Agilent Technologies Switch/Measure manual Safety Interlock, U T I O N

2Features and Functions

Safety Interlock

The Safety Interlock feature prevents connections to the Analog Buses if no terminal block or properly- wired cable is connected to a module (available on multiplexer and matrix modules only).

Normally, if you attempt to connect to the Analog Buses without a terminal block or properly- wired cable connected, an error is generated. You can, however, temporarily disable errors generated by the Safety Interlock feature. This simulation mode may be useful during test system development when you may not have connected any terminal blocks or cables to your module.

This feature is available from the remote interface only

C A U T I O N	The Safety Interlock feature is implemented in hardware on the modules
	and cannot be circumvented. Regardless of whether the simulation mode
	is enabled or disabled, all Analog Bus connections are prohibited as long
	as no terminal block or properly-wired cable is connected to the module.

•The simulation mode applies to the entire mainframe and cannot be selectively used on individual modules.

•When the simulation mode is enabled, the Analog Bus relays will appear to close and open as directed. For example, no errors are generated if you close an Analog Bus relay from the front panel, remote interface, or Web Interface. However, remember that the Safety Interlock feature prevents the actual hardware state of the Analog Bus relays from being changed. When you connect a terminal block or cable to the module, the Analog Bus relays will be closed.

•The simulation setting is stored in volatile memory and will be lost when power is turned off. To re- enable the simulation mode after power has been off, you must send the command again.
