Preface
This service manual explains about the cautions for maintenance jobs and is to serve a
guide for the electric system, and troubleshooting for service personnel. Fundamental
matters and other things already mentioned in the “Instruction Manual” and the “Parts
Catalogue” are omitted to avoid duplication. Therefore, for the operation and handling of
this unit, we request you to refer to the instruction manual and caution plates, and
further for the structure and components of the unit, please refer to the “Parts
Catalogue” separately to be supplied with the unit.
If you should find any description which does not coincide with the instruction manual
and parts catalog, we request you to make sure to start the job after clarifying it.
Service personnel is required to safely take quick and proper countermeasures as well
as to use correct technology of maintenance in case of field services and periodical
maintenance. It is important that service personnel should have proper and sufficient
knowledge about the structure and function of the unit and should be well familiar with
such technique mentioned in them.
Regarding the part numbers mentioned in this manual, we request you to refer to the
Parts catalogue separately supplied together with the unit, because the parts numbers
in this manual are sometimes changed.
Copies of this service manual are intended to be distributed to limited numbers
of our customers. The unauthorized reproduction or distribution of this service
manual is prohibited.

1.6 Capacity Control Device
PC13052-3E
Step Response
Start
Compressed air is sent into the unloader chamber through starting
unloader solenoid valve SV1 to fully open the unloader valve. Further, as
COM-NC for the solenoid valve SV2 is connecting, the spring chamber becomes
negative pressure, and unloader valve fully closes at lower pressure. Thus
starting unloader operation is performed.
●In cold seasons, it opens the low temperature starting valve, and it sends
compressed air in separator receiver tank into the unloader and the unloader
valve can be fully closed at low pressure. Thus, the load for starting can be
reduced.
●SV1 and SV2 solenoid valves operate 30 seconds at the discharge air
temperature of higher than 10℃, and the temperature should be higher than
10℃or it operates 120 seconds.
●Engine (revolution) speed is fixed at 1,600min-1 for the above mentioned
operation conditions.
Load operation
So that SV1 and SV2 solenoid valves are to be closed, the flow of air sent into
the chamber increases and decreases according to the increase and decrease
of discharge pressure. Accordingly, the position of unloader valve and engine
(revolution) speed change. Automatically discharge air volume can be controlled
steplessly from 0 – 100%.

Step Response
Suction port closing
unload operation
When air consumption decreases and it exceeds the rated pressure, the pressure
regulator operates to close the unloader valve. At the same time, the pressure
sensor provided at the secondary side of pressure regulator detects and sends to
engine controller the signal of engine speed lowering. At the unload condition,
the inside of air end becomes high vacuum and it causes vacuum noise. In order
to prevent this noise, it opens vacuum relief valve to prevent the compressor air
end from becoming vacuum.
●Engine (revolution) speed at unload conditions is operated at 1,600min-1 under
less than discharge air temperature less than 60℃, and when it becomes
higher than 60℃, the speed will be 1,300min-1.
Stop
Detecting the pressure inside compressor air end, the auto-relief valve operates,
and the compressed air in separator receiver tank is automatically relieved to
the atmosphere from unloader primary side.
