1. INTRODUCTION

1.1 About User Manual

This User Manual is designed to help you for quick installation of RG-6T. Before installation
and operation, please read this section very carefully.

1.2 Precautions for Safe Use and Installation

- Failure to follow those instructions will result in death or serious injury.

- Disconnect all power before working on equipment.

- When the device is connected to the network, do not remove the back panel.

- Do not try to clean the device with solvent or the like. Only clean the device
with dried cloth.

- Verify correct terminal connections when wiring.

- Electrical equipment should be serviced only by your component seller.

- Only for rack panel mounting.

- An F type fuse must be used and its current limit value must be 6A.

- No responsibility is assured by ENTES A.S or any of its subsidiaries
for any consequences arising out of the use of this material.

2. GENERAL

Power Factor Controllers are used for measurement and control of power factor control units
for central reactive power compensation. The Power Factor measured by RG-6T is compared
with the set point values and in order to provide necessary compensation, Power Factor
Controller switches capacitor banks ON and OFF automatically. RG-6T is a microcontroller
relay, designed for above application in 144x144 and 96x96 (only RG-6T) case for flush
mounting with rear plug-in connectors. In addition to displaying the system’s Cosϕ in Automatic

Operating Mode, RG-6T displays the RMS values of Voltage(V) and Current (I), Active
Power (W), Reactive Power (VAr) and Apparent Power (VA) of measuring phase.

5. CONTROLS AND MENU OPERATIONS

All settings are made by Menu. The set values except operating mode are kept in memory

5.4 Step Time Adjustment

SET

even if the device is switched off.When it is switched on, it starts compensation with the
values stored in the memory in Automatic Operating Mode. After entering Menu by pressing
SET button for 3 seconds and if you don’t make any adjustments during 20 seconds ,RG­6T operates with the previously stored values.
To quit Menu without any storing operation, UP or DOWN buttons are pressed

UP
