2. How to control
1) Conditions for Low Temp. A
R-Heater Off when Comp On
R-Heater On when Comp Off
20 seconds of preventing time for re-start of Comp
R-Heater Off, if it is not the Low Temp. A or if it is RT-Sensor
Disconnection/Short-circuit)
2) Conditions for Low Temp. B
Middle On/Off Point -1
when Comp is running
7 Initial Defrost-
ing
Defrosting
Mode
1. If D-Sensor temperature
3.5
in the initial power input, normal
defrosting mode begins.
2. It begins in the middle of the mode of Comp re-start prevention.
8 Prevention of
Comp
Comp 1. In order to protect Comp after Comp Off, it does not re-start
for a certain time, though R-Sensor becomes On
2. Re-start Prevention Time
1) In case RT-Sensor temperature
13
(Low Temp. A) : 20 minutes
2) In case RT-Sensor temperature
14
: 6minutes
3) In case RT-Sensor disconnection/short-circuit : 6 minutes
9 Option Circuit Nothing
Concerened
1.Option for Weak Refrigeration
1) Regulation of R-Sensor Off Point
2) In case of Weak Refrigeration, take action as the followings.
Resistance (R16) : Standard Resistance(31.4
) of R-Sensor
in case of Normal Run
Resistance (R18) : Standard Resistance(21.5
) to make R-Sensor
Off Point below 1.5
in case of Weak Refrigeratio
n
SW1 : In A/S, R-Sensor Off Point decreases by 1.5
,
if SW1 is made Off.
R16 + SW1 = Middle Off Point
R16 + R18 = Middle Off Point - 1.5
NO
