Over Voltage Protection (Ovp) Calibration - Xantrex ENET-XFR Operating Manual

Over Voltage Protection (OVP) Calibration

TM-XR9B-01XN
We recommend that you perform OVP calibration every six months.
Connecting a digital voltmeter as in
optional.
1. Disconnect all loads from the power supply.
2. Ensure that jumper J65 on the interface PCB is CLOSED to enable
remote OVP calibration (Jumper J65 is closed at the factory). See
Figure 2-3, "Ethernet/RS-232 Interface PCB" on page 2–6
location on the PCB of jumper J65.
3. Activate calibration mode by sending command CMODE ON or
CMODE 1 to the power supply.
4. Send the command OVCAL to the power supply. The ADDR LED
will light during OVP calibration. Calibration is complete when the
ADDR LED turns off. This may take a few minutes.
5. Use the OVSET, OVSET?, and VSET commands to trip the OVP
level, confirming that the calibration was successful. When you trip
the OVP level, the red OVP LED will light and the voltage will drop
to zero. Send the command RST to clear the OVP condition. Refer to
the OVP program accuracy specification in
6. Turn off calibration mode by sending the command CMODE OFF or
CMODE 0 to the power supply.
