SB-7-RC-B Auto-Calibration Procedure
Model: PT-200RC
Software version: 9098-A, 9098-B, 9098-C, 9098-D, 9098-E, 9098-F, 9098-G,
9098-H, 9098-I, and 9098-J.
Tools Required: Needle Nose Pliers
Process:
1. Turn power switch on heater off and remove front cover
drawer.
Ensure that the software version on the microprocessor is one that is
listed above.
2. From the control circuit board, remove the 2-pin (rear) jumper from terminal
marked Acal using pliers or fingers (see figure 200-14). Be sure water in
recirculating system is cooler than set temperature on booster (under 140°F).
If unable to verify, keep booster heater power off and run the dishmachine
rinse.
3. Place magnet on modulating valve just to the right of the coil and move it
about 3/4” to the right.
4. Turn power switch on booster on. The burner will ignite in high burn.
5. Slowly remove magnet from modulating valve.
6. Over the next minute the gas flow will change slightly as the computer
determines the proper voltage for minimum flow. After the computer
completes auto-calibration the burner will automatically shut off.
7. Turn off power.
8. Wait at least 20 seconds, and replace jumper on the circuit board.
9. Turn power on and check the unit for normal operation.
