Net$ync II Conductor 4
2. INTRODUCTION
2.2 Pressure Detection and Control
The Net$ync II Conductor 4 a specialised
supervisory and control product designed to
provide energy efficient optimised pressure
and sequence management of up to 4 air
compressors operating on a common air
system. The Net$ync II Conductor 4 general
operating mode can be modified by a number
of adjustable parameters and priorities to
enable operation to be matched to site
requirements and characteristics.
The Net$ync II Conductor 4 utilises the signal
from an electronic pressure sensor that can be
mounted remotely from the Net$ync II P4 in a
suitable location in the compressed air
system.
2.1 Compressor Connections and Control
As default the Net$ync II Conductor 4 set-up
for operation with a 16bar (232psi) pressure
sensor but can accept input from any 4-20mA
type pressure sensor with a range from 1.0bar
(14.5psi) up to 600bar (8700psi).

Each air compressor in the system can be
integrated with the Net$ync II Conductor 4 using an
interface module that is designed to enable
connection to almost any positive
displacement air compressor (regardless of
make or manufacturer) that operates using a
single pressure switch type control with a
control voltage between 12V to 250V, 50 or
60Hz.
The interface module is
installed within the
compressor control area
and connected to the
Net$ync II Conductor 4
using a sixwire cable.
Each 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 a remote
load/unload control with the ability to accept a
volt free switching contact input for remote
load/unload.
Consult the air compressor manual or your
air compressor supplier/specialist for details
before installing the Net$ync II Conductor 4.

3. Features and Functions
3.1 Pressure Control:
The primary function of the Conductor 4’s pressure
control strategy is to maintain system pressure
between the ‘High Pressure’ set point (PH adjustable) and the ‘Low Pressure’ set point
(PL - adjustable) in conjunction with targeting
optimum achievable system energy efficiency.
The P4 calculates a ‘Target’ pressure level
(PT), the mid-point between the two set points,
which is used as the nominal ‘target’ pressure
level for the system.
a
If demand for air is abruptly, or significantly,
increased, and the capacity output of the
compressor loaded at the Low Pressure set
point (b) is insufficient, the pressure will
continue to decrease at a reduced rate.
The Conductor 4 will accommodate for this event by
loading an additional compressor.
The instance at which the additional
compressor is loaded (c) is dynamically
calculated and is determined by the rate of
pressure decrease (the urgency or time limit)
and the acceptable deviation of system
pressure (the ‘Tolerance’) from the normal
control limits.
PH

When system pressure increases to the High
Pressure set point (a) a compressor is
unloaded. Pressure is allowed to decrease to
the Low Pressure set point (b) before a
compressor is loaded again to add capacity
output and increase pressure. This process
will continue under a steady demand for air in
a continuous stable cycle.
For systems that consist of a variable capacity
(or variable speed) compressor, the
compressor must be set, or controlled, to
achieve and maintain the calculated system
‘Target’ pressure level (PT).
PH
PT
PL
Where abrupt, or significant, changes in air
demand, beyond the capacity scope of the
variable capacity compressor, are
experienced, the loading and unloading of
other compressors is implemented in exactly
the same way as described above.
Page 4
PL
c
The same method is implemented in reverse
(above the High Pressure set point) when an
abrupt, or significant, decrease for air demand
is experienced.
Rate of change of pressure, and the stability of
pressure control, is largely determined by
system volume and the scale, and/or
abruptness, of air demand fluctuations; these
characteristics will differ from installation to
installation. To accommodate for variations in
installation characteristics the ‘Tolerance’
pressure level (TO) and an influence on the
dynamic reaction time (or ‘Damping’) of the
Conductor 4 (DA) is adjustable.
Net$ync II Conductor 4
3.2 Tolerance:
3.3 Damping:
Tolerance is a pressure band above and
below the set pressure control levels that
accommodates for an exceptional instance of
abrupt and/or significant increase, or
decrease, in demand without compromise to
optimal energy efficient control.
In situations where the loading of an additional
compressor, at the PL pressure set point, is
inadequate to match a significant and/or
abrupt increase in air demand the additional
reaction of the Conductor 4, while pressure deviates
into the ‘tolerance’ limit, is dynamically calculated.
The time before an additional compressor is
loaded, to increase generation capacity
further, will vary in accordance with the
urgency of the situation.
PH + TO
TO
PH
PT
PL
TO
PL - TO
Tolerance (TO) is expressed as a pressure
defining the width of the tolerance ‘band’.
For example; a tolerance setting of 3psi
(0.2bar) means the Conductor 4 will implement
appropriate optimal energy efficient
response(s) during a deviation of pressure
3psi below the set PL pressure level. If
pressure ever deviates beyond the ‘tolerance’
limit the Conductor 4 will proportionally increment
an emergency response, abandoning optimum
energy efficiency, until pressure is returned to
normal levels.
If system volume is inadequate, and/or
demand fluctuations are significantly large, it is
advisable to increase the ‘Tolerance’ band to
maintain optimum energy efficiency, and
reduce over-reaction, during such transition
periods.
If system volume is generous, rate of pressure
change is slow and demand fluctuations are
insignificant and gradual, the ‘Tolerance’ band
can be reduced to improve pressure control
without compromise to optimum energy
efficiency.
The Conductor 4’s dynamic reaction algorithm is
pre-set by default to accommodate for the majority of
installation characteristics.
In some situations, of which the following are
examples, the rate of pressure change may be
aggressive and disproportionate:
a) Inadequate system volume
b) Excessive air treatment equipment
pressure differential
c) Inadequately sized pipe work
d) Delayed compressor response
In such instances the Conductor 4 may over-react
and attempt to load an additional compressor that
may not be necessary once the initial
compressor is running, loaded, and able to
contribute adequate additional generation
capacity. If an increase in the ‘tolerance’ band
is insufficient, the Conductor 4’s dynamic reaction
response can be influenced by increasing the
‘Damping’ factor (DA) reducing tendency to
over-react.
The ‘Damping’ factor is adjustable and scaled
from 0.1 to 10 with a default factor of 1. A
factor of 0.1 equates to 10 times faster than
default and a factor of 10 equates to 10 times
slower than default.

3.4 System Volume:
3.3.1 Fixed Cascade Mode
This mode is intended for special
applications and is not recommended for use
in normal situations. Avoid setting the damping
factor to ‘0.0’ unless the installation specifically
requires this mode of operation.
To implement fixed pressure set point
‘cascade’ mode adjust the ‘damping’ factor
(DA) to 0.0(zero). In this mode automated
single pressure band control is disabled and
each compressor is assigned fixed load and
unload pressure set points; simulating a
multiple pressure switch cascade system. The
set points are determined by the PH (unload)
and PL (load) pressure levels and are
‘cascaded’ below these settings at differentials
determined by the set ‘tolerance’ band (TO).

The pressure set points are not dynamic

running as demand increases.

mode of operation.

Pressure control of a system is a ‘feedback
loop’ response derived from increasing, or
decreasing, air generation output capacity. If
output capacity is greater than demand for air
the pressure in a system will increase, if
demand is greater than output capacity system
pressure will decrease. The rate of change of
pressure to changing generation and demand
capacity situations is largely dependant on
system volume. If system volume is small in
comparison to recommended size the rate of
change of pressure will be fast and abrupt
inhibiting effective control and compromising
optimum system energy efficiency. If system
volume is large the rate of change of pressure
will be slow and gradual. In this instance an
enhanced control of pressure can be
achieved, the system response times can be
reduced and optimum system energy
efficiency will generally be increased as a
result.
The rule below provides an approximation for
recommended minimum system volume:
1) For systems comprising of fixed capacity
output (or fixed speed) compressors:
m3 = (m3/min) / (bar.g – 1)
The approximation only works in metric
units; convert psi and ft3 to metric units first.
1.0 m3 1.0 m3/min
1.0 bar = 35.315 ft3
= 35.315 cfm
= 14.5 psi
Example: for a system that operates with a
maximum normal demand air flow of 36m3/min
at a nominal pressure of 7.0bar =
36m3/min / (7.0bar – 1) = 6.0 m3 (212 ft3)
2) For systems consisting of variable output
capacity (or variable speed) compressor(s) the
system volume should be doubled.
m3 = 2 x ((m3/min) / (bar.g – 1))
Net$ync II Conductor 4
3.5 Sequence Control Strategies:
The Conductor 4 provides three basic sequence
control strategies or modes. Each sequence control
strategy consists of two sub strategies:
1) The compressor ‘Rotation’ strategy
2) The compressor load ‘Control’
strategy
The ‘Rotation’ strategy defines how the
compressors are re-arranged, or re-ordered, in
to a new sequence at each routine ‘Rotation’
event. Rotation events are triggered by a
cyclic interval time, a set time of day each day,
or a set time of day once a week.
The compressor load ‘Control’ strategy
defines how the compressors are utilised in
response to variations in system pressure.
Compressor Sequence Arrangements:
Each compressor in a system is initially
assigned to the Conductor 4 with a fixed and
unchanging number reference, 1 to 4.
The ‘duty’ that a compressor is assigned in
any set ‘Rotation’ sequence arrangement is
defined by a letter, A to D.
A = the ‘Duty’ compressor, the first to be
utilised.
B = The ‘Standby’ compressor, the second to
be utilised.
C = The ‘Second Standby’ compressor, the
third to be utilised.
D = The ‘Third Standby’ compressor, the forth
to be utilised.
Compressor ‘duty’ assignments are reviewed,
and re-arranged as appropriate in accordance
with the selected rotation strategy, at each
rotation event.
Equal Hours Run Mode
The primary function of EHR mode is to
maintain a close relationship between the
running hours of each compressor in the
system. This provides an opportunity to
service all compressors at the same time
(providing the service interval times for all
compressors are the same or similar).
EHR is not an energy efficient focused
mode of operation.
Rotation:
Each time the rotation interval elapses, or the
rotation time is reached, the sequence order of
compressors is reviewed and re-arranged
dependant on the running hours recorded for
each compressor. The compressor with the
least recorded running hours is assigned as
the ‘duty’ compressor, the compressor with the
greatest recorded running hours is assigned
as the ‘last standby’ compressor. For systems
with more than two compressors, the
remaining compressor(s) are assigned in
accordance with there recorded running hours
in the same way.
Example: The compressors in a fourcompressor
system have the following
recorded running hours at the ‘Rotation’ time.
Compressor 1 = 2200 hrs
Compressor 2 = 2150 hrs
Compressor 3 = 2020 hrs
Compressor 4 = 2180 hrs
The new sequence order arrangement after a
rotation event would be:
Compressor 1 = D
Compressor 2 = B
Compressor 3 = A
Compressor 4 = C
Compressor 3, that has the least recorded
running hours, will now be utilised to a greater
extent in the new sequence arrangement;
potentially increasing the running hours at a
faster rate.
The Conductor 4 continuously monitors the running
status of each compressor and maintains a
record of the accumulated running hours.
These are available, and adjustable, in the
Conductor 4’s compressor running hour’s menu.
The Conductor 4 uses these values in EHR mode.
The Conductor 4’s running hours record should be
routinely checked, and adjusted if necessary, to
ensure a close match with the actual run hours
displayed on each compressor.
If a compressor is operated independently
from the Conductor 4 the running hours record may
not be accurately updated.
The running hours meter display on most
compressors are intended for approximate
service interval indication only and may
deviate in accuracy over a period of time.

Technical Manual
Control:
Compressors are utilised, in response to
changing demand, using a ‘FILO’ (First In,
Last Out) strategy. The ‘duty’ compressor (A)
is utilised first followed by (B) if demand is
greater than the output capacity of (A). As
demand increases (C) is utilised followed by
(D) if demand increases further. As demand
reduces (D) is the first compressor to be
unloaded, followed by (C) and then (B) if
demand continuous to reduce. The last
compressor to be unloaded, if demand
reduces significantly, is (A). The compressor
assigned as (A) in the sequence is the first to
be loaded and the last to be unloaded.
First In First Out Mode
The primary function of FIFO mode is to keep
a compressor in a loaded condition for the
maximum amount of time, dependant on
demand fluctuations, while continuously
sharing regulation and utilisation among the
available compressors.
FIFO is not an energy efficient focused
mode of operation.
FIFO mode does not follow a fixed rotation
interval, or set rotation time. Compressors are
rotated at each load event. The ‘Rotation’
strategy also becomes the ‘Control’ strategy in
this mode.
Initially compressor 1 is loaded. As demand
increases compressor 2 is loaded. If demand
reduces compressor 1 is unloaded and
compressor 2 allowed to remain loaded for a
longer period. If demand increases again
compressor 3 is loaded followed by
compressor 4 as demand continues to
increase. If demand reduces compressor 2,
the compressor that has been loaded for the
longest period, is unloaded first followed by
compressor 3 if demand continuous to reduce.
If demand increases again compressor 1 will
be loaded, this strategy continuous in a cyclic
pattern.

At each load event the compressor that has
just been loaded becomes (A), the
compressor that has been loaded for the
longest period becomes (D) and is the next
compressor to be unloaded if demand
decreases.
Timer Rotation Mode
The primary function of Timer Rotation mode
is to efficiently operate a compressed air
system consisting of fixed capacity output
compressors. The routine rotation
assignments can be modified using ‘Priority’
settings to accommodate for a differentially
sized or variable capacity output
compressor(s).
Rotation:
Each time the rotation interval elapses, or the
rotation time is reached, a sequence rotation
occurs and the sequence assignment for each
compressor is re-arranged. The compressor
that was assigned for duty (A) is re-assigned
as last standby (D) and all other compressor
assignments are incremented by one.

Control:
Compressors are utilised, in response to
changing demand, using a ‘FILO’ (First In,
Last Out) strategy. The ‘duty’ compressor (A)
is utilised first followed by (B) if demand is
greater than the output capacity of (A). As
demand increases (C) is utilised followed by
(D) if demand increases further.
Net$ync II Conductor 4
As demand reduces (D) is the first compressor
to be unloaded, followed by (C) and then (B) if
demand continues to reduce.
The last compressor to be unloaded, if
demand reduces significantly, is (A). The
compressor assigned as (A) in the sequence
is the first to be loaded and the last to be
unloaded.
This feature is intended to allow the system to
react to changes in pressure target levels in a
smooth and energy efficient manner without
abrupt overreaction.

Tables:
The Conductor 4 operates in
accordance with settings that are
T01
programmed in to a number of
PH - - - menu ‘Tables’. Each table
PL - - - Pm - - - defines the operational
SQ - - - parameters and mode of
operation of the Conductor 4.
The Conductor 4 can be instructed to change from
one table to another at any time from an external
remote source or from settings in the real time
clock ‘Pressure Schedule’
This functionality enables the Conductor 4 to
switch from one set of operational parameters, and/or
from one mode of operation, to another at any
time without disruption to routine control.
Table Parameters:
Each table consists of the following
parameters; the parameters can be set
differently in each table.
1) PH: High pressure set point
2) PL: Low pressure set point
3) Pm: Minimum pressure warning level
4) SQ: Sequence rotation mode
5) 01: Compressor 1 Priority setting
6) 02: Compressor 2 Priority setting
7) 03: Compressor 3 Priority setting
8) 04: Compressor 4 Priority setting
The ‘maximum’ pressure fault level and the
rotation interval, or rotation time, are set
independently in a configuration menu and are
unchanging regardless of Table selected.
Pressure Change Time:
When pressure set points change, a change
from one ‘Table’ to another, the Conductor 4 will
increase, or decrease, the pressure target
levels towards the new table settings in a
gradual transition over a period of time.
PC
The time the system will take to complete the
transition from one pressure target to another
is determined by the ‘Pressure Change’ time
(PC). This value can be adjusted to
accommodate installation characteristics to
achieve the transition at optimal energy
efficiency.
If the Conductor 4 is able to achieve the transition
without compromising energy efficiency in a
shorter time than set, the pressure change
event time will be automatically reduced.
An aggressively short time setting will
compromise system optimal energy efficiency.
Sequence Rotation:
A sequence ‘Rotation’ event can be
automatically triggered on a routine basis
using a pre-determined interval, a predetermined
time each day or a pre-determined
day and time each week.

between each rotation event; 1 = every 24hrs
to 96 = every 15 minutes (example: 2 = every
12hrs).
Example 2:
For a four-compressor system, that includes a
compressor (for example compressor 4) that is
less efficient, or otherwise less desirable to
operate for other reasons, it may be
convenient to ensure the compressor is only
utilised as an emergency backup. To achieve
this assign compressor number 4 with a lower
priority.
Compressors 1 to 3 = priority 1
Compressor 4 = priority 2
The first automated rotation event each day
will occur at 00:00hrs and then every set
rotation interval time throughout the day.
3.6 Priority Settings:
Priority settings can be used to modify the
‘Rotation’ sequence assignment. Compressors
can be assigned a ‘priority’ of 1 to 4; where 1
is the highest priority. Any compressor can be
assigned any priority and any number of
compressors can have the same priority.
Example 1:
For a four-compressor system, that includes a
single variable speed compressor assigned as
compressor number ‘1’, it may be desirable to
ensure the variable speed compressor is
continuously utilised in any sequence
arrangement as the ‘duty’ or ‘top-up’ unit. To
achieve this assign compressor number 1 with
a higher priority than the remaining three fixed
speed compressors.
Compressor 1 (variable speed) = priority 1
Compressors 2 to 4 (fixed speed) = priority 2

Example 3:
For a four-compressor system that includes a
variable speed compressor (compressor
number 1) and a fixed speed compressor that
is only required as an emergency backup
(compressor number 4) it may be desirable to
ensure the variable speed compressor is
always utilised first, and the backup
compressor utilised last, in any sequence
arrangement.
Compressor 1 (variable speed) = priority 1
Compressors 2 and 3 = priority 2
Compressor 4 (back-up) = priority 3

Compressors can be separated in to rotation
groups. In this example compressors 1 and 2,
of a four-compressor system, have been set
as a high priority group and compressors 3
and 4 as a lower priority group. Compressors
1 and 2 will always be utilised first in any
sequence arrangement and will be rotated at
each ‘Rotation’ event. Compressors 3 and 4
will always be utilised as lower priority in any
sequence arrangement and will be rotated at
each ‘Rotation’ event.

The Prefill feature provides a controlled
and energy efficient method of increasing
pressure to normal operating levels at system
start. This feature avoids the inefficient
potential for all available system compressors
to start and load before pressure reaches the
normal operating level.
At system start (manual start or automated
start from standby) the Conductor 4 will only load
compressors that have been pre-set for prefill
operation, for a pre-set period of time. The
prefill time (PT) can be adjusted to suit system
characteristics. The aim is to increase
pressure to normal operational levels, using
only the pre-determined compressors, prior to
the prefill time expiring.
If normal operational pressure is reached prior
to the set prefill time, the prefill function will
automatically cease and normal operational
control begin. If normal operational pressure is
not reached by the end of the prefill time the
Conductor 4 will utilise as many available
compressors as required to achieve normal
operational pressure as quickly as possible. Normal
operational control will then begin.
Two prefill modes are available; both function
in the same way but differ in response to a
failure, or loss, of a prefill compressor.
Backup Mode: Compressor(s) can be preselected
as ‘Primary Prefill’ compressor(s) or
‘Backup Prefill’ compressor(s). If a primary
prefill compressor experiences a shutdown, or
is stopped, it is replaced by a pre-defined
backup compressor and prefill continues.
! X Standard Mode: If one or more of the
pre-defined prefill compressors experiences a
shutdown, or is stopped, the prefill function is
cancelled and normal operation begins.
To manually skip Prefill mode, press and
hold START for several seconds.

3.8 Pressure Schedule:
The Conductor 4 is equipped with a real time clock
feature and pressure schedule facility. The
‘Pressure Schedule’ function can be used to
provide automation of the system.
The pressure schedule consists of 28
individual settings that instruct the system to
change from one ‘Table’ to another, or put the
system in to ‘Standby’ mode, dependant on
time of day and day of the week. The pressure
schedule will cycle from 00:00 hours Monday
(day #1) to 23:59 hours on Sunday (day #7)
each calendar week.

4. Installation
It is recommended that installation and
commissioning be carried out by an authorised
and trained product supplier.
4.1 Unit Location
The Conductor 4 is wall mounting using conventional
screw fixings. The Conductor 4 can be located remote
from the compressors but within 100m (330ft)
cable length from each compressor and within
100m (330ft) cable length from the system
pressure sensor.
System pressure will be lower than the set
‘generation’ pressure due to pressure
differential losses across air treatment
equipment. The nominal system pressure will
reduce as the air treatment differential
pressure increases.

A fused switching isolator must be installed to
the main incoming power supply, external to
the Conductor 4. The isolator must be fitted with
a fuse of the correct rating to provide adequate
protection to the power supply cable used (in
accordance with local electrical and safety
regulations).

4.3 Pressure Sensor Location
The system pressure sensor (P) must be
located in a position that will continuously
experience pressure that is common to all
compressors.
Generation Side Pressure Control:
Ensure each compressor is equipped with
independent excess pressure shutdown; an
increase in pressure differential across air
treatment equipment can result in excess
compressor discharge pressure.
Regular routine monitoring of pressure
differential across air treatment equipment is
recommended.
4.4 Pressure Sensor Connection
The pressure sensor must be connected to
terminal X05 of the Conductor 4 using an earth
screened, two-core (0.5mm2 CSA minimum),
cable no greater than 100m (330ft) in length.

4.5 Compressor Interface Q485
The ‘Q485’ is designed to interface a
compressor with the Conductor 4 using a 6-core,
earth shielded, cable no greater than 100m (330ft)
in length.
Each compressor in the system must be
assigned a unique identification number from
1 up to the number of compressors in the
system. The identification number should be
clearly indicated on each compressor for
operational reference.
For each compressor connected to the Conductor
4 utilising an ‘Q485,’ the signal wires must be
connected to the Conductor 4 terminals dedicated
for the assigned compressor reference number.
The ‘Q485’ uses a 12V to 250V input voltage
detection system and universal relay contact
control outputs (250V ‘CE’ / 115V ‘UL’ @ 5A
maximum). Integrated directly into the circuits
of an air compressor, the ‘Q485’ avoids the
need for additional relays or remote inputs.
The ‘Q485’ also acts as an electrical barrier
between the compressor and the Conductor 4
providing protection and voltage isolation.
3.5.1 Input Functions
The ‘Q485’ is fitted with a six-pin terminal C04
for compressor monitoring. The ‘Q485’ uses
two inputs (Ready and Run) to determine
compressor status. An Alarm input can be
used if compressor alarm indication is
available and required. The Alarm input is
optional and is not necessary for system
operation.

The ‘Q485’ is a DIN rail mountable module
designed to be installed within the compressor
control or switchgear area.
Each 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 a remote
load/unload control with the ability to accept a
volt-free switching contact input for remote
load/unload.
Consult the air compressor manual or your
air compressor supplier/specialist for details
before installing the Conductor 4.

C04
READY
The READY input will accept 12V to 250V ac
(50/60Hz) or dc.
Do not connect a voltage greater than
250Vac/dc to this input.
This input must be connected to the terminals
of a ‘ready’ or ‘operational’ lamp, or other
circuit of the compressor control system, that
will be energised when the compressor is in a
started (standby or running) condition.
The voltage to this input must de-energise
when the compressor is stopped and
unavailable to produce air upon a load signal,
or the Emergency Stop button is pressed, or
when the compressor experiences a fault that
prevents the compressor from running.
Net$ync II Conductor 4
When the compressor ready lamp, or other
control circuit, is energised the ‘Q485’ will
detect the voltage and signal the Conductor 4 that
the compressor is ready and available to load and
produce air when a load request signal is
given.

The ‘Q485’ input common terminal must
always be connected to the neutral, common

Ready Input, Alternative Connection Method:
In instances where a convenient voltage signal
for a compressor ready condition is not
available the ‘Ready’ input can be connected
directly to a constant compressor control
system power supply voltage (12V to 250Vac
or dc). This will signal the Conductor 4 that the
compressor is ready and available at all times
when power is applied to the compressor. The
Conductor 4 has a built-in function to determine
when a compressor is not responding, or is in a
shutdown condition, regardless of a constant
ready signal. If the Conductor 4 requests a compressor
to run/load, but fails to detect a RUN signal
within 60 seconds, the Conductor 4 will regard the
compressor as ‘not ready’ and indicate the
compressor as not available. If a RUN signal
is detected at any time, the Conductor 4 will
automatically reset the compressor ‘not ready’
condition and re-establish control.

12V to 250Vac must be applied to the ‘Run’
terminals when the compressor motor is
running.
This input can be connected to the control
terminals A1 and A2 (coil) of the main starter
contactor of the compressor. When the
compressor control system energises the main
contactor, the ‘Q485’ will detect the voltage
across the contactor coil terminals and signal
the Conductor 4 that the compressor is running.
Alternatively, if the main contactor coil voltage
is greater than 250Vac, a contactor auxiliary
switch can be used to apply a suitable voltage
to the ‘Run’ input terminals.

The C01 and C02 terminal functions of the ‘Q485’
are intended to control load and unload
regulation of the compressor.
Pressure Switch Regulation:
For air compressors fitted with an electromechanical
pressure switch a six-pin terminal
C02 has been provided to enable connection
to a pressure switch that has a two wire or
three-wire connection.
When connected the pressure switch can be
switched in and out of circuit automatically. If
the Conductor 4 is stopped or experiences a
failure or loss of power, pressure control will
automatically revert back to the pressure
switch and the compressor will continue to
operate in ‘Local’ mode.
The local pressure settings of all
compressors in the system should be set in a
cascaded manner such that the system will
operate normally in the event of Conductor 4
inoperability.
Net$ync II Conductor 4
The NC (normally closed) and NO
(normally open) terminal references of the ‘Q485’
are related to internal connection
functions and should not be referenced to the
connections of a compressor pressure switch;
which will generally be in reverse order.
Remote Load/Unload Regulation:
Lethal voltages may be present on the
terminals of the air compressor pressure
switch. Isolate the air compressor power
supply before starting any work.
This terminal provides volt free contact closure
for load control and also provides volt free
contact closure for remote pressure control
enable.
Two Wire Pressure Switch Connections:
A remote load enable input provides the facility
to change the compressor load regulation from
internal control to a remote switching source.
For air compressors controllers fitted with
‘Remote/Local Pressure Regulation’ digital
inputs, a 4-pin connector C01 has been
provided.
Note: Compressors that use electronic
pressure detection but are not equipped with a
remote pressure control enable feature will not
automatically revert to local control if the Conductor 4

‘Pressure Switch Control’ (terminal C02)
output connections at the same time for
different products. These two output functions
are internally connected and a short circuit
condition and/or malfunction may result.
The ‘Q485’ connection examples shown in
this manual are intended to provide a guide

Service Maintenance Switch:
The ‘Q485’ is equipped with a volt-free input
(terminal C05) that can be used to remove the
compressor from Conductor 4 control, without
generating a fault condition, during short-term
maintenance or servicing periods.

When the ‘Service Maintenance Switch’ input
terminal pins are connected together, using a
volt-free switching contact, the Conductor 4 will
indicate that the compressor is not available but
will not generate an Alarm, Trip or Shutdown
condition. The Conductor 4 will also remove the
compressor from the sequence strategy and
substitute with an alternative available
compressor if necessary. When the ‘Service
Maintenance Switch’ inputs are open circuit
again the compressor will automatically be
accepted back in to the sequence strategy and
will be utilised as and when next required.
The use of a ‘key switch’ is recommended for
this purpose in order to prevent the switch
contacts being inadvertently left in the closed
circuit condition after service maintenance is
complete.
DO NOT connect any external voltage
source to the pins of terminal C05.

RS485
RS485 data communications and other
low voltage signals can be subject to electrical
interference. This potential can result in
intermittent malfunction or anomaly that is
difficult to diagnose. To avoid this possibility
always use earth shielded cables, securely
bonded to a known good earth at one end. In
addition, give careful consideration to cable
routing during installation.
a) Never route an RS485 data
communications or low voltage signal cable
alongside a high voltage or 3-phase power
supply cable. If it is necessary to cross the
path of a power supply cable(s), always cross
at a right angle.
b) If it is necessary to follow the route of power
supply cables for a short distance (for
example: from a compressor Conductor 4 to a
wall along a suspended cable tray) attach the
RS485 or signal cable on the outside of an
earthed cable tray such that the cable tray
forms an earthed electrical interference shield.
c) Where possible, never route an RS485 or
signal cable near to equipment or devices that
may be a source of electrical interference (for
example: 3-phase power supply transformer,
high voltage switchgear unit, frequency
inverter drive module, radio communications
antenna).

Pressure Sensor Offset
Pressure Sensor Range
Pressure Sensor Calibration Procedure:
1) Commissioning
Initially set the ‘Offset’ (minimum) to the
minimum or lowest pressure value for the
sensor. Set the ‘Range’ (maximum) to the
maximum or highest value for the sensor.
For example:
If the pressure sensor is a 0 to 16bar (0 to
232psi) type set the ‘offset’ to 0bar (0psi) and
the ‘Range’ to 16.0bar (232psi).
If the sensor is a –1.0(minus one bar.g) to
15.0bar type, set the ‘offset’ to –1.0bar (minus
one bar) and the range to 15.0bar.
Note: The ‘range’ value equates to the
maximum value not the scope of the sensor.
Execute the calibration procedure.
Page 30
a) Offset: Expose the sensor to atmosphere
and adjust the ‘offset’ setting (if necessary)
until the detected pressure display shows
0.0bar (0psi).
b) Range: Apply an accurately know pressure
to the pressure sensor and adjust the ‘Range’
setting until the detected pressure display
matches the applied pressure. An applied
pressure equal too, or greater than, the
nominal system working pressure is
recommended.
The detected pressure is displayed with the
calibration menu item and will change to
match the new calibration setting as the
setting is adjusted.
There is no need for the applied pressure
to be static; it can be dynamic and changing.
This enables calibration to be carried out on a
fully operational system where changing
system pressure can be accurately verified
from another source.
Correct pressure sensor set-up and
calibration is critical for successful system
operation. It is recommended that pressure
sensor calibration is examined, and adjusted if
necessary, annually or a pre-determined
routine periodic basis.

7.9 Stop:
To stop the Conductor 4 press Stop.
The Conductor 4 will respond dependant on
set-up: PC=0) Pressure regulation control is
automatically transferred back to each
compressor. The compressor(s) will continue
to operate using the pressure settings
programmed or set in the individual
compressor controller(s).
PC=1) The Conductor 4 will hold each compressor
in an offload state. If the compressor is equipped
with a main motor run-on-time function the
compressor will run offload for a period of time
and then stop in to a ‘standby’ or ‘auto restart’
state.
The design of some air compressor control
systems may inhibit automatic transfer of
pressure regulation control to local operation
mode. In this instance the compressor will not
continue production of compressed air –
consult the air compressor manual or your air
compressor supplier / specialist for details
before installing the Conductor 4.

If the Conductor 4 experiences a disruption to
normal control, or a Conductor 4 shutdown fault
occurs, pressure regulation control is automatically
transferred back to each compressor. The
compressor(s) will continue to operate using
the pressure settings programmed or set in
the individual compressor controller(s).
7.13 Reset
To reset a Conductor 4 Alarm (Warning) or
Shutdown condition press Reset.
Compressor Alarm (Warning) conditions are
automatically reset when the condition has
been resolved and reset on the compressor.
Compressor Not Available (Shutdown, Trip)
conditions are automatically reset when the
condition has been resolved and reset on the
compressor; and the compressor has been
restarted.

7.14 Fault Codes:
In the event of a unit or system ‘Fault’ the
Conductor 4 will display a fault code. The fault
code becomes an item in the User operational
display menu. If more than one ‘active’ fault
occurs each will be displayed as a separate
item in the operational User menu; press Up
or Down to view all active fault codes or to
view the normal status display.
Alarm (Warning)
Shutdown (Trip)
Fault codes are separated in to unit faults
‘ERR’ and system Alarms (Warning) ‘SYS’.
Each fault type has a unique numeric code.
ERR.01 ERR.04 Pressure Sensor
Compressor fault states are displayed as
part of the normal operational status display
and do not generate fault codes. Examine the
applicable compressor unit to establish the
nature or description of the detected fault
condition.
Special Controller Fault Codes:
E0836 PLL Unlock; Internal failure or
excessively high external
electrical interference
E0866 Controller internal power
supply fault
E5000 Internal memory map error
E5001 Internal memory failure
To Display the Software Version:
Press and hold Reset then press Escape.
The clock time display will change to show the
software version ID (example: “E01”).
