ALARM 1 = Dry running. Set off after 7 sec. of absence of water in suction.
Check the presence of water in aspiration and fill the pump.
DG PED will effect automatic attempts to restart after 1 min, 15 min, 30 min,
1 h, 1 h, etc.
ALARM 2 = The pump does not reach the set pressure. Contact a repair centre.
ALARM 3 = The pressure of the pre-load of the vase is too low; inflate the vase to 50% of
the work pressure (eg. if one works at 3 bar inflate the vase to 1.5 bar).
ALARM 4 = Discharge pressure less than 0.2 bar (broken tube), the reset is only manual.
Verify why the pressure has fallen to zero.
ALARM 5 = Supply voltage is too low.
Guarantee an electric current of 230 v. +/- 10%.
ALARM 6 = External OFF signal.
ALARM 1 = Short Circuit. Switch off the device and contact a repair centre.
Reset is only manual.
ALARM 2 = Too high a current. The current absorbed exceeds the permitted tolerance.
Reset is only manual. If the problem persists contact a repair centre.
ALARM 3 = Excessive temperature of the module. If the temperature of the liquid is
greater than 40°C. contact a repair centre. Control the temperature of the
pumped liquid.
Automatic reset if the temperature falls below the value of the alarm.
ALARM 4 = Excessive temperature of the motor. If the liquid does not have a tempera-
ture greater than 40°C. contact a repair centre. Control the temperature of
the pumped liquid.
Automatic reset if the temperature falls below the alarm setting.
ALARM 5 = Invalid signal of the pressure sensor. Contact a repair centre.
ALARM 6 = Invalid signal of the flow sensor. Contact a repair centre.
