* NOTES:
|
||
|
|
*
|
||
|
|
* REVISIONS:
|
||
|
|
* ker02DEC92: Initial breakout of sensor classes into indiv files
|
||
|
|
* ker04DEC92: Initial Filling in of Member Functions
|
||
|
|
* SjA11Dec92: Validate method now returns ErrNO_ERROR rather than VALID.
|
||
|
|
* pcy17Dec92: Now I do StateSensor::Validate before doing my own.
|
||
|
|
* pcy16Feb93: No longer need to register for UPS_STATE
|
||
|
|
* pcy16Feb93: Get transfer cause and ignore if self test
|
||
|
|
* ajr22Feb93: included utils.h
|
||
|
|
* jod05Apr93: Added changes for Deep Discharge
|
||
|
|
* cad09Sep93: Fix for lights test causing events
|
||
|
|
* pcy09Sep93: Check LINE_AVAILABILITY to make sure line is bad
|
||
|
|
* pcy10Sep93: Hopefully this works now
|
||
|
|
* pcy18Sep93: Cleaned up line condition handling
|
||
|
|
* pcy20Sep93: handle line fails during tests and sim pwr fail
|
||
|
|
* pcy12Oct93: 2 ABNORMALS to cause a line bad (fixes LF during cal)
|
||
|
|
* pcy13Apr94: Use automatic variables decrease dynamic mem allocation
|
||
|
|
* djs16Mar95: changed upsstate.h to sysstate.h
|
||
|
|
