• The operating mode remains in memory even after the supply voltage is disconnected.

MAN mode

This mode is used to select and connect/disconnect all live steps.

• Press to connect/disconnect the step.

• Because of the capacitor discharge time, the controller does not allow the same step to be reconnected for at least 3 minutes after being disconnected.

• If the step number

are ashing, the operation has been taken into account, but the controller waits for the time required before

reconnecting the step.

• The step conguration is maintained even when the supply voltage is disconnected. When the power returns, the initial status is restored.

AUT mode

This mode allows the controller to calculate the optimum step conguration in order to obtain the setpoint cos phi.

• The selection criteria take account of numerous variables such as: each step’s power rating, the number of operations, the total operating time, the

reconnection time, etc.

• The controller warns of imminent connection/disconnection of the step by displaying the ashing step number. Flashing may continue if the step

connection is not possible immediately due to the programmed reconnection time.

• The controller activates the steps when the reactive energy demand (delta-kVAr) is greater than 50% of the power rating of the smallest step and the cos

phi diers from the setpoint cos phi.
