Net$ync II Conductor 12
2. INTRODUCTION
The EnergAir Metacentre Conductor 12 is a
specialised supervisory and control product
designed to provide energy efficient optimised
pressure and sequence management of up to 12 air
compressors operating on a common air
system. The EnergAir Metacentre Conductor 12
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.
As default the Conductor 12 is supplied with four
direct connect terminals and a data communications
network port enabling a further eight
compressors to be integrated using remote
integration modules. Further direct connect
terminals (up to a maximum of 12 in total) can
be added to the Conductor 12 using optional local direct
connect modules (iX Modules).
Consult the air compressor manual or your
air compressor supplier/specialist for details
before installing the Conductor 12 unit.
2.1 Compressor Connectivity
2.2 Pressure Detection and Control
Each air compressor in the system can be
integrated with the Conductor 12 using a number
of methods:
1) Two wire data communications; for
compressor controllers equipped with an
RS485 port utilising the Multi485 protocol
2) One of several optional integration units
designed to accommodate various types of
compressor and regulation methods.
3) Direct connect utilising 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 EnergAir Metacentre Conductor 12 utilises the signal
from an electronic pressure sensor that can be
mounted remotely from the Metacentre Conductor 12 in a
suitable location in the compressed air
system.
The direct connect
interface module (Q485) is
installed within the
compressor control area
and connected to the Conductor
12 using a six-wire cable.

As default the EnergAir Metacentre Conductor 12
is setup 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 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.

3. Features and Functions
3.1 Pressure Control:
The primary function of the Conductor 12’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 Conductor 12 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 12 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 12 (DA) is adjustable.
Net$ync II Conductor 12
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 12, 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 12 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 12 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 12’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 12 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 12’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
and remain fixed and unchanging. The

running as demand increases.
This is not an energy efficient focused
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 12
3.5 Sequence Control Strategies:
The Conductor 12 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 12 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 12 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 12’s compressor running hour’s menu.
The Conductor 12 uses these values in EHR mode.
The Conductor 12’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 12 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.
Page 7
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.
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 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.
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.

Energy Control Mode
The primary function of Energy Control mode
is achieving and maintaining demand matched
optimum system efficiency. Energy Control
mode can accommodate differential capacity,
variable capacity and variable speed air
compressor types in any combination or
configuration.
Control and Rotation:
Compressor control and utilisation is
dynamically automated and is not based on
pre-determined rotation configurations or time
intervals.
The system management unit is aware of
compressor capacity relationships and
variable capacity capabilities, where
applicable, and is able to dynamically
implement and continuously review ‘best fit’
configurations as demand variations occur.
The basic principle of the Energy Control
strategy is the efficient utilisation of available
resources matched to fluctuations in demand.

Tables:
PC
The Conductor 12 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 12.
The Conductor 12 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 12 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.
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 12 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.
Table Parameters:
Sequence Rotation:
Each table consists of the following
parameters; the parameters can be set
differently in each table.
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.
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 12 will
increase, or decrease, the pressure target
levels towards the new table settings in a
gradual transition over a period of time.
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.

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.

3.6 Priority Settings:
Priority settings can be used to modify the
‘Rotation’ sequence assignment. Compressors
can be assigned a ‘priority’ of 1 to 12; 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
Page 10
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

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.

3.7 Prefill:
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 12 will only load
compressors that have been pre-determined
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 12 will utilise as many available
compressors as required to achieve normal
operational pressure as quickly as possible.
Normal operational control will then begin.
Three prefill modes are available. ‘Backup’
and ‘Standard’ modes require compressor preselection
and function in the same way;
differing only in response to a failure, or loss,
of a prefill compressor. Automatic mode
requires no compressor pre-selection.
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, a pre-defined backup compressor
replaces it 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.
A Automatic Mode: No Prefill
compressor selection is necessary; any
selection set is ignored. The management unit
automatically selects compressor(s)
dynamically to achieve pressure in
accordance with the set Prefill time. If a
compressor is stopped, or shuts down, it is
automatically substituted with an alternative
compressor.
To manually skip Prefill mode, press and
hold Start for several seconds.

3.8 Pressure Schedule:
3.9 Insufficient Capacity Alarm
The Conductor 12 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 12 is wall mounting using
conventional screw fixings. The Conductor 12 can
be located remote from the compressors but within
100 m (330ft) cable length from each compressor
and within 100 m (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.
System (Demand Side) Pressure Control:

4.2 Power Supply
A fused switching isolator must be installed to
the main incoming power supply, external to
the Conductor 12. 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).

4.5 Compressor Interface PCB
The ‘Q485’ is designed to interface a
compressor with the Conductor 12 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
12 utilising an ‘Q485,’ the signal wires must be
connected to the Conductor 12 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 12
providing protection and voltage isolation.
4.5.1 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 12.
ALARM
RUN
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.
Page 15
Technical Manual
When the compressor ready lamp, or other
control circuit, is energised the ‘Q485’ will
detect the voltage and signal the Conductor 12 that
the compressor is ready and available to load and
produce air when a load request signal is
given.
Run Input:

The ‘Q485’ input common terminal must

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 12 that the
compressor is ready and available at all times
when power is applied to the compressor. The
Conductor 12 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 12 requests a
compressor to run/load, but fails to detect a RUN
signal within 60 seconds, the Conductor 12 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 12 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 12 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 ‘Q485’ input common terminal must
always be connected to the neutral, common
or 0V line of the applied input voltage.
Alarm Input (optional):
The ‘Q485’ is equipped with an alarm (or
warning) input that can be used to detect
alarm or warning conditions.
A fault, that stops the compressor, and/or
prevents the compressor from running, is
determined from the ‘Run’ and ‘Ready’ inputs;
Alarm detection is optional and is not a
requirement.
4.5.2 Output Functions
The Conductor 12 will control the ‘Q485’ load/
unload relay outputs in accordance with the active
system load and unload pressure set points.
The ‘Q485’ load/unload relay contacts can be
used for compressor controllers that have
‘pressure switch’ load/unload regulation.

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 12 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 12
inoperability.
Page 17
Technical Manual
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.

‘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
for the majority of compressor control
systems in use. Some compressors have
variations in operation and/or function;
consult your compressor
supplier/specialist for advice.
Service Maintenance Switch:
The ‘Q485’ is equipped with a volt-free input
(terminal C05) that can be used to remove the
compressor from Conductor 12 control, without
generating a fault condition, during short-term
maintenance or servicing periods.

C05
When the ‘Service Maintenance Switch’ input
terminal pins are connected together, using a
volt-free switching contact, the Conductor 12 will
indicate that the compressor is not available but
will not generate an Alarm, Trip or Shutdown
condition. The Conductor 12 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 12 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).

Access Code:
Display Item Structure:
Access to adjustable menu page items is
restricted by access code. To access menu
mode pages press MENU (or UP and DOWN
together); an access code entry display is
shown and the first code character will flash.
All operational system status and values are
accessible from the normal User display. To
view status or values, that are not normally
visible on the default screen, press UP or
DOWN. All standard User display items are
view only and cannot be adjusted. The
standard User display items are regarded as
‘Menu Page 00’ items.
All adjustable value, parameter or option item
displays are grouped into ‘menu mode’ lists.
Items are assigned to a list according to type
and classification. Item lists are identified by
page number (or menu number); All adjustable
parameters and options are assigned to menu
mode pages ‘P01’ or higher.
Normal Operational Display (Menu Page P00):
At controller initialisation, all LED indicators
are switched on for several seconds before
initialisation is complete and the normal
operating display (Page P00) is shown. In
normal operational display mode the main
display will continuously show the detected
system pressure and the Item display will
show the first item of the ‘Page 00’ 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
be shown. 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 and can be viewed by
pressing UP or DOWN. The most recent
‘active’ fault will be at the top of the list.
0000
Use UP(plus) or DOWN(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 Accepted
Access Code Rejected
Access Code Timeout:
When in menu mode, if no key activity is
detected for a period of time the access code
is cancelled and the display will automatically
reset to the normal operational display.
Menu Mode Navigation:
In menu mode the menu ‘page’ number will be
highlighted at the top of the display.
P00
To select a menu ‘page’ press UP or DOWN.
To enter the highlighted menu ‘page’ press
ENTER; the first item of the menu ‘page’ will
be highlighted. Press UP or DOWN to scroll
though the selected menu ‘page’ items.
Page 23

Some menu items may consist of several
individual settings. Each setting of the menu
item is also referenced as a sub-item number.
For example: P01-01.02 references sub-item
‘02’ of menu item ‘01’ in menu page ‘P01’.
Sub-item settings, where applicable, are
always displayed together on the same ‘Item’
adjustment display screen. Most menu items
are single value or single option only in which
case the single item is referenced as sub-item
number ‘01’ (for example: P01-01.01).

Press and hold RESET for several
seconds at any time to immediately exit menu
mode and return to the normal operational
display. Any value or option adjustment that
has not been confirmed and entered into
memory will be abandoned and the original
setting maintained.
The Conductor 12 will retain an ‘access code’ for a
short period after menu exit allowing the menu
structure to be re-entered without the need to
re-enter the access code again. To
immediately clear access code retention press
and hold RESET for several seconds.
A ‘locked’ symbol displayed with any item
indicates the item is locked and cannot be
modified. This will occur if the Item is view only
(not adjustable) or in instances where the item
cannot be adjusted while the Conductor 12 is in an
operational state; stop the Conductor 12 first.

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).
Page 31
Technical Manual
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.
C02 - 01
to
C02 – ‘n’
C03 01.01
a) Offset: Expose the sensor to atmosphere
and adjust the ‘offset’ setting (if necessary)
until the detected pressure display shows
0.0bar (0psi).
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.

Compressor Start Time:
Set to match the time that the compressor
takes to start it’s main motor and load. This
time will typically be equivalent to the
compressors ‘Star/Delta’ time. If unknown, the
time can be established by experiment;
manually start the compressor, from a stopped
condition, and determine the time from
pressing the start button until the compressor
loads and contributes capacity output to the
system.
This time is used by the Conductor 12 for
‘staggered starting’ of multiple compressors and
other operational calculations. An accurate time is
important for successful Conductor 12 operation.

with 100% capacity. Equal capacity (equal
sized) compressors should be assigned the
same % capacity value.
Only applicable for a variable output
compressor (V-485).
For example:
The percentage value is directly related, and
scaled, to the maximum and minimum output
percentage values.

% Minimum Output Capacity
Only applicable for a variable output
compressor (V-485).
The minimum output capacity of a variable
output compressor must be set as a
percentage of the compressor’s maximum
output scaled in accordance with the %
maximum capacity output value. Minimum
output capacity is regarded as the output
capacity at the lowest possible speed (variable
speed compressor) or the minimal output
achievable (stepping or other variable
regulation control compressor).
For example 1:
For a variable speed compressor that has
been assigned a maximum capacity output
percentage of 100%, and is able to reduce
speed to 50% of maximum speed:
Minimum Output Capacity = 50%
For example 2:
For a variable speed compressor that has
been assigned a maximum capacity output
percentage of 50%, and is able to reduce
speed to 50% of maximum speed:
Minimum Output Capacity = 25%
The minimum efficiency point is regarded as
the speed, or step, below which another
smaller capacity compressor in the system
could achieve the equivalent output at a higher
efficiency.
For example:
For a variable speed compressor that is able
to reduce speed to 50% of full speed, which
has been assigned a maximum output
capacity of 50% and a minimum output
capacity of 25%.
If another compressor in the system is able to
provide 60% of the compressor’s full speed
output more efficiently, set the % Minimum
Efficiency value to 30%. This percentage value
represents 60% of the full speed output of the
compressor.
When the compressor is detected as operating
below the % Minimum Efficiency value the
system management unit will re-evaluate
utilisation and re-configure, if possible, to
utilise a smaller capacity compressor, or
combination of compressors. This process is
automatic and executed dynamically in
accordance with prevailing operational
conditions at the time.
The intent of this feature is to prevent a
variable output capacity compressor operating
at minimal speed, or minimal output, for
prolonged periods of time. Generally a variable
output compressor operating at minimal
capacity is less efficient than a smaller
capacity compressor that is able to achieve
the same output at higher, or maximum, output
capacity.
For example 3:
For a 3-step (0/50/100) reciprocating
compressor that has been assigned a
maximum capacity output percentage of 60%,
the minimum output capacity is the half-output
regulation step:
Minimum Output Capacity = 30%

To stop the Conductor 12 press Stop.
The Conductor 12 will respond dependant on the
setup of item ‘CF’ in menu S02:
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).
The Conductor 12 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 12.
7.11 Start:
Each compressor in the system must be
started (running or in a standby or auto restart
condition) before Conductor 12 control of the compressor
can be established. The Conductor 12 will not start a
compressor that is in a stopped condition.
7.12 Power Failure Auto-Restart
If the power failure auto-restart function is
enabled the Conductor 12 will automatically start,
when power is restored after a disruption or failure, if
the Conductor 12 was in a ‘started’ state when the
power disruption or failure occurred.
The Conductor 12 will not automatically restart
if the Conductor 12 was in a stopped state when the
power disruption or failure occurred.
7.13 Failure Mode
If the Conductor 12 experiences a disruption to
normal control, or an Conductor 12 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).
To start the Conductor 12 press Start.
If the ‘Start Function’ is enabled there will be a
period of time before any compressor is
requested to load.

The Fault LED will ‘fast flash’ to indicate a Trip
(Shutdown) condition. A Trip (Shutdown)
condition will stop normal operation of the Conductor
12. Pressure regulation control will automatically
revert to the individual compressors that will
continue to operate using the pressure settings
for their own control systems. All Trip
(Shutdown) conditions are registered in the Conductor
12 Error Log. All Trip (Shutdown) conditions must
be manually reset.
Fault Codes:
Each individual fault has a unique numeric
code.
ERR.01
Pressure Sensor Fault
The signal from the control pressure sensor is
out-of-range (<3.5mA or >21.8mA).
Fault codes are separated in to unit faults
‘ERR’ and system Alarms (Warning) ‘SYS’.
ERR.04
Internal 24V Fault
The 24VDC power supply, internal to the unit’s
controller, is below 19.2V (internal controller
fault)
ERR: Unit faults are errors with the Conductor 12
controller itself and are all conditions that
prevent normal operation from continuing.
SYS: System faults are items that arise from
conditions external to the Conductor 12 controller;
the Conductor 12 itself continues to function correctly.
ERR.05
Emergency Stop
The wire link between terminals ‘+C’ and ‘C1’
of the unit’s controller is open circuit. These
terminals are permanently connected together
on the SX Terminal PCB: this error will never
occur in normal operational circumstances.
There are two types of Fault condition:
ERR.06
Real Time Clock Error
The Real Time Clock device, internal to the
unit’s controller, has failed.
Alarm (Warning):
1sec
The Fault LED will ‘slow flash’ to indicate an
Alarm (Warning) condition. An Alarm
(Warning) indicates that the Conductor 12 is
continuing with normal operation but user attention is
required. All Alarm (Warning) conditions are
registered in the Conductor 12 Error Log. All Alarm
(Warning) conditions must be manually reset.

Internal Controller Fault ‘E’ Codes:
‘E’ code errors are specific to the unit’s
‘internal to controller’ digital logic circuits and
will only occur in the most exceptional of
circumstances.
All ‘E’ code conditions are Trip
(Shutdown) type faults. The ‘Fault’ (red) LED
will ‘fast flash’ and the condition is registered in
the Error Log. If an ‘E’ code fault condition
persists, consult your product supplier for
advise or renew the unit’s controller.
E0836: PLL Unlock; Internal failure or
excessively high external electrical
interference detected.
The main timing circuit (processor clock) has
been disrupted and the processor is running
on an ‘internal to chip’ back-up clock.
The back-up clock is intended to keep the
processor running, at a much slower
processing speed, to enable emergency
actions to be taken. The controller is unable to
continue running the main software application
in this condition.
The unit will Shutdown; compressors will
continue to operate using local pressure
regulation.
The controller’s main power supply must be
removed and re-applied to reset this condition.
E0866: Controller internal power supply fault
The low voltage logic processing power
supply, internal to the unit’s controller, is below
minimum operational levels; internal to
controller fault. Renew the controller if this
fault condition persists. The Trip must be
manually reset from the keypad.
E5000: Internal memory map error
The unit’s controller has detected disruption to
the internal operational memory storage
(RAM). The integrity of the RAM memory
contents are suspect; the controller must be
reset to clear and re-map the memory. Renew
the controller if this fault condition persists.
The controller’s main power supply must be
removed and re-applied to reset this condition.
E5001: Internal memory failure
The unit’s controller has detected disruption to
the internal permanent application memory
storage (FLASH). The integrity of the FLASH
memory contents is suspect. Re-load the main
application software in the first instance; renew
the controller if the condition persists.
The controller’s main power supply must be
removed and re-applied to reset this condition.
