ERROR MESSAGES

12.  ERROR MESSAGES

The pump controller shows error messages when erroneous conditions appear and when measured 
values are outside the expected range.
The information below provides an explanation of the errors, and recommended action to be taken.
Error messages are displayed with red LED backlight.

 

Probe is not connected.
Connect the probe.

 

Wrong probe is connected. 
Unplug the controller and connect the correct probe.

 

Broken temperature sensor.
Replace the probe.

Temperature is out of range.

Measured pH value is out of range.

Stepper motor error: over temperature or overcurrent 
is detected. 
When the error has ceased, the stepper motor 
resumes normal function
