2.3. Duplex Control: 2 variable speed pumps each with its own controller
• PRESSURE CONTROL UNITS: Select the appropriate control units for the
application (psi, bar, etc.)
• RAMP TIME: The Ramp Time is the time to transition from stop to full speed.
• Fast = 5s accelerate and 3s decelerate.
• Medium = 10s accelerate and 5s decelerate.
• Slow = 20s accelerate and 10s decelerate.
• DUTY STANDBY: Duty Standby, if enabled, prevents both pumps from
running at the same time. (The second pump acts as back-up.)
• LAG PUMP START FREQUENCY: This parameter defines the speed which
the lead pump needs to achieve before the lag pump will be started. Setting
Start and Stop frequencies too close together will cause frequent starts and
stops of the lag pump.
• LAG PUMP STOP FREQUENCY: This parameter defines the speed to which
system needs to drop before stopping the lag pump. Setting Start and Stop
frequencies too close together will cause frequent starts and stops of the
lag pump.
• ALTERNATION: When enabled, this parameter will alternate the lead pump
after the elapsed time specified in Alternate Time.
• ALTERNATION TIME: Time setting for the amount of elapsed time (not run
time) between lead pump alternations.
• PUMP EXERCISE TIME: If enabled, and there is no demand at alternation,
Pump Exercise will force lead pump to run at the minimum speed for the
time defined by this parameter. (0=Off/Disabled Pump Exercise.)
• START DELAY: This parameter enables a delay of the starting time.
Set the start delay time until acceleration is to begin.
