Using The Enhanced Monitoring System 4-23
“MEAS:TIME3?” command, the “MEAS:TIME3?” command will
return a value of
0
.
Therefore, the “SENSE:TIME3:CLEAR” command should be
executed immediately after the filter is cleaned and mainframe
power is turned on.

Filter Service
Alarm Example
To display a failure message after 100 days (example) of
“power-on time” the following sequence may be performed:
A.
Locate DIP switch SW1-8 on the EMS board. Move the
switch to ON position. This allows the EMS to read the
limits at power-up from the on-board EEPROM. The
limits are read from the nonvolatile location 0. This
location is stored using the command “SAV 0”.
B.
Using the following SCPI commands:
1.
SENSE: TIME3: CLEAR
2. SENSE: TIME3: RANGE: UPPER 15.768E6.
15.768E6 is an example representing 15768000 or
182 days.
3. *SAV
0
You have just set the Filter Service Alarm to be active
in 182 days of power-on.
Interrupt
Generation
Example
As an example, suppose an interrupt is desired only when one or
more of the following conditions exist:
1) +24V Power Supply Voltage is out of tolerance
2) -12V Power Supply Voltage is out of tolerance
3) +12V Power Supply Current is out of tolerance
4) -12V Power Supply Current is out of tolerance
5) VXI Slot 7 Temperature Rise is too high
6) Fan #2 speed is out of tolerance
No other condition should generate an interrupt.
To provide for this combination, execute the following
commands:
-- 24V and -12V Power Supply Voltage only
STAT:QUES:VOLT:ENABLE 72
-- 12V and -12V Power Supply Current
STAT:QUES:CURR:ENABLE 96
-- Enable VXI Slot 7 Temperature Rise
