2. SAFETY INSTRUCTIONS
Please check whether or not these
instructions correspond to the device
type.
Adhere to all advice given in these
operating instructions. They include
essential information which must
be observed during the installation,
operation and maintenance. Therefore it is
imperative for the service technician and
the responsible operator / technical sta
to read these operating instructions prior
to installation, start-up and maintenance.
The operating instructions must be
accessible at any time at the place of
application of the ENL 10.
In addition to these operating instructions,
local or national regulations must be
complied with, if necessary.
Make sure that the ENL 10 is operated
only within the permissible limit values
indicated on the ID plate. Any deviation
involves a risk for persons and materials,
and may result in malfunction and service
failures.
If you have any queries regarding these
installation- and operating instructions,
please contact Ingersoll Rand.
DANGER
Compressed air!
Risk of serious injury or death through contact
with quickly or suddenly escaping compressed air
or through bursting plant components or plant
components which are not secured.
Measures:
Do not exceed the maximum operating pressure (see
type plate).
Only carry out service measures when the system is
pressure less.
Use pressure-resistant installation material only.
The feed pipe must be tubed rmly. Discharge pipe:
short, xed pressure hose onto pressure-resistant pipe.
Make sure that persons or objects cannot be hit by
condensate or escaping compressed air.
DANGER
Supply voltage!
There is the risk of an electric shock involving injury or
death when coming into contact with
non- insulated components carrying supply voltage.
Measures:
During electric installations, all regulations in force
need to be adhered to (e.g. VDE 0100 / IEC 60364).
Service measures must only be undertaken when
the system is deactivated.
The removed control unit has no IP degree of
protection.
All types of electrical works must be carried out by
authorized and qualied personnel only.

Further safety instructions:
For installation and operation, the national regulations
and safety codes in force must also be adhered to.
Do not use the ENL 10 in hazardous areas.
Regarding the inlet screw joints, excessive tightening
forces must be avoided. This applies in particular to
conical screw joints.
The ENL 10 will only function when voltage is applied.
Do not use the test button for permanent drainage.
Use genuine spare parts only. This is imperative to
ensure perfect functioning.
Additional advice:
During installation, use spanner at at the feed pipe
(wrench size SW27) as a back rest.
The service unit must not be dismantled.

CAUTION
Malfunction during operation!
Through incorrect installation and poor maintenance,
malfunction may occur at the ENL 10.
Condensate which is not discharged may cause damage
to plants and in production processes.
Measures:
Condensate drainage which is reliable in performance
directly optimizes the compressed-air quality.
To prevent damage and breakdowns, it is imperative
to observe the following:
Exact compliance with the specications of use
and with the performance parameters of the
ENL 10, in connection with the case of application
(see“Proper use”section)
Exact compliance with the installation- and
operation instructions in this manual
Regular maintenance and control of the ENL 10 in
accordance with the instructions in this operating
manual.

3. PROPER USE
The ENL 10 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 10 is able to drain condensate under
operating pressure from the plant components
virtually without compressed-air loss.
For its function, the ENL 10 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.
For the employment in CO2 plants, a ENL 10 with a CO
specication must be used.
•
•
4. EXCLUSION FROM THE SCOPE OF APPLICATION
The ENL 10 as a condensate drain alone cannot
guarantee a dened compressed-air quality, for
this purpose, other additional technical devices are
required.
ENL 10 is not suitable for use in plants carrying
vacuum or atmospheric ambient pressure or in ex-
areas.
ENL 10 must not be exposed to permanent direct solar
•
•
•
or thermal radiation.
ENL 10 must not be installed and operated in areas
with an aggressive atmosphere.
The ENL 10 is not heatable and, therefore, not suitable
for the use in areas where frost is likely to occur.

8. FUNCTION
Via the inlet line (1) the condensate ows into the ENL 10
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 10 is empty, the outlet line is reclosed tightly
in time before unnecessary compressedair losses occur.
At the ENL 10, two LEDs indicate the individual operating
states.
When applying supply voltage, the ENL 10 carries out a self-
test.
Both LEDs are lit for approximately 1 second, subsequently,
the device changes over to the “ready-to-operate” state.
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.

Switching sequence of the valve in the alarm mode.
Trouble indication via a potential-free contact
Alarm mode:
In the event that the condensate discharge is disturbed, the
valve opens after a time cycle (approx. every three seconds)
to eliminate the malfunction automatically. If the malfunction
is not eliminated 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
10 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
Frozen pipe work

8. FUNCTION
The ENL 10 releases a maintenance message for a service
that is to be carried out.
Depending on the operating mode, a visual maintenance
message (service) is activated which signalizes the
replacement of the service unit.
The maintenance message is indicated by the ashing
supply voltage-LED “Power”.
The maintenance message is released after 2 x 8,760 h or
one million switching cycles.
The maintenance signal is released when one of these two
values is reached.
In the event of a power outage or when the energy supply is
deactivated, the status of the timer will be maintained.
The activities to be carried out regarding maintenance are
described in the chapter entitled“Check and maintenance”.
Prior to the replacement of the service unit, a reset needs to
be carried out. The control unit is released by actuating the
arresting hook. When removed, the TEST button must be
pressed and held for at least ve seconds.
