Why am I getting a 5074 event code?
The instrument provides an interlock circuit on the rear panel. You must enable this circuit in order for
the instrument to set source voltages greater than ±42 V DC. If you try to assign a high-voltage output
and turn the source on when the interlock is not asserted, you see event code 5074, "Output voltage
limited by interlock."
The Model 2460 is provided with an interlock circuit that must be positively activated in
order for the high voltage output to be enabled. The interlock helps facilitate safe operation
of the equipment in a test system. Bypassing the interlock could expose the operator to
hazardous voltages that could result in personal injury or death.
If the safety interlock is not asserted and the source is turned on, the following actions occur:
•
The nominal output is limited to less than ±42 V.
•
The front-panel INTERLOCK indicator is not illuminated.
To recover from this error, properly engage the interlock using a safe test fixture before turning on the
Model 2460 output.
