If the faults occurred cannot be resolved using the remedy measures
described or if other not described faults occur, the remote access box
must be checked by the Dräger service department and where
applicable repaired.
Remedy

Description of design

The remote access box consists of a housing, a flameproof converter
module (with integrated electronics and software), a cable gland and
a blind plug.
The housing made of conductive plastic prevents electrostatic charge-
up and is resistant to solvents.
The connection of the remote access box to the gas transmitter is
carried out via a three-wire line, with communication between the
remote access box and the gas transmitter is carried out via the serial
interface (ICOM, white connection lead).
