The conditions for starting a trigger event
are met when the value exceeds the lower
limit ('Trigger value' – ½ 'Trigger band') or
falls below the upper limit ('Trigger value' +
½ 'Trigger band').
This function is only active when 'Trigger
band' ≠ 0.
The bottom band limit assumes the value

at the lowest. The top band
limit assumes the value 100.0% or 100.0

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.
