Press Set button until “ Manuel” led is on.
Using up and down buttons, you can adjust manual mode “
001
” or “
000
” on the display for automatic operation.
Pr e s s S e t bu
tton again, manual / automatic selection will be stored in the memory and relay will start functioning.
At manual mode, “
M a n u e l
” led starts blinking that means manual operation is on.
At manual mode, you can connect the capacitor steps using up button and disconnect the capacitor steps using
down button.
In order to connect one step, press up button for a while and “
C+
” led’ will be on, according to the adjusted “
T
on
” , the desired step
will start to operate properly. In order to connect an additional step, same operation is repeated.
In the same logic, in order to disconnect a set, pres down button for a while and “
C –
“ led will be on, after the adjusted “
T
off
”, the
step will be disconnected.
SIGNALS
On the top of the front panel, there are equal number of leds to the number of steps. Therefore, it’s easy to follow which steps are
connected. The functionn of the other leds are as follows:
“
C +
“ led is on means the system need capacitors and after Ton period, the following capacitor step will be connected
“
C –
“ led is on means the system is over compensated and at the end of Toff period, the proper capacitor step will be disconnected
“
N o r m a l
” led is on means the system is well compensated.
“
C a p .
” led is on means the load is capacitive
“
nd.
İ
” led is on means the load is inductive
“
C o s ø
” led is on displaying the present cosø (power factor)
“
Q/P (%)”
led is on displaying the present ratio of reactive power to active power
For example, the display reading “0,25” and “
in d
” led’ is on, it means the present ratio of reactive power to active power is 25%.. In
similar manner, the display reading “0.10” and “
C a p .
” Led’ is on, it means the present ratio of reactive to active power is capacitive
10%
In order to read “
Q/P (%)
” press any up or down button for a while. (Relay should be in automatic mode)
At normal display, the screen will show
pr e s e n t co s ø
. In order to read the ratio of reactive power to active power, press any up or
down button for a while and the display will read
Q/P(%)
for about 10 seconds. After 10 seconds
co s ø
value will be displayed
automatically. In order to return reading
co s ø
, pres any up or down button for while
SWITCHING
The switching logic of the relay depends on the selectedsequence type, either rotating systems or double rotating system. In this
logic, the capacitor steps will be switched equally for long periods .
1.1.1.............1 system rotating system
1.2.2.............2 system rotating system.
1.2.3.3 .........3 system double rotating systems
1.2.4.4..........4 system double rotating system
1.2.3.6..........6 system double rotating system
1.2.4.8.8.......8 system double rotating system
Let’s explain a double rotating system.
For example 1.2.3.6..........6 system is selected . In this case the first 3 steps 1.2.3 are rotating internally and the other steps are
rotating internally. Ton is adjustable between 1 and 250 seconds and Toff is adjustable between 1 and 100 seconds.
