Application Examples
The following application and wiring examples are intended to show how the
440G-LZ safety switch products can be applied. If you are the user or the
designer, you may require variations to these examples in order to meet their
specific requirements.
Wiring to GLP Relay
The GLP safety relay is designed to operate with Power to Release (PTR)
switches. To use a Power to Lock (PTL) switch, you must use an interposing
relay on the lock command at GLP terminal 51. In the example shown in
Figure 11
, the GLP allows the gate to be unlocked when the motor is running
at a Safely-limited Speed.
