TRACKER 300 SERIES PROCESS CONTROLLER INSTALLATION GUIDE 30-5012 ISSUE D
1. Introduction
The Tracker 300 provides solutions for the following applications:
• Data acquisition.
• Signal conditioning.
• Condition monitoring.
• Alarm trip.
•PIDcontrol.
2. Safety and EMC Information
Safety EN61010-1:2001
Susceptibility EN61326:1998
Emissions EN61326:1998
CE certified 2004
Warning: This instrument is marked with the international hazard
symbol. It is important to read this Installation Guide
before installing or commissioning the instrument as it
contains important information relating to safety and
Electromagnetic Compatibility EMC.
Warning: This instrument must be fitted within an enclosure that
provides adequate protection against electric shocks.
Warning: The mains terminals must use ferrules.
The unit is double insulated.
Note: Ensure that the power to the instrument is switched off before
carrying out any installation or maintenance work.
3. Installation
To install the instrument, you will need to carry out the following steps:
Make connections to the instrument as shown in Section 4 Connections.
1. Attach the instrument on a DIN rail.
To do this, latch the DIN rail recess on
the back of the instrument on the DIN
rail top runner.
2. Insert a screwdriver into the aperture
on the spring-loaded securing clip
located on the back of the instrument.
3. Lever the screwdriver upward to slide
the clip away from the instrument
(take care not to exert too much
pressure on the instrument casing).
Ensure the recess is located around
both the top and bottom DIN rail
runners then release the clip to
securely lock the instrument on the
DIN rail.
Note: •Avoid installing the instrument close to strong magnetic fields,
e.g. switch gear, contactors or motor starters.
•It is recommended that all connections to the terminals are
made using ferrules to provide greater reliability and to prevent
short circuits between adjacent terminals.
•Do not place signal and power supply wiring in the same loom.
•Use screened cables or wires for all signal/sensor leads with
the screen earthed at one end only.
•The DIN rail should be earthed to ensure the best performance
of the instrument.

5. Powering the Instrument
The AC mains supply version operates with voltages in the range 90-
230V≈@ 50/60Hz. The low voltage version operates from an AC/DC
supply in the range 10-32V .
The diagram shows how the instrument should be connected to the
appropriate supply. Isolation should be provided by a double pole switch
and a 630mA or 1A time-delay fuse as appropriate (see diagram below).
The isolation switch must be readily accessible.
Warning: This instrument is designed for installation in an enclosure
that provides adequate protection against electric shocks.
Access to power terminals should be restricted to authorised,
skilled personnel only. Application of supply voltages higher
than those for which the instrument is intended may
compromise safety and cause permanent damage.
Warning: Ensure the power supply is connected to the terminals
marked 3 & 4 as shown in the diagram above.
6. Indicators
There are two LEDs located on the front panel of the instrument, identified
as A and B as shown in the terminal connection arrangement diagram.
LED A – can represent four different functions:
1. When lit, it confirms that the instrument is receiving mains power.
2. When flashing fast (approx. 4Hz), it indicates that there is a
system error.
3. When flashing slowly (approximately 1 second per cycle), it
indicates that there is a process error, e.g. sensor break.
4. When flickering, it indicates that the serial communication
interface is transmitting.
LED B – functions are user programmable
7. Serial Communications
The instrument can be configured using either of its serial interfaces:
1. Connection to the RS485 interface is as shown below.
2. Connection to the front panel configuration socket is via a special
cable. The main RS485 interface is disconnected when the
configuration socket is in use.
There are no internal links or potentiometers. There is no reason to open
the instrument.
The Windows compatible software supplied provides access to all
configuration parameters and allows all setup files to be named and stored
for future use. Full context-sensitive help and an online User Guide are
available at all times when using the configuration software. The RS485
interface can also be used to access real time values, i.e. measurements,
values, alarm setpoints.
