To open the event report:
1. Select > Info > Device information in measuring
mode.
2. Use ▲ or ▼ to scroll through the individual pages until the
event report.
The symbol indicates a failed sign-on only after 5
attempts.
4.7.1.3 Activating the pump
To activate the pump in (normal) measuring mode:
1. Check the sealing surfaces of the pump adapter to ensure
they are undamaged.
2. Place, align and tighten the pump adapter on the thread
port on the top cover. Check that the pump adapter is
mounted correctly. Avoid bending the pump adapter. The
gas detector automatically switches to pump mode as
soon as the pump adapter is mounted.
 The leak test starts automatically.
3. When the leak test is displayed, the suction inlet on the
probe or hose closes within 60 s and remains closed until
the leak test is complete.
4. Release the inlet opening.
● Leak test successful: Measurement starts.
● Leak test failed: Inspect the accessories and the pump
adapter and then repeat the leak test.
5. Observe the flushing times. For further information, see
the following chapter: "Special features when measuring
with the pump", page 34
6. Remove the pump adapter.
7. After completing the measurement, make sure that the
seal on the pump adapter is clean and that there are no
chips of metal on the seal.
Plug the protective cap onto the pump adapter to protect
the seal from damage and being deformed.
4.7.2 Alarms
In the event of an alarm, corresponding displays, the optical
alarm, vibration alarm as well as, if necessary, the acoustic
alarm are activated (configurable). For further information,
see the following chapter: "Alarm settings (factory
setting)", page 42
To acknowledge an alarm:
1. Select .
4.7.3 Special state
The operation signal is deactivated during a special state.
Special states are displayed by the following visual signals:
– Yellow LED flashing – 'warm-up 1' special state
– Yellow LED continuously illuminated – general special
state
No alarms are issued during a special state.
Exception: The calibration adapter is mounted in measuring
mode. In this case, alarms continued to be issued as long as
the measurement gas can reach the sensors.

3500
The special state is exited by resolving the potential error, in
the event of an intact gas detector, by switching to normal
measuring mode, or automatically after approx. 1 minute.
WARNING
Incorrect measurement!
A mounted calibration adapter blocks free gas diffusion to the
sensors. Correct measured values and alarms can no longer
be guaranteed.
► It is imperative to actively bump the sensors (e.g. test gas
cylinder with pressure reducer, flow 0.5 L/min).
4.7.4 Blocking alarm
The blocking alarm protects the CatEx sensor.
If the measuring range is exceeded significantly at the CatEx
channel (very high concentration of flammable substances), a
blocking alarm is triggered. This CatEx blocking alarm can be
acknowledged by switching the gas detector off and then on
again in fresh air.
If the gas detector cannot be switched off because the A2
alarm is active and the switch-off mode in the CC-Vision is set
to "Switching off not allowed during A2", remove the power
pack or place the gas detector in the charging cradle and
allow it to switch off automatically.
For more details, refer to the technical manual.
