I i24
(step 4 as circular sequence)

In case a compensation demand for the reactive power value (K Var) is 10 times of the CK
value, the following explanations are as follows :
In order to replace the gradual switching on/off capacitor step, there are two
solutions to an extended life of both the contactors and the capacitors as follows.
1. Switching on/off the largest possible capacitor step is in order to reduce the
frequent switching operations. And the switching program will directly start
entering the step in circular sequence for switching on/off capacitor if the actual
load is fitted in with the circular sequence. Furthermore, the rest of the switching
program should be activated in compliance with the selected mode.
A
2. After starting this procedure, in case of the subsequent connection/ disconnection
to capacitor again, a half of the preset switching delay time under the
LY
model
will be activated; meanwhile, the decimal point of the unit place also flashes. If
no longer switched on/off capacitor, the switching delay time will recover the
standard setting.
p
This H.S.P. Mode will be de-activated for switching on/off capacitor if the setting
of the number of switching step is less than the switching step in circular sequence.
The controller will directly switch on the capacitor (step 4) after 30 seconds beacause the
reactive power value (K Var) is higher than 4 times of the C/K value, thus the K Var value
in the system should be derived from the designed formula as 10-4=6. This way, the derived
value (10-4=6) in K Var is still higher than 4 times of the C/K value, a half of the preset
switching delay time under the
LY
mode will be activated for switching on again (new
default value has been automatically changed as 15s), and meanwhile, the decimal point of
the unit place also flashes.
p
Following up the designed formula, now the latest derived value (6-4=2) in K Var in the
system is less than the step 4 in circular sequence so the H.S.P. Mode should be de-activated.
Select the Auto mode, the H.S.P. Mode is de-activated.

Tripping setup for over voltage :

All the steps will be switched off in order once the legend

This tripping setting must be activated according to the setting of the

Auto-adjustment in inverted-phase shift ~
Y
?
Y
:
The phase-shift will be automatically reversed at 180 degrees as the measured
phase angle exceeds 90 degrees, and the displaying screen indicates
E 5
after
3 seconds. Moreover, it is unnecessary to alternate the cable in the electrical
network system except for the phase error.
This procedure is only applied to the following conditions.
1. The connected voltage terminals with the reverse polarity.
2. The direction of the measured current flow has been inverted.
