6.5.1 LED glow stick color signaling
The color of the LED glow stick switches bet-
ween white, yellow and red depending on the
operating state (chapterl 6.3.6).
LED white
•
All OK.
•
The device is working trouble-free.
•
No active errors or currently no message
in the message system.
LED yellow
•
Alarm that is configured as “unlatched”
has been activated. As soon as the cause
was rectified and the alarm is inactive, the
yellow color signal changes again.
•
Fault message became active (only with
enabled tank monitoring and if the Min
message from the Cl2 or pH tank is pre-
sent.)
LED red
•
Error message present.
•
Alarm that is configured with acknowled-
gment has been activated.

Calibration
When calibrating the measurements, variati-
ons in the calibration solutions, buffer soluti-
ons or comparative measurements are
adjusted. Calibration is performed for new
devices (first commissioning) and to recali-
brate existing measuring instruments in accor-
dance with maintenance regulations.
6.6.1 Calibration interval
The electronics module offers the option of
using automatic maintenance and calibration
intervals for disinfection, pH, ORP (Redox) and
fluoride measurement. In as-delivered status,
the maintenance and calibration intervals are
disabled. Activated calibration interval:
1 Call up the Home menu
2 Select the desired measurement (e.g.
Chlorine free). The “Measurement” menu
opens.
3 Tap the
Settings menu. The settings
menu for the selected measurement
opens.
4 The “Maintenance interval” menu opens.

ATTENTION
Damage to sensor!
Electrodes are highly sensitive! Do not soil
or damage! Comply with the safety data
sheets for the buffer solutions or calibration
solutions.
NOTICE
•
Calibration must be carried out on first
commissioning.
•
The calibration intervals are defined
depending on the area of application
and water quality.
•
Please observe the prescribed mainte-
nance intervals (chapter 7.1).
•
Always start with the pH 7 calibration!
•
Before calibration of the pH value with
calibration solution, the ball valves on
the sample water inlet and sample
water outlet must be closed and the
pressure released.
•
Open the ball valves again after calibrat-
ion.
