The Ampcontrol Pull Wire Supports are high quality E/Stop lanyard supports intended for use in overland bulk material conveyors and underground hard rock/coal mine conveyors. The Pull Wire supports are constructed from a flame retardant polymer compound, providing superior impact strength, rigidity and UV stability. The material is non-corrosive and low friction and complies with IECEx 60079.0:2012 anti-static requirements.
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.
iMAC Modules typically need to be programmed (configured) when connected to the iMAC L1 Fieldbus communication line. The iMAC Controller is used to program the modules. Each module (data register) must be programmed with an address and up to three other parameters. The parameters are used to control how a particular module behaves.
The SLE Signal Line Relay is designed to control conveyors in industrial and mining applications. The SLE Signal Line Relay is normally installed in the conveyor starter panel. The signal line is connected between the + and – Terminals of the Relay. The – Terminal is internally connected to the Earth Terminal. It is important that control switches are only connected to the + Signal Line.
Meet the challenges of maintaining safety while maximising productivity on underground and overland conveyors with Ampcontrol’s iMAC conveyor safety and remote isolation systems. With Ex ia certification for Group 1 explosive atmospheres and the ability to monitor distributed I/O over distances of up to 10km on a single cable run, the iMAC Conveyor safety and remote isolation systems are suitable for use on both underground and overland conveyors.
Ampcontrol’s Voicecom Tunnelling Amplifier (VAA) is a field communication module used either as a standalone system or as part of the Voicecom Communication System. It provides intercom capability with integrated microphone and speakers for use in mining and tunnelling applications.
The VCA Long Line Compensator as the name suggests compensates for the affects long communication lines impose on the system. The VCA Long Line Compensator is recommended for all Voicecom systems regardless of communication line length. It’s particularly required for communication lines exceeding 1.5km in length.
The Ampcontrol designed VoiceCom system is a multi-station audio communication system suitable for long wall and conveyor message applications. The system’s three principal functions include generating pre-start alarms, playing pre-recorded voice messages and one to many station communications.
The VIA Audio Isolation Barrier Module is an intrinsically safe voice communication audio isolation barrier, for use in Ampcontrol VoiceCom systems.
