- Setting assignment of alarm output terminals
Initial setting: 0 Setting range : 0-3
Alarm output terminals output once an alarm is detected.
This is to assign the terminals for each alarm.
0 : Monitoring of alarm outputs
1 : Monitoring of cooling operation and alarm outputs
2 : Monitoring of need for power shutdown and restoration
in the event of alarm output
3 : Monitoring of continued operation when an alarm occurs
Note: See page 11 and 12 for the details.
- Choice of switching method of alarm output terminals
Initial setting: 0 Setting : 0, 1-
This enables inversion of switching OPEN/CLOSE of output
terminals.
0 : Output occurs as set in the assignment setting of
alarm output terminals
1 : Reverse action to 0 occurs, however this does not effect
between terminals 2 and 3 when AS setting is 1.
Note: See page 11 and 12 for the details.
- Setting of operation mode Initial setting: 1 Setting range : 0-3
This is to set operation mode of COOLCABI.
terminals for each alarm.
0 : Continuous run
1 : Energy-saving mode 1
2 : Energy-saving mode 2
Note: See page 13 and 14 for the details.
3 : Energy-saving mode 3
- Setting of cooling operation time for energy saving mode 3
Initial setting: 7 Setting range : 7-60 minutes
This is to set the cooling operation time when energy-saving
mode 3 is selected.
Note: This appears when rM is set at 3.
- Setting of shutdown time for external fan and compressor
Initial setting: 3 Setting range : 3-10 minutes
This is to set the time period for restarting the compressor after
shutdown. For prevention of frequent ON/OFF of the compressor,
cooling operation is suspended during the set period.
- Display of software version
This is to display the software version. Unable to change the setting.
4-6 Assignment of alarm output terminals
Alarm output terminals output once an alarm is detected. By setting the alarm
output terminals, monitoring of many different operations is enabled.
This setting functions by changing AS and Ao. Before supplying power to
the cooling unit, both of terminals 1-2 and terminals 2-3 are open. The time
lag between power input and the change-over of the terminals is 0.8 seconds.
(1) Monitoring of alarm output [AS:0] [Initial setting]
Change over the output in the event of alarm.
(2) Monitoring of cooling operation and alarm output [AS:1]
Change over the output when cooling operation is done and in the event of alarm
(3) Monitoring of need for power shutdown and restoration in the event of
alarm output [AS:2] This helps to determine whether power shutdown
and restoration is required to cancel the alarm, or automatic or manual reset
is enabled without power shutdown.
(4) Monitoring of continued operation when an alarm occurs [AS:3]
This helps to determine whether or not to continue cooling operation.
When you finish the setting, press SET button for 3 seconds or more. The display shows the
current internal temperature again and the setting is stored.
When no button is pressed for more than 30 seconds during parameter setting, the screen
displays the internal temperature again. To continue parameter setting, keep pressing SET
button for 3 seconds or more.
