TROUBLESHOOTING

To supplement the troubleshooting guide in the alarm list, below there is also a guide to identify other possible problems.
We assume that the control panel has been connected correctly to the power supply line, that the
electric pumps have been connected correctly to the control panel as described in the manual, and that
all connection cables are in working condition.
PROBLEM
If a latching alarm occurs, carry out
the following procedure to reset it
If the control panel is in the ON state, i.e the pumps are enabled in any operating mode, and
the thermal cut-out built into the motor opens the NO voltage-free contact more than five
times, the control panel enters the latching "MOT. PR. ERR" alarm state. This alarm must be
reset manually.
In this state, the pumps are stopped and at the same time the EXT ALARM relay is activated to
generate an external acoustic and visual alarm.
If the control panel is in the ON state, i.e the pumps are enabled in FILLING MODE 4 only, and
the float on IN1 and IN2 open the NO voltage-free contact to indicate that there is no water in
the accumulation tank, the control panel enters the "NO WATER" alarm state.
In this state, the pumps are stopped and at the same time the EXT ALARM relay is activated to
generate an external acoustic and visual alarm.
At power-up, the three-phase control panel checks for all three phases. If one of the three
phases is missing, the control panel enters the "PHASE MISS" alarm state and disables all of
its functions.
At power-up, the three-phase control panel checks that the phases cycle in the correct se-
quence. If the connection was made in the wrong sequence, the control panel enters the
"PHASE ERROR" alarm state and disables all of its functions.
SOLUTION
• Press the key
• The alphanumeric part of the display will ask for which of the two electric
pumps in an error state you want to reset the alarm (if there are two electric
pumps and both are in an error state).
Displayed message:
PUMP1
CLEAR ERROR?
• Press the
• If the second electric pump is also in an error state, the following message will
appear on the display:
PUMP2
CLEAR ERROR?
• Press the
key to permanently reset the alarm.
