Fault Signalling Relay K1 - AEG Thyro-A Operating Instructions Manual

If the power controller is supplied from an external 24V source at the
extra electronics supply input (see page 62, Connecting additional
electronics supply), the device sends a frequency error message but
does not switch off.

3.8.2 Fault signalling relay K1

(only for ...H RL1 and ...H RLP1)
Fault signalling relay K1 has a changeover contact. Messages that
cause the fault signalling relay to switch can be set with THYRO-
TOOL FAMILY. In the default state, fault signalling relay K1 functions
on the closed circuit principle.
In the event of the following errors, the fault signalling relay de-ener-
gizes and the power controller switches off:
• SYNC error
• internal error
• undervoltage in the mains
• master/Slave error
• error rotating field / phase
In the event of the following errors, the fault signalling relay de-energizes,
the power controller remains on and a message is sent (LED):
• excess temperature
• undercurrent in the load circuit
NOTE
Default setting
The function explained here is described in the default
state.
This setting can be changed with a bus module or with
THYRO-TOOL FAMILY.
