8 Time Delay
of Electric
Devices
1. F-FAN time delay in Comp On/Off
1) During normal running : F-fan will be On/Off
for five secs. In Continuous 1 min.
after Comp On/Off
2) When initial power input : F-Fan will be ON 4 mins.
After Comp On
2. F-FAN TIME DELAY BY DOOR S/W
1) After 6 mins.of initial power input.
OPEN DR S/W -> CLOSE : F-fan work delay for 20 secs.
2) Before 6 mins. of initial power input.
OPEN DR S/W -> CLOSE : F-fan work for 20 secs.
immediately.
3) when it has nothing to do with Initial power input.
OPEN DR S/W -> CLOSE : F-fan changes into be Off.
immediately.
9 Option Circuit 1
(Weak Refrigeration)
1.Option for Weak Refrigeration,Service Reference
1) When Weak Refrigeration occur,it's easy to find solution
by this.
2) Regulation of R-Sensor Off point ( -1.5 deg Down )
2.In case of Weak Refrigeration, take action as followings.
1) Resistance (R31): Standard Resistance
of R-Sensor middle-off point
in case of Normal Run
(31.4
= -1.0 )
(25.2
= 4.0 )
When change resistance 31.4 into 25.2 ,
R-sensor middle-off point will be 5.0 deg
2) Resistance (R32) : Standard resistance to make
R-Sensor Off Point in case of
Weak Refrigeration.
- R32 2.15 : R-Sensor Off Point will be down by 1.5deg
- R32 6.19 : R-Sensor Off Point will be down by 4.0deg
3) SW 1 : If SW1 is off in Service, R Sensor Off Point
will be down by 1.5deg.
R31 + SW 1 ON: Middle Off Point: 0.5
( In Normal Run )
R31 + SW 1 OFF: Middle Off Point:-1.0
( In Weak Refrigeration )
