6.7 The function of the booster set
A booster set consists of two GENYO plus units connected to two identical pump units,
referred to as master and slave.
The units protect the pump units operating in cascade mode and with alternating start
sequence. If the pressure decreases, the master unit starts first.
For setting a booster set:
1. Insert the pressure values of the master and slave pump units:
• P1 START = P2 START
• P1 STOP = P2 STOP.
Note: the difference between P START and P STOP must be ≥ 0.1 MPa / 1 bar (14.5 psi).
Minimum P START = pressure of the parameter 5.1 + 0.5 bar (7.3 psi).
2. Enter the parameter menu, see

Note: parameters 5.1 and 7 must be the same for the master and slave pump units.
5. Exit the parameter menu.
6. Check that the pressure is at zero.
7. Set AUT mode to start the pump units and calibration of the system (10 cycles).
8. The alarms A01 and A11 could be triggered during this phase: press the MENU/ENTER
button (6) to reset them.
