Isolated common
1. Remote setpoint must be isolated and powered from external source
2. PV retransmission requires an external power supply within 12 to 36 VDC .
Maximum load = (Power supply VDC 8 VDC) / .020 A.
3. A switch may be placed between terminals 9 and 10 on TB3 to interrupt actuator
travel. Contact between 9 and 10 will stop actuator movement.
DO NOT POWER.
