28 "PUMP VMN
LOW"
X X X X Alarm: wrong voltage
output of pump chopper;
the motor voltage feedback
is not coherent with
applied PWM
-If the alarm is present in Init
status,remove the alarm
cause
-If the alarm has occurred in
stby or running mode, it is
necessary to remove the fault
cause and to activate a
function request
56 "PUMP STBY I
HIGH"
X X X Alarm: in stby condition
(no PWM applied to pump
chopper), the pump
current sensor feedback is
out of the zero current
window
-If the alarm is present in Init
status,remove the alarm
cause
-If the alarm has occurred in
stby or running mode, it is
necessary to remove the fault
cause and to activate a
