Remote Inhibit (RI) Function Switches

This function allows the power module outputs to be shut down from a signal (low-true TTL level) applied to the mainframe INH input. The INH input is internally connected to the mainframe remote inhibit (RI) line. This line is normally high and is distributed to all power modules in the mainframe. An external switch closure that shorts the mainframe INH input is detected by the power module as an RI signal.

Note

See "Chapter 3 - Connections" in the mainframe Installation Guide for more information on external INH

 

connections.

Within each power module, the RI signal is applied to the RI section of the configuration switch (see Figure 2-2). The RI switch allows you to select one of the following responses to the RI input signal:

Switch Setting

RI Action

RI disabled

The module ignores the RI input signal

RI latched

The module shuts down and remains shut down when the RI signal goes true. A

 

software command is required to restore the output (see "Chapter 4 - Basic

 

Power Module Commands").

RI nonlatched (real-time)

The module shuts down only as long as the RI signal is true (TTL low). The output is restored when the RI signal goes false (TTL high).

Display Function Switch

A single switch configures the display function. Use it to permanently turn the power module voltage and current display indicators off or on (the annunciators are unaffected by this switch). If the switch is left in the ON position, the display may be turned on or off by software commands (see the power module Programming Guide).

Calibration Function Switches

The calibration switches allow you to select one of the following modes of calibration:

Switch Setting

Calibration Mode

Normal calibration

Permits normal calibration (requires entry of a password)

Factory calibration

Restores original factory calibration (no password is required)

Inhibit calibration

Prevents calibration

The factory position is useful if the power module has been miscalibrated or if the calibration password has been lost.

Power-On Function Switch

This switch allows you to determine the operating state of the power module when it is turned on. With the switch set to 1 (on), the power module will be in the factory-default reset state (see *RST in "Chapter 3 - Language Dictionary" of the power module Programming Guide). If you move the switch to 0, the power module will turn on to whatever state you save to memory location 0. See "Chapter 4 - Basic Power Module Commands" for more information.
