7.16 Electronic drainer
This drain consists of a condensate accumulator where a capacitive sensor continuously checking liquid
level is placed: as soon as the accumulator is filled, the sensor passes a signal to the electronic control and
a diaphragm solenoid valve will open to discharge the condensate. For a complete condensate discharge
the valve opening time will be adjusted exactly for each single drain operation. No condensate strainers are
installed. No adjusting is required. A service valve is installed before the electronic drain in order to make
check and maintenance easily.
At dryer start-up verify that this valve is open.
Control panel
Power Led On - drainer ready to work / supplied
Alarm Led Blinking - drainer in alarm condition
TEST Button Discharge test (keep pushed for 2 seconds)
Troubleshooting
Only qualified personnel should perform troubleshooting and or maintenance
operations.
Prior to performing any maintenance or service, be sure that :

no part of the machine is powered and that it cannot be connected to the mains
supply.

no part of the machine is under pressure and that it cannot be connected to the
compressed air system.

maintenance personnel have read and understand the safety and operation
instructions in this manual.
SYMPTOM POSSIBLE CAUSE - SUGGESTED ACTION
 No led lighting up.

Verify that the system is powered.

Verify the electric wiring (internal and/or external).
 Check internal printed circuit board for possible damage.

Pressing of Test button, but
no condensate discharge.
 The service valve located before the drain is closed - open it.
 The dryer is not under pressure - restore nominal condition.
 Solenoid valve defective - replace the drain.
 The internal printed circuit board is damaged - replace the drain.
 Condensate discharge only
when Test button is pressed.
 The capacitive sensor is too dirty - open the drain and clean the sensor
plastic tube.
 Drain keeps blowing off air.  The diaphragm valve is dirty - open the drain and clean it.

The capacitive sensor is too dirty - open the drain and clean the sensor
plastic tube.
 Drain in alarm condition.

The capacitive sensor is too dirty - open the drain and clean the sensor
plastic tube.
 The service valve located before the drain is closed - open it.
 The dryer is not under pressure - restore nominal condition.
 Solenoid valve defective - replace the drain.
NOTE : When the drain is in alarm condition, the diaphragm solenoid valve will open 7.5 sec every 4
min.
