After 30 minutes all these actions will be cleared and the controller

will automatically resume operation (auto-reset status ),

though the incident will continue to be signaled via the display,

which will show “ ” in turn with “t.h.d.” and the measured

Crest Factor.

To clear the display press .

This protection is also active in the manual mode.

This protection trips in the presence of mains voltage dips lasting

more than two periods (40mS at 50Hz, 33mS at 60Hz). In such

cases, also in the manual mode, the controller will instantly

all the output relays in order to protect the capacitors. It

will then resume its normal control functions, switching steps into

service as necessary after the time T1 has elapsed.

If the voltage dip lasts longer than two cycles, or the voltage drops

below the minimum required to power the device correctly, the

“powerfail” cycle will be activated: REGO will instantly de-

energize all the output relays until the voltage returns to normal

levels or disappears completely to prevent undesired operations

on the capacitor banks.

The user can see how many times the controller has gone into an

alarm status due to overvoltage & excessive harmonic distortion.

To view the counters, press + . The letters “ ” will

appear and the LED will flash.

Ex.

Press the corresponding key to access the settings. The s and

LEDs will flash and the first alarm ( ) will be displayed in

turn with the number of activations; to view the next alarm ( )

press the key. Press the key again to exit the

function.

These counters cannot be cleared.

The user can change the activation modes of the controller

alarms. In particular, as regards the signals and protections for

power factor correction failures, overvoltage, overtemperature

and excessive harmonic distortion, it is possible to set:

status: this has the functions described previously, except

that the auto-reset ( ) function will not be active and the

controller will remain in a standby status until you press the

key on the front panel. Pressing this key will

enable the controller to resume normal operation.

status: the protection and alarm or signaling function and

all their consequent actions are completely inhibited. The

user should be fully aware of the risks of choosing the

status; as a rule it is an choice, since it may give

rise to potentially hazardous situations.

the letters “ ” will appear and the LED will flash.

Press the corresponding key to access the settings. The s and

LEDs will flash and the first alarm/signal will be displayed; to

change the alarm status press the + key and to go on to the

next alarm press the key (° ); after the last

parameter has been displayed, press the key again to exit

the function.

To access the menu, press + and while the “ ” parameter is

shown on the display, keep the keys

pressed down until the display shows:

At this point you have entered the hidden menu. All the

parameter sequence is asfollows:

– (“ ”) for closing the N/O relay that

modify).

– (“ ”) Display of

parameter).

– (“ ”) Setting of the . If the

controller is powered via a VT (refer to chapter 10.3 - “UFF”

rather than changing HU.

– (“ ”) Setting of

The possible settings are 1,2,3. If you set 1, the trip time will be

proportional to the level of harmonic distortion; setting 2 will

double this time; setting 3 will quadruplicate the time (you are

advised not to change this parameter).

9600bps is shown as “960”; this parameter is available only for

seven- and twelve-step versions of REGO).
