1.2 Front Panel
On the front panel, 3 display lines, 4 buttons and also alarm, capacitor
step and display leds exist. Measured parameters are observed in the
related displays. Displayed values for related parameters are selected via
indicator leds. When an alarm exists, related alarm led blinks. 12 capacitor
step leds indicates, which capacitor step is switched on. Detail information
about buttons, display, alarm and capacitor step leds will be explained
in the coming sections.

1. INTRODUCTION
1.1 General Information
Power factor controllers are used for measurement and control of power
factor control units for central reactive power compensation. The power
factor, which is defined as ratio of active power (W) to apparent power
(VA), measured by power factor controller is compared with the set values
to provide necessary compensation.
RM-12P power factor controller is designed for reactive power compensation
in single phase and 3-phase systems.
RM-12P compensates each phase separately and so, this makes
RM-12P series a unique solution for unbalanced load compensation. In
order to perform this process, single phase and 3-phase capacitor steps
must be connected to the device at the same time.
