10.8 Parallel Pump Instructions
10.8.1Twin Pump Function: The VR Series Parallel Pump Function enables the communication between two pumps
when piped in parallel, without the use of additional control devices. Parallel pump control requires both pumps
connected via a CROSSOVER Ethernet cable. The installation of a check valve is required on the discharge side of
each pump, installed at least 10 pipe diameters from the pump discharge. Failure to install check valves will cause
reverse ow through the o pump and may damage the electronics and cause lower than required system ow.
1.1 Automatic Alternation: To ensure equal run times the pumps are alternated every 24 run time hours.
The alternation hour period is not adjustable.
1.2 Back-up Operation: If the operating pump experiences an overload condition
(See Section 19) an enable (run) signal is sent to the back-up pump. The back-up will
remain active until the cause of the overload is corrected.
1.3 Cascade Operation: If the ow demand exceeds the maximum ow of the operating pump a
run signal is sent to enable the o pump, running both pumps at the same time. The pump
system returns to single pump operation as the ow demand drops. It is IMPORTANT both pumps
are the same model and have the same settings and are NOT set on activeADAPT mode.
