8.1.5
Time Limit - Dosing time monitoring alarm
The controller is equipped with an intelligent, dynamic dosing time monitoring.
If the corresponding measuring value does not reach the control range within the
selected Time Limit time, e.g., due to a malfunction, the dosing stops with an
alarm.
A
is shown in the IN list, the alarm relay is activated and the dosing stops.
This alarm is automatically reset by reaching the control range, by a device restart
or a manual acknowledgement by pressing the MENU key.
The cause is usually a worn dosing head or a blocked dosing valve. The Set Output
dosing performance may be set too low.
8.1.6
General alarm
If a fault or an alarm occurs, this will be indicated by a
symbol in the OUT line.
The alarm relay is activated.
A differentiation is made between alarms (software alarms, e.g., alarm high, alarm
low) and faults (chemical container empty, measuring cell flow too low).
In the event of alarms, the respective measuring value is shown in red.
In the event of faults, the corresponding symbol appears in the In line.
Tip
An alarm is automatically cancelled when the cause has been eliminated, e.g., when an empty chemical container has
been replaced by a full container or when sufficient measuring water is flowing through the measuring cell again.
8.1.7
Temperature fault
If
- - - -
is displayed instead of a number for the temperature, there is a fault in
the temperature measurement.
This may be caused by the following:
1.
No temperature sensor connected (cable broken)
2.
Defective temperature sensor;
(resistance too high > 1.35 kΩ)
3.
Wrong sensor type (resistance too high
1.35 kΩ)
8.1.8
Measuring amplifier fault
If
- - - -
is displayed instead of the two measuring values pH and mV, there is a
fault at the measuring amplifier.
This may be caused by the following:
1.
No measuring amplifier plugged in
2.
Polarity of the measuring amplifier incorrect (22-pin header correct?)
3.
Measuring amplifier defective
