Disturbance recorder

REM 610 includes an internal disturbance recorder which records the momentary
measured values, or the RMS curves of the measured signals, and up to eight user-
selectable digital signals: the digital input signals and the internal signals from the
protection stages. Any digital signal can be set to trigger the recorder on either the
falling or rising edge.
HMI
The HMI of REM 610 is equipped with six push-buttons, an alphanumeric
2x16 characters' LCD, eight programmable indicator LEDs, three indicator LEDs
with fixed functionality, and an indicator LED for front communication. The
push-buttons are used for navigating in the menu structure and for adjusting setting
values.
An HMI password can be set to protect all user-changeable values from being
changed by an unauthorised person. The HMI password will remain inactive and
will thus not be required for altering parameter values until the default HMI
password has been replaced. Entering the HMI password successfully can be
selected to generate an event code. This feature can be used to indicate interaction
activities via the local HMI. For further information on the HMI, refer to the
Operator's Manual.
Non-volatile memory
REM 610 can be configured to store various data in a non-volatile memory, which
will retain its data also in case of loss of auxiliary voltage (provided that the battery
has been inserted and is charged). Operation indication messages and LEDs, the
number of motor start ups, disturbance recorder data, event codes and recorded data
can all be configured to be stored in the non-volatile memory whereas setting values
will always be stored in the EEPROM.
Self-supervision
The self-supervision system of REM 610 manages run-time fault situations and
informs the user about an existing fault.
When the self-supervision system detects a permanent internal relay fault (IRF),
which will prevent relay operation, the green indicator LED (ready) will start to
blink. At the same time the self-supervision alarm relay (also referred to as the IRF
relay), which is normally picked up, will drop off and a fault code will appear on the
LCD. The fault code is numerical and identifies the fault type.
