1. Safety
1.1 Safety instructions
Make sure that any persons installing, taking into
operation and operating the safety detector:
• Are technically qualified and competent
• Fully comply with these assembling instructions
Improper operations or misuse could cause danger to:
• life and limb
• to the equipment and other assets of the operator
• to the equipment proper function
Opening of the device will void your warranty.
Safety instructions in this manual are shown in three
different forms to emphasize important information.
1.2 Specified applications
The RIS2 integrated safety detector is composed by
a rugged plastic body, watertight and resistant to
extreme climates, with houses a series of
instruments and keeps constant control of the
following operating conditions of the transformer:
• Pressure
- Pressure switch: closes/opens a circuit on
pressure ranging (from 100 up to 500 mbar)
THIS INFORMATION INDICATES PARTICULAR
DANGER TO LIFE AND HEALTH. DISREGARDING
SUCH A WARNING CAN LEAD TO SERIOUS OR
FATAL INJURY .
THIS INFORMATION INDICATES PARTICULAR
DANGER TO EQUIPMENT OR OTHER PROPERTY
OF THE USER. SERIOUS OR FATAL INJURY
CANNOT BE EXCLUDED.
THIS NOTES GIVE IMPORTANT OR SPECIFIC
INFORMATION CONCERNING THE EQUIPMENT
OR AS TO WORK WITH THE EQUIPMENT.
WARNING
CAUTION
CAUTION
INSTALLATION, ELECTRICAL CONNECTION AND
FITTING THE DEVICE MAY ONLY BE CARRIED
OUT BY QUALIFIED PERSONNEL AND ONLY IN
ACCORDANCE TO THIS INSTRUCTION MANUAL.
IT IS RESPONSIBILITY OF THE USER TO MAKE
SURE THAT THE DEVICE IS USED FOR SPECIFIED
APPLICATION ONLY.
FOR SAFETY MATTERS, PLEASE AVOID ANY
UNAUTHORIZED AND IMPROPERLY WORKS.
NOTE
• Temperature
- Thermometer: visual indication of oil
temperature and max. temperature reached
- “T2” Thermostat switch: (alarm) closes/opens a
circuit at a predetermined temperature level
(from 30°C up to 120°C)
- “T1” Thermostat switch: (stop) closes/opens a
circuit at a predetermined temperature level
(from 30°C up to 120°C)
• Oil level
- Indicator: visual indicator of slight oil level
variation
- Detector: visual detector of significant oil level
variation through closing/opening of an electric
circuit
• Gassing
- Detector: closes/opens a circuit when the max.
gas volume is reached (max. 170 cm3)
It is important to observe the limit values indicated
on the nameplate and in the operating instruction
before commissioning the device.
1.3 Safety notes on the
equipment operation
Electrical installation is subject to the relevant
national safety rules.
It is mandatory to connect the grounding cable
because of safety reason.

2.1 Introduction
Different functions efficiently combined
in a single compact design
Integrated safety detector Comem RIS2 was
conceived from the need to integrate the functions
performed by a number of transformer accessories
Integrated safety detector according to EN 50216-3
in a single, compact and reliable instrument, which
was capable of replacing their applications, as well
as guaranteeing numerous advantages ranging
from an economic to functional-aesthetic viewpoint.
2.2 Description and functions
Description and functions Measure Checking test value
Oil level (Float)
The device indicates any gas evolvement or oil level variation.
- Slight oil level variation or any insignificant gas evolvement is denoted by the
float position between “MIN” & “MAX” on the display.
- At major oil variation level or gas evolvement the float stops at “MIN” and
opens/closes the alarm circuit.
- Any accumulated gas can be drawn off by the valve provided.
Max 150 cm3 Locate the magnet close to the
float (between MAX and MIN).
Drawn it downwards until it
reaches “MIN”. To reset the
float to its correct position
draw the magnet upwards and
detach.
Pressure (Pressure switch)
This feature measures the internal pressure of transformer. The normal level is
to be set by the user according to the transformer manufacturer’s instructions.
When pressure exceeds a pre set level the alarm circuit is triggered by a change
over contact.
100 mbar to
500 mbar
With the internal pressure at
least 100 mbar set the
adjusting knob of the pressure
switch to minimum.
Temperature
“T2” Thermostat switch (Alarm)
The feature measures the internal oil temperature of the transformer.
The normal operating value is to be set by the user according to the transformer
manufacturers instructions. At a pre set temperature the alarm circuit is
triggered by a change over contact (T2).
30 °C to 120 °C Open the rear cover using both
hands, do not lever at one side
only. The adjustment knob of
the alarm switch “T2” should
be set to the minimum value.
“T1” Thermostat switch (Stop)
The feature measures the internal oil temperature of the transformer.
The normal operating value is to be set by the user according to the transformer
manufacturers instructions. At a pre set temperature the stop circuit is
triggered by a change over contact (T1).
30 °C to 120 °C The adjustment knob of the
stop switch “T1” should be set
to zero. The adjustment knob
of the stop switch “T1” should
be set to the minimum value.
Thermometer
The device measures the internal temperature of the transformer, which shall be
visualized outside the device through the protection window.
The thermometer is equipped with a drag pointer.
30 °C to 160 °C The protection window is to be
unscrewed so that the pointer
shall be set to the minimum
values.
