4.4 Terminal assignment relay
When connecting accessory devices to the potential-free relay, make sure that the
max. switching current of 5 amperes is not exceeded.
► Relay status in monitoring mode:
The relay is “picked up” (normally open contact closed / normally closed contact open)
► Relay status in alarm or error mode:
The relay “drops out” (NO contact open / NC contact closed)
Limit data: Re1 (alarm) 250 V ~ / 5 A
Re2 (error) 60 V = / 5 A
