Alarm mode
Al: abs Absolute alarm. The programmed alarm has a fixed reference to
the scaling range.
Al: rel Relative alarm. The programmed alarm has a fixed reference to
the setpoint.
Alarm limit
PV+: High alarm limit
Adjustment range:
Pv-
≤ PV+ ≤ PVh
PV-: Low alarm limit
Adjustment range:
PVl
≤ PV- ≤ PV+
Hy: Alarm hysteresis
Adjustment range:
0.1 ≤ Hy ≤ 20.0 (in %, related to the
scaling rangePVl, PVh, or, if these can not
be set, to the size of the measuring range.
Filter 1
An interference signal superimposed on the measured signal can be attenuated with
the filter. The filter consists of a low pass filter of the 1st order.
Fg1: Limiting frequency (-3 dB) of input filter 1
Adjustment range:
0.1
≤ Fg1 ≤ 20.0 (in Hz)
0.1 Hz: strong damping (time constant = 1.6 sec)
20 Hz: weak damping (time constant = 0.01 sec)
