Using The Enhanced Monitoring System 4-19
a “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.
Change of Limit for
Filter Service Alarm
Example
To display a failure message after 100 days (example) of
"power-on time" the following sequence may be performed:
A. Remove power cord, then remove EMS module.
B. 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".
C. Using the following SCPI commands:
1. SENSE:TIME3:CLEAR
2.
SENSE:TIME3:RANGE:UPPER 864E6
864E6 is an example representing 8640000 or 100 days.
3. *SAV 0
You have just set the Filter Service Alarm to be active in 100
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)
VXI Slot 7 Temperature Rise is too high
4)
Fan 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
-- Enable VXI Slot 7 Temperature Rise
STAT:QUES:TEMP:ENABLE 128
