Diagram 1
Circuit for key switch to allow Lodar to be “SET”, key can then be removed. Use the key switch to energise the relay, this breaks the “STOP” circuit, the receiver can be “SET” using the transmitter, this in turn powers “S+” which will hold the relay open. The key can now be removed. If the Lodar “STOP” button is used, “S+” and hence the relay will be de-energised, and the key will have to be used to reactivate the Lodar receiver.

The key switch is used to de-activate (break) the “STOP” circuit, the receiver can then be “SET”. Reactivate the “STOP” circuit and remove the key for system security.

Typical uses, over temperature etc., in fact any input whereby the equipment manufacturer decides that continued use will endanger the operator, or damage the equipment. Making the circuit will force a “STOP”. wiring.06

LODAR OUTPUT
If a relay is required to be a Parallel Master then it must be driven by the Master output. If the relay is required as a Continuous Master it can be driven by the Master output or the “S+ S-” connections, this then frees up the Master output, allowing it to be used for another function either Parallel or Continuous. wiring.06
