MultiExact Gas Analyser
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.
106
Start auto val
0 = idle, 1 = auto val in progress.
Write 1 to start an auto validation/
calibration.
107
Stop auto val
0 = auto val in progress and can be
stopped, 1 = stop N/A.
Write 1 to stop an auto validation/
calibration.
Pressure
108
Calibrate pressure mode
0 = normal, 1 = calibrate mode
109
Calibrate pressure low
1 = calibrate
110
Calibrate pressure high
1 = calibrate
Flow alarm
111
Calibrate flow mode
0 = normal, 1 = calibrate mode
112
Calibrate zero flow
1 = calibrate at 0% flow
113
Calibrate normal flow
1 = calibrate at 100% flow
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
