press or to choose the status of the relay you want to set in

the manual operating mode; press the key to display the

status of the subsequent relay. After viewing the status of the last

relay, press the key to exit this function.

Press to access the relevant menu (“ ” will appear

on the display and will flash);

when the key is pressed, REGO will alternately display “ ”

and the value in kVAr associated with the first step.

Ex.

Every time you press the key, the controller will show the

powers of the individual steps in sequence; after viewing the last

step press the key to exit this function.

Press to access the menu pertaining to the procedure

for checking the powers of the capacitor steps (the display will

show “ ” and will flash).

Pressing the key will cause REGO to switch off all the banks

and start the procedure for measuring the power of all the steps

(the cycle will be launched three times to provide a better

measurement). If REGO detects differences of more than 25% in

the power that was associated with the step during the previous

auto-acquisition procedure, the corresponding LED will flash. At

the same time the letters “ ” will appear on the display

and the user must disable the step by pressing ; if

this key is not pressed within a few seconds, the operation will be

terminated without any effect taking place. Once the check is

completed, REGO will function as before, with the exclusion of

any steps detected to be faulty, whose LEDs will continue flashing

to signal their status of unavailability.

The user can decide which relays the controller must not use in

the automatic mode.

Press + to access the menu for enabling/disabling

the output relays (the display will show “ ” and will flash).

When you press the key, the + LEDs will flash and the

display will start showing the status of the first relay: “ ” will be

displayed in turn with its status (“ ” or “ ”).

Ex.

At this point you can choose the status of the relay, pressing the

key to switch it “ ” or the key to switch it “ ”. Press the

key to display the status of the next relay; after viewing the

status of the last relay, press the key to exit this function.

The user can display the number of switching operations

performed by each relay controlling the capacitor banks.

Press + to access the relevant menu (the display

will show “ and will flash).

When you press the key, the + LEDs will flash and the

display will show the operation performed by the first output relay.

“ ” will appear, followed by the number of switching operations.

A“ ” is used to separate thousands.

Ex.

Press the key to display the number of switching

operations of the next relay; after viewing the data of the last

relay, press the key to exit the function.

when an output relay counter totals over 100,000

switching operations, the LED corresponding to the step will flash

to warn of the need to overhaul/replace the contactors. The

output will not be disabled, only a warning will be signaled.

To display the software release number of the controller, press

: the display will alternately show “Flr”

and the firmware version “x.xx”.

An automatic procedure is provided to make it easier to check the

efficiency of connections to the capacitor steps, independently of

the mains network status and the presence of current on

terminals “ ” ed “L”. This procedure can be launched by pressing

DATA + AUTO/MAN regardless of the current controller situation

(“ ” will appear on the display and the LED will

flash);

if the procedure is launched during normal operation, it will be

necessary to press the key for about another 2

seconds to confirm the launching of the test. The procedure

consists in switching on the individual steps in sequence at two-

second intervals. The closing time of an individual step is five

seconds.

To correct the power factor of the generators, the user must set

this operating mode, which involves inhibiting the automatic

mains CT direction adjustment function and configuring the

signals accordingly.

This operation must be carried out with the mains powered by the

generator.

Press + to access the menu for fixing the C.T.

direction. When you press the keys, the LED will flash and

you must press the corresponding key. At this point the and

LEDs will flash and the controller will simultaneously display

“ ” (INV) in turn with “ ” or “ ”.
