To change the digital output to type PULSE select Type with [Up]-
and [Down] buttons and by pressing [OK] button the type can be
changed with [Up]-, [Down] button to PULSE. Pressing [OK]
button will confirm the type of digital output.
After confirming three additional rows will be available.
To change the parameter value that will be mapped to 0 % select
[0 %] with [Up]- and [Down] buttons and by pressing [OK] button
the parameter value can be changed with [Up]-, [Down]-, [Left]-
and [Right] button. Pressing [OK] button will confirm the
parameter value.
To change the parameter value that will be mapped to 100 %
select [100 %] with [Up]- and [Down] buttons and by pressing
[OK] button the parameter value can be changed with [Up]-,
[Down]-, [Left]- and [Right] button. Pressing [OK] button will
confirm the parameter value.
To change the maximum of pulses/min (for 100 %-output) select
Pulses/min with [Up]- and [Down] buttons and by pressing [OK]
button the pulses/min can be changed with [Up]-, [Down]-, [Left]-
and [Right] button. Pressing [OK] button will confirm the
maximum of pulses/min.
To change the digital output to type PWM select Type with [Up]-
and [Down] buttons and by pressing [OK] button the type can be
changed with [Up]-, [Down] button to PWM. Pressing [OK] button
will confirm the type of digital output.
After confirming three additional rows will be available.
To change the parameter value that will be mapped to 0 % select
[0 %] with [Up]- and [Down] buttons and by pressing [OK] button
the parameter value can be changed with [Up]-, [Down]-, [Left]-
and [Right] button. Pressing [OK] button will confirm the
parameter value.
To change the parameter value that will be mapped to 100 %
select [100 %] with [Up]- and [Down] buttons and by pressing
[OK] button the parameter value can be changed with [Up]-,
[Down]-, [Left]- and [Right] button. Pressing [OK] button will
confirm the parameter value.
To change the maximum of pulses/min (for 100 %-output) select
Period [s] with [Up]- and [Down] buttons and by pressing [OK]
button the pulses/min can be changed with [Up]-, [Down]-, [Left]-
and [Right] button. Pressing [OK] button will confirm the
maximum of pulses/min.
9.3.7 Parameter info
The Parameter info screen shows a summary of all important
settings and information for one parameter.
9.3.8 pH Compensation
If the pH of the water is above 8.5 pH it is recommended to use
the automatic pH compensation for the chlorine sensor. The pH
compensation is only available for the chlorine sensor.
To enable the pH compensation select Type with [Up]- and
[Down] buttons and by pressing [OK] button the type can be
changed with [Up]-, [Down] button to Auto. Pressing [OK] button
will enable the pH compensation.
To define the source for the pH compensation (normally this will
be parameter pH) select Source with [Up]- and [Down] buttons
and by pressing [OK] button the source can be changed with
[Up]-, [Down] button to desired parameter (i.e. pH). Pressing [OK]
button will confirm the source parameter.
Remove parameter
To remove the selected parameter, select Remove with [Up]- and
[Down] buttons and confirm with [OK] button. This will remove the
parameter. If an input of a controller is linked to this parameter
the controller will be deactivated.
PULSE
[0 %] defines the parameter value for 0 %-output
(0 pulses/min);
[100 %] defines the parameter value for 100 %-
output (max. pulses/min).
Pulses/min defines the maximum number of pulses
per minutes for 100 % output. The highest number
is 180.

PWM
• [0 %] defines the parameter value for 0 %-output
(0 pulses/min);
• [100 %] defines the parameter value for 100 %-
output (max. pulses/min).
• Period [s] defines the duration of one pulse for
100 % output. The highest duration is 100 s.
