3-phase current
For monitoring the 3-phase current, the 3 phases must be connected to inputs Ex5, Ex6
and Ex7 in the correct order (L1, L2, and L3). The controller monitors the correct
temporal order of the 3 phases. Any phase asymmetry, phase interruption or too low
rated voltage of one or several phases is regarded as a 3-phase error.
If a 3-phase error is continuously present during the period of time set under "Delay 3-
phase error" (2894), the compressor is switched off for the minimum off time. The
controller delivers status message
180: Current asymmetrical.
If the 3-phase error occurs again within "Duration error repetition" (2889) for at least the
delay time, the heat pump initiates lockout, if the preselected number of errors has
been exceeded. The controller delivers error message
355: Current asymmetrical.
The heat pump must be manually reset.
