COMMISSIONING
8.4
Recognizing the safe operating state
The system is in proper operation when:
●
A system check has been carried out according to the Maintenance plan before
commissioning and in running operation.
●
Only the green status indicator on the control unit lights up and the operating status
“Measuring operation” is shown on the display.
Recognizing malfunctions
Any deviation from normal operation must be regarded as a serious indication of a
functional impairment or unsafe operating state. These are, amongst others:
●
Warnings displayed (e.g., high contamination)
●
Significant drifts in measured results
●
Increased power consumption
●
Higher temperatures of system components
●
Monitoring devices triggering
●
Smells or smoke emission
Necessary insulation
The thermal insulation is an explosion protection measure to be subjected to special
examination when gas temperatures in the duct are higher than the surface temperature
allowed by the selected temperature class. Observe the following during this examination:
– Apart from the duct surface, other parts (e.g. flange tube and flange) that can be
subjected to prohibited high temperatures through thermal conduction are to be
included in the insulation or the thermal conduction prevented
– The operator must ensure that suitable insulation reduces the heat radiation so that the
pressure-resistant enclosure temperature is below 85 °C and therefore remains below
the temperature for the temperature protection class. The operator must take into
consideration that the device-internal warming can be up to 2K
– The maximum ambient temperature of 60 °C must be observed during operation (
Electrical connection
Ensure the device can be switched off with a power isolating switch or circuit breaker in
accordance with EN 61010-1.
