1. Summary of Instructions
On delivery, the control relay is set to pre-
programmed standard values.
(see Table 1, pages 15 to 17)
The Reactive Power Control Relay RM
9606 is self-regulating (i.e. it detects and
adjusts to the voltage phase connection,
frequency and the response curent (c/k
ratio) automatically).
Before a reactive power control system
can be put into operation, the target power
factor has to be programmed.
How to programme the Control Relay:
a) The control relay should be connected
as shown in (see page 11).
b) ) Apply voltage to the control relay: "---"
appears on the digital display. The con-
trol relay now identifies the location of
the current and voltage source. This
process takes at least 2 minutes and a
maximum of 15 minutes. The power
factor is displayed. (If this is not the
case, see section 8. page 35).
c) Press the "Set" button for 8 seconds.
"-01-" will appear on the digital display
and the "manual" LED flashes.
d) By repressing the "Set" button the tar-
get power factor is displayed. If neces-
sary, reprogramme to the nearest
higher or lower value by pressing either
the "+" or "-" button until the required
target power factor is displayed.
If no numbers appear on the display
then the control relay must be briefly
disconnected from the voltage
source and the "Set" button has to
be pressed again according to c).
e) To confirm the value press the "Set"
button again. "-02-" will appear on the
display.
f) Now press the "-" button twice until
"END" appears on the display. Store
this value by pressing the "Set" button.
The target power factor is now stored
permanently.
To display the correct values for power
and current, enter the current and voltage
transformer ratios
(see sections 5.16 and 5.17).
To prevent unintentional reprogramming,
the set mode can only be activated within
the first 5 minutes after the operating volt-
age has been applied. If the set mode has
been activated within the first 5 minutes,
you have one hour to complete the pro-
gramming. In order to obtain the set mode
again after this period of time the control
relay must be briefly disconnected from
the voltage source.
On pages 15 - 17 all other preprogrammed
standard values and their programme
ranges are listed. The function of the pre-
programmed standard values is described
under section 5.
