Password protection
To protect against unauthorized or accidental incorrect
operation, the Blu-Sentinel SE electronics module works with
three password levels.
Depending on the user administration configuration (see Inst-
ruction Manual Chapter 6.3.8 “Menu “User administration””),
three user levels with different rights are available. You can en-
ter either a locking code or a password. The currently logged in
user is also displayed in this screen. If the locking code entry is
corrected, the pattern is displayed in green. If an incorrect lo-
cking code is entered, the pattern is displayed in red. If the user
data can no longer be found, please contact your service part-
ner.

Calibration
Free chlorine (Cl2) calibration
The free chlorine calibration is always a two-point calibration
process: zero point followed by DPD calibration.
During the calibration procedure, feeder output signals can be
maintained at constant output by enabling the "Hold function" first.
Zero-point calibration
1Press the symbol.
2Press the menu Calibration.
3Tap the measurement “Chlorine”.
4Press the parameter “Zero point”.
5Close the ball valve on the sample water inlet.
Make sure that the chlorine sensoris firmly screwed in.Otherwi-
se the measurement accuracy will be affected by inhomoge-
neous flow and inadequate sand cleaning. When the sample
water supply has been stopped, the display first drops rapidly,
and after approximately one minute slowly approaches zero.
During first commissioning, it is essential to wait for 5 minutes,
even if the display shows “0.00” or flashes after a few seconds.
6Wait until the displayed chlorine value no longer changes.
7Press the “Calibration” button.An input field opens.
8Press "Enter" to save the zero point.
9Open the ball valve on the sample water inlet.
Measuring value calibration (DPD)
10 After zero point calibration, wait at least 2 minutes.
11 Open the flow cell drain (drain) by approximately 1 turn and
extract a specimen of the sample water.
12 Determine the content of free chlorine in the sample using
a photometer.
13 Press the parameter “DPD”.
14 Press the “Calibration” button.An input field opens.
15 Use the input keys to enter the determined value.
16 Press "Enter" to save the entry.
pH calibration
During pH calibration, the buffer solution and the sample water
should have the same temperature. If there is a temperature dif-
ference of > 8 °C, first bring the buffer solution to the same tem-
perature as the pool water.
1Press the symbol.
2Press the menu Calibration.
3Tap the measurement “pH”.
pH 7 calibration
4Press the parameter “pH 7”.
5Close the sample water inlet and sample water outlet and
briefly open the flow cell drain (drain) to release the pres-
sure. Close the flow cell drain (drain) again.
6Place the beaker into thebottom clip and fill the beaker with
buffer solution "pH 7.00" or use the bag with buffer solution
"pH 7.00".
7Unscrew the pH sensor from the flow cell.
8Dip the pH sensor through the top clip at least 2 cm deep
into the buffer solution and move slightly until the indicated
pH value remains constant.
9Press the “Calibration” button. An input field opens.
10 Use the input field to enter the value to be calibrated for the
buffer solution.
11 Press "Enter" to save the entry.
pH X-span calibration
12 Remove the sensor from the buffer solution “pH 7.00”.
13 Wash the sensor in distilled water to prevent carryover of
buffer solution.
14 Press the parameter “pH X”.
15 Place the beaker into the bottom clip and fill the beaker with
buffer solution "pH 4.65" or use the bag with buffer solution
"pH 4.65".
If buffer solutions other than those stated are used, the pH value
of the buffer solution must be lower than pH 6 or higher than pH 8.
16 Dip the pH sensor at least 2 cm deep into the buffer solution
and move gently until the indicated pH value remains cons-
tant.
17 Press the “Calibration” button. An input field opens.
18 Use the keypad to enter the value to be calibrated.
19 Press "Enter" to save the entry.
20 Remove the pH sensor from the top clip.
21 Screw the pH sensor into the cover of the cell body of the
flow cell.
22 Open the sample water inlet and outlet again.
Offset compensation
If external influences result in a constant difference between
the displayed pH value and a pH value measured manually,
this difference can be compensated and the comparative value
entered in the Offset menu.
1Press the symbol.
2Press the menu Calibration.
3Tap the measurement “pH”.
4Press the parameter “Offset”.
5Use the keypad to enter the value from the comparative
measurement.
6Press "Enter" to save the entry.
The offset entry is deleted each time a new pH-7 calibration or
span calibration is performed.

4/4
ORP calibration (Redox)
ORP sensors have long running-in times. This means that after
calibration with calibration solution,it can take several hours for
the measured value to stabilize.
1Press the symbol.
2Press the menu Calibration.
3Select the “ORP” measurement menu.
4Press the parameter “Cal. value”.
5Place the beaker into the bottom clip and fill it with calibra-
tion solution "478 mV" or use the bag with calibration solu-
tion "478 mV" into the bottom clip.
6Close the sample water inlet and sample water outlet and
briefly open the flow cell drain (drain) to release the pres-
sure. Close the flow cell drain (drain) again.
7Screw the ORP sensor into the cover of the cell body of the
flow cell.
8Dip the ORP sensor through the top clip at least 2 cm deep
into the calibration solution and move it slightly until the indi-
cated pH value remains constant.
9Press the “Calibration” button. An input field opens.
10 Use the keypad to enter the value to be calibrated.
11 Press "Enter" to save the entry.
12 Remove the ORP sensor from the top clip.
13 Screw the ORP sensor into the cover of the cell body of the
flow cell.
14 Open the sample water inlet and outlet again.
