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.

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
Figure 3: Junction Box Connections for a 3 Dryer Network.

4.4. Remote Communications Enclosure
The enclosure contains a local power supply, mains voltage input terminals,
a 9-way connector interface and an Active Network Interface (ANI). Which are
described below:
4.4.1 Power Supply
The power supply provides a stable DC voltage for the ANI.
The power supply requires connecting to an external fused mains supply of
between 85 - 264V 50/60Hz rated at 5W. The enclosure must be earthed; all
wiring must be in accordance with the latest edition IEE regulations or
equivalent local standards.
The connections to the input terminals are shown in Figure 4.
L - Live
N - Neutral
E - Earth / Ground
Figure 4: Remote Communication Enclosure - Mains Voltage Connection
4.4.2 Active Network Interface (ANI)
The ANI provides an interface between the PC and the RS485 dryer network.
The ANI sends messages to and receives messages from the DDE server
across one of the PC’s standard RS232 communication ports, it also sends
messages to and receives data from the nodes across the RS485 network.
9

On the ANI, there are multiple RS485 and RS232 ports. Ensure the connections
are made only to the communication ports specified below.
Figure 5: Active Network Interface (ANI) Terminals
4.4.3 RS 485 Connection
The RS485 cable from the junction box or dryer should be fed into the Remote
Communication Enclosure via an unused cable gland.
The cable should terminate in ANI terminal X02 and should be connected as
detailed in Table 1.
ANI Termination – X02 Dryer Plug Termination
X02 – 1 (L1) L terminal (RS 485/ L1)
X02 – 2 (L2) N terminal (RS 485/ L2)
X02 – 3 (Ground/ Earth) E terminal (RS 485/ screen)
Table 1:ANI Cable Terminations – RS 485 Connection
4.4.4 RS232 Connection
The Remote Communications Enclosure is provided with a 5-metre RS232
communication cable already fitted. If required the RS232 cable can be
extended to a maximum of 20m
N.B.Consideration should be given to network connections when
choosing a mounting position for the Remote Communications Enclosure.
The enclosure is rated to IP65/ NEMA 4 and should be placed in a
sheltered, indoor location.

4.5 Dryer Setup.
Up to 31 PNEUDRI electronic MPXE / DXE / DHE / MXA / MPXA dryers
(nodes) can be connected to a single RS485 network.
To remotely address each dryer, every dryer has to have a unique
Machine Number.
The default setting on dryers is “1”. This must be altered at commissioning by a
domnick hunter authorised service agent. The Machine Number can be
viewed via the front panel of the dryer under the SHOW SETTINGS MENU.
(Pneudri Electronic) or page 2#12 (MXA / MPXA)
Note: the dryer type and software type for each network member.
4.5.1 Pneudri Electronic
Inside the dryer shroud there is a white enclosure containing the controller.
Each dryer is fitted with a 2 position key switch, which can be set to either
Local or Remote.
When the switch is set to Remote this enables all the remote commands which
include the ability for the dryer to be remotely stopped and started and the
operation of the Automatic Bypass Valve to be changed.
When the switch is set to Local, all the remote command instructions are
blocked except for the “EnergyReset” command, which does not affect the
operation of the dryer.
This feature has been included so during service operations the dryer can still
be on-line and working to allow fault finding procedures. The Local switch
setting will inhibit certain remote commands, which could be potentially
dangerous for service personnel when working on units such as “START” and
or instance.
4.5.2 Pneudri MXA
No key switch is provided on MXA products but the option is included in the
customer menu 5#13. The functionality of the option is exactly as explained
above.

5.4 Software Setup
5.4.1 Site Specific Informaion
Before using the software it is necessary to finalise the site-specific settings this
is most easily achieved by using “Windows Explorer” and locating the “Multi
485” directory on the hard drive.
The “Multi 485” directory created is made up of a program executable
<Multi485.exe> file and 3 sub-directories each containing a system
configuration file. The “Multi 485” directory structure is shown below:-
\Multi485\
Code
Node
Station
multi485.exe
5.4.2 Code Sub-directory
The “Code” sub-directory is where the Code file should reside. Note: a separate
code file is required for each dryer or software version.
Pneudri Electronic version 3.3 dryer require the DHPNDRL1V3_3.cod file.
Pneudri Electronic version 3.5 dryers require the DHPNDRL1V3_5.cod file.
MXA dryers will require the R1DHPNEU_V01.cod file. These are present on the
disk supplied. These files must be manually copied into the Code sub-directory
on the hard drive. This file describes the DDE text strings, which should be
entered to obtain particular items of information from a node.
5.4.3 Node Sub-directory
The “Node” sub-directory is where the Node file should reside. Note: a separate
node file is required for each dryer / software version. Software version 3.3
dryers require the DHPNDRL1V3.3nod file. Software version 3.5 dryers require
the DHPNDRL1V3_5.nod file. MXA dryers require the R1DHPNEU_V01.nod
file. These are present on the disk supplied. This file must be manually copied
in to the Node sub-directory on the hard drive.
This file describes the DDE text strings, which should be entered to obtain
particular items of information from a node.

6 Using Remote Communication for the First Time
On the Windows “Start/Programs” taskbar will be a title for “Multi485 DDE
Server” which will lead to Multi485.
If no shortcut was created the file resides inside the Multi485 directory where it
can be started manually.
6.1 Multi485.exe
The <multi485.exe> file is the application file for remote communication. It also
provides a status report on network communications.
N.B. The <multi485.exe> file must be running to enable remote communication
with the network.
6.2 When Running For The First Time
Starting the <Multi485.exe> application will bring up a rectangular window on
the screen. “No Station Files or Corrupt Station File found: Add/delete file(s)!!
6.3 Enabling Communications For The First Time
Select “Stations” on the top menubar. This will lead to the “Station
Configuration/Selection” screen. Click the “Add Station” button. Browse to the
station directory CD drive. Select “Dryer-station.stn”. The relevant files will be
copied from the CD. Returning to the “Station Configuration/Selection” window
select “Dryer-Station” and click the Edit station file
The contents of the station file will be displayed. By default the station file is
setup for 31 dryers of Pneudri Electronic dryers all fitted with software version
3.5.
Edit the file and enter the information about each dryer i.e. machine number
and appropiate node file.
The only changes required to the station file will concern Pneudri Electronic
dryers V3.3 or MXA.
Example: Using the 3 dryer network shown in Figure 1.
The station file corresponding to dryers 2 & 3 requires alteration where 3_5
requires changing to 3_3.
14

i.e.
ITEMFILE: DHPNDRL1V3_5.NOD
becomes
ITEMFILE: DHPNDRL1V3_3.NOD
or
ITEMFILE: R1DHPNEU_V01.nod
Make this change to all dryers on the network. Save this file.
Returning to the "Station configuration/selection" window select "DRYER
STATION" and click "Set current station" then "Save on exit" then "Exit".
This will return to the main "Multi485" window where the message "Network
conversations are enabled" should be displayed.
Open Connections [topics]:
The number of nodes communicating via the ANI is displayed.
Current station:
The name of the current station file is displayed. The station file is selected
via the “Stations” drop down menu.
Messages received:
The number of messages received during the current running of the
<multi485.exe> file is displayed.
Open advise loops:
An advise loop is opened when the Adv command is entered in front of
certain DDE text strings. In these instances the node controller will automatically
advise the DDE server when that item has changed value or state.
Number of requests:
The number of requests for information sent by the DDE server during the
current running of the <multi485.exe> file is displayed.
Failed requests:
The number of failed requests for information sent by the DDE server during the
current running of the <multi485.exe> file is displayed. If the DDE server
continually returns failed requests, the problem is likely to be power supply (no
power to the ANI or the node) or wiring (break in the cable) related.
15

7 Addressing A Particular Node
An individual node can be addressed through packages supporting DDE.
For example, in Microsoft Excel, this is done by entering the command/request in the
format shown below:
=multi485|<DDENAME>!<DDE text string>
Therefore, if we want to read the sizing dewpoint of dryer #1 (machine number 1) then
we would enter the following: -
=multi485|dryer1!GetSizingDewpoint
8 Dryer DDE Commands
The "NODE" sub-directory contains the <DHPNDRL1V3_5.nod>,
<DHPNDRL1V3_3.nod> and <R1DHPNEU_V01.nod> system configuration files.
These files describe the DDE text strings which should be entered to obtain particular
information from a node.
For version 3.3 dryers a listing of the DDE names can be found in <DHPN
DRL1V3_3.nod> which can be printed out for reference.
For Pneudri Electronic version 3.5 dryers a listing of the DDE names can be found in
<DHPNDRL1V3_5.nod> which can be printed out for reference.
For MXA dryers a listing of the DDE names can be found in
<R1DHPNEU_V01.nod> which can be printed out for reference.
The list below gives generic information on the text strings to be entered to obtain
certain information from a PNEUDRI electronic MPXE / DXE / DHE dryer and a brief
description of each item. If you require further information on any item or MXA specific
commands refer to the Operating Manual for the dryer or the NOD file for the dryer
type in question.
N.B.The units for pressure and temperature/dewpoint values do not reflect the
true resolution of the associated sensors, this should be considered when
displaying the data.
