"START-UP FAILURE"
When the pump is running, the power consumed by the pump is permanently monitored.
At pump start-up and after a set follow-up time (see menu 1.2.2.1), if the power consumed by the pump is
below the threshold set (see menu 5.4.5.0), the LED (Fig. 2, pos. 2) turns on.
"PUMP IN DEMAND"
As soon as the pump is operating and the matching pressure switch does not close after a defined period (see
menu 1.2.2.2), the signal lamp (Fig. 2, pos. 3) lights up red.
"SYSTEM MALFUNCTION"
The yellow signal lamp (Fig. 2, pos. 4) signals a software malfunction if the communication between the
control board and the display board is disrupted and the software routine can no longer take place.
"TANK EMPTY"
If the water tank level is too low, the LED (Fig. 2, pos. 5) turns on red.
"START-UP TANK LEVEL MALFUNCTION"
The signal lamp (Fig. 2, pos. 6) turns on red as soon as the level of the pump start-up tank falls below 2/3 and
when the float switch is triggered. If at least one key switch is in the "Auto" position, the pump starts
automatically. If the level rises sufficiently, the signal lamp (Fig. 2, pos. 6) turns off again. The pump must be
switched off manually.
"LEVEL MINI GLYCOL TANK"
If the glycol tank level is too low, the LED (Fig. 2, pos. 7) turns on red.
If the malfunction occurs when the pump is in operation the pump continues to function.
You can acknowledge the error message and the indicator light (Fig. 2, pos. 7) when the level of the glycol tank
is once again above the low level.
"MALFUNCTION"
A signal lamp (Fig. 2, pos. 14) turns on red:
- upon activation of the pump protection device,
- if the thermistor of the motor is triggered,
- if the fuse switch amplifier is open,
- if the fuses have been triggered,
- if a phase sequence malfunction occurs,
- or if a malfunction is detected at the control voltage.
"AUTO MODE"
The signal lamp (Fig. 2, pos. 15/16) is turned on green if the matching key switch is in the "Auto" position. In the
automatic mode, the automatic start-up of the pump is possible either via the intermediary of the float switch or
the corresponding pressure switch.
"NON-AUTO MODE"
The signal lamp (Fig. 2, pos. 17/18) is turned on red if the matching key switch is in the "0" or "Manual"
position. In the non-automatic mode, no automatic start-up of the pump is possible via the intermediary of the
float switch or the corresponding pressure switch.
