GENERAL INFORMATION
1. Do not exceed max. operating pressure (see type plate).
NOTE: Maintenance work must only be carried out when
the device is not under pressure.
2. Only use pressure-proof installation material.
The feed line (1/2”) must be firmly fixed. Discharge line:
short pressure hose to pressure-proof pipe. Please
ensure that condensate cannot squirt onto persons or
objects.
3. In case conical connectors are used on the inlet side,
avoid excessive tightening of the connectors.
4. For locking or holding in position during installation, use
spanner area at inflow point.
5. The electrical installation must be carried out in compli-
ance with the valid regulations.
NOTE: Maintenance work is only allowed when the device is
in a de-energized condition. Electrical work must always be
performed by a qualified electrician.
6. Do not operate the device when there is a danger of
frost.
7. The Series 600 condensate drain will only function when
voltage is being applied to the device.
8. Do not use the test button for continuous draining.
9. Do not use the Series 600 condensate drain in hazardous
areas (with potentially explosive atmospheres).
10. Only employ original spare parts, otherwise the guaran-
tee will no longer be valid.
1.0 FUNCTION
The condensate flows through the feed line (1) into the
Series 600 condensate drain and accumulates in the hous-
ing (2). A capacitive sensor (3) continuously registers the
liquid level. As soon as the container is filled, a fixed waiting
period begins during which more condensate accumulates.
After the waiting time has expired the pilot valve (4) is then
activated and the diaphragm (5) opens the outlet line (6) for
discharging the condensate.
When the Series 600 condensate drain has been emptied,
the outlet line is closed again quickly and tightly without
wasting compressed air.
Ready for operation / Power on
The operating states of the Series 600 condensate drain are
indicated by two LEDs.
Malfunction / Alarm
If the condensate discharge is not functioning properly, an
alarm mode starts which is indicated by the flashing of the
red alarm LED.
Test function
1. Test of valve function and manual drainage: briefly press
button.
2. Test the alarm function (see below): press button for at
least one (1) minute.
Switching sequence of valve in alarm mode
Alarm signal via potential-free contact.
Alarm-mode function:
If normal conditions have not been restored after 1 minute,
a fault signal will be triggered:
• AlarmLEDashes.
• Alarmsignalswitchesover(canbetransmittedvia
potential-free contact).
• Valveopensevery80secondsforaperiodof60
seconds.
Once the fault is cleared, the Series 600 condensate drain will
automatically switch back to the normal mode of operation.
Malfunctioning could be caused by, e.g.:
• Mistakesduringinstallation
• Droppingbelowthenecessaryminimumpressure
• Excessivecondensatequantities(over-loading)
• Blocked/shutoffoutletline
• Extremeamountofdirtparticles
• Frozenpiping
