  • Page 13: Troubleshooting

    Trouble Shooting The Model 12V500 provides internal diagnostics that monitor proper simula- tor operation. If a monitored system detects a condition that is outside of the normal operation parameters, the simulator will deactivate the solution and head space heaters as well as the agitator motor. The simulator will emit an audible alarm and display the detected condition code number on the LCD followed by a message and icon detailing the condition.
  • Page 14 PROBLEM: The temperature sensor for the thermometer circuit is either open or shorted. REMEDY: Cannot be remedied in the field. Requires service.* PROBLEM: Temperature of solution is above 34.20°  C after initially reaching 34.00°  C . REMEDY: Turn off the simulator and allow the solution to cool. Turn the simulator on.
  • Page 15 PROBLEM: Temperature of solution has dropped below 33.80°  C after ini- tially reaching 34.00°  C . REMEDY: Turn off the simulator. Wait a few minutes then turn back on. If the condition continues to occur the simulator needs to be recalibrated or re- quires service.* PROBLEM: The temperature control circuit and the thermometer are reporting different temperatures.
  • Page 16 PROBLEM: Temperature of top housing has dropped below 34.5°  C after initially reaching set point. REMEDY: Turn off the simulator. Move simulator into a warmer environ- ment. Wait a few minutes then turn back on. If the condition continues to occur the simulator requires service.* PROBLEM: Temperature of top housing has risen above 36.0° ...
