The receiver has limit control terminals, and you can connect external devices (with normally closed contact), such as sensors, limit switches to limit terminals, then use them to stop the motor or the linear actuator.
For example, you can connect a normally closed limit switch to terminals COM and UP, and connect another normally closed limit switch to terminals COM and DOWN.
When motor rotates in positive direction, or linear actuator extends outward, if disconnect two terminals COM and UP, the motor or linear actuator will stop automatically.
When motor rotates in reversal direction, or linear actuator inward retracts, if disconnect two terminals COM and DOW, the motor or linear actuator will stop automatically.
Wired control terminals:
The receiver has wired control terminals, and you can connect external devices (with normally open contact), such as manual switches to wired control terminals, then use them to control the motor or the linear actuator.
For example, you can connect three manual switches to wired control terminals STOP, S1, COM and S2 according to following wiring diagram.
1) In Interlocking mode:
When connect two terminals S1 and COM, the motor rotates in positive direction, or the linear actuator extends outward. And when connect two terminals STOP and COM, motor or linear actuator stops.
When connect two terminals S2 and COM, the motor rotates reversal direction, or the linear actuator inward retracts. And when connect two terminals STOP and COM, motor or linear actuator stops.
2) In Momentary mode:
When connect two terminals S1 and COM, the motor rotates in positive direction, or the linear actuator extends outward. And when disconnect two terminals S1 and COM, motor or linear actuator stops.
When connect two terminals S2 and COM, the motor rotates reversal direction, or the linear actuator inward retracts. And when disconnect two terminals S2 and COM, motor or linear actuator stops.
