Function Switch (3)
(Standard Version with 10 Switch Positions)
0 = Relay not in automatic function. All steps will be switched off after 20 secs. The digital display will show "OFF".
1 = Adjustment of pre-set target power factor within the range 0,70 lag ...1,0 ... 0,90 lead. by means of the +/- buttons. Target level is shown
in the display.
2 = Adjustment of the step switching time, 5 secs ... 1200 secs, by means of the +/- buttons. For rapid digit change, hold the button down
continuously. The display will show for example "50".
3 = Relay in automatic function, with indication of system power factor in the digital display, i - ind., c = cap. If the +/- segments are
flashing, this indicates that the target power factor has not been achieved. A suitable capacitor size will be selected.
4 = Manual operation. The display will show alternately "H" (1sec) and Power Factor (5 secs). Capacitor steps can be switched in rotation
after the selected step switch time, using the +/- buttons.
5 = The number of switching steps can be limited, using +/- buttons. The display will indicate the number of steps - e.g. for 10 steps "CL10".
Do not exceed the number of steps on the relay!
6 = Automatic indication in the display of the number of steps which are not connected or are not working. The indication will rotate through
the non-functioning steps, e.g. "Cd 5" = 5 non-functioning step. Display "Cd 0" means that all steps are functioning. Automatic regulation is
active during this time (CD = capacitor defective)!
Any failed capacitor step will be displayed with letters “AL” alternating with cos phi indication.
The indication of defective steps can be cancelled by pressing the +/- buttons together for a period > 20 secs. Automatic regulation is active
during this time!
7 = The number of switching each contactor has made is shown in the display, e.g. "OC 4" for 2 secs., then "248". This indicates that
contactor no. 4 has completed 248 switchings. Other contactors can be selected using the +/- buttons. Only every 50 switchings, the
microprocessor stores the data. The stored data of all steps can be cancelled by depressing the +/- buttons together, for a period of > 20 secs.
Automatic regulation is active during this time!
8 = Indicates the measured "unit of value" of each step, which is proportional to the capacitor output in kVAr. For example, the display will
show "CC 12" for 2 secs., to indicate step No. 12., and will then alternate to "125" units of value. Once the value falls below a level of < "8",
the capacitor will be excluded from the regulation process. The "unit of value" for other steps is obtained by depressing the + or- buttons to
select the required steps. The stored data of all steps can be cancelled by depressing +/- buttons together for a period > 20 secs. This starts a
redefinition of the capacitor outputs. Automatic regulation is active during this time! (CC=Capacitor capacity)
9 = Selects the mode of alarm signal required. If the display shows "A 0", the alarm is stored in the memory and can only be cancelled by
briefly switching DIP switch (S2) off. If the display shows "A 1", the alarm will be cancelled automatically, when the target power factor
level is restored (Selection by means of +/- buttons). Any reset at option “L” will be
triggered after a passed ”time window” of 8 minutes
only.
If requested data are not indicated on order, the relay will be shipped in "A 1" mode!
B = Input for assymetrical switching times. Using the +/- buttons, this can be adjusted between 0 ... 50. For example, if the display shows
"Y" 10" the factor displayed will multiply the switching off time in the capacitive direction. (Rapid switching on - slow switch off). The
standard setting with equal switch on/off times is "Y 0".
C
= Rapid contactor switching rate limiter. By using the +/- buttons a time delay can be set in seconds so as, to prevent the rapid on/off
switching of a contactor on a constantly changing load. The standard setting would be 30 secs. and the display would then show "L 30". The
delay time can be set up to 255 secs.
D = no function
E = OFF. Same effect as function switch in Position 0 (see above).
F = Indication of Switching mode
"S CC" = Economy Switching (Connected capacitors have different sizes)
" CC" = Circular Switching (Connected capacitors have equal sizes)
