22 - MASTER/SLAVE CONTROL
B) Control in parallel with "shifted setpoint":
Machine 1 adjusts itself to the master machine's setpoint. Machine 2's setpoint is shifted by the value of P805. Thus, the machine 2's
setpoint 2 is machine 1's setpoint + P805.
C) Water return control for storage (P154 on master machine = Yes) :
This type of control makes it possible to generate maximum capacity at a given time, often when electricity is cheapest. Both machines
are turned on at an interstage time delay of 10 seconds when P122 + P155 is achieved. The machines are shut off at P122 at an
interstage time delay of 1 second.
- If P154 = Yes, storage control is enabled and the control mode based on the selected setpoint is controlled by the master machine.
Cascade control is used by default for both machines when setpoint 1 selected (standard control).
The 'Yes' value of P154 on the slave machine becomes inaccessible if P28 = Yes.
D) Hourly scheduling :
La programmation horaire de 2 machines en parallèle sera gérée par les paramètres de régulation de la machine maître si P27 = OUI
la programmation horaire de la machine esclave devient inaccessible.
22.1.5 - Machine status menu :
If there are no general faults and the automatic operation inputs are closed, a submenu (overrides the fault message) is added to the
machine status menu :
