Mounting
2.3 Selection of the plug position
The plug position for the individual cards is
initially individually selectable, the system
saves the cards’ positions when switched on.
Note:
The plug positions should not be modified
later on, as, otherwise, a new configuration
would be necessary for the measurement
loops already created.
Due to the bus board with the bus plugs,
there is a fixed pattern for the use of the
modules. It is, therefore, ensured that each
module card is inserted into the appropriate
multipoint connector, as well as into the LOG-
BUS-socket.
Number of TE:
- 84 TE, one thereof 4 TE-blind cover on
module 1
Width of the module cards:
- 5 TE for CPU and periphery
- 10 TE for VEGASTAB 593
Number of module cards in BGT LOG 571:
- 16 pieces (e.g. 1 x power supply unit, 1 x
CPU and 13!x peripheral cards)
2.4 Coding
A mechanical coding system avoids inter-
changing among the different module cards
in the carrier. It consists of:
- two coded pins in the multipoint connector
in the carrier
- two holes in the multiple plug of the appro-
priate component.
The coded pins are attached to the module.
Equip the multipoint connector with the two
coded pins acc. to the “Coding table“ and
“Position of the coded pins“. The function
coding characterises the module cards of
VEGALOG. The instrument coding differenti-
ates the individual module cards.
The multiple plugs of the individual module
cards are supplied with the appropriate
holes for the pin positions.
