VPSB-DC and VPSB-DC-E
174 / 234 H172203_1_001
15.4.3 Protection
All external interfaces are protected against short circuits (limiting the output current or with
current measurement and power switches).
The power stages are protected against over-heating.
15.4.4 Measurements Provided for Diagnostic
The on-board diagnostics supervise essential board functions like power supply and clock
synchronization. A two-stage watchdog mechanism checks for valid connection to the ELCB
and for valid power commands. In case of a failure the board will reset and switch off the
power stages.
The software running on the ELCB may notify the user about abnormal events.
Status / Errors
The VPSB-DC(-E) can perform the following checks:
• Power voltages OK.
• Short circuits / disconnected lines at heater or sensor interface connectors.
All connectors are equipped with current-shunt monitors. These measurements allow
detection of connected adapters and over-current conditions.
15.4.5 Calibration
There are no calibration settings to store on the VPSB-DC(-E).
