2102 Press Incr Speed 0…60 Hz Sets the speed for which 20 20 20 20 20
additional pressure is added to
compensate for system frictional
losses at increased flow. Used for
single pump and backup modes
only. Default = 20 Hz.
2103 Press Incr 0….10000 The pressure increase in selected 0 0 0 0 0
units point which is added to the
set point pressure to compensate
for frictional losses at the pressure
increase speed. Used for single
pump and backup modes only.
Note the full set point pressure
increase (%) is achieved at
maximum speed (1401).

22 Control Pump ronous Control Slave Control
2201 Value Decrease 0…1000 Defines how much the actual 5 5 5 5 5
can drop before the next lag
pump is started. Used for
multicontrol, synchronous
control and slave modes only.
2202 Value Increase 0….1000 Defines the increase in set point 5 5 5 5 5
when a lag pump starts. This
value is cumulative with each
lag pump that turns on. Used
for multicontrol, synchronous
control and slave modes only.
The default setting for 2202 is
equal to the value set in 2201.
2203 Enable Sequence 0… 60 Hz Defines the speed the drive 59 59 59 59 59
must be at before multipump
operation is allowed.. Applies to
synchronous, multicontrol and
slave modes only. Default =
98% of 1401 Maximum Speed.
2204 Switch Lead Lag 1…100 h Defines the time the lead unit 48 48 48 48 48
will run before a new unit is
deemed the lead unit. Note if
set to 1001 (Not SEL) the
switching function is disabled
(including switching during a
fault). Default setting is 48 hrs.
