most frequency drives output 0-10 volts as a speed signal. Changing the
range is accomplished by placing the jumper on J26. Shorting pins 1 and 2 selects a 0-5 volt range
while shorting pins 2 and 3 selects a 0-10 volt range. The default is 0-10 volt range.
The Local/Remote output must be set for 24 VDC, NO output. Placing the jumpers on J5 and J6 does
this. Shorting pins 1 and 2 of J5 will give the 24 VDC while shorting pins 2 and 3 of J6 gives the NO
condition.
