25 / 31 page  25 ERROR MESSAGES ERROR POTENTIAL CAUSES SOLUTION Laser output disabled due to key switch Key switch not properly configured. Ensure the key switch is in the unlocked position for output current to flow. Laser output disabled due to BNC interlock No connection made at the rear panel ACTIVE LOCK. Either the provided BNC terminator, or a user interlock connection must be made to the ACTIVE LOCK at the rear panel for output current to flow. Laser output disabled due to D-SUB interlock Passive interlock pins not shorted at the LD D-SUB. Ensure the interlock pins (Pins 2 & 3) on the LD D-SUB are shorted together. TC output turned off due to sensor short Sensor connections are shorted. Ensure the chosen sensor is properly wired. TC output turned off due to sensor open Sensor is wired to the wrong pins. Ensure the chosen sensor is properly wired. TEC Load open No thermoelectric is present. Ensure the thermoelectric is properly wired. TEC Load short Thermoelectric connections are shorted together. Ensure the thermoelectric is properly wired. Internal overtemp condition The ambient air temperature is too high for the instrument. Reduce the ambient air temperature to 50°C or less. IntelliTune aborted User cancelled the IntelliTune scan. Change the desired settings and begin the IntelliTune scan again. Zero value TC current limit TC current limits are set to zero. Increase the TC current limits, and begin the IntelliTune scan again. Insufficient TC current limit TC current limits are too low. The instrument can't drive enough current to reach setpoint. Increase the TC current limits, and begin the IntelliTune scan again. Temperature going in the wrong direction. IntelliTune aborted. TEC polarity is reversed. Reverse the connection to TEC+ and TEC- and begin the IntelliTune scan again. Inadequate heat sinking. Load may be in thermal runaway. Increase heatsinking and/or airflow and begin the IntelliTune scan again. TC output Disabled. IntelliTune aborted. User turned TC output current off. With output current disabled, begin the IntelliTune scan again. Start IntelliTune with the TC output off. TC output current was enabled when the IntelliTune scan attempted to begin. Ensure the TC output current is disabled, and begin the IntelliTune scan again. Can't run IntelliTune in Manual Tuning mode. IntelliTune mode set to Manual Tuning. Ensure the IntelliTune mode is in either Disturbance Rejection or Setpoint Response, and begin the IntelliTune scan again. Starting actual temperature was too close to setpoint To start an IntelliTune scan, actual temperature cannot be too close to setpoint temperature. Change the setpoint at least 5°C away from ambient and begin the IntelliTune scan again. Recall OR Save Error Bad internal SD card Contact the factory Sensor change. Output current disabled. Output was enabled while changing the sensor. Disable the output current before configuring/changing the sensor. TC output disabled due to reaching upper or lower temperature limit. Temperature range limit is not large enough for system. If limits can be increased without damage to the load, increase the temperature limits. System in thermal runaway. If you see the temperature continually rising, consult Technical Note TN-TC01: Optimizing Thermoelectric Temperature Control Systems. |
