E27 0 Not operated when changing ranges.
1 Operated when changing ranges.
(Note 3)
Warm-up E28 0 Not operated during warming up.
1 Operated during warming up.
Calibration gas
pressure decrease
E29 0 Not operated while a calibration gas pressure decrease contact is
being closed.
1 Operated while a calibration gas pressure decrease contact is being
closed.
(Note 4)
Unburnt gas
detection
E32 0 Not operated while a unburnt gas detection contact is being closed.
1 Operated while a unburnt gas detection contact is being closed.
(Note 5)
Note 1: Output contact 2 remains closed.
Note 2: The oxygen concentration alarm must be preset (see Section 8.4).
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.
