SB-7-FT Automatic Calibration (AutoCal) Procedure
Model: PT- 200FT
Software version: 9097-I,J & T and 9099-C, D & T
Tools Required: Needle-nose pliers
CAUTION: During this test the unit will be performing several self tests. Do not
attempt to use dish machine. The booster heater will increase the gas flow from
minimum to maximum over 8 minutes. Be sure to monitor the unit for safe
operation.
Process:
1. Turn power off and remove front cover. Open electronic drawer. Ensure that
the software version on the microprocessor is one that is listed above. From
the front circuit board, remove the 2-pin jumper cap from ACAL (back jumper)
using pliers or fingers (see figure 200-14).
2. Lock the dish machine in rinse mode. (Rinse MUST stay on for the entire
procedure).
3. Turn heater power on. Green LED should flash and burner comes on to high
burn and immediately drops back to low burn. If red light flashes there is a
problem that must be corrected first, and then restart this entire procedure.
See PT-200FT service codes for what each code means.
4. Over the next 8 minutes the unit will increase the gas flow to calibrate the
valve. The unit will run the test by itself and only requires monitoring for
safety. When the test is ended the red LED will flash rapidly and the burner
will shut off.
5. Replace the 2-pin jumper cap on the board.
6. Turn power OFF, wait 20 seconds and turn power back on.
7. Check the unit for normal operation. If operation appears normal the
procedure is complete. If the unit does not operate correctly or gas flow
varies excessively repeat the procedure.
