WARNING!
!
When servicing the PCS100, dangerous voltage levels may exist. All AC and DC capacitors
should be discharged. Use extreme caution when measuring primary circuitry since this is at
line potential.
Periodic inspections of the PCS100 should be made to determine if any components, wiring, and
connections exhibit evidence of wear:
 Monitor system parameters on the control panel "Enclosure Front and Side Sections" on page 2.
 Inspect all air intakes, see "Hardware Introduction" on page 1 for further details. Make sure all air
intakes and exhaust openings are not blocked.
 Ensure the operating environment is within the parameters specified in "Environmental Consid-
erations" on page 1.
 Perform a visual inspection of all internally mounted equipment, cables, and major components.
 Inspect all terminals, cables, and enclosures for corrosion.
 Inspect all fuses.
 Inspect the operation of all safety devices (emergency stop, door switches).
 Check the filters (located behind the front door) and wash or replace as necessary. Contact your
service representative for replacement filters. To replace the filters:
a. Open the front door latch and swing the doors open.
b. Replace the filters.
c. Close the doors and secure the latch.
 Obtain all operating voltages and current readings displayed on the front display panel.
 Record the check results and any corrective actions in a suitable log.
 Record all completed inspections.
