1 Safety Warning
Refer to the Installation and Maintenance Manual, and the Operating Instructions
for the particular control system before carrying out any work on PNEUDRI
electronic MPXE / DXE / DHE / MXA / MPXA dryers.
When handling, operating or carrying out maintenance on a dryer or associated
equipment, personnel must employ safe engineering practices and observe all
relevant health and safety requirements and regulations. The attention of UK
users is drawn to the Health and Safety at Work Act 1974, and the Institute of
Electrical Engineers Regulations.
Most accidents, which occur during the operation and maintenance of machinery,
are the result of failure to observe basic safety rules and precautions. An
accident can often be avoiding by recognising a situation as potentially
hazardous.
Improper operation or maintenance of the dryer or associated equipment could
be dangerous and result in an accident causing injury or death.
domnick hunter can not anticipate every possible circumstance, which may
represent a potential hazard. The WARNINGS in this manual cover the most
common potential hazards and are therefore not all-inclusive. If the user employs
an operating procedure, an item of equipment or a method of working which is
not specifically recommended by domnick hunter he must ensure that the dryer
or associated equipment will not be damaged or made unsafe and that there is
no risk to persons or property.

2 General
The Remote Communication Package has been designed to operate on
PC’s within the Windows 95/98/2000/XP, NT 3.51/4 environment, utilising a
Dynamic Data Exchange (DDE) server. The use of DDE means that the data
can be easily transferred to other packages supporting DDE.
Upto 31 dryers can be integrated into a single system, and as with the dryers
themselves the Remote Communication Package is based on a modular
concept, where additional units can be added as the network grows.
The dryers are provided with an industry standard RS485 connection,
communications are therefore possible for networks up to 1200m in length.
The protocol used is a proprietry multi-master protocol, which means that
any dryer connected to the network can initiate communication. A dryer can
therefore advise the system if there is a problem without needing to be
asked.
Remote communication is only possible with PNEUDRI electronic
MPXE / DXE / DHE dryers operating with software version 3.3 or version
3.5 or MXA / MPXA dryers version 1.0 or higher.
Pneudri Electronic software version
Pneudri Electronic software version is displayed in the Inlet Temperature
Display at power up. PNEUDRI electronic Microprocessor upgrade kits are
available from domnick hunter, contact the Service Manager at domnick
hunter or your local domnick hunter distributor for further details.
Pneudri MXA software version
After switch on, for the first ten seconds of operation all the symbols are
initially displayed, then the software version is shown which is of the form
PA_E1.0 which corresponds to version 1.0.
IMPORTANT
A network consisting of both Pneudri Electronic Dryers and MXA dryers is
possible.

3. Remote Communication Package Scope of Supply.
The Remote Communication Package consists of the following components: -
i) Remote Communications Enclosure containing the Active Network Interface
(ANI) and local power supply.
ii) 5-metre RS232 communication cable;
iii) Multi485 DDE Server installation software
vii) Mating sockets for the RS485 connections on dryers.
(Seperate kit required for each dryer. Pneudri Electronic Units Only).
3.1 Exclusions
In addition to the above items, the following requirements, limitations and exclusions
should also be borne in mind: -
i) The domnick hunter DDE server has been designed to operate on a PC,
within a Windows 95/98/2000/XP or NT 3.51/4 environment. Windows 3.1 is
not supported.
N.B. The supply of the PC and Windows software is outside the domnick
hunter scope of supply; i.e. it is the responsibility of the plant operator.
N.B. The supply and installation of all wiring forming the RS485 communication
network between the dryers and the Remote Communications Enclosure is
outside the domnick hunter scope of supply, i.e. it is the responsibility of the
plant operator.

4. Hardware
4.1 General Arrangement
The general arrangement for a 3-bank PNEUDRI remote
communication installation is shown in Figure 1 below.
Figure 1: 3 Bank PNEUDRI Remote Communication Installation.
domnick hunter recommends that a single twisted pair of at least 0.5mm2
screened cable be used to connect the dryers to the Remote Communication
Enclosure. To ensure fitment through all glands the cable should be of circular
cross section and have a diameter between 3 and 6.5mm.
4.2.1 Dryer Cable Connections - Pneudri Electronic Units
Opening the dryer shroud, on the inside of the door will be a white enclosure.
The white control enclosure must have a 3-pin IP68 industrial chassis plug and
a 2-position key switch fitted to its upper surface, as shown in Figure 2 below.
The connector is the RS485 node termination and the key switch is the
Remote/Local control selector switch.

Figure 2: White Control Enclosure Detail
The plug is a Bulgin Buccaneer 3-pin IP68 industrial cable socket part number
PX0731S.
The socket should be terminated as follows: -
L terminal RS485/ L1
N terminal RS485/ L2
E terminal RS485/ screen
The cable can exit the dryer via an unused aperture in the black shroud
support, which will require the fitting of the cable gland which is supplied.
4.2.2 Dryer Cable Connection - MXA
At the rear of the dryer is the control box. Isolate the mains power and remove
the lid.
The controller label will show connectors X06 & X07. Although there is only one
connection port, it is split into two separate connectors for ease of “daisy
chaining”

MXA CONTROLLER

The screen can be terminated on the controller body by crimping into a 6.3mm
crimp terminal. It is suggested that only the controller end of the screen is
connected to earth.
4.3. RS485 Network/Junction Box (to be supplied by customer)
Depending on the dryer model and site specific conditions.
For ease of wiring and to retain the IP rating of the connectors at the dryer,
domnick hunter recommend that the connections on a multibank installation
should be brought back to a junction box. The “daisy chaining” inter-connections
can then be carried out in the junction box, which will allow ease of wire
identification and fault finding. The RS485 cable from each dryer should be
routed back to the junction box and terminated as shown in Figure 3. An
additional cable should be added which is then routed back to the Remote
Communications Enclosure.
NB: The maximum length of the dryer network cable must not exceed
1200m.
Pre assembled junction boxes can be purchased from domnick hunter,
contact the Service Manager at domnick hunter for further details
A typical connection diagram for a three dryer installation is shown in Figure 3
