2) SAFETY NOTE: The front panel of REGO features a series of keys for accessing functions and programming; some functions are activated by pressing a combination of 2 keys: in this manual, when mention is made of a two-key combination (e.g. AUTO/MAN + ), it means that the user must press the first key and, without releasing it, then press the second one. (In fact the combination AUTO/MAN + activates a + AUTO/MAN.

(7) POWERING UP FOR THE FIRST TIME The REGO regulator behaves differently the first time it is started up since it will need the IL parameter (mains C.T.
NOTE: if the incoming current is insufficient (less than 200mA), REGO cannot determine its direction and will stand by in this status until current is supplied. At this point, the controller no longer requires any type of setting and will be ready for perfect operation: it will alternately display “COS” and the system power factor.
DO NOT CHANGE THIS PARAMETER IF THE CONTROLLER IS INSTALLED ON A DUCATI ENERGIA POWER FACTOR CORRECTION SYSTEM. AUt = a new automatic acquisition procedure will be carried out. Press DATA to go on to the next parameter 10.4 “IL” = Mains C.T. ratio. The “IL” parameter is displayed in turn with the value previously set by the user. The value can be changed using the or key. Setting examples: C.T. 300/5 IL =60; C.T. 350/5 IL=70; C.T. 400/5 IL=80 Ex. Press DATA to go on to the next parameter 10.
SEMI-GEOMETRIC LOGIC It is identified by the code 1:2:2 and the power of the first bank must be half that of the others, which must all be equal. The first bank is managed according to a geometric logic whereas all the others, which have equal powers, are managed according to a linear logic.

press or to choose the status of the relay you want to set in the manual operating mode; press the DATA key to display the status of the subsequent relay. After viewing the status of the last relay, press the DATA key to exit this function. 12.2 DISPLAYING THE POWERS OF SINGLE STEPS Press DATA + to access the relevant menu (“CP” will appear on the display and will flash); when the key is pressed, REGO will alternately display “C1” and the value in kVAr associated with the first step. Ex. 12.
13.2 OVERVOLTAGE SIGNAL This signal is activated when the controller measures a supply voltage exceeding the maximum allowed by the transformer (230 +19%; 400 +19%) for longer than 30 seconds. To set the appropriate operating mode for correcting the power factor of generators, press the key: the word “On” will appear. If, on the contrary, you wish to enable the C.T.
After 30 minutes all these actions will be cleared and the controller will automatically resume operation (auto-reset status A.r.), though the incident will continue to be signaled via the display, which will show “A.L.A.” in turn with “t.h.d.” and the measured Crest Factor. To clear the display press ALARM/RESET. This protection is also active in the manual mode. 13.
