Error E20 0 Not operated if an error occurs.
1 Operated if an error occurs.
High-high limit alarm E21 0 Not operated if a high-high limit alarm occurs.
1 Operated if a high-high limit alarm occurs. (Note 2)
High-limit alarm E22 0 Not operated if a high-limit alarm occurs.
1 Operated if a high-limit alarm occurs. (Note 2)
Low-limit alarm E23 0 Not operated if a low-limit alarm occurs.
1 Operated if a low-limit alarm occurs.
Low-low limit alarm E24 0 Not operated if a low-low limit alarm occurs.
1 Operated if a low-low limit alarm occurs. (Note 2)
Maintenance E25 0 Not operated during maintenance.
1 Operated during maintenance (see Section 8.2.1).
Calibration E26 0 Not operated during calibration.

Warm-up E28 0 Not operated during warming up.
1 Operated during warming up.
Calibration-gas E29 0 Not operated while a calibration-gas pressure drop contact is being closed.
pressure drop 1 Operated while a calibration-gas pressure drop contact is being closed. (Note 4)

T8.10E.EPS
Note 1: Output contact 2 remains closed.
Note 2: For the high-high alarm, the concentration alarm must be preset (see
Section 8.3).
Note 3: Range change answer-back signal. For this action, the range change must be
preset during the setting of input contacts (Section 8.5).
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.
