Functions &
Features
The table below lists all of the Parameters used in this function:
GROUP 60 MULTIPUMP COMMUICATION
SETUP
DESCRIPTION
60.02 PUMP ADDRESS
Selects the node address of the drive for Multipump D2D Master and D2D Follower
communication. No two nodes may have the same address. Range is 1 – 6.
GROUP 81 MULTIPUMP DESCRIPTION
81.01
MODE
Selects how multiple PS220 units operate together in parallel to satisfy the set-point.
Multipump control is disabled. (Default)
Synchronous Speed.
Lag pumps start as needed and all pumps regulate to the set-point at the same speed
or torque.
81.02 VALUE DECREASE Defines the percentage difference decrease between the system set point versus the
actual value to initiate staging of an available lag pump. Setting range = 0.0 – 100.0% of
set point.
81.03 VALUE INCREASE Defines the increase in the systems set point desired when lag pumps start. This value is
cumulative for each additional lag pump that stages on. This is used to compensate for
higher friction losses form increased flow rate in systems that need to be overcome as
additional pumps add more flow into the system.
The formula used is Set point Increase = Value Decrease - Value Increase
Setting range = 0.0 – 100.0% of set point. The default setting for is equal to the value set in
81.02. (No increase in setpoint as additional pumps stage on)
The setpoint will decrease at the same rate as pumps destage.
81.04
STAGE/DESTAGE METHOD
Selects the method of staging or de-staging pumps in the MultiPump system.
Pumps stage and de-stage based on speed or Torque. Default)
Pumps stage and de-stage based on the process variable values.
81.09 STAGE 2 Selects the control value at which lag pump 1 should be turned on. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.10 STAGE 3 Selects the control value at which lag pump 2 should be turned on. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.11 STAGE 4 Selects the control value at which lag pump 3 should be turned on. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.13 DESTAGE 2 Selects the control value at which lag pump 1 should be turned off. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.14 DESTAGE 3 Selects the control value at which lag pump 2 should be turned off. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.15 DESTAGE 4 Selects the control value at which lag pump 3 should be turned off. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.17 STAGE 5
Selects the control value at which lag pump 5 should be turned on. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.18 STAGE 6 Selects the control value at which lag pump 6 should be turned on. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.21 DESTAGE 5 Selects the control value at which lag pump 4 should be turned off. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.22 DESTAGE 6 Selects the control value at which lag pump 6 should be turned off. Setting range = 0.0 –
100.0% of MAXIMUM SPEED/Torque or the actual Process variable.
81.23 MULTIPUMP RUNTIME RESET Selecting Reset clears the operating hours accumulated on this drive only when running in
MultiPump operation.
81.31 SWITCH LEAD TIME Defines the elapsed actual motor runtime time the D2D Master (Lead) will run before
switching to the next available D2D Follower (lag) in the system. 0.00 hours disables the
function, including alternating when a fault may occur. For the equivalent of disabling
the alternating function and allowing for alternation during a fault, set the value to
99999.00 Setting range is .01 to 99999.00 hours. Maximum hours =11.5 years.
81.32 SWITCH LEAD Allows for the manual switching of the D2D Master (Lead) via this parameter. Selections
are: Disabled (default), pump 1, pump 2, pump 3, pump 4, pump 5 and pump 6. This
parameter returns to disabled after a selection is made. Manual switch shall function only
through the D2D Master using the D2D Master’s keypad, or PC tool.
81.33 MAX PUMPS ON Defines the maximum number of pumps that can stage on, and then continue to run as
required.
81.34 MIN PUMPS ON Defines minimum number of pumps that can run at any one time or when de-staging has
been completed. De-staging is ignored on any pump less than this number.
81.36 SWITCH LEAD SLP COUNT Defines the elapsed number of times the D2D Master (Lead) pump goes into sleep mode.
After this count the D2D Master (Lead) will be automatically transferred to the next
available D2D Follower (Lag) in the sequence. Any value greater than 0 automatically sets
parameter 81.31 to 0 disabling switching based on hours.
81.38 DESTAGE PROOF TIME Elapsed time required before the de-staging of a lag pump will occur. De- stage value
and the reference value must both be met during this timeframe. Setting range 0-900
seconds. Default is 20 seconds.
81.39 STAGE PROOF TIME Elapsed time required for the staging of a lag pump will occur. The stage value and the
value decrease value must both be met during this timeframe. Setting range 0-900 seconds.
Default is 20 seconds
81.41 Follower Switch Factor This allows for the automatic balancing of D2D Follower (lag) pumps if used on a system
with significantly unequal run times. It will use this number as a multiplier of the switch hours
to offset the unequal time differences to eventually equal them out over time. The default is
0
