Starting up

Warning
Warning
Before connecting the device, make sure that the supply voltage matches the specified voltage on the
product label of the probe.
• Switch on mains power supply. The total heating-up time is approximately 2 hours. After about
1 hour the temperature of the probe is already higher than the temperature failure alarm value,
but it still takes about another hour until operation temperature has been reached.
After the minimum heating-up time of 2 hours, the gas sample dilution probe can start to extract
•
the sample gas.
Follow all relevant safety requirements and procedures regarding the sample gas type.
Warning
The following step-by-step procedure is recommended:
If using a manually operated ball valve, close it by turning the knob to the far right. If using a
•
pneumatic operated ball valve, close it with the pneumatic drive.
• Check the set temperature at the internal thermostate or at the external temperature controller.
Switch on the mains voltage.

Do not start-up the sample gas probe while potentially explosive
atmosphere is present.
The process and the environment of the probe needs to be
explosion-free (explosion-free zone) during start-up. A zone is
decleared as explosion-free zone, if it is free of explosive
atmosphere.
Connect the probe to earth (electrical bonding terminal).
The bleeder resistor needs to have an overall value of < 10
with protection cover: The protection cover does not need to be
connected to earth. Following the maintanance procedure, the
protection cover needs to be cleaned by damp cleaning wipes.
Only after the gas sample dilution probe has reached the operation
temperature stated in the technical data, gas can be released to enter
the injectors.
Prior to initial use, make sure that the mains voltage corresponds to the
voltage indicated on the type plate!
Do not touch the surface of the heated dilution probe during operation.
Due to its high surface temperatures, it may cause burns.
Wear protective gloves and protect the dilution unit against unauthorised
access!
