4414 DI STATUS
OUTLET
Selects the digital input for connection of a pressure switch
at the pump/fan outlet. The “normal” state is 1 (active). If the
selected input switches to 0 (inactive), the action defined by
is taken after a delay
expires.
NOT SEL
No digital input selected.

is taken on detection of high
outlet pressure.

PROFILE CTL
Parameters
to
provide the Application profile protection
feature, based on long-term monitoring of an internal status
signal. If the selected signal exceeds (and remains above)
the supervision limit for a longer time than the set delay
), the internal status
signal “PROFILE HIGH” is set to 1. The signal can be
directed to a relay output (see parameter group

CONTROL
DEV1
is monitored and compared to
. Monitoring the
deviation between the reference and the actual value gives
an indication of the general condition of the pump, piping
and valves.

DEV2
is monitored and compared to
. Monitoring the
deviation between the reference and the actual value gives
an indication of the general condition of the pump, piping
and valves.
2
is monitored and
compared to parameter
. The
signal constantly remaining at 100% may indicate a leak in
the output piping.
