Page 20: Information About The Device
The purpose of the battery is to buffer the real-time clock in case of an outage of the protective device's power supply. Since it is not used for normal operation of the EMR-3MP0, it is not expected under normal conditions that a replacement be necessary during the life-time of the EMR-3MP0. If, however, it happens that the battery needs to be replaced the EMR-3MP0 has to be sent to the manufacturer as a service request.

1.3 Modules, Settings, Signals and Values Modules, Settings, Signals and Values The EMR-3MP0 is a digital protection device that holds various data in its internal memory. Some data is meant to be changed by the user to adapt the functionality to the respective application, other data types are set by the device during run-time and are therefore read-only from the user's perspective.
Page 29 For example, every protection function features several blocking parameters. (See also ╚═▷ “Blockings”.) If a signal has been assigned to a blocking parameter then the respective protection function gets blocked as soon as the run-time state of the assigned signal becomes “True”.

Initially, the motor is stopped and the current is zero. As long as the EMR-3MP0 is not in a trip state, it permits contactor energization by closing its trip contact in series with the contactor. The contactor is energized by the operator or process control system through a normal two-wire or three-wire motor control scheme, external to the protective device.

4.2 Motor Starting and Control Module 4.2.5 Delayed Protection Enabling During Motor Starts When the EMR-3MP0 detects a motor start, various timers are started.
