Defining The Polarity Of The External Shutdown Signal - Xantrex XTR 850 WATT SERIES Operating Manual

Defining the Polarity of the External Shutdown Signal

1. Turn the 9-position mode control to the PRT position or press the
2. Turn the rotary Adjust/Enter control until PrO SD is displayed.
3. Press the rotary Adjust/Enter control to display SD 0 (shutdown on
4. Press the rotary Adjust/Enter control to commit the desired polarity
Important:
the shutdown polarity should be set to 0 if it is not being used.
The SCPI command (s) for these instructions are:
[:]OUTPut[<channel>]:POLarity

setting.
For example: If you set the shutdown logic to 1 (SD1) and apply a
logic high (greater than 1.2 Vdc) to pin J3.12 relative to pin J3.6 on
the ISOL connector, the power supply will shut down. Conversely, if
you set the shutdown logic to 0 (SD0), the power supply will only
operate when you have a logic high (greater than 1.2 Vdc) to pin J3.2
relative to pin J3.6.
There is an internal pullup resistor inside the shutdown circuit so
