Actual signals and parameters 249
4414
DI STATUS OUTLET
NOT SEL
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 parameter
4409 OUTLET PROT CTRL is taken after a delay set by
parameter 4415 OUTLET CTRL DLY expires.
0 = NOT SEL – No digital input selected.
1 = DI1 – Pump/fan outlet pressure monitored through digital input DI1.
2 = DI2 – See selection DI1.
3 = DI3 – See selection DI1.
4 = DI4 – See selection DI1.
5 = DI5 – See selection DI1.
4415 OUTLET CTRL DLY 0.1 … 3600.0 s 1 = 0.1 s 60.0 s
Sets the delay after which the action defined by parameter 4409 OUTLET PROT CTRL
is taken on detection of high outlet pressure.
4416
OUTLET FORCED
REF
-100.0 … 100.0% 1 = 0.01% 0.0%
This reference is used after detection of high outlet pressure. See parameter 4409
OUTLET PROT CTRL .
WARNING! Make sure that it is safe to continue operation using this reference.
4417 PID OUT DEC TIME 0.0 … 3800.0 s 1 = 0.1 s 60.0 s
PI controller ramp-down time. See selection PROTECT for parameters 4401 INLET
PROT CTRL and 4409 OUTLET PROT CTRL .
4418 APPL PROFILE CTL NOT SEL
This parameter and parameters 4419 PROFILE OUTP LIM and 4420 PROF LIMIT ON
DLY 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 (parameter
4420 PROF LIMIT ON
DLY ), the internal status signal “PROFILE HIGH” is set to 1. The signal can be directed
to a relay output (see parameter Group 14: Relay outputs ).
0 = NOT SEL – Not selected.
1 = CONTROL DEV1 – Signal
0126 PID 1 OUTPUT is monitored and compared to
parameter 4419 PROFILE OUTP LIM . Monitoring the deviation between the
reference and the actual value gives an indication of the general condition of the
pump, piping and valves.
2 = CONTROL DEV2 – Signal 0127 PID 2 OUTPUT is monitored and compared to
parameter 4419 PROFILE OUTP LIM . Monitoring the deviation between the
reference and the actual value gives an indication of the general condition of the
pump, piping and valves.
3 = APPL OUTPUT – Signal 0116 APPL BLK OUTPUT is monitored and compared to
parameter 4419 PROFILE OUTP LIM . The signal constantly remaining at 100%
may indicate a leak in the output piping.
4419 PROFILE OUTP LIM -500.0 … 500.0% 1 = 0.1% 100.0%
Supervision limit for the Application profile protection. See also description in
parameter
4418 APPL PROFILE CTL .
