Response Of The Output Contact Af For A Fault In The Measurement / Supply Circuit; Mounting - Camille Bauer SIRAX B 811-6 Betriebsanleitung

10.3 Response of the output signals A1 and A12 for a
fault in the measurement/supply circuit
The response of the output signals A1 and A12 can be
set with the aid of switches 1 and 2 on the DIP switch
S 201 (Fig. 13).

11. Mounting

The power pack SIRAX B 811 is plugged onto a backplane
BP 902.
When deciding where to install the power pack
(measuring location), take care that the limits of
the operating temperature are kept:
– 25 and + 55 °C for standard instruments
– 20 and + 55 °C for Ex version!
11.1 Plugging the module into the backplane
Before inserting the SIRAX B 811 into the
backplane, ensure that, ...
... the backplane wiring is in strict accord-
ance with the wiring diagram of the
module
... the backplane is coded correctly
according to the section entitled
"Mechanical coding of the backplane".
Read the instructions for the back-
plane.
... the red coding insert has been removed
from the backplane for SIRAX plug-in
modules with a power supply of
24...60 V DC/AC and that the power
supply is correct for the module.
1. Clip the module base onto the top-hat rail.
2. If the backplane is mounted vertically, turn the quick
release screws on the module to a vertical position,
respectively if it is mounted horizontally, turn the screws
to a horizontal position.
3. Press the quick release screws inwards with the screw-
driver until there is an audible click.
