Application Examples
The following application and wiring examples are intended to show how the
440G-MZ safety switch products can be applied. If you are the user or the
designer, you may require variations to these examples to meet your specific
requirements.
Wire to GLP Safety 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 12
, the GLP safety relay allows the gate to be unlocked when the motor is
running at a Safely-limited Speed.
