ABB G3HF HENF331051R0009 Trip Counter Module

G3HF HENF331051R0009 Trip Counter Module

The G3HF HENF331051R0009 is a trip counter module, it contains two two-digit counters for recording the numbers of transmitted and received commands. The display can be switched between the two combinations of NSD 70D commands A/B or D/E. The counts remain intact in the event of an power supply failure.

This is an optional unit, which enables the number of commands transmitted and received (signal A/B signal D/E) to be counted. The respective counts can be read from the 7 segment LED display on the front-plate. In the event of a failure of the power supply, the counters are buffered by a capacitor and a lithium battery, so that the counts remain intact, but are not displayed. The lithium battery has sufficient capacity for at least 500 hours. The capacitor can maintain the counts for about 10 minutes to cover short periods when the battery is removed or switched off.

Block Diagram

TX TRIP COUNTER, RX TRIP COUNTER:

Internal trip counters are available from firmware release 1.1.00. No buffer battery is provided, so that the counter information is lost following an interruption of the power supply or a reset. Where all 6 commands are being used with internal counters, a second redundant power supply unit is recommended.

The capacity of the counters is 65535. Their actual level can be obtained using the pocket terminal or a standard XT/AT PC.

The trip counters monitor the digital signals (PTXA ... F and PRXA ... F) between the DSP module and the relay interfaces. The internal trip counters (firmware) have fixed delay and latching time settings and differ in this respect to the external trip counters (G3HF). The latter are controlled by the relay interfaces which prolong the digital signals (PRXA ... F) by a pre-set command latching time.
