Ampcontrol’s Gasguard Flammable Gas Sensor/Transmitter (ATEX) is supplied complete with an amplifier and a Liquid Crystal Display. The Gas sensor is housed in a cast stainless steel enclosure, has been approved to be intrinsically safe and is suitable for use in a Zone 0 hazardous area. A remote head version with up to ten metres of cable is also available for use on mobile machinery such as roof bolters and continuous miners.
This document is intended to provide a detailed explanation of the communications protocols supported by the iMAC2 Controller’s Ethernet port. The iMAC2 Controller uses industry standard Modbus TCP/IP protocol for exchanging data with compatible Ethernet devices. The iMAC2 Controller facilitates a Modbus Slave (server) device. This document is not intended to provide information on the operation of the overall iMAC System, individual modules or instruction on programming the iMAC2 Controller or modules. Please refer the relevant supplementary documents for this information.
In May 2018, the iMAC / iMAC2 Controller operating system firmware was modified to extend the iMAC Module Serial Number range. These changes occurred in iMAC Controller Operating System Firmware v4.0 (O.S. v4.0). Marcus Punch Pty Ltd was engaged to perform a safety integrity verification of these changes. iMAC2 report AMP-15-01-A1 Revision 3 (including Revisions 4 & 5) and iMAC report AMP-11-05-A2 Revision 2 (including Revisions 3 & 4) assessed these changes to be in compliance with the requirements pertaining to software modification and as a result the existing safety metrics (PFD and PFH) for the iMAC Controller, iMAC2 Controller, 2-wire and 3-wire iMAC systems remain unchanged.
The iMAC LIM is an Intrinsically Safe (Ex ia), highly configurable remote indication module, which interfaces directly to the iMAC Fieldbus.
The potential for arc faults to compromise the integrity of IP and flameproof enclosures was investigated in some depth in the 1990s. The outcomes of these studies allowed a determination of arc fault behaviour and identified some unacceptable risks. Since 1990 the design of enclosures has not changed significantly, however the energy levels have increased substantially. Hence it is prudent to revisit the hazards and assess any emerging risks.
For nearly 50 years Ampcontrol has designed, manufactured and delivered integrated electrical solutions that improve safety, maintain efficient coal mining operations and meet stringent regulatory requirements. From our humble beginnings to being recognised as an industry leader in electrical solutions, we have consistently ensured our products meet the expectations of our customers in terms of safety, performance, quality, technical excellence, reliability, efficiency and cost effectiveness.
Engaging Ampcontrol as your asset management partner means continuity of technical support from the OEM and a commitment to making sure the equipment runs as it is supposed to, doesn’t breakdown, and is statutory compliant. We know the operational value of what we design and manufacture which is why we are focused on optimising the equipment you have invested in and ensuring operational availability.
For Underground Mining & Hazardous Areas. Suitable for use on all diesel vehicles, electrically powered machinery and lighting in hazardous areas. Incorporating four high power LEDs and designed for maximum lamp life, the light provides a low power robust alternative.
The implementation of an effective electrical protection scheme is critical in ensuring the safety of personnel and equipment working with electrical systems. This paper outlines the types of electrical protection stipulated in AS/NZS2081 and explores the criteria for implementing each to ensure a safe and effective protection scheme.
This paper outlines the requirements of the new legislation including the key features and impact of the changes for applicable operations, with particular attention paid to electrical requirements.
