Dryer Master DM510 Installation Manual
Moisture Sensors Wiring Instructions
While wiring the sensors refer to Figure 30 - Sensor hook-up schematic. Both the Inlet and Outlet
Moisture Sensor Multi-Cables should be wired as follows:
The Moisture Sensor End
1. Follow the instructions given in the section “General Wiring Procedure ” to strip the PVC
jacket and expose 4" (10 cm) of wire.
2. Cut off the foil shield and the drain wire at the sensor end of the cable.
3. Tape over the exposed ends of the foil shield and drain wire so that they are insulated from
contact with the metal work and the circuit board.
4. Strip ½" (7mm) and twist (colour to colour) and crimp to the wires exposed in the moisture
sensor using the crimp connectors provided in the sensor.
5. Join the ground wire in the moisture sensor to the ground wire from the DM510 Control
Panel using a wire nut.
The DM510 Control Panel End
1. The Multi-Cables from the Moisture Sensors connect to the DM510 Control Panel
termination. Attach them using the connectors as indicated in Figure 29 - Sensor hook-up
physical
2. Connect the Multi-Cable drain wire and the 18-gauge ground wire from the Moisture Sensors
to the ground wire in the DM510 Control Panel.
Notes:
Sensor Signal specification
Red = 18 to 28 vdc, 20mA
Black = Signal return & dc Gnd.
Green = Moisture signal
White = Temperature signal
Maximum Wire length DM510 to sensor = 300 meters, 1000 feet. Additional lightning protection is
recommended when exceeding 60 meters, 200 feet.
Important
During the following procedures, the drain must be grounded at the DM510 I/O Panel and isolated
from the ground at the field end.
