Group 22 MULTIPUMP CTRL Description
MODE Selects how multiple PS200 units operate together to satisfy the setpoint.
SYNCHRONOUS [default]
Lag pumps start as needed and all pumps regulate to the setpoint at the same
speed. Note: pumps must be identical.
MULTICONTROL
Lag pump start as needed. The last lag pump to start regulates to the setpoint;
the remaining pumps operate at maximum speed (14.01).
CONSTANT SLV
The master unit starts up to three fixed speed slave units when needed. See RO1,
RO2 and RO3 settings (parameters 19.01, 19.04 and 19.07).
X 22.01
BACKUP
This is similar to single pump control but automatically starts the backup unit if
the primary unit fails. Parameters 22.02, 22.03, 22.04, 22.06, 22.07, and 22.08
are nonfunctional with “Backup”. Note parameters 21.01 through 21.10 are
functional with “Backup”.
X 22.02 VALUE DECREASE
Defines how much the setpoint can drop before the next lag pump is started.
Setting range = 0 – 100% of setpoint. Used for multi-control, synchronous
control and slave modes only. Default = 5%.
X 22.03 VALUE INCREASE
Defines the increase in setpoint when a lag pump starts. This value is cumulative
with each lag pump that turns on. Setting range = 0 – 100% of setpoint. Used
for multi-control, synchronous control and slave modes only. The default setting
for 22.03 is equal to the value set in 22.02. Default = 5%.
X 22.04 ENABLE SEQUENCE
Defines the speed the drive must be at before multi-pump operation is allowed.
Setting range = 0 – 100%. Applies to synchronous, multi-control and slave modes
only. Default = 98% of 14.01 MAXIMUM SPEED.
X 22.05 SWITCH LEAD
Defines the time the lead unit will run before a new unit is deemed the lead unit.
Note if set to zero the switching function is disabled (including switching during a
fault). Setting range 0 – 4000 hrs. Default setting is 48 hrs.
SYNC ENABLE
Selects if Sync Limit (22.07) and Sync Window (22.08) are used to stop the lag
pumps. Used for synchronous only.
NO [default] Disabled
X 22.06
YES Enabled
X 22.07 SYNC LIMIT
Selects the speed at which lag pump #1 should be turned off.
Setting range = 0 – 100% of parameter 14.01 MAXIMUM SPEED. Applies to
synchronous, multi-control, and slave mode. Default is 65% of parameter 14.01
MAXIMUM SPEED for synchronous and 35% for multi-control.
X 22.08 SYNC WINDOW
The speed step above the sync limit (22.07) used to turn off lag pump #2. Twice
the Sync Window is the speed step at which lag pump #3 is turned off. Setting
range = 0 –100% of parameter 14.01 MAXIMUM SPEED. Used for synchronous
and slave modes only. Default is 14% of parameter 14.01 MAXIMUM SPEED.
X 22.09 PUMP ADDRESS
Defines the pump address for multi-pump systems. Address range = 1 –4 where
address 1 is designated as the master.
X 22.10** M/F COMM L DELAY
The time delay before a M/F Comm Loss is declared. Default = 4 sec. This
parameter cannot be changed.
CH2 COM LOS CTRL
Defines the reaction of the drive in the event a fiber-optic communication loss
occurs. Access using pass code 564.
COAST STOP
[default]
Pump stops, coast stop.
RAMP STOP Pump stops, ramp stop.
AUTO CTRL
Pumps operate similar to single pump mode and regulate to set point. Not valid
if using 22.13 TX ONE MASTER.
X 22.11**
LAST SPEED
Pumps run at average speed during last minute of operation. Can be used with
22.13 TX one master setting.
