This must be noted in the event of any contamination.
► Clean contaminated pressure vessels and purge the
PID 5000 as required (see chapter 6.2.1).
► Replace the Dräger-Tubes (5) for the gas treatment as
soon as contamination above the main alarm exists.
The PID 5000 is pre-assigned with the alarm threshold in
accordance with DIN EN 12021. The pre-alarm is triggered at
0.1 mg/m³ and the main alarm at the limit value in accordance
with DIN EN 12021. The same values are also stored in the
Air Guard.
WARNING
Danger due to failure of an alarm
A change in the alarm settings may mean that the alarm does
not trigger when the limit value in accordance with
DIN EN 12021 is exceeded.
► Only adjust the alarm after consulting with Dräger Service.
The PID 5000 has two adjustable alarm levels:
"Alarm LO" (pre-alarm): 0.1 to 10 mg/m³
"Alarm HI" (main alarm): 0.2 to 10 mg/m³
NOTICE
"Alarm HI" (main alarm) must always be set higher than
"Alarm LO" (pre-alarm).
The set alarm levels only control the PID 5000’s LEDs. The
Air Guard, to which the PID 5000 is connected, evaluates and
responds to the alarms.

CAUTION
When changing the alarm values on the PID 5000, also
change the alarm values in the Air Guard accordingly.
