Human Machine Interface - ABB RET670 Product Manual

Transformer protection RET670

Product version: 1.2
14. Metering
Pulse counter logic PCGGIO
Pulse counter (PCGGIO) function counts
externally generated binary pulses, for instance
pulses coming from an external energy meter, for
calculation of energy consumption values. The
pulses are captured by the binary input module
and then read by the function. A scaled service
value is available over the station bus. The special
Binary input module with enhanced pulse
counting capabilities must be ordered to achieve
this functionality.
Function for energy calculation and demand
handling ETPMMTR
Outputs from the Measurements (CVMMXN)
function can be used to calculate energy
consumption. Active as well as reactive values are
calculated in import and export direction. Values
can be read or generated as pulses. Maximum
demand power values are also calculated by the
function.
15. Basic IED functions
Time synchronization
The time synchronization source selector is used
to select a common source of absolute time for
the IED when it is a part of a protection system.
This makes it possible to compare event and
disturbance data between all IEDs in a station
automation system.

16. Human machine interface

Human machine interface
The local human machine interface is available in
a small and a medium sized model. The difference
between the two models is the size of the LCD.
The small size LCD can display seven lines of text
and the medium size LCD can display the single
line diagram with up to 15 objects on each page.
Up to 12 single line diagram pages can be
defined, depending on the product capability.
The local HMI is divided into zones with different
functionality.
• Status indication LEDs.
• Alarm indication LEDs, which consist of 15
LEDs (6 red and 9 yellow) with user printable
24
1MRK 504 117-BEN D
label. All LEDs are configurable from
PCM600.
• Liquid crystal display (LCD).
• Keypad with push buttons for control and
navigation purposes, switch for selection
between local and remote control and reset.
• Isolated RJ45 communication port.
