After pressing the “F1” key on the keypad, the LCD display will tell you which transmitter
has developed the problem and then prompt you to press the “menu” key when done. A sample
message may be:

Tank #1 is the tank on the right when looking at the front of the control box.
This would imply that the pressure transmitter for Tank #1
4
is the source of the error. After
fixing the problem, pressing the “menu” key will return the system to normal operation. If the
problem is not fixed and the “menu” key is pressed, or if there is a second transmitter that needs
attention, it will display the original Sensor Connection Error message again. Pressing the “F1”
key will tell you which transmitter needs attention.
Sensor Error Solutions
The sensor error check function is designed to find problems such as a wire coming
disconnected, or a short in the transmitter. This feature will not determine if the transmitter
reading is off by any amount. If a Sensor Connection Error occurs, check the wire junctions at
the transmitter end and inside the control box. Confirm that all connections are made. If all
connections are made and the error condition does not go away, check the transmitter output as
shown in the Checking Transmitter Output section.
Check: Tank 1 Press.
