Note 3: Range change answer-back signal. For this action, the range change must be preset during the setting of input contacts
(see Section 8.6).
Note 4: Calibration gas pressure decrease answer-back signal. Calibration gas pressure decrease must be selected beforehand
during the setting of input contacts.
Note 5: Non-combusted gas detection answer-back signals. "Non-combusted gas" detection must be selected during the setting of
input contacts.
WARNING
Output contact 2 is linked to the detector's heater power safety switch. As such, if output
contact 2 is on, the heater power stops and an Error 1 (cell voltage abnormal) or Error 2 (heater
temperature abnormal) occurs.
