1.2 About the Processor
The Landmark Graphic AE Signal Processor is designed to be used in
conjunction with any LAND System 4 thermometer and ABT/S, AET and AQT
application dedicated thermometers.
The processor features include:
• Large, clear LCD panel.
• Easy to use conguration menu system, with security code, context
sensitive help display and ‘Quick Key’ selection of the most commonly
changed parameters.
• Multi-channel version for up to four thermometers.
• A choice of time function processing options for each thermometer input.
• Current and voltage retransmission outputs.
• Power supply for processor and thermometer(s).
The processor’s capabilities can be enhanced with several optional extras.
• Serial communications in either RS 232C or RS 485 format.
• Maths function option etc.
• A front panel cover which provides sealing up to IP65 standards.
NOTE
The LMG AE processor supercedes the LMG AS (‘Aluminium Snapshot’)
processor for ABT/S. All LMG AS functionality is available within LMG AE.
The AET input card is compatible with both AET and AETS thermometers.
The AQT input card is compatible with both AQT and AQTS thermometers.
ABT/S and ABTS/S thermometers are completely interchangeable in
all respects.

NOTE
The Landmark Graphic AE processor can be set up to display text in
either English, German, Italian, French, Spanish or Japanese. The
processor is supplied set up to display in English. Changing the language
setting involves removal of the back panel, therefore it is recommended
that the language is selected before installing the processor in a panel. If
you wish to change the language setting, refer to Section 5.0.
When the processor is used in conjunction with a System 4 Ratio
thermometer, the retransmission outputs of the processor can be
congured to indicate an abnormal condition (e.g. loss of target signal) by
either rising to the top of the signal range (i.e. ‘up scale’) or falling to the
bottom of the signal range (i.e. ‘down scale’). The processor is supplied
tted for ‘up scale’ operation. The mode of operation is set by means of a
link on each input board tted. To gain access to the link, the back panel
of the processor must be removed. Therefore, it is recommended that the
required mode of operation is selected before installing the processor in a
panel. Refer to Section 2.2.3.
Mounting the processor in a panel is best achieved by two people, one on
the viewing side and one at the rear of the mounting panel.
1) Refer to Fig. 2. Choose an area of your mounting panel of sufcient size
to contain the processor.
2) Carefully cut a rectangular area out of the panel 186mm/7.3in wide, by
138mm/5.4in high.
3) Refer to Fig. 3. Unscrew the four retaining screws on the rear of the
processor and slide out the two clamp bars.
4) From the viewing side, insert the processor in the mounting panel.

5) From the rear, re-insert the clamp bars into their channels and push
them up to touch the mounting panel.
6) Insert and tighten the retaining screws until the mounting panel is rmly
gripped between the processor front panel and the clamp bar.

WARNING
Risk of electric shock. Refer to the processor Service Manual
before removing the rear panel screws.
Ensure that the a.c. mains input is disconnected before
removing the rear panel of the processor.
2.2 Electrical Connections
The electrical connections to and from the processor are all made via
connectors on the rear panel of the processor. Fig. 4 shows the location of
the connectors.

2.2.1 Alarm output connection schedule
The alarm output connection schedule is given in Fig. 5. The alarm relay
contact rating is 50V a.c. or d.c. at 0.5A.
2.2.2 CMD (Command) input connection schedule
The CMD (Command) input connection schedule is given in Fig. 6.
The command signal is inactive when the voltage is >3.0V or open circuit
(i.e. track). The command signal is active when the voltage is <1.5V or short
circuit (i.e. hold).
The command input can be controlled via a remote switch, as shown in Fig.7,
or via potential-free contacts, as shown in Fig. 8.
NOTE
Each alarm is designed to be ‘fail-safe’. i.e. if there is a loss of power to
the processor, the alarms will remain in an activated state until the power
supply is restored.
