6 Commissioning
6.1 Preparations for commissioning
The commissioning of the pressure control panel may only be carried out after the integration
into the inventory has been completed. Commissioning is not permitted until the incomplete ma-
chine has been installed into a complete machine and this corresponds to the provisions of the
EU Machinery Directive and the EC Declaration of Conformity according to appendix II A.
Before putting the equipment into operation for the first time, the entire pressure control panel
must be purged via the PLI valve right up to the process. It is imperative to adhere to the direc-
tion of the gas flow when doing this. You must not purge counter to the usual direction of flow
(from the tapping point to the pressure control panel), since this can flush debris resulting from
the installation work, for example, back into the pressure regulator (PR).
The connecting threads and connecting surfaces of the gas source valves as well as the sealing
rings must be checked to ensure that they are in perfect condition.
Always turn shut-off valves as far as the stop when opening or closing them.
Make sure that:
– the fittings are marked for the corresponding gas type,
– all protective caps have been removed,
– the assembly has been correctly carried out and a leak test has been performed,
– all valves are closed (the red marking is visible in the handwheel window)
– the pressure regulator has been depressurised (if possible),
– the purge gas supply (only standard for SP4 and SP6) is in operation,
– the on-site exhaust gas system is functional at all times and is in operation,
– all shut-off armatures are checked for loose connections and
– the controller is in operation.
NOTICE
For the actions described in the following chapters, the controller must be connected and ready
for operation and in a manual mode.
6.2 Procedure for commissioning
6.2.1 Connecting the process gas source
1. Place the process gas source in front of the bracket and secure with the safety chain.
2. Remove and retain the protective cap and sealing nut on the process gas source.
3. Remove the plug from the gas connection.
4. Check connection thread and sealing. A new sealing must be used for each gas source ex-
change.
5. Screw the gas connection onto the gas source valve by hand and tighten it gas-tight with a
spanner.
6. Perform a leak test as pressure or leak test. The HPI remains closed in this process (see
