• Control of starting
FC fan motor is rotated of high speed, for 10 seconds after starting.
• Synchronous control of compressor
FC fan is operated, while compressor is operated.
FC fan is operated, while FC Cooling Mode.
• Control of Door Open/Close
FC fan is stopped while FC door is opened.
• FC fan delay control, when FC defrost is stopped
When Defrost ends, three minutes pass after compressor works, the FC fan does the forcibly stop for six minutes.
• Control of FC Fan rotational speed
High speed drive: DC 12V
Common drive: DC 10V
Stop: 0V
5.7. Compressor Rotational Speed Control
For securing the amount of cooling according to the overload at a high ambient temperature, the rotational
speed of the compressor is changed by difference of temperature between FCC and FC Control setting, PCC
and PC Control setting.
Detection : FCC, PCC, ATC sensor
5.7.1. Normal time
• The judgment of compressor ON: FCC is ON temperature or above
or
PC and FC Cooling Mode
• The judgment of compressor OFF: While FC is cooling FCC is OFF temperature OFF or above
While power is turning on of FC Defrost Heater,
While waiting of compressor start.
5.7.2. The use rotational speed
• The rotational speed of compressor is changed by deference between FCC temperature standard value (ON tempera-
ture) and FCC temperature, PCC temperature standard value and PCC temperature.
The rotational speed according to ambient temperature is as follows, it doesn't drive in other rotational speeds.
• The use rotational speed
• The use rotational speed according to ambient temperature is as follows
