Please take note:
This Quick Guide is not a replacement for the manual. It is only a brief
overview of the functions of the alarm system. Detailed information
about the alarm system can be found in the manual. The correspon-
ding safety chapter of the manual is an integral component of this
document. The safety instructions contained therein should be read
and understood.
General Safety Instructions
The responsibility for the design, installation, implementation, opera-
tion, maintenance and dismantling lies with the system operator. The
installation and implementation of all devices must only be carried out
by trained specialist personnel. The protection of operating person-
nel and the system is not guaranteed if the module is not used for its
intended purpose. The laws and regulations applicable to the use or
intended purpose must be observed. The devices are only approved
for proper and intended use. Infringement will void any warranty and
manufacturer’s liability.
Installation of the Alarm System
The device can only be installed outside of potentially explosive areas.
The unit cannot be installed in places where aggressive vapours may
be present. The device must be disconnected from the power supply
during installation and maintenance. The alarm system should only be
connected to the supply voltage after the sensors and relay outputs
have been completely mounted and connected and the protection
cover fitted. The type plate must not be removed.

Connection to Sensors in
Potentially Explosive Areas
In oil/petrol separator systems, only sensors that are approved for
installation in potentially explosive areas can be connected. The safety
class of the external equipment must correspond to the safety class
prescribed for the entire system.
Sensor Cable
Sensor cables cannot be run in cable or conductor bundles together
with other circuits. Avoid running the sensor cable parallel to other
cables from which interference signals can be emitted that could
impair the sensor signal and thus the alarm function. The sensor it-
self cannot be grounded. If you extend the sensor cable, observe the
applicable ATEX regulations with regard to colour, quality, durability.
Use unshielded cable.
Installation in Conjunction with
Intrinsically Safe Circuits
The intrinsically safe circuits of the devices may be routed into poten-
tially explosive areas; careful attention should be paid to ensure they
are safely isolated from all non-intrinsically safe circuits. The installa-
tion of the intrinsically safe circuits must be carried out in accordance
with the applicable installation regulations. For the interconnection of
intrinsically safe field devices with the intrinsically safe circuits of the
associated devices, the respective maximum values of the field de-
vice and the associated device in terms of explosion protection must
be observed (proof of intrinsic safety). In this case, EN 60079-14/IEC
60079-14 must be observed.

1 Installing the idOil-LIQ
high liquid level sensor
The sensor is normally in air, and it issues an alarm when the sensing
element is submerged in liquid. The sensor is installed at a suitable
height above the standard liquid level (L) so that the overflow alarm
is activated once the liquid level reaches the sensing element. Notice
manufacturer´s instructions for oil separators.

2 Installing the idOil-OIL
oil sensor
The sensor must be submerged at the desired installation depth when
the liquid is at the separator’s standard liquid level (L). Notice manu-
facturer´s instructions for oil separators.

5 Commissioning
The front cover of the housing must be
removed. Make sure that the protection
cover (8) is properly attached.
Caution: High voltage!
Warning: Do not touch
live parts!
The „supply voltage on“ LED and the
fault LED light up green. Push the but-
ton (7) on the top PCB briefly. The auto-
matic sensor detection starts and the
fault LED (4) flashes green. Attach the
front cover and lock it in place with the
four plastic screws. After all connected
sensors have been detected, the corresponding sensor LEDs (1), (2), (3)
and the fault LED light up green. In case of an alarm, the corresponding
sensor LED lights up red. In the event of a fault, the corresponding sen-
sor LED flashes red and the fault LED lights up red.
