10.2 Inspection and maintenance
WARNING
Uncontrolled machine movements!
Risk of injury due to maintenance work at an activated machine.
▶
Unless expressly prescribed otherwise, deactivate the machine via the main
switch, lock it and remove the key before carrying out any work.
The following inspection, testing and maintenance work is to be carried out
regularly. The intervals for the same have to be selected in a way that - also
dependent on the operating conditions - expected deficiencies are identified in good
time. The check must, however, at least be carried out every
three years from the
date of manufacture of the valve.
The date of manufacture of the valve can be seen
on the name plate, see chapter 5.1.1 "Information on the name plate and the valve
solenoid housing".
Before the initial commissioning or re-commissioning of the valve in a system,
check whether the valve requires maintenance. If required, carry out
maintenance.
For order details for seal kits, please refer to chapter 10.6 "Spare parts".
In order to ensure a long life cycle and functionality, include the following activities
in your maintenance schedule for the overall system:
1.
De-energize and depressurize the connection line.
2.
Remove coarse dirt from the exterior.
CAUTION!
Damage to property and personal injury caused by electrostatic charging!
▶
In order to avoid electrostatic charging, clean the valve using a damp cloth only.
3.
Check all external fittings for completeness and tight seat.
4.
Check cable and line entry, plug screw, external grounding connection and
connection line for tight seat.
5.
Check valve for external leakage. Replace the seals, if required, see chapter 10.5
"Rectifying external leakage".
6.
Open the terminal box and replace any damaged seals, if required.
7.
Check the inside of the terminal box for corrosion. Corrosion is an indication of
leakage. In case of visible corrosion, remove the valve and have it repaired.
8.
Check the internal lines and braided wires of the valve solenoid for visible
damage. In case of visible damage, remove the valve and have it repaired.
9.
Check all screws and connections for tight seat.
