is shown to
indicate overcooling or overheating. HTL and LTL can be set in the PARAMSET – TAlarm
window. The controller automatically shuts down the solenoid valve to stop liquid cooling.
Temperature Deviation Value Alarm: when the temperature measured in the liquid tank is
higher than “Set value of temperature + High deviation value (HDev)”, a warning alarm
displays to indicate over heat. When the temperature measured in the liquid tank is lower than
“Set value of temperature - Low deviation value (LDev)”, the buzzer alarm sounds and a
warning alarm is shown to indicate over cooling. HDev and LDev can be set in the PARAMSET –
TAlarm window. The controller automatically shuts down the solenoid valve to stop liquid
cooling.
Note:
1) Switch OFF and ON the chiller to restart the normal unit working state after an alarm was
activated.
