Woodward LS-5 v2 Series - General Functions; General Preparation

Priority during breaker closure
In an emergency application the simultaneous closing of two circuit breakers is blocked
via communications between the LS-5 and the easYgen. Once an easYgen is enabled for a
dead bus connection, it has priority over all LS-5s (any CB controlled by an LS-5 cannot be
closed).
If multiple LS-5s are enabled to close a circuit breaker at the same time the LS-5 with the
lowest CAN identi󰈡cation number receives the master status (all other LS-5s are inactive).
When a closure failure occurs (╚═▷ “4.4.2 Breakers”), this LS-5 is no longer considered for
dead bus closure. The next prioritized LS-5 takes over.
If the LS-5x2 gets simultaneously instructions to close breaker A and B, the CBA closure is
executed 󰈡rst.

General Functions
6.4.2.1 General Preparation
⚙
Prepare the easYgen – LS-5 system for con󰆟guration as follows:
1. ▷
Draw a single line diagram that only contains essential equipment.
The schematic should contain all used easYgens, all transformers, all breaker elements
(such as circuit breakers and isolation switches), all elements to be controlled, and all
LS-5s.
2. ▷
Assign numbered addresses for each component of the system in accordance with the
methods described in ╚═▷ “6.3.1 Introduction”.
3. ▷
Number all easYgen control units from 1 to 32 (order is user-de󰈡ned and depends on
your application).
4. ▷
Number all system LS-5s from 33 to 48 (order is user-de󰈡ned and depends on your
application).
5. ▷
Number all CAN Node-IDs (usually the same as the device number).
6. ▷
Number all segments according to the de󰈡nitions in ╚═▷ “Segment number”.
Unless special numbering conventions are required, count up continuously
from left to right or right to left.
7. ▷
Draw the measurement system A and B of the single LS-5 into the single line diagram
according to the de󰈡nitions in ╚═▷ “6.3.1 Introduction”.
