Using The Shutdown Function (Output On/Off); Controlling Output On/Off Via Front Panel; Controlling The Interlock Function Via The J1 Connector - Xantrex XPR 10-600 Operating Manual

Using the Shutdown Function (Output ON/OFF)

Use the shutdown function to disable or enable the supply's output so that you can
make adjustments to either the load or the power supply without shutting off the
power supply. Activate this function from the front panel at any time by using the
OUT ON/OFF switch. You can also activate it via remote control through the rear
panel J1 Programming and Monitoring connector, using a 4 V to 15 V signal or a
transistor-transistor logic (TTL) compatible signal. The input lines for the Interlock
circuit are optically isolated.
Controlling The OUT ON/OFF switch is a press ON/press OFF switch located on the power
supply's front panel. Push the switch to its IN position to disable the output. The
Output
output voltage and current fall to zero and the OFF LED turns on. Push the switch
ON/OFF via
once more to reset it to its OUT position and resume normal power supply operation.

Controlling The Interlock (TTL Shutdown) circuit accepts a 4 V to 15 V signal to disable or
the Interlock enable the power supply output. Make connections for signals at connector J1,
located on the unit's rear panel. Set rear panel switch S1-7 to select signal logic. (See

To activate the Interlock (TTL Shutdown) function:
1. Turn OFF the power supply.
2. Connect the signal source to J1 connector terminal 12 (Interlock Input/positive)
3. Set switch S1-7 to select the desired circuit logic as set out in
4. Turn on the power supply. The power supply will operate as described in the
