5.9.3 Displaying the current input value for the water flow
meter
1. MAIN MENU > SERVICE > [OK].
2. WATER FLOW METER > [OK].
Displaying the current input value for the contact water
meter
• "Pulses per second", which correspond to the pulse rate
(xxx litres per pulse), and the flow.
• Disturbance variable in percent.
-------------------------------------------------------------------------------------
Calculation example with 5 l/pulse, Q
max.
= 2000 l/h:
2 m
3
= 2000 l;
2000/5 = 400 pulses/h = 0.11 pulses/sec.
This corresponds to a disturbance variable of 100 %.
-------------------------------------------------------------------------------------
In case the defined input values are exceeded or not reached, a
fault has occurred, for example at the water flow meter.
Displaying the current input value for the flow meter
• Corresponding current for the flow (in mA).
• Disturbance variable (in percent).
5.9.4 Displaying the process status
Examples:
1. MAIN MENU > SERVICE > [OK].
2. PROCESS > [OK].
3. STATUS > [OK].
5.9.5 Displaying the list of events

> [OK].
See the example for HCl.
8. Press [Esc].
Resetting the chemical consumption
1. ClO
