4.10.2Parallel Control Bus connection

In case of Parallel System, the communication between the units takes place through the

Control Bus Cables.

Each Parallel Unit contains the two boards “P13/P14

– IM0

2

22

– Bus Interface Board” (mounted on top of

the

board “P12

– IM0196

– RPA Board”) on which four connectors

J1A - J2A

and J1B - J2B are allocated.

All the parallel units are connected to the same control bus.

This connection allows:

·

The microprocessors of each unit to communicate with each other.

·

The oscillators of each unit to be locked together.

·

The regulation loops to compare the output current of each unit in order to equally share the Load current.

For increased reliability, this connection is made with redundant cables.
In this way, communication is maintained between units in case one of the control cables should fail or be
accidentally damaged or disconnected.

The standard length of the control bus cable between two parallel units is 40 ft / 12m.
The maximal overall length of bus connection, between the first and the last unit, should not exceed 295 ft / 90m.
Verify that control wiring run in an individual separate steel conduit.

Note!

Under no circumstance should the control bus cable connecting J1A - J2A (1/2/3/4/5) and J1B - J2B
(1/2/3/4/5) be connected or disconnected after the system has been powered ON.

Fig. 4.10.2-1 RPA System - Control bus connection

It is important to place the units in sequence of their assigned number.
A unit number from 1 to 6 is defined by the setting of parameters and displayed on the panel (1 to 6).
This number is also marked inside and outside the packaging.
