Relay

No line voltage
Normal operation without fault
No enable = OFF
Terminals "D1" - "24 V" (Digital In 1) not
bridged.
Temperature management active
The device has an active temperature
management to protect it from damage
due to too high inside temperatures. In
case of a temperature rise above the
fixed limits, the modulation is reduced
linearly. To prevent the complete system
being switched off externally (in this op-
eration permissible for the controller) in
case of reduced operation due to too
high an internal temperature, no fault
message is sent via the relay.
line failure
The device is provided with a built-in
phase-monitoring function for the mains
supply. In the event of a mains interrup-
tion (failure of a fuse or mains phase) the
unit switches off after a delay (approx.
15 s).
Only functioning with an adequate load
for the controller.
IGBT Fault
Earth fault or short-circuit at inverter out-
put.

Diagnostics / Faults
Reaction of device
Adjustment
In the event of a mains interruption the
unit switches "OFF" and automatically
"ON" when the voltage has been re-
stored.
Check line voltage and pre-fusing.
Switch off by external contact (
ble, device ON / OFF).
With a drop in temperature the modula-
tion rises again llinear.
Check cooling of the controller.
Following a shutoff, a startup attempt is
made after approximately 5 seconds, if
the voltage supply is high enough. This
keeps occurring until all 3 supply phases
are available again.
Check line voltage.
The device switches off, renewed at-
tempt to start after about 60 s
Final switch off when error is detected
after the third start attempt at an interval
< 60 s.
Reset by enable or line voltage ON/OFF.
