To set the lower and upper switching points for the alarm,
proceed as follows:
Changing alarm value 1
1. ALARM VALUE 1 > [OK].
The factory setting for the lower switching point is 0.15 mg/l.
(From start to end, the range is in the unit and resolution of the
measured value).
2. Factory setting > [Esc] or another value > [OK].
The factory setting is DOWNWARD VIOL.
An alarm is triggered in case
of a downward violation:
3. DOWNWARD VIOL. > [OK].
In case
the set value is not reached, an alarm is triggered, and
the following message appears in the 3rd and 4th lines: ClO
2
ALARM VALUE 1 DOWNWARD VIOL.
•
Remove the cause of the downward violation.
•
Confirm the alarm message.
An alarm is triggered in case
of an upward violation:
4. UPWARD VIOLATION > [OK].
In case
the set value is exceeded, an alarm is triggered, and the
following message appears in the 3rd and 4th lines: ClO
2
ALARM
VALUE 1 UPWARD VIOLATION.
•
Remove the cause of the upward violation.
•
Confirm the alarm message.
Changing alarm value 2
1. MAIN MENU > ALARM > [OK].
2. ClO
2
ALARM VALUES > [OK].
3. ALARM VALUE 2 > [OK].
The factory setting for the upper switching point is 0.70 mg/l.
(From start to end, the range is in the unit and resolution of the
measured value).
4. Factory setting > [Esc] or another value > [OK].
The factory setting is UPWARD VIOLATION.
An alarm is triggered in case
of an upward violation:
5. UPWARD VIOLATION > [OK].
In case
the set value is exceeded, an alarm is triggered, and the
following message appears in the 3rd and 4th lines: ClO
2
ALARM
VALUE 2 UPWARD VIOLATION.
•
Remove the cause of the upward violation.
•
Confirm the alarm message.
An alarm is to be triggered in case of a downward violation:
6. DOWNWARD VIOL. > [OK].
In case the set value is not reached, an alarm is triggered, and
the following message appears in the 3rd and 4th lines: ClO
2
ALARM VALUE 2 DOWNWARD VIOL.
•
Remove the cause of the downward violation.
•
Confirm the alarm message.
5.10.2 Setting the hysteresis
1. MAIN MENU > ALARM > [OK].
2. ClO
2
ALARM VALUES > [OK].
3. HYSTERESIS > [OK].
The factory setting is 0.01 mg/l.
(From 0 to halfway through the measuring range, the range is
in the unit and resolution of the measured value).
4. Factory setting > [Esc] or another value > [OK] > [Esc].
The HYSTERESIS function can be applied to both set alarm
values. The hysteresis
indicates the tolerance of the alarm value
(alarm value ± hysteresis/2).
5.10.3 Setting the alarm delay
1. MAIN MENU > ALARM > [OK].
2. ClO
2
ALARM VALUES > [OK].
3. ALARM DELAY > [OK].
Factory setting: 0 sec. (setting range from 0 to 999 seconds).
4. Factory setting > [Esc] or another value > [OK] > [Esc].
The alarm relay is switched on after the set time has elapsed.
5. Press [Esc] > [Esc].
5.10.4 Enabling dosing time monitoring
1. MAIN MENU > ALARM > [OK].
2. DOS. TIME MONIT. > [OK].
Disable dosing time monitoring:
3. OFF > [OK] > [Esc].
Enable dosing time monitoring:
4. ON > [OK].
The factory setting is 600 minutes (range 0 to 600 minutes).
5. Factory setting > [Esc] or another value > [OK] > [Esc].
An alarm is triggered when the controller specifies the set
maximum dosing flow for longer than the set time for the dosing
pump (Y OUT = X %).
