When the PFC is programmed to operate with two setpoint ranges, the active setpoint

range is selected by the external contact status through the instrument's digital input:
open = SP1, closed = SP2 setpoint range. To sense an external contact status, the
digital input should be configured as a status input (see Section 4.3).

Nominal voltage is shown in units of Volts as a whole number, or in kVolts with two

decimal places.

These parameters appear only if setpoint SP2 is selected as an operational setpoint.

Setting this parameter to 'On' forces a capacitor bank to be permanently switched in

when the PFC is put into an operation mode, and to be switched out when the PFC
shuts down, following all switching and re-close time delays. The permanently switched
banks continue under PFC protection but are not involved into either switching program.

This delay is also used in automatic operation modes as the reference restoration time

when an alarm setpoint override condition takes place followed by the soft release of
the capacitor banks (see Section 4.6). When the alarm condition is no longer present,
the PFC will delay restoration of the automatic switching program for an amount of time
equal to 50 times the power factor setpoint operate delay. This prevents excess cycling
in over-voltage and high harmonics conditions.

NOTES:

1. The PFC setup parameters, except the operation mode, are protected from being

changed while the PFC is running. Ensure that the PFC is OFF before configuring setup
parameters. To disable protection after shutting the PFC down, exit the setup menu,
and then re-enter the menu once more.

2. The PFC may not be put in operation mode if no capacitor banks are specified in the

PFC setup either as controlled or permanently switched banks.

3. The power rating values for the capacitor banks are not allowed to be in descending

order. Each capacitor bank must have the same or higher power value than the
previous bank. When entering the bank powers, the starting value is prompted at equal
to the power of the previous bank and is not permitted to drop below this value.
