Wiring Instructions for WD-1 The WD1 Timer will operate on voltages of 24 to 48 VDC or 24 to 120 VAC. The internal relay contacts are rated at 10 amps with a maximum output voltage of 120 VAC. The WD1 Timer is shipped with a 3K ohm resistor connected between terminals A2 and B1. This resistor must be in place for proper operation. Once setup is complete and everything is wired as shown in the diagram above, set the WD1 time delay knob for desired delay. Example: Set the WD1 timer to 5 using the dial knob. If the WD1 does not receive a pulse from the MS1 within the 5 seconds, the WD1 will de-energize the contacts. The contact configuration on the WD1 are as follows:
Terminal 15 : Common (C)
Terminal 18 : Normally Open (NO)
Terminal 16 : Normally Closed (NC)
