8.1. Commissioning of the chlorine
sensor with order codes 568524
and 568523
Before commissioning:
1. Open the measuring water outlet of the analytical measurement
chamber.
2. Slowly open the measuring water supply. A constant low flow
rate in a range of 15...30 l/h is recommended.
3. In the Operating Instructions of the remote controller type 8619:
- a) Menu "Parameters"
Mx: Inputs AI1 or AI2
Mode = Current
- b) Menu "Parameters"
Mx: Inputs AI1 or AI2
Range = 4...20 mA
- c) Enter for 4 mA: 0 and for 20 mA: 20.
