Thermostat Error Messages

Error messages are displayed in the user interface when an electronic failure

occurs with the autosampler thermostat module which requires attention. In

the event of such a failure, the red status indicator at the front of the

thermostatted autosampler is switched on, and an entry is written into the

instrument log book.

This section describes the meaning of autosampler thermostat module error

messages, and provides information on probable causes and suggested actions

how to recover from error conditions.

Each fan in the thermostat is equipped with a speed sensor, that allows

monitoring and control the speed of the fans. If the sensor shows no signal,

when the fan is activated, it is very likely that the fan is defective. The number

in brackets indicates the fan position. Position numbers of the fans are as

follows (seen from front of the thermostat)

• fan failed 1 - left side, fan in front position

• fan failed 2 - left side, fan in back position

• fan failed 3 - right side, fan in back position

• fan failed 4 - right side, fan in front position
