6 EFL Earth fault lockout and frozen contactor protection relay Ampcontrol s EFL is an earth fault lockout and frozen contactor protection relay compliant with sections 7 and 9 of AS/NZS2081:2011. While the outlet s main contactor is open, the EFL will continually monitor the resistance of the phase conductors to earth, on the load side of the contactor. If this resistance falls below an acceptable level, then the EFL will initiate an earth fault lockout trip, preventing the outlet from being started. The EFL will also monitor the state of the outlet s main contactor and compare it to the state of the auxiliary contactor. If a discrepancy occurs, the EFL will initiate a frozen contactor trip and open the upstream circuit breaker via the CBR contact. It also measures voltage on the load side of the contactor. If voltage is present after the back emf timer has expired, then the EFL will trip the CBR contact on an electrical frozen contactor trip. Features AS/NZS2081:2011 compliant Earth fault lockout protection Frozen contactor protection Compatible with a wide range of system voltages from 110V up to 1.1kV Selectable undervoltage protection function which, if activated, will open the main contactor if the voltage on the load side falls below 50% of the selected system voltage.

8 PF1 INTEGRATED PROTECTION relay Ampcontrol s PF1 Pump and Fan relay is an integrated protection relay which performs two standard protection functions and is compliant to AS/NZS2081:2011 earth leakage and earth continuity. The PF1 provides selectable control functionality for fan or pump motor installations. When applied correctly, these modes significantly reduce the risk of damage to equipment and also considerably reduce maintenance requirements. Pump protection mode manages the no-load/undercurrent condition of a pump by monitoring the load current. When the load on the pump motor decreases the speed of the pump motor will rise to its maximum, which can burn out the pump motor. Fan protection mode manages the gradual pre-inflation of flexible ventilation conduit, by applying a pulsed (burp) start-up sequence to the fan motor. Both functions can be deactivated. Features AS/NZS2081:2011 compliant 24VAC or 24VDC operation Selectable remote start/stop functionality LED status indication to aid in fault finding Event data logging Configurable parameters through USB connection to PC running Smart Tools Software Selectable pump protection mode (snore) can assist in maintaining optimum motor efficiency by detecting load decreases Selectable fan protection mode (burp) can prevent damage to the material of the ventilation tube during the initial stages of inflation 5 ampcontrolgroup.com June 2017

10 IPM V2 integrated protection RELAY Ampcontrol s IPM V2 is an intelligent microprocessor based protection relay. The IPM V2 relay provides all the functions required for protecting electrical outlets supplying underground mining machinery, powered by reeling or trailing cables. The relay can also be used to provide optimum overload protection of motors used on conveyors, pumps, fans and compressors. Additionally the IPM2 V2 provides pump (snore) and fan (burp) control to protect pump and fan motors. All of the protection functions are combined into a compact, plug-in unit, which can be easily changed to minimise downtime in the event of a problem with the relay. Machine data transfer is provided through the use of a Remote Termination Module (RTM) which allows the relay parameters to be automatically uploaded from the machine when a cable is inserted into a power outlet. The RTM also allows for remote start capability. An automatic insulation test ensures the resistance of the cable insulation to earth exceeds the selected value before allowing the main contactor to close. This is coupled with a manual insulation test to allow fault finding. Features Integrated protection functionality with pump and fan control Machine recognition using Remote Termination Module (RTM) RS485 communication port interfaces to SCADA system via Modbus protocol to provide continuous monitoring and fault finding 4-20mA analogue output allows continuous monitoring of the current, voltage, earth leakage and insulation levels Battery backed 50 event log with real time clock and 20 character backlit LCD display and keypad for ease of use Relay and digital input status to aid fault finding Local or remote operation including remote start capability Compact, plug-in unit which can be easily changed out to minimise downtime 7 ampcontrolgroup.com June 2017

12 MEC-1 earth continuity relay Ampcontrol s MEC-1 is a cost effective earth continuity relay compliant to AS/NZS2081:2011 which is typically installed in a substation or distribution box. The MEC-1 continually monitors the integrity of the earth connection in a mining trailing or reeling cable by connecting to the pilot conductor which is terminated to earth through a diode. The relay measures the resistance of the pilot-earth loop (series resistance) to ensure the integrity of the earth conductors and the pilot to earth resistance (shunt resistance) to ensure the integrity of the pilot to earth loop. If either the series resistance exceeds, or the shunt resistance falls below the configured settings, a trip will remove power. Features AS/NZS2081: 2011 compliant 24VAC/DC operation Diagnostic LEDs for fault finding Adjustable resistance and trip time settings Installed within a compact, DIN rail mounted unit with pluggable connectors for easy change out if required Selectable remote start and trip latching Diode termination 9 ampcontrolgroup.com June 2017

14 ECM3 EARTH continuity RELAY The ECM3 provides earth continuity protection for outlets with long runs of trailing or reeling cables. It has been designed with the safety requirements of AS/NZS2081 and AS/NZS4871 in mind. The ECM3 provides earth continuity protection using pilot earth loop or earth continuity monitoring. An additional core (the pilot core) is included with the power and earth cores in the trailing or reeling cables to the machine. The ECM3 relay monitors a low voltage DC signal applied between the pilot and earth of the cable and by measuring this signal determines the resistance of the earth pilot loop. Unlike its predecessor, the ECM2, the ECM3 s earth continuity trip threshold is able to be adjusted to just above the healthy resistance of the supply cable (adjustable in steps of 5Ω). Setting the trip threshold to within 10Ω of the cable s resistance ensures that the maximum touch voltage is kept within an acceptable range. The maximum loop resistance setting is 90Ω (excluding the 235Ω termination resistor). The ECM3 implements earth continuity protection using a unique Earth Continuity Trip Curve, whereby the magnitude of the fault is related to the speed of trip actuation. In this manner, a very high impedance fault in the earth return path (e.g. cable open circuit) will result in a very fast trip, and a fault where the earth return path gradually increases over the trip setting will result in a slower trip actuation. The substantial advantage of this method is that sources of pilot noise, such as cable slip rings and nonsymmetrical cables, have a significantly reduced impact on the ECM3 giving the ECM3 a far greater noise tolerance than other earth continuity relays on the market. Features Earth continuity protection Resistive termination unit for greater noise tolerance Unique earth continuity trip curve, providing resistance dependent trip speed and greatly increased noise immunity Selectable trip resistance from 15Ω to 90Ω in 5Ω steps Ability to determine the existing pilot-earth loop impedance DIN rail mounted External reset AC or DC supply operation LED indication to aid in fault finding 11 ampcontrolgroup.com June 2017
