Power supply activation, lead time
CAUTION!
Before activating the power supply check once again that the operating
voltage setting (see rating plate) matches the line voltage.
The sample gas flow should only be started after the lead time period.
Power supply
activation Activate the power supply using the externally installed breaker or the switched
outlet.
The diaphragm pumps and the dosing pump (and where applicable the hose
pumps in the sample gas cooler) start running.
Lead time The lead time for the sample gas feed unit is approx. 10 minutes. However, the lead
time of the connected sample gas cooler is of greater importance. In the case of the
SCC-C sample gas cooler the lead time is approx. 15 minutes.
Status signals The flow alarms are present during the lead time. The condensate alarms may also
be present.
Readiness At the end of the lead time period the sample gas feed unit is ready for operation.
Switch on sample gas The sample gas must not be switched on until the sample gas cooler’s lead time
has finished, i.e. until the sample gas outlet temperature lies within the limit values
set in the factory.
Set sample gas flow Set the sample gas flow using the appropriate needle valve.
CAUTION!
The needle valves must never be closed completely.
