Maintenance - Dräger VarioGard series Gebrauchsanweisung

Maintenance

Attach an address sticker to the slave registered.
– The first slave registered is assigned
Address 1, the second Address 2,
and so on.
– Once all the slaves have been
registered, the display reads e. g.:
Press the key to process the
registration data in the central unit.
During this time, display:
a symbol flashes in the bottom right
of the display to indicate system
activity.
– The function is quit and the measurement mode is active.
CAUTION
!
When the slave is registered, the system is (re)set to the factory
default settings. The only exceptions concern the preset alarms
(threshold, hysteresis, mean time) for the transmitters.
A customised configuration must therefore always be set or repeated
after registering the slaves.
An individual system configuration can be undertaken by Dräger Service.
