Unless otherwise noted, the pressure unit MPa represents the gauge pressure in this manual.
*Note 1: The values in the parentheses are the maximum operation delay times.
The values have been set to protect the compressor.
*Note 2: Po = Oil supply pressure, Ps = Suction pressure
*Note 3: This alarm stop is set for normal operation. At the time of the start-up of the compressor,
it is not necessary to perform this alarm monitoring after start until 300 seconds.
