Product description

The RIS2 integrated safety detector is composed by a
rugged plastic body, watertight and resistant to extreme
climates, with a series of instruments which keep con-
stant 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).
• 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 the closing/opening of an electric
circuit.
• Gassing
• Detector: closes/opens a circuit when the max. gas
volume is reached (max. 170 cm
WARNING
It is important to observe the limit values indicated on the
nameplate and in the manual before commissioning the device.

Installation

Mounting instruction

Application to a transformer tank
• Ø 60 mm ± 1 mm diam. hole on the tank
• Flat gasket (provided with the unit)
• Stainless steel fixing brackets (4 pcs packed)
• Stainless steel flat washers according to UNI 6592
Ø 8,4 mm (4 pcs packed)
• Stainless steel spring washers according to UNI 1751
Ø 8,4 mm (4 pcs packed)
• Stainless steel M8 nuts according to UNI 5588
(4 pcs packed).
Tighten the nuts in position 1,2,3,4 with torque nut 3 Nm
to 4 Nm in a cross pattern; repeat the operation following
the same sequence until the suggested value (6 Nm to 8
Nm) is reached.
Due to the deformation of the cover during lifting of the
transformer, an oil leak could be possible. It is suggested
to use covers of suitable thickness (min. 6-8 mm).
