180 OVERLOAD
The motor current has overcome
the limit fixed by hardware.
"If the alarm condition occurs
again, ask for assistance to a EP
technician.
The fault condition could be affected
by wrong adjustments of motor
parameters."
181 WRONG ENC SET
Mismatch between parameters
ENCODER PULSES 1 and
ENCODER PULSES 2
"Set the two parameters with the
same value, according to the
adopted
encoder"
185 TILLER ERROR - -
186 WAIT MOT.P STILL
If DC Pump option is set to ON,
the software expects the voltage
on -P output to be at a “steady
state” value, before switching the
LC on. If the voltage is different,
it could be due to the fact that the
motor connected to -P is not still.
For this reason, the software waits
30 seconds for the voltage to be
at the “steady state” value (and for
the pump motor to be still). After
this time, the software assumes
that the problem is not due to the
fact that the pump motor is not still,
and show the PUMP VMN NOT OK
alarm.
"1- If the motor connected to -P is
still moving, just wait for it to be still.
2- If not, in 30 seconds the alarm
PUMP VMN NOT OK will appear."
187
"LIFT+LOWER
MANY PUMP
REQ."
if there's more than one pump
function request,e.g. lift+tilt,the
alarm occrus
"1-check the microswitches status
2-check the wiring of pump
functions
3-disconnect the wire on the
controller side
4-If the problem is not solved,
replace the logic board."
