The foil of the front plate is made of coated plastics. All keys have been designed as touch-sensitive membrane

switch elements. The display is a LC-display, consisting of 2 rows each with 16 characters, which are indirectly il

luminated red. Contrast of the display is infinitely variable by a rotary potentiometer on the left side.

1 Bus CB Free

here: non-functional

Color: green

Enable mains circuit breaker

NOTE: This LED is non-functional, as this control is only designed to oper

ate one circuit breaker.

2 Gen CB Free

Color: green

Enable power circuit breaker

The LED “Gen CB Free” indicates that the power circuit breaker has been

enabled for operation. The status of the LED illuminates when the discrete

input “Enable/Release CB” is energized.

3 Automatic

Color: green

Automatic mode

The LED “automatic” is illuminated when the unit is in automatic mode. It

will turn off as soon as the control unit is switched to the configuration mode.

4 CB close

Color: green

CB close

The “CB close” LED illuminates when the unit outputs a closure command to

the power circuit breaker during synchronization. The “CB close” LED  illu

minates when the relay “command: close CB” is energized.

5 LED-row: too fast

Color: red/yellow/green

Phase position / Synchroscope

The row of LEDs indicates the current phase relationship between the two

voltages indicated in the display. The green LED in the center of the 15 LEDs

indicates that the measured phase angle between the voltage systems is +/-

12 ° electrical. The phase position is only displayed if the controller is in au

tomatic mode and only if the systems U1 and U2 are within the following

limits:

Frequency ranges System U1 96 to 104% fN

System U2 88 to 112% fN

Voltage ranges  System U1 85 to 112% VN

System U2 75 to 115% VN

The synchroscope LEDs can move in two directions:

left  right . If the LEDs illuminate from left to right, the generator (variable

system) frequency is higher than the mains or reference voltage

system (i.e. the generator or the variable system has a frequen

cy of 60.5 Hz and the mains is 60 Hz).

right  left . If the LEDs illuminate from right to left, the generator (variable

system) frequency is lower than the mains or reference voltage

system (i.e. the generator respectively the variable system has a

frequency of 59.5 Hz and the mains is 60 Hz).
