SETTING OF DELAY OF DOOR ALARM
The door check indicator is light when the door is opened, and the alarm buzzer sounds with some delay to notice the door opening.
The delay time (between lighting of the door check indicator and activation of the alarm buzzer) can be changed. Set an appropriate delay time according to the condition of use to prevent the rise of chamber temperature resulting from inadequate door close.
(The available set range of delay time is between 1 and 15 minutes. Initial setting (factory setting) is 2 minutes.)
Table 4 Procedure for setting of delay of door alarm (Change the delay time to 3 min. from 2 min.)
