4.0 ALARMS
4.1 MOTOR ALARM
The motor alarm is present in all CD pump models with motors in direct current.
In the event of excessive absorption of the motor due to malfunction, or if the power supply voltage of the pump (30
Volts) drops below 24 Volts, the pump performs three attempts to restart the motor. The three attempts carried out
before the alarm signal are respectively after 5 seconds, then 10 seconds and finally after 15 seconds from the
previous stop. The alarm is signalled as follows:

Acoustic signal through the buzzer (if installed on the pump), with a frequency of 1 second on and 1 second
off;

flashing red LED;
 “
not
” flashing on the display;
In this alarm status the motor is stationary. Restoring normal status to the equipment is carried out by turning
off/turning on the switch or through the power supply.
4.2 MAINTENANCE ALARM
The maintenance alarm is activated when the pump has been running for longer than the time set in the relative
O.F.d sub-menu (see Settings Menu).
If you set 0.00 (h.mm) as a time value for the maintenance alarm, it will be disabled.
This is reported by the pump as follows:

Audio signal via the buzzer (if there is one on the pump) if enabled (see A.bu
on the “Settings Menu”) with a
frequency of 1 second on and 1 second off;

flashing red LED;
 “
OFd
” flashing on the display;
In this alarm status the motor is stationary. To disable the alarm, you need to go to the t.F.P entry (pump operating
time) in the Statistics Menu and reset the value.
