Industrial boiler control and monitoring:

This OEM design undertaken for a cutomer is an advanced boiler control unit for the control of large industrial boilers. The control taking the form of monitoring of exhaust gases from the boiler's burners to ensure safety of the burning process.

The unit also performs load sharing control between several boilers.

This design also incorporates a modem to enable remote monitoring and control to take place.

The design is based on the architecture of a FMT-200J utilising the standard CPU board utilises a Motorola 68000 family microprocessor but a specialy redesigned I/O board incorporating a modem and power supply and designed to fit into the enclosure of the customers choice. There is also an LCD display and four button keypad connected.

Special Features:

High safety integrity Different display options Special oxygen sensor signal conditioning module Flexible power supply options Modem interface 240V AC I/O Utilises standard FMT-200 microprocessor board

Remote Generator Control and Monitoring:

This OEM design is a device to monitor remotely situated backup generators (before this device was available an engineer would have to visit hundreds of sites every month to check on the generators condition).

The device comprises a FMT-100D without it’s case or terminals which was supplied to the customer who fitted it into a special ‘mother board’ of their own design.

This design also consisted of a specially written piece of OEM software which displayed the generator being remotely monitored as a mimic panel.

The FMT-100D was connected via the mother board to a modem which enabled it to be communicated with over the public telephone network, hence allowing very remote monitoring.

Special Features:

Modem interface Standard FMT-100D used (without casing and terminals) Special OEM software written - displaying the generator being monitored as a mimic panel

Engine / Gearbox monitor:

This OEM design for a large international car manufacturer consisted of a standard FMT-100C with specially written firmware.

It is used to monitor the engine / gearbox speed and data was logged at regular intervals in the battery backed RAM of the FMT-100C.

This data was downloaded after some time for analysis.

Irrigation control system for large manufacturer:

This design consists of a FMT-100 processor board mounted in a I/O board specially designed by Colter.

The unit controlls an irrigation system in the Middle East - because of this geographical location the design had to cope with extremes of temperature (up to 70 degrees C).

The unit controlles and monitored the irrigation sprinklers. Data for the weeks irrigation was downloaded to the unit once a week and the unit used it’s real time clock to 'know' when to perform irrigation.

Press batch counter / control:

This OEM design used by a large international car manufacturer is a controller which operates a press and also displays the current batch number.

The design utilised a FMT-100 CPU board mounted in a special I/O board designed by Colter. The board controls the press and also displays the batch number using a large seven segment LED display. The board was mounted inside a small enclosure with the display visible

Special Features:

Large character display Standard FMT-100 microprocessor board Special display / I/O board.

Control board for Industrial steam / vacuum cleaning machine:

This OEM design was for a control board for use inside a industrial steam cleaning / vacuum cleaner.

The board utilised a Microchip PIC microcontroller and controlled: boiler temperature, water level, vacuum on/off, steam on/off, chemical cleaner on/off.

The PIC was also utilised to monitor various parts of the machine alarm conditons for example: over temperature, low water level etc. If an alarm condition occured a bleeper was sounded and the event logged in the microcontroller's non-volatile flash memory.

Status and alarm conditions could be viewed / acknowledged via the LCD display and keypad (this was fitted to the front of the machine).

Operating parameters were also adjustable and were held in non-volatile memory.

Special Features:

PIC microcontroller based Data / Alarm Event logging LCD display Keypad Low cost solution

Electronic Humane Mouse Trap Board:

This OEM design was for small control board for use inside an electronic mouse trap.

The board utilised a Microchip PIC microcontroller and monitored a pressure pad within the trap, when a mouse walked over this pad then the trap could be set off.

The PIC was utilised to monitor the trap, the battery voltage.

An LED which was controlled by the PIC gave indication of low battery, whether the trap had been set-off and of normal operation.

The cost of this board was critical, and it was designed in such a way as to be very cost effective.

Special Features:

Low-cost PIC microcontroller based Economical use of components

Electronic Control Board used in a Home Flood Prevention Product:

This OEM design was for small control board for use inside an electronic home flood prevention product.

The board utilised a Microchip PIC microcontroller and monitored a flow sensor fixed in line with the main water inlet inside of the house just after the stopcock, it also monitored temperature.

Several LEDs on the board give status indication. If the water flow rate was suddenly extremly high (indicating a burst pipe) then the PIC would shut a solenoid valve in the water supply to the house, this could be overridden (for example if using a hose pipe).

If the water flow rate remained steady at a normal volume for a long period of time (thus indicating that a tap had been left turned on) then the PIC would close the solenoid valve and cut off the water supply.

If the ambient temperature dropped close to freezing point then the supply would be cut off by the PIC operating the solenoid valve - therfore avoiding a burst pipe.

The PCB was designed to fit inside a plastic moulding which was fitted around the solenoid valve and flow sensor.

Special Features:

• Low-cost
• PIC microcontroller based
• Small physical size
• Extensive use of surface mount componets to achieve small size

Operator Interface used with a large engine management system:

This OEM design was for an operator interface that was to be used with a large engine management system.

The customer dictated how the product should look, keypad layout etc. The customer also required a VFD Display (Vacuum Flourescent Display).

The unit was connected to the engine management system via a RS232 link. The menu layout was dictated to Colter by the customer.

Colter designed the electonics within the display, and wrote the software, Colter also procured the membrane keypad used on the operator interface and indeed all of the components.

Special Features:

PIC microcontroller based Designed to closely dictated requirements Interfaces to an existing piece of equipment Utilises a Vacuum Flourescent Display
