10. Error advisory
Error advisory Cause Course of action
Slope rate error The slope rate determined in
the calibration is less than 3
mV/0.1mg/l. The calibration process may have lead to
errors.
Check
- the connections
- the pH value
- the flow
- the set temperature
and re-calibrate.
If a slope rate error is again displayed, the
electrode should be cleaned or replaced.
Error Input 1 Input 1 is not receiving a
proper signal. Check the terminal connections and, when
necessary, the electrode cable.
Error Input 2 Input 2 is not receiving a
proper signal. Automatic temperature compensation is
set but no compliant temperature sensor is
connected.
Water Deficiency The digital input has been
closed. Close the input when you wish to proceed
with control.
When a water deficiency sensor is con-
nected, this error advisory indicates that
the measurement water supply has been
interrupted.
