Maintenance
The maintenance work must be carried out twice a year.
The device must be switched off. The plug for the safety circuit must be removed.
The device must be switched on. The configuration 0 (no plug inserted) must be
recognized.
If the connector for the configuration is plugged in, a path in the safety circuit must be
opened when the release circuit is closed. The release circuits must open. If the path
is closed again, the release circuits must not close.
The test must be repeated with the other safety circuit.
It must be checked for correct function.
The connected safety elements must be checked for mechanical damage and proper
function and replaced if necessary.

Configuration 3: Protective door / test cage with antivalent contacts
Wiring diagram
The switch position corresponds to the open door.
When switching on the protective door is open or waiting for an open protective
door.
When switching on the switch positions must not be unequal.
There is a simultaneity monitoring with 2.5 s. If the simultaneity is violated, the
enabling circuits are not closed and a correct switching sequence is maintained (ie
simultaneity is maintained).
Initial operation
The desired configuration is displayed by
ETL DataView 3
.
With a closed protective door, the enabling circuits must not close when switching on.
If only one switch is actuated or if simultaneity is violated, the enabling circuits must
not close.
