3. PROPER USE
The ENL 5 is an electronically level-controlled
condensate drain for compressed-air plants.
The device is employed within the permissible
performance parameters (see “Technical data”).
The ENL 5 is able to drain condensate under operating
pressure from the plant components virtually without
compressed-air loss.
For its function, the ENL 5 requires an supply voltage
and an operating pressure (see “Technical data”).
As far as the employment in plants with increased
demands on compressed air is concerned (food
industry, medical technology, laboratory equipment,
special processes etc.), the operator must decide on
measures for the monitoring of the compressed-air
quality. These have an eect on the safety of the
subsequent processes and may prevent damage to
persons and plants.
•
•
•
•
•
It is the task of the operator to ensure that the
indicated conditions are met during the entire
operating time.
The ENL 5 is a condensate drain whose properties are
adjusted especially to prescribed applications.
ENL 5 devices must not be employed at drain points
other than those prescribed by the supplier, as
this may result in malfunction and damage in the
compressed-air system and at the compressed air
consumers.
ENL 5 devices must not be replaced by other
ENL 5 -types, as this may result in malfunction and
damage in the compressed-air system and at the
compressed-air consumers.
•
•
•
•
4. EXCLUSION FROM THE SCOPE OF APPLICATION
The ENL 5 as a condensate drain alone cannot
guarantee a dened compressed-air quality, for
this purpose, other additional technical devices are
required.
ENL 5 is not suitable for use in plants carrying vacuum
or atmospheric ambient pressure or in ex-areas.
ENL 5 must not be exposed to permanent direct solar
or thermal radiation.
•
•
•
ENL 5 must not be installed and operated in areas
with an aggressive atmosphere.
The ENL 5 is not heatable and, therefore, not suitable
for the use in areas where frost is likely to occur.
The ENL 5 is not suitable for CO2 plants.

8. FuNCTION
Via the inlet line (1) the condensate ows into the ENL 5
and accumulates in the housing (2).
A capacitive functioning sensor (3) continuously registers
the lling level and relays a signal to the electronic control as
soon as the container is lled.
The pilot valve (4) is activated and the membrane (5) opens
the outlet line to discharge the condensate (6).
When the ENL 5is empty, the outlet line is reclosed tightly
in time before unnecessary compressedair losses occur.

At the ENL 5 , two LEDs indicate the individual operating
states.
When applying supply voltage, the ENL 5 carries out a
self-test.
Both LEDs are lit for approximately 1 second, subsequently,
the device changes over to the state“ready-to-operate”.
Ready to operate, voltage is applied.
In the event that the condensate discharge is disturbed,
an alarm mode will start which is indicated by
the ashing of the red alarm LED.
Malfunction/alarm
Test of the valve function (manual drainage): press
and hold the button for approximately 2 s.
Test of the alarm function (see below): press and hold
the button for at least 1 min.
Do not use for permanent drainage.

Trouble indication via a potential-free contact
Alarm mode:
In the event that the ENL 5 is not empty after one
minute, a trouble indication is released:
The alarm LED ashes.
The alarm relay switches over (the signal can be picked
o potential-freely).
The valve opens every four minutes for 7.5 seconds.
When the malfunction has been eliminated, the ENL 5
will switch back automatically into the normal mode.
Possible trouble sources include :
Mistakes during installation
Dropping below the minimum pressure
Excessive accumulation of condensate (excess load)
Blocked / obstructed outlet line
Extreme amount of dirt particles
