X21 signaling contact

Table 8- 8
Max. connectable cross-section 1.5 mm
Type: Screw terminal 2 (see Chapter "Control cabinet installation and EMC / connection system")
The 2-pole terminal connector for the signaling contact is included in the Completion Kit provided.
The signaling contact can be wired to a digital input (DI) of the Control Unit to indicate the
failure of a Control Supply Module.
The signaling contact operates as an isolated NO contact. When the switch is closed, the
Control Supply Module is "OK" and provides the output voltage. The switch opens in the
event of a fault "Not OK" – when the overtemperature condition is still present, after a pre-
warning, wire breakage, short-circuit etc. The Control Supply Module is correspondingly
switched off.
