High temp. alarm
When internal temperature is higher than high temperature alarm setting value, alarm
lamp flashes, intermittent buzzer beeps with 15 minutes of delay and remote alarm
activates.
Press BUZZER key to stop buzzer beeping. However, buzzer beeps again after Ring
Back time is passed. Remote alarm is still activated during this period.
High temp. alarm setting range: SV+5㷄 ~ +20㷄 (Initial: +10㷄)
Ring Back time setting range: 1 ~ 99 minutes (Initial: 30 minutes)
* 0 minutes = Alarm does not recover.
* Note) During pull-down, both buzzer and remote alarm don’t activate.
(3)
Low temp. alarm
When internal temperature is lower than low temperature alarm setting value, alarm
lamp flashes, intermittent buzzer beeps with 15 minutes of delay and remote alarm
activates.
Press BUZZER key to stop buzzer beeping, however, buzzer beeps again after Ring
Back time is passed. Remote alarm is still activated during this period.
Low temp. alarm setting range: SV-5㷄 ~ -20㷄 (Initial: -10㷄)
Ring Back time setting range: 1 ~ 99 minutes (Initial: 30 minutes)
* 0 minutes = Alarm does not recover.
* Note) During pull-down, both buzzer and remote alarm don’t activate.
(4)
Door alarm
When door is open, intermittent buzzer beeps and ‘DOOR’ at ‘TopScreen’ flashes.
Shut door or press BUZZER key to stop buzzer beeping. Remote alarm does not
activate during this period.
Door alarm setting range: 1 ~ 15 minutes (Initial: 2 minutes)
(5)
Filter alarm
When temperature in filter sensor is equal or higher than +48.0㷄, intermittent buzzer
beeps and ‘FILTER’ at ‘TopScreen’ flashes. Remote alarm does not activate.
Press BUZZER key to stop buzzer beeping. (Buzzer does not recover automatically)
When temperature in filter sensor is equal or lower than +43.0㷄, buzzer stops beeping
and indication is disappeared.
If you set buzzer does not activate, buzzer does not beep.
(6)
Remote alarm
Remote alarm is output from the terminal.
Contact status ‘Normal’: ‘Open’ between COM. and N.O.
‘Close’ between COM. and N.C.
Contact status ‘Abnormal’: ‘Open’ between COM. and N.C.
‘Close’ between COM. and N.O.
*Note) When remote alarm is OFF position at Default setting screen, remote alarm
does not activate. (Initial: 1 (=ON))

3.
Buzzer Auto-recovery (Ring Back function)
You can stop buzzer beeping temporary with BUZZER key pressed. Remote alarm
contact does not activate at the time.
Ring Back setting time: 1 ~ 99 minutes
* 0 minute = Buzzer does not recover if BUZZER key pressed once.
4.
ON/OFF control for Compressor H
Start-up: Compressor H turns on with 2 minutes of delay after the power is supplied.
Compressor H starts with designed delay time after the power failure.
Protection: Compressor H is forcibly turned off when temperature in filter sensor is equal or
higher than +60㷄.
Recovery: Compressor H is turned on when temperature in filter sensor is equal or lower
than AT + 10㷄 and also compressor delay time is passed.
5.
ON/OFF control for Compressor L
ON: When cascade temperature is equal or lower than -34㷄, Compressor L is turned on.
OFF: When cascade temperature is equal or higher than -12㷄, Compressor L is turned off.
Differential: When compressor delay timer is set at ‘0’ and controlled temperature is higher
than SV+0.5㷄, Compressor L is turned on.
When controlled temperature is SV-0.5㷄, Compressor L is turned off.
6.
Monitor of freezer status
(1) Abnormal ambient temperature
When ambient temperature is equal or lower than 0㷄, or equal or higher than +35㷄,
‘Status-1’ is displayed.
(2) Voltage decline
When the voltage decreases in about 170V, ‘Status-2’ is displayed.
When the unit detects above abnormal status, the Status indication flashes on the basic
screen with massage indication.
(3) Compressor running rate
You can see compressor running rate in the indication of MENU/Svc – Status in the
screen of ‘Hardware Status’.
* Running rate of Compressor L
= {Compressor ON time / (Compressor ON time + Compressor OFF time)} x 100 (%)
7.
Control of Cap. tube heater
Cap. tube heater is permitted to turn on once every 18 hours.
Cap. tube heater is forcibly turned on for 8 minutes after compressor L is turned off and
8.
MENU screen
In MENU is displayed on the basic screen, MENU is automatically disappeared if there is not
any key inputs for 1 minute.
In MENU is not displayed on the basic screen, the screen is changed for renewal once every
hours.

9.
Operation in power failure
Unit checks power failure by the port for detecting power failure in every 0.42 seconds.
Operation in power failure;
- All ports for controlling compressor, cap. tube heater, LCD back lamp, signal lines and
digital lock turn off and unit operates to the mode in low power consumption.
- LCD is turned off and intermittent buzzer beeps.
- If you press BUZZER key, buzzer stops beeping, LCD back lamp is lit for 5 seconds
and you can check the time when power failure was occurred. However, buzzer beeps
again after buzzer resume time is passed.
- Log data is stored.
10.
Auto Return
Display changes to the basic screen if there are any key inputs for 90 seconds.
11.
Notice of parts replacement
- Battery replacement: When battery accumulating time is over than 2.8 years,
‘Please exchange batteries’ is indicated.
- Fan motor replacement: When fan motor accumulating time is over than 5.6 years,
‘Please exchange fan motor’ is indicated.
