Maintenance work must be performed according to the inspection and mainte-

ues.
The following items must be ensured before carrying out maintenance work:
1. Make a note of the following values on the combustion calorimeter!
•
Wobbe i/s
•
Heating value/combustion value
•
Density
•
mV signals
•
mA signals
•
Internal pressure
•
Differential pressure, Wobbe
•
Differential pressure, air
•
Frequency of the fan control
2. Notify the control room
3. If no default values via PLC are possible, activate "Hold signal" on the combus-
tion calorimeter.
4. Close the shut-off valve on the combustion calorimeter after a leak test.
The nature and amount of wear depends greatly on the individual use and operat-
ing conditions. All specified intervals are therefore guide values.
To guarantee operational reliability, use only genuine spare parts of the manufac-
turer.
