transducer not OK condition. With this option, the recorder output will clamp to either
+2mA or +4mA (user selectable) when a transducer is not OK.
TRIP MULTIPLY - The Trip Multiply function multiplies setpoints by 2X or 3X in response to
an external contact closure through terminals on the Power Input Module. When Trip
Multiply is active, the BYPASS LEDs flash and the TRIP MULTIPLY LED on the System
Monitor is on. The front panel meter and recorder outputs could saturate in this mode.
Setpoints beyond 1/3 to 1/2 of full scale may exceed OK limits when used with trip
multiply.
SELF TEST - The monitor has three levels of self test: Cyclic, Power-up, and User-invoked.
Power-up self test is performed automatically each time the monitor power is turned on.
A series of basic tests and transducer OK tests are performed.
Cyclic self test is performed automatically during monitor operation. Errors
encountered during cyclic tests disable the monitor and flash an error code on the LCD
bargraph display. If the error is intermittent, the monitor will return to operation and the
error codes will be stored for retrieval during User-invoked self tests. If the channel is OK,
the monitor indicates that error codes have been stored by flashing the OK LED at 5 Hz.
User-invoked self test performs Power-up self test and lets you read and clear error
messages that were stored during Cyclic self tests. Stored errors are annunciated by the
OK LEDs flashing at 5 Hz and the error codes displayed on the front panel LCD bargraph.
Refer to the Self Test section in this manual for further details.
ERROR CODES - Error codes are displayed on the Monitor's LCD display. The error code
display is distinguished from normal monitor operations by a fragmented scale
representation. Refer to the Self Test and Error Codes sections of this manual for more
details.
The monitor continuously indicates acceleration or velocity for Channels A and B.
