3.2. Device operation
The idOil Solar remains deactivated most of the time, which means that it consumes very
little power. The device initiates at predetermined measurement intervals, in order to
perform the sensor measurements. When equipped with a 3G modem, the device also
starts listening at predeterminined intervals, to receive any possible setting commands and
simultaneously reports measurement values.
In case of an alarm, idOil Solar will either initiate a flashing beacon, or sends a
text message (SMS) to pre-set phone numbers, or both. All alarms are also visible locally, in
the idOil Solar Control Unit, during the short wake-up period.
The system's power consumption depends on the pre-set measurement and transmission
intervals, as well as the number of alarms.
More information about the device operation is available in the Operation chapter.
3.3. System components
The idOil Solar Control unit consists of a lockable IP65 polycarbonate housing, containing a
solar panel, idOil-30 Battery Control Unit with an in-built charge controller, a lead acid
battery (12 V / 7 Ah) and a main switch.
Any combination of fail-safe idOil-sensors, namely the idOil-OIL oil sensor, idOil-SLU sludge
sensor and idOil-LIQ high liquid level sensor, can be connected to the system. The standard
sensor cable length of a sensor is 5 meters and extendable to at least 500 meters.
Each alarm unit and sensor combination can be equipped with a 3G communication
module, a flashing Xenon beacon or both.

3.3.1. Solar panel and battery
The solar panel charges the lead acid battery which powers the idOil-30 alarm unit.
Charging of battery is controlled by an idOil-30 built-in solar panel charge controller.
In normal use (under factory settings) there is no need to recharge or replace the battery
during its natural life time, due to the sophisticated low-power function of the system.
Battery life is normally about 5 years.
Installation and Operating Instructions | idOil Solar 8/58
DOC001599-EN-3

The idOil Solar will function for at least 6 months without any sunlight. When the idOil Solar
is equipped with a xenon beacon, the operational time will be much less in case of an alarm
(see Xenon beacon below).
Please note that the battery life, and operational time of the idOil Solar depends on many
things, such as the amount of solar energy per day and previous days, temperature, battery
age and the idOil Solar system settings. Operational times presented in this document are
best estimates in particular cases.
3.3.2. idOil-30 Battery Control Unit
The idOil Solar operations are controlled by the idOil-30 Battery or idOil-30 Battery 3G
control unit. The idOil-30 takes care of the low-power system functions, measures
sensor, and controls the flashing beacon and 3G communication functions. The idOil-30
Battery includes a built-in solar panel charge controller, which takes care of the solar panel
and battery charging.
The idOil-30 is an Ex-barrier and power supply unit for the sensors in oil and sand
separators.
The idOil-30 Battery 3G version includes a built-in 3G modem and an external 3G antenna.
A separate external antenna is also an option, if signal quality is a problem. The user is able
to set and modify the settings of the device via text messages (SMS).
The idOil-30 operational settings are pre-set at the factory. The factory settings can be
changed via the in-built browser user interface. The browser user interface is accessible via
local WLAN connection between the control unit and a smartphone, tablet or laptop. For
more information, see idOil-30 installation and operating instructions DOC001699.

3.3.3. idOil-OIL Oil Sensor
The idOil-OIL oil sensor is installed into the light liquid storage
chamber and gives an alarm when the chamber is filled to a
pre-determined level. The sensor is normally fully immersed in
water.
Insert the sensor into the separator using the access point
provided by the separator manufacturer. The sensor gives an
alarm, at the earliest when the upper electrode is in oil, and at
the latest when the sensor is totally immersed in a non-
conductive liquid . In other words, it is totally separated from
the water.
The sensor can be mounted suspended by a cable from the
ceiling of the separator. Please check the correct installation
depth from the instructions of the oil separator as well.
The function is based on the measurement of the electrical
conductivity of the surrounding liquid – water conducts
electricity more efficiently than oil.
The idOil-OIL sensor can be installed in a zone 0, 1 or 2 potentially explosive (Ex) area,
e.g. oil separator.
3.3.4. idOil-SLU Sludge Sensor
The idOil-SLU sensor is installed in the separator or tank and it
gives an alarm when sludge reaches the sensor. The sensor is
normally immersed in water.
The idOIL-SLU sensor gives an alarm when there is enough
sand or sludge accumulated between the two heads of the
sensor. When the sludge layer on the bottom of the separator
or settling tank is pretty solid, the correct installation depth can
be adjusted, based on the current level. In the event that the
level is not clear, a trest period of a couple of days may be
useful.
The sensor can be mounted suspended from the ceiling of the
separator by cable. Please refer to the oil separator
instructions for correct installation depth.
The principle of measurement is ultrasonic. When sludge, sand
or other solid particles accumulate between the two sensor
heads, the signal strength weakens, an alarm is given.
idOIL-SLU sensor can be installed in zone 0, 1, or 2 potentially explosive atmospheres.

DOC001599-EN-3

3.3.5. idOil-LIQ High Liquid Level Sensor
The idOil-LIQ sensor is installed above the separator outlet’s
upper level. It monitors the total level of the separator,
regardless of the existence of the oil layer or sludge in the
separator.
The sensor can be mounted suspended from the ceiling of the
separator by the cable. Please check the correct installation
depth from the oil separator instructions.
The principle of measurement is ultrasonic. The sensor is
normally mounted in the air.
idOIL-LIQ sensor can be installed in a zone 0, 1 or 2 potentially explosive atmosphere.
3.3.6. Flashing Beacon
The idOil Solar can be equipped with a flashing beacon for
visual alarms. In case of alarm, a highly visible signal
flashes once every 10 seconds.
The beacon is mounted on the top of the idOil Solar enclosure.
The beacon is IP67 rated.
In case of an alarm, the idOil Solar can operate the flashing the beacon for about 10 days
with no sun-light, before the battery becomes discharged. In practise, there is always some
solar power available, so the idOil Solar may function much longer with no interruption.
3.3.7. Main Power Switch
The main power switch is located inside of the idOil Solar enclosure (see figure System
components). Main switch connects and disconnects both battery terminals and the solar
panel of the system.
The main power switch must be in ON position during normal low-power operation. The
switch is in OFF position during delivery.

4. Installation
4.1. Installing idOil Solar Control Unit
idOil Solar control unit can be wall mounted or installed on a pedestal. The enclosure has
mounting holes at each of the corners beneath the mounting holes of the front cover.
For pedestal installation, idOil Solar is equipped with a connector flange (see Appendix
Connector Flange).
Orientate idOil Solar as accurately as possible towards south and direct sunlight. Check the
best possible installation angle (e.g. 68°) at your site. Pedestals or other mounting
equipment are not delivered with the device.
All wiring, except sensor cables, of idOil Solar is done already at the factory.
The control unit must be installed in a safe (non-Ex) space.
4.2. General installation instructions for sensors
idOil sensors can be installed in zone 0 explosive atmospheres. Do not remove the sensor
markings from the cables or sensor frames.
Read Section General safety instructions before installation.
Check the correct installation depth of the sensor in the instructions of the separator in
question.
For example, sensors can be installed suspended from their cable (see next figure). Leave
a sufficient length of the sensor or extension cable coiled inside the service well, so that
you can easily lift the sensor out for inspection and cleaning.

4.2.1. 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.
Overflow is possible in the following cases, for example:
if the filter is dirty
if the automatic closure device is blocked
or if some other situation causes blockage in the discharge pipe

4.2.2. Installing the idOil-OIL sensor
The sensor must be submerged at the desired installation depth when the liquid is at the
separator’s standard liquid level (L).
The exact installation depth depends on the following:
separator type
separator shape
volume and height of the separator’s oil compartment
The sensor must always be immersed in liquid. The alarm is activated when the lower
surface of the oil layer reaches the alarm switching point (S), i.e. when the sensor’s
measuring electrode is covered in oil.
The sensor activates the alarm when it is in contact with air. For this reason, the separator
must always be filled with water after draining.
