If the converter is controlled internally, the bridge between contacts 1 and 6 in
the D-sub plug is absolutely necessary!

External switching is carried out by the customer using potential-free contacts (see figure 6).
If the converter is controlled externally, the bridge between contacts 1 and 6
in the D-sub plug must be removed!

With external control, the switch on the front plate of the converter is out of function. The chosen gas

STARTING-UP
Before using the equipment for the first time, check that the safety measures specific to the installation
and process are observed!
The following steps are to be taken before the first starting-up:
• Connect converter to the mains; compare the mains voltage with the information on the identification
plate before starting up;
• If necessary, connect general alarm-contact to the measurement control station;
• Switch sample gas path to 'bypass' if possible;
• Insert catalyst cartridge into the mounting adapter (see 17.1);
• Introduce cartridge into the tube furnace until the limit stop and screw on the closing cap by hand;
inserting the cartridge is eased when the outside O-rings are humidified
• Set desired catalyst temperature (pre-adjusted at the works to 350 °C [662 °F] resp. 660 °C [1220°F])
using the temperature controller (see 18.3). The warm-up time is approximately 30 minutes;
The maximum working temperature of the converter is 680 °C [1256 °F], using
cartridge type C maximum 380 °C [716 °F].

• When the desired temperature is reached, switch sample gas path over to catalyst operation inter-
nally or externally.
When using a new catalyst cartridge for the first time or after longer periods
of storage at room temperature, the response time T
longer! A start-up period of approx. 2 hours has to be considered, until the
