1. INTRODUCTION
The VSD-R 4-20mA Box is a specialised air
compressor supervisory and control unit
designed to function in cooperation with a
‘Variable Frequency Inverter Drive’ panel
equipped with a drive unit that has a 4-20mA
speed control input. The VSD-R is also
designed to function in cooperation with a
management system unit.
The VSD-R can be integrated with a
compatible VSD/VFD panel to convert a fixed
speed, load/unload, air compressor into a
variable speed unit with advanced
management system supervisory and control
functionality. The VSD-R will provide all
required functionality to enable total synergy
with the energy control, VSD compressor
aware, functions of the management system
unit.
Each air compressor in a system, that requires
VSD-R integration, must be equipped with an
individual VSD-R Box and VSD panel. A
management system unit can accommodate
multiple VSD-R Boxes.
1.1 VSD/VFD Unit Basic Requirements
Variable Speed Drive
Variable Frequency Drive
Frequency Inverter Drive
Ensure the VSD/VFD is equipped with a 4-
20mA speed reference input and functions in
accordance with the 4-20mA signal:
20mA = maximum loaded motor speed.
4mA = minimum loaded motor speed.
Ensure the VSD/VFD is equipped with an input
that will allow the drive to start and stop in
response to a remote volt-free switching
contact.
Open Circuit = Stop
Closed Circuit = Start/Run
The VSD/VFD must be equipped with a volt-
free switching contact output that is normally
closed circuit and will open in the event of a
drive fault. The contact should close within 2
seconds at power-up, and remain closed when
the drive is stopped, unless a fault condition
occurs.
1.2 Compressor Basic Requirements:
Ensure all basic requirements are meet prior
to installation. Air compressors that fail to meet
all the basic requirements are not suitable for
variable speed conversion using this product.
1) The air compressor must be equipped with
a load/unload regulation system and, if not
regulated with a single electro-mechanical
pressure switch, have a facility for remote
load/unload control with the ability to accept a
volt free switching contact input for remote
load/unload.
A VSD-R will accommodate a pressure control
range, when fitted with an appropriate sensor,
of 1bar to 600bar.
2) The compressor main drive motor must be
suitable for variable speed ‘inverter drive’
operation. In general, the majority of standard
induction motors manufactured from 1990
onwards are suitable for ‘inverter drive’
operation; although they are generally
restricted to a maximum turndown capability of
50% full operating speed. If in doubt, contact
the air compressor or main motor supplier.
3) The compressor main motor must be fitted
with a contactor, or start/delta contactor set,
that is capable of isolating the motor from the
power supply in emergency stop situations.
4) The compressor must be equipped with a
controller or controlling system that has full
main motor and regulation control functionality
for the compressor.
5) The compressor must be equipped with a
controller or controlling system that has all
required air compressor unit safety functions
and features installed and operational.

1.3 General Operation
The VSD-R Box, in conjunction with a
compatible VSD/VFD panel, will control the
speed of an air compressor’s main motor in
response to pressure variations (demand).
The VSD-R Box, VSD Panel and air
compressor combination can function as a
‘stand-alone’ VSD air compressor unit or
operate in conjunction with a management
system unit.
The VSD-R Box performs all pressure
regulation functions and controls the
compressor using load/unload commands (1).
This is achieved by integration of the
compressor unit’s pressure switch with an ‘i-
PCB’ or using the compressor controller’s
remote load/unload input. The air compressor
control system will respond in an identical
manner as if the VSD-R Box was a remote
regulation/sequencing unit.
Run operation of the main motor is derived
from the air compressor controller’s main
motor control outputs (2). The main drive
motor will only operate when the compressor’s
controller is requesting the main motor to run.
This functionality ensures all compressor
controller proprietary and safety features and
function, regardless of how they are
implemented or derived, remain intact.
The VSD-R Box controls the compressor’s
main motor contactor, or star/delta contactor
set, and will operate the contactor(s) in
response to a run request from the
compressor’s controller. The VSD-R Box
monitors the operation of the compressor
contactor(s) and will only operate the VSD
panel (5) to apply power to the compressor’s
main motor (6) when the contactor(s) have
energised correctly (4).
The compressor contactor(s) are used for
safety isolation only and will operate differently
than previous. The contactor(s) will energise
prior to power being applied to the main motor
and de-energise after power is removed from
the main motor. This functionality will
significantly prolong the service life of the
contactor(s) contacts; the contacts are no
longer subjected to high starting current flow
or high current disconnections during a motor
stop.
The compressor controller will be unaware of
the VSD-R Box control of it’s main motor and
will continue to respond as if the motor was
still under normal fixed speed control.
Any star/delta timing implemented in the
compressor controller can remain; the main
motor will use this time to accelerate to
operational speed.
Any motor run-on time implemented in the
compressor controller can also remain;
although in some instances it may enhance
efficiency to reduce this time.
The VSD-R Box monitors the compressor to
ensure that a response to a VSD-R Box load
request is actioned appropriately by the
compressor controller; a fault condition is
generated if correct response is not detected.

B) VSD Panel
C) Compressor Controller
When the compressor is loaded the VSD-R
Box will vary the speed of the compressor’s
main motor is response to pressure variations
(demand). When the compressor is unloaded,
but the compressor controller is still requesting
the main motor to run (run-on time), the VSD-
R Box will run the motor at a pre-defined ‘off
load’ speed regardless of pressure variation.
The VSD-R Box will stop the main motor, in a
controlled manner, when the compressor
controller no longer requests the motor to run.
This will occur when the VSD-R Box has
requested the compressor to ‘off load’ and the
compressor controller’s run-on time has
expired.
In an emergency stop, or trip, situation the
VSD-R Box will remove power from the main
motor and de-eneregise the compressor’s
contactor(s) immediately.

2. MENU NAVIGATION
Display Item Structure:
All value, parameter or option selection
displays are grouped into menu lists. Items are
assigned to a list according to type and
classification. Items that can be used to select
options or modify functions are assigned to
‘menu mode’ lists. Items that a User may
require to view during routine operation,
detected pressure for example, are assigned
to the normal operational mode list. Lists are
identified by page number; the normal User
display list is page ‘P00’. All parameters and
options are assigned to menu mode pages
‘P01’ or higher. All Page ‘P00’ items are view
only and cannot be adjusted.
Normal Operational Mode (Page P00):
At controller initialisation, all display elements
and LED indicators are switched on for three
seconds, the display will then show the
software version code for a further 3 seconds
before initialisation is complete and the normal
operating display (Page P0) is shown. In page
P00 ‘normal operational display mode’ the
main display will continuously show the
detected delivery pressure and the Item
display will show the first item of the ‘User’
menu. User menu ‘Items’ can be selected
using the Up or Down buttons at any time.
Pressing the Enter button will lock any
selected Item display and inhibit return to the
default display. When an Item display is locked
the lock key symbol will slow flash. To unlock
an Item display press Up or Down to view an
alternative Item display or press Reset or
Escape. No Item values, options or
parameters can be adjusted in page ‘P00’. If a
fault condition occurs the fault code becomes
the first list item and the display will
automatically jump to display the fault code.
More than one active fault code item can exist
at any one time.
Access Code:
Access to page list displays higher than page
‘P00’ is restricted by access code. To access
menu mode pages press UP and DOWN
together, an access code entry display is
shown and the first code character will flash.
Use PLUS or MINUS to adjust the value of the
first code character then press ENTER. The
next code character will flash; use UP or
DOWN to adjust then press ENTER. Repeat
for all four code characters.
If the code number is less than 1000 then the
first code character will be 0(zero). To return
to a previous code character press ESCAPE.
When all four code characters have been set
to an authorized code number press ENTER.
An invalid code will return the display to
normal operational mode; page ‘P00’.
Access Code Timeouts:
When in menu mode, if no key activity is
detected for a period of time the display will
automatically reset to the normal operational
display; Page ‘P00’.
Menu Mode Navigation:
In menu mode the main value display will flash
and show the Page number. To select a page
press UP or DOWN. For each page the
display will show the first Item of the page list.
To view a page list press ENTER, the Page
number will stop flashing and the Item display
will flash. Press UP or DOWN to view the
selected page list items. To select an Item
value for modification press ENTER, the Item
display will stop flashing and the Value display
will flash. The value or option can now be
modified by pressing UP(Plus) or

3.4 Operation
The VSD-R Box and VSD Panel operate in
conjunction with the compressor; all units must
be functional for the compressor to operate
and run.
The compressor must be in a started state
(running or in standby) before VSD-R Box
motor and pressure control will function. The
VSD-R Box will show a compressor fault
indication if the compressor is not locally
started.
The VSD-R Box is always active and does not
need to be started; start and stop have no
function. The VSD-R Box will automatically
recover and become active when power is re-
established after a power disruption or lose. It
is recommended that the compressor
controller is equipped with a ‘power failure
automatic restart’ facility.
Pressure regulation control will
default to ‘local’ (in accordance with the set
VSD-R Box upper and lower pressure
settings) if communications with the
management system is disrupted or lost.
When communications are re-
established the VSD-R Box will automatically
re-activate ‘Remote regulation control’ and
function in accordance with the management
system.
The detected status of the compressor is
indicated by the VSD-R Box display status
symbols (see Status Symbols)

menu item press ENTER; the ‘lock’ key
symbol will appear. Press UP or DOWN at any
time to select another item and unlock the
User menu item display.
Percentage Motor Speed:
The percentage of detected motor speed
compared to maximum motor speed. This
value provides a direct indication of variable
speed compressor output regulation.
3.6 Compressor Not Responding
When the VSD-R Box requires the
compressor to operate a ‘Remote Load’ signal
is activated. The compressor must respond to
this by returning a ‘Run Request’ signal to the
VSD-R Box to start and run the main motor
(the compressor has full control of motor
start/stop). If a ‘remote load’ signal is issued
but no ‘run request’ response is detected
within 60 seconds, the VSD-R Box will assume
the compressor is ‘not available’ regardless of
a good ‘Ready’ condition signal from the
compressor.
In this instance the ‘remote load’ signal is
pulsed every 10 seconds and the VSD-R Box
will indicate the compressor as ‘Not Available’
until a response is detected.
The ‘Not Available’ condition will automatically
reset when a response is detected.
If this condition occurs, check that the
compressor has been started.
