en Operation
4.7.1.3 Activating the pump
To activate the pump in (normal) measuring mode:
1. 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.
2. 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.
3. 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.
4. Observe the flushing times. For further information, see
the following chapter: "Special features when measuring
with the pump", page 33

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 41
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.
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.
32
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
acknowledge by switching the gas detector off and then on
again in fresh air.
For more details, refer to the technical manual.
