Recommendations about the connections
7.4.1
Connection of the pilot contacts at the interlock output
On the socket side (device side), two shortened contacts are installed as pilot contacts to generate a signal. The interruption of this
connection signals the device to shut down before the main contacts are pulled out. In this way, the emergence of DC arcs is avoided
when pulling out the plug under load (see also chapter 4.3).
If the pilot contacts in the connector half are bridged on the device side, the device cannot detect if the connection cable on the load
side is unplugged or interrupted. In this case, protection against DC arcs is not possible. The pickup output is also not de-energized
(locking) when the connection line to the load is interrupted. This can lead to unsafe operating conditions.
In order to get the full benefit of the pilot contact function, we recommend always making the bridge circuit on the load side. This
ensures that the device goes into a safe state, no matter at which point the connection between the load and the device is interrupted.
Please note the examples given below.
