1. Introduction and Taking into Use
The PS power supply is designed for use with your moisture logger. It provides your meter with
electrical power and has a number of connectors for various user and process interfaces. In the
following find the proper use of each connector. For any details of use of the meter itself, refer to the
User's Guide.
PS is taken out of its package carefully and it should be inspected for any damage during shipping.
If any damage is visible, contact the manufacturer or the representative from which the unit was
bought. The following items should be available:
1. PS supply
2. User's guide (this)
3. Connection cables with connectors according to your meter
4. Wall supply cable with an IEC320 socket at one end
5. DIN rail mounting kit
6. Other optional items ordered
If something is missing, inform your dealer and he will ship any missing parts. The instrument is ready
for use after connecting the cables and power.
PS is a power supply giving 24 V 2 A continuously for your meter. It can supply 3 A temporarily for
starting the meter. Some power supplies are equipped with a 12 V output with double the current
capacity to better match requirements of the meter. The casing has a number of venting holes for
air circulation. The supply is intended for installation into either electrical cabinets or as an office
accessory.Ithas rubberfeetforcomfortabledesktopoperationtoo.Itisnotwatertightinanydegree
and should not be installed into such conditions where there is a risk of letting water inside. The supply
accepts any AC voltage between 85 and 240 Volts of 50/60 Hz. Also DC voltage is acceptable.
Check the unit's label for certifications and valid approvals. For wall power inlet, there is an IEC320
connector at one end of the supply. A suitable cable with the proper wall plug at the other end is
supplied. Minor variations may exist in this respect as conditions vary from country to country and the
plugs are often very different. There is also a cable fixed to the box which is for the moisture meter.
The other end of the cable carries either a Bulgin 8 pin connector (model A) or an ITT Cannon 12 pin
connector (model D). In some cases, there may be two of the Bulgin connectors and two cables,
especially if older moisture meter models are to be supported (model D). The rest of the cables for
various interfaces are to be connected to the specific connectors in the supply's box. This is
described in the following. Note that the power supply itself is identical for all models. Only the use
of each of these specific connectors may differ or the connector is not used at all. Also, the cables
and connectors are matched according to your meter model.
Connecting the Cables and Starting the Meter
Notice that the cable connectors in PS may have caps which protect them against dirt, depending
on the type of connector. The connectors are splash water proof. To keep them that way for the
operating life of the instrument and cables we ask the user to handle them carefully and to avoid
too much force while opening or closing. Else the sealing rings may be lost or threads or contact pins
may fail. Refer to Figures 1A to 1B for various cable connections in typical applications. In practice,
there are more possible combinations than these.
The cables are connected as follows. The Cannon 12 pin connector or Bulgin connector with 8 pins
go to the instrument socket. To separate the RS232/485 and Profibus DP cables from each other, they

are marked correspondingly. The DP cable has the standardized lilac colour bands at both ends. No
harm is done to the instrument if they are misconnected. The only problem will be that the
corresponding data communications do not operate.
The box has a D9 female connector for the PC serial cable (RS232 or RS485 for LAN) and another for
the Profibus DP. Note that to obtain the maximum operating speed 12 Mbauds for the RS485
termination should be correctly done at both ends of the cable. Also the intermediate cable should
be properly selected for high-speed operation. A twisted-pair cable with shielding is usually
sufficient. There are termination resistors available, one inside the meter and another inside the -PS.
Refer to the meter's own User's Guide for details and to Appendix 1 for finding the other. Sometimes
the DP D9 connector cases include a resistor with a switch which activates it. This is the easiest way
of testing for the need of the termination and of taking it into immediate use.

2. Basic Features of the Power Source Unit
Signals
The power source generates nominal 24 V 2 A for the meter for regular consumption. The
communication cable brings out the signals in analog and digital form and those signals are
distributed with the connectors at the front panel of the -PS. The serial port RS232 can be used for
direct connection to a PC or to a LAN232 unit which is used as a LAN for supporting the simultaneous
use of up to eight meters. The serial port can be configured as RS485 to be used as a wider LAN with
long legs (up to 1200 meters). The LAN232 can again be used here as the bridge to the PC after
configuring it to be a member of the RS485 network. The regular D9 female connector has been used
forthispurposeforsimplicity.Checkeachmeter'smanualstoseethebaudratesitiscapableofusing.
Note that using the highest baud rate 115200 bauds is possible only with rather short cables. If long
cables ( > 10 meters) is required, please use the lowest baud rate 9600 bauds for secured
communications.
The Profibus DP is a standardized fieldbus for mill automation and is capable of very high speed
operation. It is usually built up with a twisted-pair cable connecting each of the DP slaves and the
DP masters. The D9 female is used here on the front panel for direct acceptance to the DP network.
The meter's GSD file or equivalent information needs to be fed to the master before it tries to identify
the slave.
The analog signals (a voltage) are led to the BNC connectors on the front panel, marked as Signal
1 and 2. The first one is for the signal selectable as moisture, web temperature, head temperature,
expansion module or extra temperature signals. The meter's own scaling may affect this and the
basic voltage range can be selected as 0-10 V, +/-5 V or 0-5 V as selected in the meter. The second
channel is only available if the meter has the proper option.
The third BNC connector is for direct connection to the triggering input (TTL levels, falling edge
sensitive). A microswitch or some transistor (e.g. an optotransistor) can be directly connected to it.
The last D9 female connector is for applying either the SICK optical sensor module WT18-2P112 or
equivalent or some tailored sensor system. Refer to Appendix 2 for details.
There are two indicator lights on the front panel. The one marked as POWER indicates the presence
of 24 V at the cable end. The second one (CABLE SENSE) indicates the connection of the cable to
the meter. However, this indicator is active only in model D meters and only if you have either the
12-pin cable in use or you have both of the two 8-pin cables connected. The indicator is fed by the
isolated 5 V source from the meter and tells you that most likely the meter should be running OK.
A Note for AK40 Users
Please be aware that the meter AK40 does not have the Profibus DP but does have the analog
output of 4-20 mA for the moisture signal. It is scaled as 100 % / 20 mA and 0 % at 4 mA unless otherwise
noted. The signal comes out of the D9 female connector marked for DP (X1) and the pin ordering
is the following.
X1 pin original purpose signal
3 PB B 4-20 mA out active
8 PB A 4-20 mA return (ground)
You can connect this output to your DCS as an active source.
