Instrument Setup
4.1. Establish Sample Flow
The pressure regulator valve only works if the inlet pressure at the
main flow control valve is 0.5 bar higher than the outlet pressure.
The 500 mm capillary tube reduces the pressure by a further 0.5 bar.
Therefore, the pressure within the sample tube must be at least 1
bar, or better 1.5 bar.
Periodic pressure variations in the sample tube can cause pulsations
of the pressure regulator valve. This can be eliminated by using a
pulsation attenuator in the inlet tube.
1
Open the sample inlet valve at the inlet of the measuring cham
-
ber.
Note:
This valve is not intended to regulate the flow rate.
2
Pull out the adjusting knob of the pressure regulator valve and
open the valve.
3
Wait until the measuring chamber is full and the sample flows via
overflow into the waste.
4
Switch on power.
First, the analyzer performs a self test, displays the firmware
version and then starts normal operation.
5
Regulate the sample flow with the pressure regulator valve to 6–
18 l/h.
The sample flow (in l/h) is shown on the transmitter display.
6
Push in the adjusting knob to lock the valve.
4.2. Programming
Program all parameters for external devices (interface, etc.). Set all
parameters for instrument operation (limits, alarms).
Program the automatic cleaning intervals.
