Controller
4.8.4 Control parameters
Setting range for all control variables:
Xp value Tn value pH value
1 - 500 % 1 - 00 min 1 - 100 s
The following parameters are set by the manufacturer before
shipment:
Controller Xp Tn Tv
Disinfection controller 35 % 15 min OFF
Automatic controller pH value 10 % 15 min OFF
Conductivity controller (option) 10 % OFF OFF
4.8.5 Controller direction
For the pH controller it is possible to select the control direction
raise pH value (dosing of alkalis)
lower pH value (dosing of acids)
The setting is made in the menu Main menu>Menu >Control-
ler.
NOTICE!
In the standard display an arrow (

or

) indicates
the control direction. The output terminal display also
shows the control direction.
4.8.6 Base load metering
A basic load dosage can be configured outside of the range of
control. This dosage takes place even if the PID automatic con-
troller output is 0 %. If a basic load is configured, this value is
represented in blue on the display screen in the y-display. The
y-display of the automatic regulation is represented in green. In
the status display, this condition is identified by a "+" after the
y-display. It should be noted that this basic load is always effec-
tive and independent of the regulation of a certain percentage of
the control elements, although the automatic controller does not
request any dosage. The basic load is separately adjustable for
each output to a maximum of 0 % of the control range.

4.8.7 Manual operation
Automatic controllers feature the possibility of a manual opera-
tion mode.
If an automatic controller is hand-operated, then a large "M"
behind the "Y" will appears in the status display and the y-dis-
play on screen will be "blue". In addition the hand-operated is
indicated in the lower line.
In the menu of the manual settings the controller output can be
adjusted to any value between 0 % and 100 % and saved di-
rectly.

NOTICE!
Manual operation is not reset automatically.

Adjustment of shock chlorination
For shock chlorination, the "free chlorine" controller is switched
to manual operation for an adjustable time and an adjustable
dosing rate. When the time has elapsed, the controller automati-
cally switches to automatic operation.
NOTICE!
The user must empirically define the time and the
dosing rate for shock chlorination before this func-
tion is performed.
The "shock chlorine" key is used at the same time for configuring
and starting shock chlorination. Set the time with the "Time" key.
Set the maximum output capacity with the "%" key.
Press the "OK" key to save the settings. The shock chlorina-
tion is indicated on the status display. The timer counts down
and indicates the remaining time in minutes. When the time has
elapsed, the controller automatically switches back to automatic
operation.
Main menu >> menu >> controller >> free chlorine >> manual operations
4.8.8 Timer dosing
The controller has a time control function for dosing active oxy-
gen (nitrogen peroxide). This function must be selected in the
configuration.
Two settings required:
Setting the dosing times for all week days in the service menu
Selecting the dosing rate in menu > controller
4.9 Alarms
4.9.1 Measured value alarm
For each measuring input a minimum and a maximum alarm can
be set. If a value is above or below this limit the alarm is shown
and an alarm relay changes to a common alarm. The alarm set-
tings of the relay and the automatic controller belonging to this
measuring input can be differently evaluated. The time delay of
the alarm is adjustable (delay)
4.9.2 Safety cutout (Y alarm)
The controller is equipped with a safety cutout. Should the output
power of the controller reach more than 95 % due to unexpected
events as for example a faulty sensor, a warning alarm is dis-
played for the controller to reset the controller power output to 0
%. This function is factory-activated. The time is adjustable.
Moreover adjusted basic loads are switched off in the event of
an emergency stop.
All alarms are displayed in text form on the screen. The alarm re-
lay is activated and the reading which caused the alarm is shown
in red.
NOTICE!
The alarms are represented in red on the display.
After clearing, reset the alarms by pressing twice the
OK key button.
