INTRODUCTION
Pakscan 3 is a complete field network control system from Rotork. With the addition of a wireless
(P3W) network the user now has the choice of proven current loop technology of the Pakscan IIE
system or the flexibility of a meshed wireless network. The P3W master station is supplied with a
P3W Coordinator module; this module is powered by the master station and facilitates the
communications between the master station and the wireless network. Most types of Rotork actuators
can be connected to a Pakscan current loop provided they are fitted with the necessary field unit.
Information on the respective actuator field units can be found in the appropriate manuals. In this
guide, the type of actuator is not considered, though reference is made to both the integral and IQ
actuator types of field unit. The type of field unit does not affect the setting up of the system. The IQ
and IQT range of actuators integrate fully with the wireless network. The network range can be
extended using a P3W Repeater module, this module is externally powered and it extends the network
range by receiving and retransmitting network messages. Other actuators or devices can be added to
the wireless network using a Pakscan 3 Wireless Modbus Adaptor (P3W WMA). This module is very
similar to the P3W Repeater, but has a RS-485 serial port for communication. The Pakscan 3 master
stations are delivered either as loose items for mounting by the user, or contained in an enclosure
provided by Rotork. The master station will generally be either a single unit, or a hot standby pair.
This manual provides a guide to setting up the Pakscan master, the various P3W Wireless modules,
the loop communications, wireless communications, and the host connections for the most commonly
found applications.

A master station fitted with the wired network only requires the PS720 module that fits in to the back
plane. A master station fitted with wireless requires a module to be fitted to the back plane (in option
1) and connected to this module, a P3W coordinator module (PS722).

One required for single channel master stations, two for hot standby
master stations. The P3W repeater (a device for extending the
range of wireless) and the P3W WMA look identical to this.

1. Mounting and Connecting the Master Station
Issue 06/15 Publication PUB059-002-00 9 of 136
1. MOUNTING AND CONNECTING THE MASTER STATION
The Pakscan 3 master station (single or hot standby) provides front access for all the user
connections, including power feed and the field network connections –either loop wires to the Current
Loop module (PS720) or network connection to the P3W coordinator (PS721 and PS722). The host
communication links use plug in D-type connectors for the serial communications and RJ45
connections for the Ethernet links.
The field wiring for the current loop, P3W coordinator and the master station alarms are taken
to screw terminals on plug in connectors that are fitted from below their appropriate module.
Power wiring is connected using an IEC connector in the bottom of the master station module
PS710. Two connections are required for a hot standby system.
Serial communications (RS-232 or RS-485) plug into 9 way female D-type connectors on the
front of the mounting chassis.
Ethernet connections use RJ45 connectors on the bottom of the master station module
PS710. The connector on the front is intended for connection to a service laptop computer.
1.1 Mechanical Fixing
Room should be left around the module for all the connections and cables, allowing for a suitable
bending radius on each lead. Power wiring should be suitably fused or protected with miniature circuit
breakers (MCBs) external to the master station.
The master station may be mounted on a flat surface using the mounting brackets provided. Also, the
extension brackets allow it to be mounted in a 19-inch rack. In either case it should be located in a
way that permits easy access to the pushbuttons and easy viewing of the display panel(s).
Before mounting the master station, set the communications link
switches, as discussed in section 3.

1.2 Host Serial Communications Connections
The serial data connections are via the D-type connectors below each master station PS710 on the
main chassis. They are labelled Port 1 and Port 2 on both the A and B (left and right) sides of the
assembly. All the connectors are 9 way female and they may be set for RS-485 (2-wire) or RS-232
use. On hot standby systems they can be cross coupled to provide seamless communication when the
systems change over. The pin-out connections are shown below.
With RS-485 it is possible to arrange a multi-drop data highway for the serial communications,
whilst RS-232 must be single point communications.
1.3 Ethernet Communications Connections
Each Pakscan P3 CPU module (master station module) has 2 x RJ45 Ethernet connectors for the two
host communication ports (accessed from below) marked Port 3 and Port 4. A third RJ45 connector is
located on the front of each module. This is provided to allow a portable computer (laptop) to be
connected for diagnostic and set up purposes. Standard Ethernet patch cables can be used with these
connectors.
All Ethernet cables must be screened, and of good quality. Many screened Ethernet cables of low
quality have questionable screening efficacy.
All Ethernet ports on the master station have LEDs to indicate communication. Green indicates 10M
bit/s and orange indicates 100Mbit/s. Communication may be half duplex or full duplex.
1.4 Power Connector and Fuses
Each Pakscan P3 CPU module has its own internal power supply. A standard IEC connector is
provided to allow the mains power (85 to 263V AC –47 to 63 Hz) to be connected from below the
module. The mains IEC socket also includes the two fuses for the system, which must only be
replaced with the same and rating 250V 1A 5x20mm anti-surge fuses.

For the 24V DC version, a three pin removable screw terminal connector is provided. There is no
internal fuse.
1.5 Alarm and Hardwired ESD Connector
There is a removable screw terminal connector in each Pakscan P3 CPU module for the connection of
ESD hard-wired inputs and for connection to the internal alarm relay contacts, when required. On most
systems these terminals will not be used; in which case a hard-wired link between pins 4 and 5 must
be fitted, this is usually fitted by the factory.
Note the relay is shown in the ‘alarm active’ or ‘power removed’ position. The Alarm relay will activate
if there are any alarm conditions in any field unit or the master station. This alarm will not prevent
operation of the master station.
1.6 Current Loop Connections
A connector is located in the bottom of the key switch module on hot standby Pakscan 3 systems for
the connection of the current loop to the field mounted actuators. On single P3 master stations the
connector beneath the current loop module itself should be used.

1.7 P3W Coordinator Connections
A connector is located in the bottom of the (PS721) wireless option module to connect to the P3W
coordinator (PS722). The connection between these should be made using a shielded network cable
with 3 pairs of wires –each pair to be twisted. Suitable cable conforms to the specification for RS-422
networks. This cable can be up to 200m long so that the P3W coordinator may be mounted, for
example, on the roof of the building containing the master station.
The Communications cable and appropriate glands for the P3W coordinator will need to be sourced
locally, according to site requirements. Connect the Communications cable as shown below, noting
that the connections are NOT all one to one.

1.8 P3W Repeater and P3W WMA AC Power Connections
The P3W Repeater AC and the P3W WMA AC will contain a power module for the appropriate power
supply requested by the user. The power module is mounted the base half of the module with the
wireless module in the other half, the modules will be connected together by an interconnecting loom,
connected to SK1 on the power module and SK3A on the wireless module. The mains AC
connections are made to the power module connections L1, L2 and L3, shown in the Figure below.
The mains cable will need to be terminated in 4 mm ring crimps.
SK1, a flying lead, will be fitted by the factory to the appropriate tapping for the power supply that the
customer has indicated will be used. Fitting to the posts labelled W, X, Y and Z selects the correct
voltage. This should be checked for correct fitment before power is applied.
A switch or circuit breaker must be included in the wiring installations. The switch or circuit breaker
must be mounted as close to the module as possible and shall be marked to indicate that it is the
disconnect device for that particular module. The Power cable and appropriate glands for the P3W
coordinator will need to be sourced locally, according to site requirements.
Power supply: 3 Phase up to nominal 690V, 50 or 60Hz or
Single Phase up to nominal 230V, 50 or 60 Hz.
Check that the supply voltage agrees with that stated on the nameplate.
Power should only be applied with the module fully assembled i.e. the base
and the cover connected together with the bolts supplied.
Cable glands used must be appropriate to the classification of the area.
Conduit seals must be installed at the enclosure.

SK2 is the Modbus connection.
U1 is the cable screen clamp.
SK7 is the loom for the Wireless pcb.
FS1 is a 250 mA S500 fuse.
FS2 is a 100mA TDC11 fuse.
The wire attached to SK11 should be
attached by one of the pcb mounting
screws to the casing.

1.9 P3W Repeater and P3W WMA 24VDC Connections
The P3W WMA DC may be powered from the Modbus device to which it is connected, assuming the
device has the appropriate DC supply available. Under this circumstance the interconnection cable
between the device and the P3W WMA-DC should contain 2 shielded pairs, one for power supply and
one for the communication signal. In this case, the distance between the Modbus device and the P3W
WMA-DC should not exceed 10 meters.
The P3W repeater DC may also be powered from an external DC supply in the same way.
Connect the power cable as shown below, the connector labelled SK3A is used on the P3W WMA-DC
and P3W repeater-DC.
The power supply should be nominally 24volts (range 9-35volts, suggested power supply current
capabilities –200mA)

1.10 P3W WMA Modbus Connections
The P3W WMA connects to a Modbus RTU device enabling a Modbus host to connect through the
Pakscan wireless system to the Modbus device. The connection between the Modbus device and the
P3W WMA should be made using a shielded network cable with 1 twisted pair of wires. Suitable cable
conforms to the specification for RS-485 networks. This cable length will depend on the baud rate
chosen for communications.
The Communications cable and appropriate glands for the P3W coordinator will need to be sourced
locally, according to site requirements. Connect the Communications cable as shown below, the
connector labelled SK3A is used on the P3W WMA.

1.11 Setting up the P3W Repeater and P3W WMA
The P3W Repeater requires the PAN ID (Personal Area Network Identification number) and RF
Channel to be set up for the network to which it is attached. The P3W WMA also requires these
parameters and its Modbus communication parameters to be set up. This is achieved using the
Modbus interface that is available on both modules.
The Modbus physical connections are detailed in the previous section ‘P3W WMA (Wireless Modbus
Adapter) Modbus Connections’. For the purpose of configuration, these connections can be
temporary, for example, it may be more convenient to make the configuration changes in a workshop
before installation on site. For both devices it is likely that configuration is only required once,
therefore after installation there should be no need to access the Modbus connections again on the
P3W repeater.
During configuration in a workshop environment, the 2 halves of the module can be separated, such
that the Wireless module is disconnected from its power supply module. The wireless module can
then be powered, separately, using a 24VDC source as described in the previous section ‘P3W WMA
(Wireless Modbus Adapter) 24VDC Connections’.
For making configuration changes to the P3W Repeater or P3W WMA, there is a fixed Configuration
Modbus address of 248.
The P3W Repeater, requires the PAN ID and RF Channel to be set up, and if there are multiple P3W
repeaters the Modbus slave address must be set up such that all P3W repeaters are unique and can
appear as separate nodes on the wireless network.
The P3W WMA requires the Modbus communication parameters (baud rate and parity) to be set up,
as appropriate for communicating to the Modbus slave device it is to be connected to. The Modbus
slave device address is not required to be set up within the P3W WMA, as it will automatically scan for
attached devices using the baud rate and parity set. Up to 10 slave Modbus devices can be
connected, each device will require a unique Modbus address, within the range 201 to 247. The
address must be unique for the host device to be able to access it. Within the master station
configuration pages, the Modbus addresses used for the devices fitted to the P3W WMAs are required
to be selected. See section 7.5.17 master station configuration.
Changes to RF communication parameters will take place immediately. Changes to Modbus
communication parameters will take effect after a power cycle.
