VEGA 33_Ex-33 - Manual (Page 2)

2 Module-33/Ex-33
Product description
Coding of the module
The multipoint connector can be provided with
coded pins to avoid interchanging of the differ-
ent instruments in the carrier. Coded pins are
attached to each module. Equip the multipoint
connector with these coded pins acc. to the
table and figure on this page. The multiple
plug of VEGA-instruments has appropriate
holes (mechanical coding).
Module for Ex-instruments:
The multipoint connector must be provided
with three coded pins. The coded pin for the
Ex coding (position c23) avoids that not-Ex-
instruments are plugged into an Ex-module.
