Troubleshooting

This section provides tips on resolving issues that may arise when using the LinkPad.

Control and connection Errors

This section describes the various error messages that LinkPad can generate when attempting to connect to or control a Linkam stage, and what
actions to take to resolve them. 

This error occurs when there is a connection broken on the stage temperature sensor. This error may be caused by a stage lead cable disconnected
from the stage or may indicate a broken wire on the stage temperature sensor. If the Stage lead is correctly connected, contact Linkam Scientific
technical support.

This error occurs when the stage type connected requires an additional cable connected to an expansion board in the T96, but it is disconnected.
Power the unit off and check that any additional cables (such as vacuum sensor or DSC sensor cable) are connected, and that you are using the
correct stage lead for your stage.

This error occurs when the connected stage calls for option boards to be fitted into the T96, but the system cannot detect those boards. Check that
you are using the correct stage lead and T96 control unit.

This error occurs when the T96 is powered on with no stage cable connected to it. Power the unit off and make sure your stage lead is connected to
the T96 controller.

This error occurs when the water temperature sensor in your stage reaches too high a temperature. Check that the water pump is actively pumping
and that the water has not become too warm. This error can only occur with peltier stages.
