TRANSMITTER
1.0 GENERAL
The KOS215 is a universal DIN Rail mounted temperature transmitter that accepts
most commonly used temperature sensors, slide wire transducers or mV signals and
transmits them as a 4-20mA signal to a host system. The unit can be programmed by
the user from a selection of preset ranges selected by DIL switches or by computer if
required.

3.0 INSTALLATION
3.1 Mechanical
The transmitter is designed to mount onto a standard Din Rail. The transmitter should
be installed with adequate protection from moisture and corrosive atmospheres. The
transmittermay be mountedin any orientation.
Care must be taken when locating the transmitter to ensure the ambient temperature
remains within the specified operating rang. The figure shows the mechanical layout of
thetransmitter.

WARRANTY
The instruments are warranted against defective materials and
workmanship for a period of three years from date of delivery.
If a product appears to have a defect or fails during the normal use
within the warranty period, please contact the distributor from which
you purchased the product.
This warranty does not apply to defects resulting from action of the
buyer such as mishandling or improper interfacing.
The liability under this warranty shall extend only to the repair of the
instrument. No responsability is assumed by the manufacturer for
any damage which may result from its use.

3.2 Electrical
Connections to the transmitter are made to the tension clamp terminals
providedon the frontface. Output signalwiring should usescreened
twisted pair. It is recommended that the screened cable is used for the
input signal wires for cable runs greater than one metre. For Pt100 inputs
all three input wires must have the same core diameter to maintain equal
resistance. If required the user may change the range of the transmitter by
selecting one of the ranges from the table shown in section 3.3. Power
must be switched OFF first. The selection switch is located at the rear of
the transmitter between the Din rail mounting.
The figure shows the method of connection to provide a 4-20mA current loop output.
The Pt100 sensor shown would normally take the form of a probe assembly with a
three wire connection. The output loop has a voltage power supply used to provide
loop excitation. The load symbol represents other equipment in the loop, normally
indicators, controllers or loggers. Care must be taken when designing the 4-20mA
circuit to ensure that the total voltage requirements of all the equipment in the loop
added together , does not exceed the power supply voltage. If a number of
instruments are connected in the loop, ensure that only one instrument is tied to
ground. Grounding the loop at two points will cause a short circuit of part of the loop
leading to measurement errors.
To maintain CE compliance the transmitter should be mounted in an enclosure to
prevent access to the transmitter during normal operation.

4. CONFIGURATION
The following transmitter parametres can be reconfigured by the user:
Units ºC, ºF, mV or %
Low Range Corresponds to 4mA output
High Range Corresponds to 20mA output
Tag Nº Transmitter identifier
Offset User calibration adjustement
Filter None, 2sec, 10sec, adaptive
Configuration of the trasnmitter is achieved by connecting a PC running RCPW
configuration software to the transmitter via the Configurator Unit. Range switch must
be set to all positions up before programming a non standard unit.

4.1 Connection of Configuration Module
When configuration is performed using an existing loop, the loop power must be
capable of supplying 30mA and the load resistor chosen so that at least 10V remains
across the transmitter, taking into account all other volt drops within the loop. The
configurator is connected by plugging the 3.5mm jack plug in to the socket located in
the front panel behind the transparent window.
4.2 PC Installation of RCPW
Minimum PC operating system: Windows3.1
Minimum PC requirement: IBM386 or above with 4Mb RAM and
available serial port.
To install RCPW, log File Manager on to drive A: (or as appropriate) and run the
installation program. Note: if no "Product License Number" is entered when prompted
the program will operate in Demonstration mode only.
4.3 Operation of RCPW
Theconfiguration software has alist of main menuoptions which are:File,
View, Option, Devices and Help. These options can be selected by the
mouse or by sinultaneously depressing <ALT> and the letter underlined
as above. Once a menu option has been selected, the status bar shows a
brief description of functions.
For more details see RCPW onscreen help.
