Drift alert
mode
Definition of the behavior if measured values for sensors 1 and 2 deviate from one
another.
Input:
• off
•Warning
•Alarm
Warning:
The 'Caution' icon becomes active on the display. A warning is transmitted via the
HART
®
protocol.
Alarm:
The 'Caution' icon becomes active on the display. The device switches to error
signal.
++V2H0
Drift mode Drift. No input necessary if the drift alert mode = off.
Input:
• Larger
Alarm/warning if absolute amount for difference between sensor 1 - sensor 2
overshoots a defined limit value (see drift alert value). Larger is the standard
value for device versions < SW 01.03.00 in which the parameter is not available.
• Smaller
Alarm/warning if absolute amount for difference between sensor 1 - sensor 2
undershoots a defined limit value (see drift alert value).
≥ SW 01.03.00 ≥ SW 01.03.00 -
Drift alert
value
No input necessary if the drift alert mode = off.
Input of the limit value for the drift alert or warning. Depending on the 'Drift mode'
function, the drift alert or warning is active in the event of overshoot or
undershoot.
Input: 0 to 999
1830.2 °F (999 °C)
++V2H1
Fault
condition
Input of the output signal on sensor rupture or short circuit.
Input:
• max (≥ 21.0 mA)
•min (≤ 3.6 mA)
++V1H8
Error current
specification
Input only possible if fault condition = max
Input: 21.6 to 23 mA
21.7 mA
≥ SW 01.03.00 ≥ SW 01.03.00 -
Alarm
hysteresis
Transient alarms are suppressed at the analog output (e.g. caused by electrostatic
discharge).
Input:
• 0 s
•2 s
•5 s
!
Note!
In the time entered, the last measured value before the alarm is output. If the error
is still present after this period, an alarm is signalled.
