11.12.3 Exceeding limit values
If Limit value 1 is exceeded for a sensor:
• The LED of the relevant sensor flashes.
• ICON 1 is shown as "active" (inverted).
• The relay for limit value 1 is triggered.
• If the alarm relay is assigned to the exceeded
limit value, the alarm is triggered once any set
delay time has elapsed. See below.
If Limit value 2 is exceeded for a sensor:
• The LED for the relevant sensor lights up.
• ICON 2 is shown as "active" (inverted).
• The relay for limit value 2 is triggered (once any
set delay time has elapsed).
• If the alarm relay is assigned to the exceeded
limit value, the alarm is triggered once any set
delay time has elapsed. See below.
Display of the message for limit value exceeded:
To read the message:
• The message is displayed directly on the display.
• For example, if a limit value is exceeded, the
following message appears:
Cl
2
0.80
ppm
Limit value 1
1 2
exceeded
Resetting actions after a limit value is exceeded
When the measured value has dropped below the
limit value, all actions, which were triggered by the
limit value being exceeded are reset automatically.
Confirmation of limit value 2
The relay for limit value 2 usually remains activated
until the measured value has dropped below limit
value 2. "Confirmation" means that when the limit
value is exceeded, the relay for limit value 2 is
switched off again using [Esc] (and therefore also,
for example, the connected sprinkling installation),
even though the risk caused by the increased
chlorine concentration remains.
Indication of the exceeded limit value remains active
on the LED and display.
Warning
Only use this function if you are certain
there is no major chlorine leak!
Confirmation of limit value 2 must be set in
Note
the "Setup/Limit value relay/ Confirm. LV
2" menu.
1. In display mode, press the [Up] button to scroll up
until the message for the exceeded limit value 2
appears:
2. Press [Esc].
– The relay for limit value 2 (and therefore also
the connected sprinkling installation) is
switched off again.
3. Remove the cause of the exceeded limit value.
11.12.4 When an alarm is triggered
• If assigned in "Setup", the alarm relay is triggered
(once any set delay time has elapsed).
• The alarm message appears in the display when
the following occurs:
– an exceeded limit value, for example "Limit
value 1 exceeded"
– a sensor test fault, for example "Sensor 1, error
test"
– a fault in the plausibility check for calibration
data sensitivity: "Slope error"
– a current loop fault, for example open circuit
current output 1.
• The alarm LED flashes.
• ICON A is shown as "active" (inverted).
• The header flashes.
11.12.5 Confirming an alarm
Confirmation is not possible during an alarm if a limit
value is exceeded or in case of a fault in the
plausibility check for calibration data sensitivity, but
is possible in case of a sensor test fault or current
loop fault. Reset the alarm relay by pressing [Esc].
Indication of the alarm remains active on the LED
and display.
If the alarm condition is no longer met, all actions
which were triggered by the alarm are reset
automatically.
