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 25
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", page 69
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.
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.
