The Manual menu contains these selections:
1. Software Date Code—a display of the software type and date code, both of which are fixed
in the software; and the industry type, which is determined by setting the DIP switches on the
processor board.
2. Test Inputs—allows viewing of microprocessor inputs for testing when a formula is not run-
ning. Devices, including the door latch and the level transducer, provide signals to the micro-
processor by grounding certain inputs. The status of these inputs can be monitored in this
mode, and changes to the input status will appear instantaneously. Refer to 4.1.7: Viewing In-
puts and Outputs During Operation, page 71 to view the status of inputs while the machine is
operating.
3. Test Outputs—allows the actuation of outputs for testing when a formula is not running. Out-
puts are signals from the microprocessor to other devices, such as chemical pumps and motor
contactors. Refer to 4.1.7: Viewing Inputs and Outputs During Operation, page 71 to view the
status of outputs while the machine is operating.
4. Test DIP Switch—displays a hexadecimal number which is unique for each possible setting
of the DIP switch. This number can be used with the appropriate tables to determine the in-
dustry configuration of the machine, as well as whether the machine is configured to allow
the operator to skip certain steps during automatic operation.
5. Test Temp and Level—displays the pressure transducer voltage, actual level and calculated
level on the top line; and the temperature sensor signal and actual temperature on the lower
line. This menu selection is used with special testing equipment to calibrate the machine at
the factory.

The machine must be idle (power on, but not running a formula)
before the Manual menu can be accessed. Also, the Run/Pro-
gram keyswitch must be at the Run position (
).
