Pro Series
Introduction
The Trifecta Pro control system allows for multiple units to
communicate if connected via common Ethernet network
When connected, one Trifecta is configured as the Master
Trifecta, while up to four other units are configured as Slave
Trifectas The Trifecta units will cycle between Active and
Standby in order to share the workload. When needed,
the Master Trifecta can call upon the Standby units for
assistance
The Master will control which Trifectas are at the Active
and which are at Standby The pressures which Active and
Standby units run at are controlled by the Master Trifecta
Standby units will run at a preset pressure below the PB On
setpoint of the Master Trifecta The Master will rotate which
Trifectas are Active and which are Standby based on an
adjustable amount of time
The Master Trifecta will make any Standby Trifectas
Active if any of the Active units request assistance or loses
communications with a Slave Trifecta If any Slave units lose
communication with the Master, it will run as a standalone
Trifecta, using its own pressure on setpoint.
If an Active unit requests assistance, all Standbys will remain
active for a minimum of 30 minutes The Previous Cycle
Timer must be greater than the preset amount of time based
on flow capacity of the Trifectas in order to release the
Standby units back to Standby
HMI Screens
The following screenshots describe changes to existing
screens and screens which were added for when running in
parallel with other Trifectas
MAIN Screen - Master/Slave

It also indicates if the unit is Active, Standby or has lost
communications
• S: Active — Slave Trifecta with PB on set to the Active
Pressure
• S: Standby — Slave Trifecta with PB on set to the
Standby Pressure
• S: Loss of Comm — Slave Trifecta which has lost
communications with the Master Will run using PB On
Setpoint set locally until communications are restored
• M: Active — Master Trifecta with PB on set to the
Active Pressure
• M: Standby — Master Trifecta with PB on set to the
Standby Pressure
• M: Loss of Comm — Master Trifecta has lost
communications with the one or more Slave units Will
run using Active PB On until communication is restored
SETPOINT DATA ENTRY Popup - Master/Slave
Pressure Build (PB) On field
• Master — Displays the PB On setpoint to be used by all
Active Trifectas
• Slave — Displays the PB On setpoint to be used upon
loss of communications with the Master Trifecta
