5.1.1.3. Outputs
The relay is provided with:
*
Three trip output contacts PO1, PO2 and PO3
*
Two non-trip output contacts SO1 and SO2
*
Three optional non-trip output contacts SO3, SO4 and SO5
Switchgroups SGR1...8 are used for routing internal signals from the
protection elements and the external trip signal to the wanted non-trip or trip
output contact. The minimum pulse length can be configured to be 40 or 80
ms and the trip output contacts can be configured to be latched.
5.1.1.4. Disturbance recorder
The relay includes an internal disturbance recorder which records the
instantaneous 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 elements. Any digital signal can be set to
trigger the recorder on either the falling or rising edge.
5.1.1.5. Front panel
The front panel of the relay contains:
*
Alphanumeric 2 × 16 characters
’
LCD with backlight and automatic
contrast control
*
Three target LEDs (green, yellow, red) with fixed functionality
*
Eight programmable target LEDs (red)
*
HMI push-button section with four arrow buttons and buttons for clear/
cancel and enter, used in navigating in the menu structure and in adjusting
setting values
*
Optically isolated serial communication port with a target LED.
An HMI password can be set to protect all user-changeable values from being
changed by an unauthorized person. The HMI password remains inactive and
is not required for altering parameter values until the default HMI password is
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.
