Overload protection
Overload protection is activated after completion of the
soft start. In this way, the consumption of current is restric-
ted and the speed is regulated to 5,550 rpm. This means
that the motor will not be damaged, by the hydraulic com-
pression of the circulating pump.
Error mode
The motor is switched off by the error mode in the event
of faults. After approx. 5 seconds, the motor will be swit-
ched from error mode into the power-saving sleep mode.
Sleep mode
In sleep mode, the internal users of the motor’s electronic
system are switched off. The consumption of current in
this mode then amounts to < 2 mA.
Reactivation of the motor
The motor can be reactivated from sleep mode. This is
done by disconnecting it from the power supply for ap-
prox. 2 minutes. After the voltage supply is restored, the
motor will restart in soft start.
Reverse polarity protection
The motor is
not equipped with internal reverse polari-
ty protection
. The wiring harness in conjunction with
a15A fuse protect the motor against reverse polarity.
