1. INTRODUCTION
RGN-B06 is a safe and efficient unit that utilizes advanced technology and engineering methods to feed the energy which is
potentially to be lost on brake resistors, into current mains when motors in lift systems run as generators.
•RGN-B06 supplies the grid with true sine wave with low harmonic distortion, utilizing high resolution PWM methods
and Vector control techniques.
•It gives fast in response to grid fluctuations thanks to its optimized software.
•Can be integrated to lift control systems by control inputs, relay outputs and CANBUS port.
•Start conditions and input voltage to reach the maximum power can be configurable.
•RGN-B06 has a user interface to configure all its parameters which have been kept simple for easy installation.
•RGN-B06 saves statistics such as regenerative travel count and produced energy.

3. RGN-B06 OVERVIEW
Motors in lift systems act as power generators when travelling downwards with heavy load or upwards with light load. During
the breaking period this power is even higher. This energy causes internal bus voltage to rise. Traditionally, over a safety level
of bus voltage, break resistors are used to waste this energy as heat. RGN-B06 feeds this potentially lost energy back to the
utility grid. It can be connected to the brake resistor in parallel.

12. INSTALLATION AND COMISSIONING
Each RGN-B06 unit is tested at factory and shipped ready to install. Still it is suggested to follow the steps below for safe
installation and commissioning.
•Connect PE and Grid R-S-T cables.
•Internal circuits are fed from grid connections. Turn the grid energy on and check the grid voltage, grid frequency and
the internal bus voltage on INFO/NOW screen (Should be around 400V –50Hz –540V).
•Check the control inputs and relay outputs on INFO/NOW screen (All should be “-“).
•Change the parameters if needed.
•Turn off the grid.
•Connect DC Input cables and input-output wires.
•Turn on the grid.
•Check the DC Input Voltage at INFO/NOW screen. (Should be around 540V)
•“READY” message should appear at the screen.
13. STARTUP SETTINGS
RGN-B06 unit is configured at factory for common needs. If “BAD CONFIGURATION” message does not appear on the
screen the unit is ready to use after electrical installation. In case it is decided to change some parameters “SAVE” function
must be run to save the parameters to permanent memory. Mind the following warnings in case you change parameters.
LANGUAGE: The language that is valid on all screens is preferred.
HIGH VOLTAGE/LOW VOLTAGE: When the grid voltage runs out of these values the unit stops running. If the grid
quality is bad and device frequently stops running because of grid error, try to change these parameters, otherwise do not.
START MARGIN: RGN-B06 unit observes the difference between DC Input voltage and regulated grid voltage to decide
whether the motor is in regenerative mode or not. If the difference is higher than the configured margin it starts transferring
energy to the grid. It is not suggested to set this parameter too high since it would cause system run at high bus voltages at
every regenerative tour.
FULL POWER VOLTAGE: RGN-B06 unit’s trajectory curve is dynamically calculated such that it reaches its maximum
power at the configured voltage level. Therefore voltage level at which break resistors are activated is an appropriate selection
for this parameter.
