Overcurrent Protection. The output will go to the off state (0 volts and min. current) when the overcurrent protection (OCP) feature is enabled and the output is in the + CC mode. To enable the overcurrent protection mode for output 2, send:

OUTPUT 705; "OCP 2,1"

To disable the overcurrent protection mode for output 2, send:

OUTPUT 705; "OCP 2,0"

When overcurrent protection is disabled and the output is in + CC mode, the output current will be limited to and will stay at the ISET value.

Returning the Supply to Local Mode

In the remote mode (RMT annunciator on), the front panel keys have no effect on any of the supply’s outputs and only the computer can control the supply. However, you can still use the front panel display to monitor the output voltage and current or check any of the present settings (VSET, ISET, OVSET, etc.) of the selected output channel.

If you want to use the front panel keys to change the output settings, you must return the supply to the local mode. You can return the supply to the local mode (provided that the local lockout command has not been received from the computer) by pressing the LCL key. A change between the local and remote modes (or vice versa) will not result in a change in the power supply outputs. Refer to Chapter 6 for additional details on using the LCL key and operating the supply in the local mode.
