5.2.6.2 Overview of function and leak test

1. Preparing the test

(see "Preparing the test", page 23).

2. Checking the exhalation valve

(see "Checking the exhalation valve", page 23).

3. Checking the inhalation valve

(see "Checking the inhalation valve", page 23).

4. Checking the drain valve

(see "Checking the drainage valve", page 23).

5. Leak-tightness test with positive pressure 

(see "Leak-tightness test with positive pressure", 

page 23).

6. Checking the relief valve

(see "Checking the relief valve", page 23).

7. Checking the response of the no-oxygen alarm

(see "Checking the response of the no-oxygen alarm", 

page 23).

8. Checking the pre-flush unit

(see "Checking the pre-flush unit", pag24).

9. Carrying out the high-pressure leak test

(see "Performing the high-pressure leak test (incl. 

constant dosage device)", page 24).

10. Checking the bypass

(see "Checking the bypass", page 24).

11. Checking the minimum valve

(see "Checking the minimum valve", page 24).

12. Checking low-pressure alarm 1 

(see "Checking low-pressure alarm 1", page 24).

13. Close the closed-circuit breathing apparatus.

5.2.6.3  Preparing the test

1. Switch on the test unit: Press the 

 button.

2. Set the selector switch on the test unit to 

.

3. Position the closed-circuit breathing apparatus and test 

unit next to each other so that both devices are easily 

accessible and the test unit can be operated easily.

4. Open the lid or remove it (see "Opening the closed-circuit 

breathing apparatus", page 16).

5. Remove the protective cap from the connecting piece and 

insert the connecting piece into the test unit.

6. Perform tests.

5.2.6.4 Checking the exhalation valve

1. Set the selector switch on the test unit to 

.

2. Tightly pinch the inhalation hose with your hand. Use the 

face spanner from the BG ProAir Test Set if necessary.

3. Pump once. The test unit must display at least -10 mbar or 

"Sensor out of range".

4. If -10 mbar is not reached, replace the exhalation valve or 

the exhalation valve disc.

5.2.6.5  Checking the inhalation valve

1. Set the selector switch on the test unit to 

.

2. Tightly pinch the exhalation hose with your hand. Use the 

face spanner from the BG ProAir Test Set if necessary.

3. Pump once. The test unit must display at least +10 mbar 

or "Sensor out of range”.

4. If +10 mbar is not reached, replace the inhalation valve or 

the inhalation valve disc.

5.2.6.6  Checking the drainage valve

1. Set the selector switch on the test unit to 

.

2. Flip the locking lever in the spring bridge and position it so 

that the pressure plate is blocked by the locking lever.

3. Pump until the pressure plate on the spring bridge pushes 

against the locking lever.

4. Continue to pump until flow noises can be heard at the 

drainage valve and read the value on the display. The 

drainage valve must open b10 mbar and 

+25 mbar.

5.2.6.7 Leak-tightness test with positive pressure

1. Set the selector switch on the test unit to 

.

2. Reduce the pressure on the test unit using the venting 

button to 7+0.5 mbar and wait until the pressure has 

stabilised.

3. Press 

 to start the timer. 

The test time must be 1 minute. When the test time has 

elapsed, the pressure difference is displayed. The 

pressure difference must not be greater than 1 mbar.

5.2.6.8 Checking the relief valve

1. Set the selector switch on the test unit to 

 until the 

locking lever can once again be moved. 

2. Latch the locking lever in the spring bridge once again.
3. Set the selector switch on the test unit to 

.

4. Pump until flow noises can be heard at the relief valve. 

Read-off the value on the display.

The relief valve must open b4 mbar and +8 mbar.

5.2.6.9  Checking the response of the no-oxygen alarm

1. Set the selector switch on the test unit to 

.

2. Pump on the test unit until the no-oxygen alarm sounds 

and the 

 symbol appears.

The warning stops after a few seconds, as the respiration 

is only simulated and no respiration occurs. The 

Connect ECU automatically switches back to Standby 

mode.

If the closed-circuit breathing apparatus has been laid 

out for too long, the Connect ECU will be in Eco mode and 

no alarm will be triggered. Place the apparatus in an 

upright position and then lay it down again. The 

Connect ECU is then in Standby mode and the test can be 

repeated.
