Default setting Description
No (empty)
Limit value above and below the setpoint
value
As for AF1, output signal inverted
Limit value below the setpoint value
As for AF3, output signal inverted
Limit value above the setpoint value
As for AF5, output signal inverted
Fixed limit value independent of the set-
point value
As for AF7, output signal inverted
No selection Analog value as actual value (signal to be
monitored)
No selection Analog signal as setpoint value (refer-
ence signal for AF1 to AF6)
0 Admissible deviation (AL) of the actual
value
Symmetrically Standard of monitoring band for AF1 and
AF2
Standard monitoring band, formed by the
limit value (AL)
Non-standard monitoring band, formed
by the limit value (AL) and limit value 2
(AL2)
Symmetrically Switching differential position around the
limit value
Switching differential is positioned with
half above and half below the limit value
Switching differential is below the limit
value (typically)
Switching differential is above the limit
value (typically)
Off Alarm suppression during
start-up phase
Limit value monitoring function always
operates according to its alarm function
Alarm suppression after power on or if
limit value or setpoint value is changed
0 Delay time (in seconds) for activation of
the output signal if alarm condition is
present
0 Delay time (in seconds) for deactivation
of the output signal if alarm condition is no
longer present
