Maintenance / service

When used properly, the control head IntelliTop 2.0 operates maintenance- and trouble-free.
For service work, we offer spare part sets for certain components or modules (see chapter entitled "21. Spare Parts"
on page 102). However, only the manufacturer may repair the control head for use in explosive atmosphere.
For active Service/maintenance notification function (see Chapter"6.8. Factory settings in the firmware" on page 26)
a maintenance prompt is issued - signaled by a "flashing pattern" in the fault color (1 s ON, 3 s OFF) - see Chapter
"17.2. Blinking pattern & fault signaling" on page 86.

Cleaning

NOTE!
Aggressive cleaning agents may damage the material!
• In the explosion-risk area, only wipe the control head with a damp or anti-static cloth to avoid electro-static
charges.
• The customary cleaning agents and foam cleaners can be used to clean the outside. We recommend
checking that the cleaning agents are compatible with the housing materials and seals before using the
cleaning agent.
→
Clean the control head and rinse it thoroughly with clean water to safeguard against the formation of deposits
in grooves and recesses.
If cleaning agent is not rinsed off properly, its concentration may considerably exceed the concentration
for use when the water has evaporated. The chemical effect will thus be several times stronger!
Observe the specifications of the manufacturer and the recommendations for use of the cleaning agent
manufacturer!
