
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.
