Fan Operation and Indication
Two thermostatically controlled line powered cooling
fans limit heat buildup. The primary fan energizes at
about 110 F. The secondary fan energizes at about
150 F.
Primary and secondary fan board operation is
monitored by the FPU. The following conditions
cause an alarm at the FPU:
• Any fan or fan board not receiving power.
20"
• Secondary fan turning On.
• Open cabinet door.
The single FPU at the CO has a separate power supply
for each fan board. The FPU fits into one slot of the
E220 HTU-C shelf (for HDSL applications).
The FPU is purchased separately. Information on fan
board operation and testing is in Section 3. For
additional details on the FPU refer to I&M Practice:
61150091L1-5. The FPU Practice should be on-hand
at the CO for reference during cabinet testing.
