The ambient temperature of the current loop display can be altered by
■
additional components (e.g. through heat dissipation in the case, in
particular with a transmitter mounted within the case or by mounting it
in the connection head of a temperature probe with the radiated heat
EN
from the medium). The operator of the display must ensure that, even
in the event of a failure, the maximum permitted ambient temperature
of 60 °C is not exceeded.
The operation of this explosion-protected version is only permitted in
■
intrinsically safe circuits.
The programming set for the factory programming must only be used
■
by the manufacturer, as it does not have ATEX approval!
The programming of the display must only be made via the three
■
buttons at the rear of the display!
When cases are used, they must either have their own suitable
■
approval or comply with the minimum requirements.
IP protection of at least IP20 applies for all cases
However, light metal cases must be qualified in accordance with
■
IEC/EN 60079-0 section 8.1. In addition, non-metallic cases or
powder-coated cases must meet the electrostatic requirements of
IEC/EN 60079-0 or have a suitable warning note.
The current loop display can be built into either a model BSZ-H
■
connection head or BSS-H connection head (with or without
wall-mounting adapter). In this case, the case requirements referred
to are fulfilled. The cases are not constituent elements of the EC-type
examination certificate.
