14 Maintenance
Because the transmission of the devices remains reliable and stable over long periods of time,
regular adjustments are not required.
Keep the units clean so that the enclosure locks and screws remain accessible. Maintenance
may be required for the enclosure seal.
System maintenance should focus on the following:
a. Seal wear
b. Display damage
c. All screws are tightened fast
d. All cables and lines are properly connected and undamaged
If the device in its factory state is damaged or altered in any way,
decommission it immediately and contact the R. STAHL HMI
Systems GmbH !
If small glass beads (filling material) escape the device, immediately
decommission the device !
14.1 Damaged sealing
If the surrounding seal of the device is damaged, the R. STAHL HMI
Systems GmbH
will tick the “No hazloc approved panel mount“ option
on the device.
The device is only approved for installation inside an Ex e or Ex tb
enclosure if no "No hazloc approved panel mount" option is indicated
on the device !
15 Troubleshooting

may only be carried out by qualified, authorized staff specially trained
for this purpose.
Repairs may only be carried out by specially trained staff who are
familiar with all basic conditions of the applicable user regulations
