falls below the upper limit ('Trigger value' +
½ 'Trigger band').
This function is only active when 'Trigger
band' ≠ 0.
Note:
The bottom band limit assumes the
value 0.0 % or 0.0
The top band limit assumes the value
100.0 % or 100.0

3.2.2.3 Triggered by internal sole-
noid valve/forced venting
Triggering by the internal solenoid valve/
forced venting is only active when an inter-
nal solenoid valve/forced venting is installed
in the positioner. See 'Internal solenoid
valve/forced venting' reading (Code 45).
The measured values are included in the trig-
gered data logging when the solenoid valve
is triggered or the forced venting is activat-
ed.
