Connect the high-pressure hose. Tightening torque of the union nut: 30 Nm +/- 5 Nm
Connected high-pressure hose
The union nut must be firmly tightened, otherwise leakage of CO
2
is possible.
DANGER
Danger of suffocation and poisoning by leakage of CO
2
in high concentration
(> 4 Vol.-%).
Death due to suffocation.
Make sure that the union nut is firmly tightened. Observe the prescribed tightening
torque.
11.2 Commissioning an operator-provided inertization
If operator-provided inertization is used, ensure that it is correctly configured and functional.
The operator is responsible for the effectiveness of the customer-provided inertization measures.
Configuration
Setting O
2
sensor alarm threshold 1
To release the higher-level control system, alarm threshold 1 of the O
2
sensor can be set to the desired
value (e.g. 4 Vol.% O
2
). To do this, contact BINDER Service.
If desired: Set alarm threshold 2
To do this, contact BINDER Service.
Setting the inert gas flow rate
Set the flow rate for inert gas at the flow meter according to whether O
2
control or permanent inertization
with constant flow is to be used
To do this, the solenoid valve must be open. This should be done by means of an appropriate circuit.
