, for information on conditions that can cause a fault or alarm and
how to troubleshoot these conditions.
Component Inspection and
Maintenance
Visually inspect the major components on the control pod and fans for dirt and
damage. Dirt build-up on some components can lead to component damage or
failure. Avoid damage to the product by replacing components and/or circuit
boards with burn marks, breakage, or foil delamination. Follow the
Recommended Preventative Maintenance
on page 25 and these inspection and
maintenance instructions.
1. Review the Product Advisories
on page 11.
2. Remove power from the system. See Remove Power from the System
on
page 12.
3. Remove the drive cover. See the applicable chapter for your frame size:
• Frames 1…5 Renewal Kits Installation on page 33
• Frame 6 Renewal Kits Installation on page 81
• Frame 7 Renewal Kits Installation on page 127
4. Inspect the fan assemblies for blockage and verify free rotation. Clean or
replace as necessary. See these procedures for replacement instructions:
• Frames 2…5 control pod printed circuit board fan, see page 54
.
• Frames 1…3 heatsink fan, see page 57
.
• Frames 4 and 5 heatsink fan, see page 58
.
• Frames 4 and 5 stirring fan, see page 59
.
• Frame 6 heatsink fan, see page 97
.
• Frame 6 upper stirring fan, see page 99
.
• Frame 6 lower stirring fan, see page 100
.
• Frame 7 heatsink fan, see page 142
.
• Frame 7 stirring fan, see page 144
.
5. Inspect all control pod components, including: circuit boards, wire
harnesses, and connectors. If any components show evidence of burn
marks or breakage, replace the damaged components without further
testing.
• Frame 1, see pages 64
and 76.
• Frames 2…5, see page 69
and 77.
• Frame 6, see page 89
.
• Frame 7, see page 134
.
6. For Frames 1…5, inspect the power board. If any components, particularly
the resistors, show evidence of burn marks or breakage, replace the drive.
