Byte 15: Fault 1

The fault signals contain the causes why the actuator cannot be operated.
Value Description
1 Incorrect configuration, i.e. the current setting of the actuator controls is invalid.
0 Configuration is ok.
1 Due to insufficient mains quality, the controls cannot detect the phase sequence
(sequence of phase conductors L1, L2 and L3) within the pre-set time frame provided
for monitoring.
0 No signal
1 Motor protection tripped
0 No signal
