Thanks for selecting RVC range of PF controllers for your automatic
capacitor bank.
READ THIS FIRST
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. Disconnect all
power connections before working on the PF controller.
For cleaning, remove the dust with a dry cloth. Do not use abrasives,
solvents or alcohol. Before cleaning please turn off the power supply.
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.
All cables connected to the PF controller must conform to the local
regulations. They should be able to withstand at least 60°C ambient
temperature. External disconnection devices (e.g. a switch) and
external overcurrent protection devices (e.g. fuses) must be
provided for the protection of the PF controller (refer to # 6, F1 and
F2) and for the protection of the capacitor bank (refer to # 6, F3, F4
and F5). These devices must be installed in the same cubicle as the
PF controller. The typical protection level of the disconnection
circuits for the PF controller is 6A. For the capacitor bank, the
protection level depends on its rating.

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.
When an apparatus is used in a system, EU directives may require
that the system be verified for EMC compliance.
The following guidelines are helpful in improving the EMC
performance of a system:
1. Metallic enclosures generally improve EMC performance.
2. Run cables away from apertures in the enclosure.
3. Run cables close to grounded metallic structures.
4. Use multiple ground straps for doors or other panels parts as
required.
5. Avoid common ground impedances.

SWITCHING STRATEGY
Reactive power requirement is calculated based on average reactive
load during a switching delay time (40 sec. recommended).
RVC decides on the number of steps based on above and switches
on the biggest step first to avoid intermediate switching. During this
switching sequence, a fixed 12-second delay time between each
step is introduced in order to avoid transient problems and to fulfill
EMC requirements. The default switching is circular (# 8.) which
increases lifetime of capacitors/contactors.
MODES
AUTO mode (default)
RVC decides on the number of steps required to reach the target PF
based on user setting (target PF, C/k, ...)
Display of cos ϕ, Vrms, Irms, THDV, THDI. (refer to 10.1)
MAN mode
This mode allows the user to control the power factor manually.

7.2. Insert the wire in the

while keeping the pressure on
the lever.
7.3. Release the screwdriver.
7.4. The wire is properly

If the connections (CT and
voltage) are done properly, the
RVC will display the PF
measurement screen, in the
Auto mode (refer to # 10.)

AUTO SET mode
Automatic setting of PHASE, C/k, DELAY, STEPS of outputs 1, 2,
3, ... RVC makes the commissioning easy with its AUTO SET mode.
The user only needs to set the desired PF (default factory setting is
1.0) by going to MAN SET mode. This process may take several
minutes to complete. Please refer to 10.3.
Note: the default time delay is set at 40 sec. If a different delay time
is needed, please do it before starting the AUTO SET procedure.
MAN SET mode
Manual setting of COS ϕ, PHASE, C/k, DELAY, STEPS of outputs 1,
2, 3, ..., Vrms Max, Vrms Min, THDV Max.
Please refer to § Programmable parameters and to 10.4.
Apart from these parameters, RVC has some special features like
target PF in regenerative mode, linear or circular switching mode,
overvoltage and undervoltage threshold limit. (refer to 10.4.)
Note: any parameter set automatically by the controller can later be
overwritten by the user by using MAN SET mode.
PROGRAMMABLE PARAMETERS
Following are the user programmable parameters with acceptable
values indicated.
COS
ϕϕ
The controller has to reach the target cos ϕby switching steps.
0.7 ind cos phi 0.7 cap.
PHASE
Used to correct the phase shift due to all possible connections of CT
and voltage circuit (refer to # 11.)
en
RVA Manual TEXT-final.qxd 5/12/2005 16:57 Page 7

C/k
It is the sensitivity of the controller which is set to about 2/3 of the
current of the smallest switched step. C/k is related to the power of
smallest step (Q in kvar), V (nominal voltage in V), k (CT ratio).
0.01 c/k 3.00 (refer to # 9. C/k table for a 3-phase / 400V
system, or use formula given in # 9. for other cases).
DELAY
1 sec switching delay 999 sec. Default setting is 40 seconds.
STEPS
There are max. 12 outputs, each can be set from 0 (disabled), 1...9,
or F (fixed).
‘1’ represents the smallest switched step (refer to c/k ratio). A typical
sequence could be 1:1:2:4... for a 200 kvar bank with 25 kvar as
smallest (represented by ‘1’) and 100 kvar as biggest (‘4’) steps.
‘0’ means that the output is never connected.
‘F’ means that the output is always connected unless a protection
event arises.
FEATURE 1: Linear / circular (refer to # 8.)
Linear: last in first out Circular: first in first out
FEATURE 2: Generative / regenerative target cos
ϕϕ
An alternative target cos ϕis activated when power flow is reversed
(P < 0).
- 0.7 cos phi - 1.0.
The negative sign indicates regenerative mode.
Protection 1 & 2: Overvoltage (Max Vrms)/undervoltage (Min Vrms)
User settable parameter for protection of capacitor bank.
Recommended values: 0.9 Vnom < Vmin ; Vmax < 1.1 Vnom.
If the system voltage exceeds this limit, all steps are disconnected
one by one. In case of undervoltage, the disconnection is faster (< 1
network period).
Below certain specified voltage, these protections are disabled. This
condition is shown by a “ “ display on the screen.

RVA Manual TEXT-final.qxd 5/12/2005 16:57 Page 8

Protection 3: Over THDV (Max THDV)
If the THDV exceeds this over THDV limit set by the user, all steps
are disconnected. The reset delay time (default 40 sec) is
automatically doubled each time this event takes place.
Below certain specified THD level, this protection is disabled. This
condition is shown by a “ “ display on the screen.
ALARM AND PROTECTION
RVC controller has a Normally Open (NO) type of alarm contact.
This contact activates (OPEN) when the following situation arise:

Fault
The controller does not switch
on or off steps although there is
a considerable variable inductive
load.
The controller does not seem to
activate any steps.
One of the arrow indicators
flashes.
The preset power factor is not
achieved.
All capacitors are switched on
although the required reactive
power is relatively low.
The controller is connected but
does not work (nothing on
display).
The AUTO SET procedure stops
and the controller displays an
error message “FXX”.
All capacitors are switched off
and the alarm icon is on for more
than 40 sec.
Solution
• Check that the controller is in
automatic Mode.
• Check setting of phase shift
and C/k.
• Check that the CT short-circuit
bridge is removed.
Wait for the delay time between
switching and/or the power
outage delay time.
Normal situation when the actual
inductive current varies around
the set sensitivity (C/k).
At low or no load, a low power
factor can correspond to a very
small inductive current. The
corresponding capacitor steps
are too large for compensation.
If the average cos ϕover a
period of time is too low, the
preset cos ϕmay be increased.
Check settings of phase and C/k
values.
Check the voltage protection
settings, fuses and voltage
supply.
Please identify the meaning of
the error message (see table on
next page) and act accordingly.
Check the network voltage and
Vmax / Vmin / THDV max
protection parameters.
