(3) Filter sensor
Open circuited: E05 and PV are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
Press BUZZER key to stop the buzzer beeping.
Short circuited: E06 and PV are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
Press BUZZER key to stop the buzzer beeping.
(4) AT sensor
Open circuited: E07 and PV are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
Press BUZZER key to stop the buzzer beeping.
Short circuited: E08 and PV are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
Press BUZZER key to stop the buzzer beeping.
(5) Abnormal
condenser temp.
E10 and PV are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
Press BUZZER key to stop the buzzer beeping.
When E10 is shown on the display, the compressor (H) is forcibly turned
off. When E10 is not shown, the compressor (H) is permitted to turn on.
(6) Error code priority
No.1: Temp. sensor failure (E01 or E02)
No.2: Cascade sensor failure (E03 or E04)
No.3: Filter sensor failure (E05 or E06)
No.4:
No.5:
AT sensor failure (E07 or E08)
Abnormal condenser temperature (E10)
(7) Standard to judge sensor failure
PT sensor:
49.9㷄 or higher with E01 displayed (open circuited)
-170㷄 or lower with E02 displayed (short circuited)
Cascade sensor:
-60㷄 or lower with E03 displayed (open circuited)
60㷄 or higher with E04 displayed (short circuited)
Filter sensor:
-60㷄 or lower with E05 displayed (open circuited)
130㷄 or higher with E06 displayed (short circuited)
AT sensor:
-60㷄 or lower with E07 displayed (open circuited)
60㷄 or higher with E08 displayed (short circuited)
Filter sensor: 60㷄 or higher with E10 displayed
13. Cycle to turn capillary heater on
Cycle: Every 18 hours
Period to turn on: 8 minutes (For factory use, unnecessary to change)
Capillary heater is permitted to turn on after 9seconds later since
compressor L was switched to turn off.
With the compressor L keeps turning on for 60minutes, the compressor L
turns off after 1minute passed then and capillary heater is forcibly turned
on.
14. When the power is supplied (without battery)
Compressor H: Compressor H turns on with 2minutes (initial value) of delay after the
power was supplied. Compressor H runs with regardless of PV.
Compressor L:
In PV䋾SV (when the cascade sensor temperature is -34.1㷄 or lower),
compressor L turns on with 2minutes (initial value) of delay after the
power was supplied.
In PV䋾SV (when the cascade sensor temperature is -34.0㷄 or higher),
compressor L turns on with 2minutes (initial value) of delay after the
power was supplied and cascade temperature is reached at -34.1㷄.
*Note) Delay time of both compressor H and L cannot be set individually.
Setting data: The setting data initialized in F17 is retrieved in non-volatile memory.
