Default setting: 0.1 sec.
Reversing lock for negative controller results
FA23 Reversing lock
Selection 0: Reversing not allowed
Default setting: 0
1: Reversing allowed
Specific pump controller parameter
Specific functions for dual pump booster station control are available in E2000+ inverters. Please ask for
detailed description and configuration proposals
Master / Slave interchange
FA24 Interchange time: units
Selection: 0: hours
Default setting: 0
1: minutes
FA25 Interchange time setting (hours / min.) 1....9999 Default setting: 100 h
Idling / lack of water protection
FA26 Lack of water protection
Selection: 0: No protection
1: Sensor signal through digital input
Default setting: 0
concept 2: Controller algorithm
3: Motor idling current detection
FA27 Current limit for lack of water
Range: 10…150 %
Default setting: 80%
detection (% of rated current)
FA28 Recheck delay time (sec.)
Range 0.0…3000 sec.
Default: 60 sec.
FA66 Delay time for lack of water
Range: 0…60 sec.
Default setting: 2 sec.
message (FA26=3)
FA26=1: Lack of water is triggered through digital input (function assignation code 30 )
– it will stop the inverter and
display EP1
. The „Water OK“ signal through a different digital input (function assignation code
31 ) will reset the system.
FA26=1: there is no delay for fault trigger.
FA26=2: In case the controller reaches the maximum frequency, and the motor current still remains below the value
in FA27, the controller will interpret the situation as lack of water. EP2 will show up on the display. The inverter will
stop immediately.
FA26=3: Detection via motor current measuring only. If the motor current falls below the value in FA66, the fault will be
triggered with delay, set in FA66. Inverter will stop and EP3 will show up on the display.
FA28 Recheck time, timeframe for the inverter to recheck, if lack of water condition still persists, before it restarts. It is anytime
possible to reset the system, pressing.
Controller dead band +/- % of the set point
FA29 Dead band setting (% of set-point) Range: 0.0 - 10.0 % Default setting: 2.0
If the feed -back (actual value) stays within the dead band, the controller does not make any activity, and it keeps the
output frequency constant. The FA29 parameter is used also for starting/stopping the fixed speed pump
– see below
Dual pump booster control (one pump inverter controlled, one pump fixed speed)
FA30 Delay-time to start inverter pump (sec.) Range: 2.0 - 999.9 sec. Default setting: 20.0
FA31 Delay-time, to start fixed speed pump (sec.) Range: 0.1 - 999.9 sec. Default setting: 30.0
FA32 Delay-time to stop fixed speed pump (sec.) Range: 0.1 - 999.9 sec. Default setting: 30.0
If the feed- back value (actual value) exceeds the limits, given by FA29, the fixed pump will be started or respectively
stopped. Start /Stop delay time is set by
FA31 and FA32.
