The coils for transducer 1 are shown in the following table:
Coil
Name
Comments
Measurement
101
Calibration mode on/off
0 = off (normal), 1 = on (alarms masked,
jamming etc).
Write 1 to turn calibration mode on.
102
Low calibration gas
0 = sample gas, 1 = low calibration gas.
103
High calibration gas
0 = sample gas, 1 = high calibration gas.
104
Low calibrate
0 = idle, 1 = low calibration in progress.
Write 1 to initiate low calibration.
105
High calibrate
0 = idle, 1 = high calibration in progress.
Write 1 to initiate a high calibration.
Analogue output
114
Calibration mode
0 = normal, 1 = calibration mode
115
Decrease output level
1 = step down
116
Increase output level
1 = step up
Relays
117
Service mode
0 = normal, 1 = service mode
118
Relay state during service 0 = deenergised, 1 = energised
Remote service in progress
119
Remote service in
progress
0 = inactive, 1 = active
