NOTICE!
Please observe the solenoid drive operating instructions (BTA).
6.0 Operation
DANGER!
Before commissioning a new installation or before starting up an installation again
after repairs or modifications, ensure:
The proper completion of all installation and assembly work!
Commissioning only by “qualified staff” (see point 2.3).
Installation or repair of existing guards and protection equipment.
6.1 Commissioning
Before commissioning, check the data on material, pressure, temperature and flow direction
with the layout plan of the pipework system.
Depending on the field of application, the local regulations have to be observed, e.g. the
operation safety order.
Residues in the pipework and the valve (dirt, weld beads, etc.) will inevitably result in leaks.
Leakage inspection of the installed valve.
6.2 Shutting
down
Depending on the field of application, the local regulations have to be observed, e.g. the
operation safety order.
6.3 Maintenance
Solenoid valves have to be checked at regular intervals for proper function and internal leak tightness.
The intervals for regular inspections have to be defined by the operator according to the operating
conditions. UNI-Geräte recommends an internal visual inspection once a year and an overhaul of the
valve after 2 years or after the following number of switching cycles at the latest:

Putting back into operation
When putting a valve back into operation, ensure that all the necessary steps described in section 5.2
(Installation) and section 6.1 (Commissioning) are repeated.
7.0 Troubleshooting
7.1 Detection
of
defects
DANGER!
Be sure to observe the safety instructions during troubleshooting.
If the malfunctions cannot be remedied using the following
“Troubleshooting plan (7.2)”
please
contact the manufacturer.
In the event of faults in the function or operating behaviour of the valve, check whether the installation
work was carried out and completed as described in this operating manual.
Depending on the field of application, the operation safety order must be observed.
