DEFROST CYCLES
㩵Cycle defrost
When the ambient humidity is high, or a large amount of damp product is being stored inside the chamber, there is a possibility that cycle defrost may not be enough to remove all of the frost on the evaporator. In this case, a forced defrost cycle can be initiated.
㩵Forced defrost
When the unit is operating under a forced defrost cycle, the current chamber temperature and dF is displayed alternately on the digital temperature display. The chamber temperature rises about 10oC during the defrosting.
CAUTION
The unit may collect excessive frost on the evaporator if it is installed in high temperature and high humidity location. For example, the unit starts to defrost once a week with 2oC setting in the ambient of 35oC and 80% R.H. The chamber temperature goes up to approximately 10oC temporarily during
defrosting.
REMOTE ALARM TERMINAL
The terminal of the remote alarm is installed at the back of the unit. The alarm is generated from this terminal. The contact capacity is DC 30 V, 2 A.
Contact output:
| Between COM and N.O. |
At normal condition | “Open” |
At abnormal condition | “Close” |
Note:
The alarm status of remote alarm terminal is cancelled by pressing the alarm buzzer stop key (BUZZER) since the remote alarm is operated in conjunction with alarm buzzer.
The remote alarm terminal is in alarm status when the power supply cord is unplugged because it is regarded as a power failure. In this case, the alarm status of remote alarm terminal is not cancelled by pressing the alarm buzzer stop key (BUZZER).
