Dräger RAB 7000 Instrucciones De Uso página 30

Status conditions of the gas transmitter that do not permit access
via the remote access box, are indicated via a flashing display of the
following contents:
"FLT" The gas transmitter is in a fault condition ("Fault").
(Details can be found in the manual for the Dräger
PIR 7000 / Dräger PIR 7200.)
"MNT" The gas transmitter is operated using a magnetic wand
("Maintenance").
"COM" The gas transmitter communicates via the serial
interface with another device or via the HART
("Communication").
"– – –" or The gas transmitter is temporarily unable to send data to
"NAN" the remote access box because of routines running
internally.
"SWU" The gas transmitter software version is not compatible
with the connected remote access box.
Remedy: Contact Dräger Service.
"CNP" Calibration not possible
Calibration not possible. Check sensor.
"zTO" Zero Time Out
Sensitivity calibration not possible because the last zero-
point calibration was made more than 24 hours ago.
Zero-point calibration necessary.
Behaviour after switch-on
All the LED segments are activated for 5 seconds directly after
switching power on to make sure that the display is functioning
correctly ("lamp test"). During this period, internal test routines are run
in the remote access box.
"RAB" will then flash on the display for a period of approx. 60 seconds.
During this time, it is not possible to access all menus.
The remote access box then changes to standby mode.
