Connection Positions and Settings
For connection position and setting for each compressor protective device, refer to the instruction
manual of the unit.
Make sure that the set values do not exceed the operating limits shown in Chapter 2, section 2.3.2
and Table 2-2 of this manual.
Inspection Method/Cycle
Compressor protective devices require operation tests and confirmation of the settings calibration
before test run as well as at regular intervals. For information on inspecting procedure and
frequency for the compressor, refer to the instruction manual of the unit.
In the operation test, check that alarms and protective devices operate normally
by using devices such as pressure tester. Do not operate the compressor with all
the valves closed, or in any other dangerous conditions.
If the protection from oil pressure (OP), high pressure (HP) activates, do not
restart operation until the cause of activation is removed.
