Multifunctional Access Box and Guard Locking with Time Delay Safety Relay
Four status indicators on the access box provide visual information about
system status:.
Status/Diagnostic Indicators
Additional Features
Auxiliary/Manual Release
The auxiliary release lets you manually unlock the guard door in the event of
unforeseen or uncommon circumstances.
Note:
When release monitoring is active (default factory setting), the system enters into a
latching fault when the manual release is actuated. If the manual release is actuated too
slowly, the system will not enter into a latching fault.
To reset the access box, turn the power off for at least three seconds or apply
24V to the input RST for a minimum of three seconds. (In this demo, use the
reset button next to the circuit breaker to the power supply.)
Note:
You can reconfigure the access box DIP switches to deactivate Release
Monitoring (refer to Chapter 4 – Change Device Configuration (use of DIP
switches) in 442G-UM001A-EN-P).
