ERROR

POTENTIAL CAUSES

SOLUTION

The USB flash drive is missing or not

accessible. Please make sure that a USB

flash drive is inserted into the front panel.

To run a local TC scan, a USB flash drive

must be in place.

Insert a USB flash drive in the data port on

the front panel.

The USB flash drive was removed. The

scan has been aborted.

To run a local TC scan, a USB flash drive

must be in place.

Insert a USB flash drive in the data port on

the front panel

The internal temperature limit of the

instrument has been exceeded. Output

current has been disabled to protect the

laser.

The ambient air temperature is too high for

the instrument.

Reduce the ambient air temperature to

40ºC or less.

The TC scan was canceled by the user.

The Stop button was pressed during the

scan.

Scan was canceled because output

current is disabled.

The Enable button was pressed during a

scan, cutting current to the load.

An open circuit was detected at the

load. Please verify the load and load

connections.

The instrument cannot drive current

through the load.

Make sure the A1 and A2 pins on the

15 + 2 D-SUB are connected to the

thermoelectric or resistive heater.

A short circuit was detected at the load

terminals. Please verify the load and load

connections.

The instrument is detecting that there is no

resistance where the load should be.

Make sure the A1 and A2 pins on the

15 + 2 D-SUB are connected to the

thermoelectric or resistive heater.

An open circuit was detected at the sensor.

Sensor is wired to the wrong pins

Make sure the chosen sensor is properly

wired.

A short circuit was detected at the sensor.

Make sure the chosen sensor is properly

wired.

Shutdown at user limit

The actual temperature has exceeded

one of the temperature limits and an LD

Shutdown signal has been sent.

The temperature controller will continue

to operate, but the TE current will be

disabled. The active QCL or laser diode

was shut down, if the LAB instruments

were connected. The setpoint may be too

close to the temperature limit. Overshoot

is natural as the system is coming to

temperature.

IntelliTune aborted – Starting actual

temperature too close to setpoint.

To start IntelliTune, actual temperature

cannot be close to setpoint.

Disable current, allow actual temperature

to move away from setpoint, and restart

IntelliTune.

IF ANY OF THE ERRORS BELOW OCCUR,

PLEASE CONTACT WAVELENGTH TECHNICAL SUPPORT FOR FURTHER ASSISTANCE.

• An internal error occurred while reading data from hardware. Please contact the factory for further assistance.

• A timeout occurred waiting for output. Make sure the load is connected and interlocks are satisfied.

• An internal error was detected. Please contact the factory for further assistance.

• A fault in the internal +5V supply was detected. Please contact the factory.

• A fault in the internal +15V supply was detected. Please contact the factory.

• A fault in the internal -15V supply was detected. Please contact the factory.

• A timeout occurred waiting for the internal load power supply to stabilize. Please contact the factory.

• A problem has been detected in the instrument power supply. Please contact the factory for further assistance.

• A current surge has been detected in the instrument. Output has been disabled to protect the laser.
