P.01 for CT primary current can remain set to OFF while all the others can be
programmed.
In this case during the system installation and once the controller is powered up, the
display will view a flashing Ct (Current Transformer). The CT primary can be set directly
by pressing + and -.
Once programmed, press MAN/AUT to confirm. The unit will store the setting and directly
restart in automatic mode.

1.11 AUTOMATIC SET-UP

The setting is useful if it is not possible to access the C.T. or else when the characteristics
The automatic set-up of parameters allows the unit to be placed in service without having
to program any parameter.
To activate the automatic set-up when the unit is in MAN or --- mode, simultaneously
press MODE and MAN/AUT keys for 5 seconds.
The wording ASE (Automatic Set-up) flashes indicating that the automatic set-up of the
parameters is in progress.
The procedure will last a few minutes during which the controller measures the power
rating of the connected steps. This measurement will then be continuously updated during
the normal operation.
If the load of the system varies frequently, the same step may have to be measured
several times. In this case, the procedure may last longer.
At the end of the automatic set-up, the controller is ready for automatic operation.
It is recommended to avoid substantial current variations as much as possible during the
automatic set-up. During this automatic set-up, the controller is not able to monitor certain
data such as CT primary current, rated capacitor voltage.
Therefore we shall have as follows:
The current cannot be viewed in Amperes but only as a percentage.
The kvar and kvar measurements are not available.
The measurement and protection for capacitor overload are not accessible.
All of the relays are considered as normal capacitors banks. So no alarm relay or fan
control configuration is possible.
The capacitors installed must be with a power rating which is a multiple of 1, 2, 4, 8 or
16 times the smallest capacitor step.
The unused steps must be placed at the higher step numbers.
Note: After termination of the automatic set-up, if access is gained in manual mode to
setting the parameters, the controller will consider all the parameters present as valid.
Therefore, all of the measurements and functions will be available once again.
Never use if a complete panel has been purchased.
of the capacitor banks are not known.
