2. A transmitter connected to each drive. (Recommended)
Note – This method Cannot be used on with Flow control.
Notes:
1. Analog Supervision is highly recommended and will require configuration. Refer to Analog input supervision
in this manual.
2. The Multipump functionality uses only the running master’s Process Transmitter’s feedback signal(s).When the
lead is switched or if the Master’s/(Lead’s) Pump/Motor/Drive combination were to fault, the software automat-
ically switches to use all of the connections on the Pump/Motor/Drive combination that it switched the Master/
(Lead) to. This will include the Primary Process Transmitter and any transmitters used for functionality, including
pump protection.
Minimum and Maximum number of pumps.
The PumpSmart PS220 can be set up to operate a minimum number of pumps and also to limit the maximum
number of pumps when required.
The Maximum number of pumps is 6, the Minimum number of pumps is 1.
Example 1:
A Duplex Multipump system where you only run 1 pump. The second Pump is installed as a Back-up or spare.
Min Pumps and Max Pumps would be configured to 1.
Each PS220 will need to be given a start command. If the first pump faulted offline, the 2nd pump would
automatically start.
Example 2:
A Quadplex system that always requires 2 pumps to run constantly, but at times the 3rd and or 4th pump are
needed due to process system demand increases. Min Pumps would be configured to 2 and Max Pumps would
be configured to 4. The first 2 pumps would continuously run after they staged on successfully, but the first 2
pumps to stage will never destage. Only the 2 remaining available pumps would stage and de-stage as neces-
sary. The only way to stop them is to take away the start command.
