Current Leakage Measurements (90479-A/B/C only)
Refer to the
Ultraview SL Operations Manual
(P/N 070-1150-xx),
located on CD-ROM P/N 084-1101-xx, for the specific type of safety
analyzer being used. Follow the instructions for ground (earth)
leakage and chassis (enclosure) leakage.
1
Remove power from the module housing and check the AC
Power cord for damage.
2
Test power cord resistance between the ground connector on the
end of the cord and the ground stud on the mainframe.
Resistance should be less than 200 milliohms.
3
Test the 90479-A/B/C module housing in normal and simple fault
conditions.
Battery Backup Test
This test checks the performance of the module housing backup
battery that powers each receiver module in the event of a power
failure. This backup battery should support receiver operation for a
minimum of 10 minutes without data loss.
To conduct the module housing battery backup
test
1
Check the battery backup system, including the charging
system and batteries. Visually inspect the battery for any signs
of corrosion, leakage, damage or signs of swelling.
2
Activate all the receivers in the module housing and set them
to receive data from their transmitters. Store several minutes of
data in each receiver.
3
Unplug the module housing’s AC power cord from its power
source for several minutes (up to 10 minutes). Do not turn OFF
either power switch.
4
Observe the displayed telemetry channels on the monitor. All
channels should remain displayed on the screen without
interruption.
5
Plug the power cord back into the AC power source and
observe the telemetry channels on the monitor. All channels
should remain displayed on the screen without interruption.
Note:
The battery should be replaced at least every 12 months
regardless of operation.
Caution:
Patient data could be lost during this test. Do not conduct the
battery test on systems which are currently monitoring patients.
