8.3.5 Disconnecting control input voltage (ON) and ground E (ꞱE) to safety relay - two channel connection
In applications for which the emergency stop is a normal operation status such as two-hand applications or
safety doors, the control current circuit is switched instead of the control voltage. If possible, use this circuit
example in order to achieve the maximum lifespan.
Switching off the control voltage supply with a controlled motor always results in wear to the electronic
compact starter.
The safety relay and the electronic compact starter can be connected to the same supply. It is not necessary
to connect to two different supplies.
Please use two channel connection to prevent from cross-circuit failure.
