Safety instructions
Depressurize the system before carrying out any work on the piping.
Installation and maintenance work may only be carried out when the device is
not under pressure.
Installation and maintenance work may only be carried out by trained and
experienced staff.
Disconnect power supply before installation or any maintenance work.
Electrical work must always be carried out by qualified electrician.
Do not exceed max. operating pressure or operating temperature range (see
data label).
Do not use the device in hazardous areas with potentially explosive
atmospheres.
Use original spare parts only.
Use the device for the appropriate purpose only.
Appropriate use
ECD series electronic condensate drain is intended exclusively for the following purpose:
Draining condensate from compressed air system (air compressors, air
receivers/pressure vessels, air dryers and air filters).
Any other form of use or one going beyond this shall be considered as inappropriate. We
shall have no liability whatsoever for any damage incurred as a result.

Operating
Condensate flows through inlet connection (1) and accumulates in the reservoir (2). Sensor
(3) is measuring condensate level. When reservoir (2) is detected full sensor (3) sends signal
to electronic board. Electromagnetic valve (4) is than opened to discharge accumulated
condensate through outlet connection (5). When reservoir (2) has been emptied, the valve
(4) closes back without any losses of compressed air.
Led signal is indicating status of the device (see Functions).
If microcontroller registers faulty operation, device goes to alarm mode. At the same time
signal is sent through voltage free contact (see Functions).

Installation
Inlet pipe (1) size at least ½” (inner diameter > 13mm).
Collecting condensate line (3) size at least ¾ “.
At least 1% inlet pipe slope recommended.
Install ball valves (2) only.
Recommended connection (4) to water/oil separator.

The inclination of the unit must not exceed + / - 5° in both axes. If device is not installed
correctly it could cause faulty detecting of condensate level.

Connecting several condensate sources to one drain device causes operating problems (3).
Make sure that each drain source has its own drain device (4).

Trapped air prevents the condensate being purged from drain (5). During installation ensure
that no water pockets are formed in the piping (6).

When drainage is to take place directly from a pipeline it is recommended to arrange the
piping so that air flow is diverted (8).

In case there are problems with inflow, it is necessary to install a venting line (12). In this
case back
connection is used as inlet and upper connection is used as air ventilation. Venting
line must never be installed as it is on pictures 9, 10 and 11.
Warning: Upper and back connections cannot be used as condensate inlet at the same
time.

Electrical wiring
Please ensure that the installation is carried out according to the valid regulations
After installation or maintenance, the test button should be pressed to empty condensate that has been
collected while the ball valve has been closed.

Functions
LED indicator / TEST button
Power on
At power on there are few short green
flashes. These tell us ECD type.
1. One flash: ECD 15B
2. Two flashes: ECD 40B
3. Three flashes: ECD 90B
4. Four flashes: ECD 150B
Operating
LED indicates a condensate sensor output.
1. Green FLASHES: Sensor detects no
water
2. Green ON: Condensate is detected
3. Red ON: Alarm mode
Short flashes of red light indicate a
production mode. In this case, you should
contact producer.
By pressing TEST button valve opens.

Operating modes
NORMAL
When sensor detects condensate the valve opens up to one second to discharge. The exact
period depends on type of a drain. Minimal time between two discharges is 5 seconds.
OVERLOAD
If sensor detects condensed water continuously for 90 seconds, drain enters overload mode.
In this mode, the valve is opened longer and the time between discharges is shorter.
Therefore, the amount of discharged condensate is doubled. This mode lasts for five
minutes. In case the reservoir empties during overload mode, the drain enters normal mode
again. Otherwise, it goes into alarm mode.
ALARM
If drain was still not able to discharge all condensate it enters alarm mode. In this mode, the
valve is opened for five seconds every half minute. In case the reservoir empties during
alarm mode, drain enters normal mode again.
Alarm output
The ECD comprises an alarm output that is voltage free. The output is connected to the red
signal logically. The output is in high impedance state when the red LED is on or when ECD
electric supply is off.

Maintenance
Service:
It is recommended to clean/change internal strainer and clean reservoir at least once a year.
Sealing elements are subject to wear, which depends on various operating parameters such
as pressure, temperature, dirt content, etc. It is also recommended to change sealings.
Attention
Before beginning maintenance work take the drain out of operation, cut off the power
supply and depressurize the unit.
