5.1 SETTING PROCEDURE See diagram in 5.2
Press the button twice so that the selected sequence is displayed.
Press once and then change the displayed number to equal the security code (located on the
rear label) using the or buttons. The code is accepted when is pressed.
The alarm indicator “ “ flashes when the setting mode is entered.
The settings can now be displayed by repeatedly pressing and releasing to loop through them.
Adjust each setting, as required, using or .
Press and hold until “End” is displayed and press to return to normal operation.
Display :
a) Sequence :
Set the Sequence required from 00 to 07. Further details and explanation
about these sequences are provided in Section 6, SEQUENCES.
b) Safety Lockout time :
Set the safety lockout time to suit the installation. The available times are from
10 to 600 seconds in 10 second increments.
c) Stage limit :
Set this (from 1 to 6) to the number of capacitor stages to be controlled.
d) c/k :
Setting range = 0.03 to 1
where V = nominal primary system voltage.
I = primary rating of the current transformer.
Example :
Smallest capacitor step size = 100 kvar
CT primary rating = 500 A
Primary system voltage = 3300 V
a) Target cosϕ :
Setting range : 0.80 lagging
to 0.95 leading (additional c displayed)
b) Harmonic alarm : OPTIONAL
The harmonic resonance detection level is from 1% to 5% in increments of 1%.
It can be disabled by selecting the final position (above the 5% setting)
designated “hOFF”.
c) Switching type :
Rotational → “On” / Linear → “OFF”
d) Stepping type :
Single → “OFF” / Double → “On”
e) Phase :
Three phase connection (P3) or single phase (P1) can be selected.
