3.5 Evaluation unit

■

Evaluation unit with connection line (4 m)

The evaluation unit (EvU) serves in the measuring system as user interface and pre‐

pares and outputs the measured values and performs control and monitoring func‐

tions. The EvU can be located in the vicinity of the sender/receiver unit. It can also be

located up to about 1000 meters from the sampling point, e.g. installed in the switch

center or monitoring center, and performs the following functions:

•

Output of measured values, computed data and operating states

•

Communication with the peripheral equipment

•

Output of error messages and other status signals

•

Access during service (diagnosis)

3.6 Accessories

■

Connection unit

– For CAN bus with 24 V power supply

– To extend the distances 19 ... 1000 m between analyzer and evaluation unit

4 Important information on GPP measuring probes

CAUTION

Observe the following information during commissioning of the GPP measuring probe

to avoid damage to the measuring system and to achieve stable measurements.

•

Check the filter surface visually for damage.

•

Warm the probe up for about 30 minutes beforehand so that the temperature of

the window and triple reflector is sufficient to prevent condensation on the optical

surfaces.

•

Gas can escape at the measuring probe during overpressure processes when the

1/4" plug is open or loose. Air is suctioned into the measuring probe during low-

pressure processes. The measured value in the chamber then drops depending on

the low-pressure in the process, possibly down to zero.

•

Do not damage the filter when inserting the probe in the flange.
