TS-15200 Error Detection

Overtemperature Errors

The TS-15200 features an onboard temperature sensor. You can read the onboard temperature through software and perform thermal validation.

The TS-15200 module automatically disables output when it enters an overtemperature condition. Overtemperature conditions occur if the module is sourcing high current and the cooling system cannot maintain an onboard temperature reading less than 100 °C. To recover from this error, first ensure the onboard temperature reading is less than 100 °C and that the cooling system is functioning normally and then enable the power output through software.

The module overtemperature error status can be read through software when module output is enabled or disabled.

Remote Sense Errors

If a remote sense error is detected, the TS-15200 automatically switches to local sensing mode. The following conditions will produce a remote sensing error:

  • Maximum total output lead drop (1 V) is exceeded
  • Either Remote+ or Remote- become disconnected from the DUT
  • An overvoltage state is detected on either Remote+ or Remote- pin

To re-enable remote sensing, first ensure that the wiring and DUT are free from all of the listed conditions. Next, disable power output to clear the internal errors. Finally, enable remote sensing and power output through software.

The module remote sense error status can be read through software when module output is enabled.

Auxiliary Power Errors

When using the TS-15200, the auxiliary power source jumper must be configured to select source power from either the front IO connector or backplane power connector. Additionally, the auxiliary power supply must meet the voltage input range requirements as defined in the TS-15200 Specifications.

If the power jumper is not configured correctly or the auxiliary power voltage input is out of range, the module returns an auxiliary power error and module output is automatically disabled. To recover from this error, first ensure that the jumper is configured correctly and the auxiliary power setting is correct and then enable power output through software.

The module auxiliary power error status can be read through software when module output is enabled or disabled.
