About this Instruction Manual
This Instruction Manual is designed to help you quickly install and operate the RVC Controller.
Before installation and operation of the RVC Controller, read this notice carefully. Keep it at the
disposal of people in charge of installation, maintenance and operation.
Safety
Installation, maintenance and operation of the PF Controller must be performed by qualified
electricians.
Do not work under voltage.
Do not open the PF Controller’s housing. There are no user serviceable parts inside.
The PF Controller is connected to a current transformer. Do not unplug the current transformer
connections before making sure it is short-circuited or connected to another parallel load of
sufficiently low impedance. Failure to do so can create dangerous over voltages.
Do not use this product for any other purpose than its original aim.
Electromagnetic compatibility
This PF Controller has been verified for compliance with EU (European Union) directives for
EMC (electromagnetic compatibility) for operation at 50 Hz and bears the CE marking to this
effect.
Useful guidelines for improvement of EMC performance may be consulted in chapter 14
Electromagnetic Compatibility.

5. Switching strategy
Steps switching is based on the average value of the reactive power consumption of the load
during the switching delay time.
It allows:
• to control the PF in the presence of rapidly varying loads
• to use a longer switching delay time and as a result, to reduce the number of switchings.
On the basis of the reactive power demand measured during the switching delay time, the
RVC identifies the number of steps to be switched on.
It then automatically switches the bigger outputs first to avoid unnecessary intermediary
switchings.
During this switching sequence, a fixed 12-second delay time between each step is
introduced in order to avoid transient problems and to fulfil EMC requirements.
When several steps must be switched off, the controller does it in one shot because capacitor
switch-off is transient-free.
All the switching sequences are circular.
Circular switching increases the lifetime of capacitors and contactors by balancing the
switching stress among all the outputs.
In case of “double first step” (1:1:2:2…; 1:1:2:4:4:…; 1:1:2:4:8:8:..), the circularity applies to
the first two outputs and also on the outputs of higher value.
6. Modes
AUTO Mode
• Steps are automatically switched on and off to reach the target cos ϕaccording to the
measurement of the reactive current, the C/k setting, the switching delay, the number of
outputs and the type of sequence
• The LCD display shows the actual cos ϕ

13
MAN Mode
• Steps are switched on and off manually by pressing + and - buttons
• The LCD display shows the actual cos ϕ
AUTO SET Mode
Automatic setting of the following parameters:
•C/k: automatic setting of the sensitivity
•PHASE: automatic connection recognition (including inverted CT leads and single phase)
•DELAY: automatic setting of the switching delay time to 40s
•OUTPUT: automatic recognition of number of outputs
•SEQUENCE: automatic recognition of type of sequence
Factory default target cos ϕ: 1.00
MAN SET Mode
Manual setting of the following parameters:
•COS ϕ: target PF
•C/k: PF controller sensitivity
•PHASE: phase connection
•DELAY: switching delay time
•OUTPUT: number of outputs
•SEQUENCE: type of sequence
7. Programmable parameters
COS
ϕ
It is the target power factor that the PF Controller has to reach by switching steps. The value
can be set between 0.70 inductive and 0.70 capacitive in the Manual Set Mode (MAN SET –
COS ϕ).

14
C/k
C/k is the sensitivity of the PF Controller. It is usually set equal to 2/3 of the current of the first
capacitor step. It represents the threshold current value for the PF Controller to switch on or
off a capacitor step.
The C/k can be programmed from 0.050 to 1.00.
The value can be set either automatically (AUTO SET) or manually (MAN SET – C/k).
Phase shift
If the RVC is connected as shown on the connection diagram of the PF Controller, the phase
shift is 90° (default setting).
For special connections, please refer to chapter 10 – Programming.
Setting the phase shift may be done either automatically (AUTO SET) or manually (MAN SET –
PHASE).
Switching delay
The default value of the switching delay time between steps is 40s and can be programmed
from 1s to 999s.
Setting of switching delay time may be done manually (MAN SET – DELAY)
Output
Output represents the number of physical outputs and can be programmed from 1 to 12
according to the RVC type.
Setting the output may be done either automatically (AUTO SET) or manually (MAN SET –
OUTPUT).
Sequence
Switching sequences allowed by the RVC Controllers are:
1:1:1:1:1:...:1
1:2:2:2:2:...:2
1:2:4:4:4:...:4
1:2:4:8:8:...:8

9. Easy Commissioning
Step 1. Energize the PF Controller
Note: If you have a short-circuit on the CT’s secondary winding
do not forget to open it after having connected the current
input of the PF Controller.
After a power outage, the reset delay time is 40 seconds.
During this delay time, the alarm icon blinks and the alarm
contact remains closed.
The AUTO Mode is activated and the LCD display indicates
the cos ϕmeasurement.
WARNING: for automatic capacitor banks with a switching
delay time greater than 40s., set delay time before starting
Autoset (see chapter 10).
Step 2. Activate the AUTO SET Mode by
pressing twice the Mode button.
AU appears on the LCD display.
Step 3. Press the + and – buttons simultaneously
to start the automatic setting.

AU starts flashing.
C/k, phase, output and sequence are automatically set.
The switching delay time is also set to 40 seconds except if a
higher value has been previously programmed. Any lower value
is erased and replaced by 40 seconds.
During this procedure which may take several minutes, the
capacitor steps are activated.
The setting procedure is finalized once AU stops flashing.
If the load is changing rapidly, the controller may have to switch
on steps several times.
If an error is detected, the Autoset procedure is stopped and an
error message is displayed.
Re-start the procedure once the fault has been corrected.
Please refer to chapter 13 for a complete description of error
messages and solutions.
Step 4. Press the Mode button once to
activate the manual setting of the target cos
ϕ
.
The already programmed value is displayed. If the RVC has
never been programmed before, 1.00 appears on the LCD
display.

iindicates a capacitive PF.
Step 6. Reactivate the AUTO Mode by using
the Mode button repeatedly.
During this procedure, the values of the parameters
automatically set in the previous step will be displayed.
All parameters are also programmable manually (see
chapter 11).
Once in AUTO Mode, the RVC automatically switches on the
necessary steps to reach the programmed target cos ϕ.
The actual cos ϕappears on the LCD display.
Note: a negative cos ϕindicates that the load is re-injecting
reactive power on the network. The RVC continues to work
normally.
