EMM - EPOCH MEMORY
EP011
Contains the database of protection function settings for all outlets and various loads. This information is transmitted to all outlets and connected to the EMM via a high speed group communication interface. Through this interface the run time data from each machine is available to the EMM in real time. The depth of memory available to the EMM gives it the advantage of being a gateway for external devices such as a PLC to access this data from each outlet and the configuration settings each outlet is adhering to. The memory interface takes on the important role of conducting synchronisation tasks between multiple outlets, for example, controlling outlets which are interlocked by a fan.

Motor Protection
Protection System
The Epoch Protection System is the new generation in protection devices, designed to provide complete protection to the AS/NZS 2081:2011 standard and is certified Intrinsically safe under IEC 60079.11 ‘Ex ia’ for electrical equipment in the mining and industrial environments. Using advanced microprocessor controlled technology and state of the art hardware design, the Epoch Protection System achieves high accuracy, long lasting reliability, and exceeds Australian standards requirements.
ECM - EPOCH CONTROL
EP012
The Control Interface unit of the Epoch Protection System and is the integral component that brings together the full protection functionality of each outlet. It performs the AS/NZS 2081:2011 Earth Continuity protection function on the outlet as well as receive and process signals from the Power Interface. The pilot conductor is connected through an EP041 barrier into the hazardous zone. It drives the HMI Display (EDM) and also controls the Main Circuit Breaker. External buttons for Start, Stop, and Reset are connected through the Control Interface.

EPIM - EPOCH INTERFACE
EP013 & EP014
The Power Interface is the heart of the Epoch Protection System and its purpose is to collect and process voltage and current signals in order to perform the protection functions for the system.
It controls the main-contactor for each outlet and the design makes it quick and easy to install.
The Power Interface enclosure has been designed to provide protection from electrical noise and as such ensures reliable operation in harsh target environments, such as high voltage switching cabinets. There are two intrinsically safe devices certified to ‘Ex ia’ installed in a Power Interface unit, the Real Time Clock (RTC) Flag Relay and the EFLO Barrier. When the EPIM unit is powered, the RTC Flag Relay and EFLO Barrier are not suitable for installation in a hazardous area and it is recommended that an ‘Ex d’ enclosure be used. When the EPIM is not powered, the RTC Flag Relay and EFLO Barrier are suitable to be installed or present in a
hazardous area.
