1..11 = Please refer to legend 7.3.4.
When parameter 74 is set to 5 or 6, the power feed to the external
(NON EN16005) sensors must be switched via this contact. This will allow the
controller to switch the sensors on and off during a test cycle.
When the controller is set in accordance to the EN16005:
Relay 3 will be automatically configured as a monitoring relay for safety
devices. No other setting is possible.
Parameter 75 : (0) Relay 3 configuration (N.O. or N.C.)
