Operation and maintenance

The pressure relief device is ready for operation after
installation and electrical connection.
Pull the signaler out of the housing to check the fun-
ction-ing of the switches; press then the signaler back into
the housing to deactivate the switches.
Operation
If the optical signaler is in the normal operating position,
the pressure relief device has not been tripped. If the
micro-switches report a signal anyway, the cause could
be in the tripping circuit. In this case, check the tripping
current circuit.
If the optical signaler is in the "alarm" operating position,
the pressure relief device has been tripped.
If the micro-switches don't report a signal, the cause could
be in the tripping circuit. In this case, check the tripping
current circuit.
All the external parts are resistant to transformer oils, salt fog and UV rays.
The housing flange and the cover are die-cast aluminum.
The protection is in plastic material.
The duct is in AISI316 stainless steel.

Maintenance
Regular maintenance is not required.
We recommend inspecting of the external condition of
the built-in device for damage and dirt. Remove dirt as
necessary.
Storage
The pressure relief device storage has to be done in its
packaging, in dry place with temperature in the range
-10°C ÷ +40°C.
Upon receiving the pressure relief device, please check:
• the outer surface of the packaging to check that it is intact;
• that there are no breakages.
If damages are found, please contact COMEM, quoting the
data provided in the shipping list and the serial number of
the pressure relief device.
