3.2.1
NOTE : 1. Even if the sensor output exceeds the threshold on
the gas leak sensor monitor screen, a leak error will
not occur.
2. The gas leak sensor output may vary slightly
according to the environment of the installation room
even if a leak has not occurred. The output is
normally adjusted to indicate a range of 200 to 800
in an environment containing air alone. If the output
fluctuates largely from this range, then the threshold
must be adjusted.
3. Since the leak sensor output is unstable for about
five minutes after turning ON the power switch, leak
detection cannot be made during this while.
(2) Set the ON/OFF status of the liquid leak sensor.
(ON status, or use of the leak sensor is set immediately
after turning on power supply again.)
