Switching capacity 230VAC / 4A and 48VDC / 3A
Digital outputs can be configured as desired using the display and operating unit and
remote display software. Parameter groups 1030 to 1099.
Factory setting:
• Relay output 1: Collective fault quiescent current method
• Relay output 2: Warning and maintenance
• Relay output 3: Measurement
• Relay output 4: Limit value 1
• Relay output 5: Limit value 2
• Relay output 6: Limit value 3
• Relay output 7: Limit value 4
Parameters of digital inputs
Idle state
Here, the idle state is set. This state is present when none of the functions triggers a
switching operation. The Diagnostic mode setting allows the idle state to be changed
via the State parameter (see below).
• LOW (normal open contacts)
• HIGH (idle state)
• Diagnostic mode
Parameters:
1030/1040/.../1090
