Step Five
CHANGING FROM 120 TO 240 VAC:
1. Remove the two screws from the top of the printed circuit board
(PCB) and gently slide the PCB from the housing. Use caution
when removing the PCB.
2. Located jumpers JWA, JWB and JWC on the PCB.
3. To change to 240 VAC, remove jumpers from JWB and JWC
and place a single jumper across JWA. To change to 120
VAC, remove jumper JWA and place jumpers across JWB and
JWC.
4. Gently return PCB into housing and replace the two screws.

RELAY LATCH LOGIC TABLE:
With Latch ON, the relay will actuate when INPUT 1Aand INPUT 1B are in the same condition. The relay will
not change its condition until both inputs reverse their state.

The example shown below has the Invert Off and the Latch ON. With Invert ON, follow the above left chart.
Note: Some sensors (particularly buoyancy sensors) may have their own inverting capability (wired NO or
NC). This will change the logic of the invert switch. Check your system design.
With Latch OFF, the relay will
actuate only from INPUT 1A and
INPUT 1B will be ignored.
