The power supply can be set to start-up in remote or local mode. To change this setting, the PON REM jumper must be adjusted according to Table 2-9. You will need to remove the cover to change any jumpers. See “Changing Internal Jumpers” on page 2–8for information on how to change internal jumper settings.

See Table 2-9for the switch settings.

With the PON REM jumper open, the power supply will start up in remote mode. The gr en REM LED n the front panel will be lit, signaling that the power supply is under the control of the digital interface card. The output of the power supply is active on tartup. To promote load safety, power ON defaults are zero for the output voltage and current limit, and 110% of maximum output voltage for the OVP trip point. See Table 2-10. Refer to “Op ration” for more info mation about the interface commands listed in the table.

If the PON REM jumper is closed, the power supply will power up in local mode. Power supply control is at the front panel. During an operating session, you can oggle betwe n local mode and remote mode by using the front panel LOCAL button or sending commands as described in Table 2-10.

Note: The default setting for this jumper is open. If you require it to be closed (PON in local mode) you can obtain a spare jumper by removing the one that connects pins 11 and 12 on J2 as these pins are unused.
