Defining the OTP Mode | Xantrex Technology XTR 850 WATT SERIES

Using Over Temperature Protection Lock (OTP)

Using Over Temperature Protection Lock (OTP)

The OTP lock protects the power supply in the event of an over temperature alarm. This alarm could be caused by ventilation restriction or overheating due to fan failure.

Two modes are available:

• Auto recovery (OTP OFF) where the power supply turns on again

after cooling down.
• Latch mode (OTP ON) where you will need to reset the unit by
turning the front panel power switch to Off and then On again.
If the OTP is activated, the main output will turn off and PRO O7P (over
temperature protection) will blink on the display. The OTP alarm is an
alarm that will auto recover when the temperature falls back into normal	3
bounds.	3

Defining the OTP Mode

To define the OTP lock:

1.Turn the 9-position mode control to the PRT position. PrO OUP is displayed.

2.Turn the rotary Adjust/Enter control until PRO O7P is displayed.

3.Press the rotary Adjust/Enter control to display O7P ON or OFF.

4.Turn the rotary Adjust/Enter control to change to On or Off.

5.Press the rotary Adjust/Enter control.

The SCPI command (s) for these instructions are:

[:]SYSTem[<channel(s)>]:PROTection:LATCh

Resetting in Latch Mode

To reset the power supply if the OTP alarm is tripped and the OTP mode is set to On (latching enabled), press and hold the rotary Adjust/Enter control for approximately 3 seconds.

The SCPI command (s) for these instructions are:

[:]OUTPut[<channel(s)>]:PROTection:CLEar

[:]SYSTem[<channel(s)>]:PROTection:LATCh
