3BUS 208 000 R1301186 Maintenance Procedures

Air Purge Filter Inspection

The Scanning Platform requires a constant flow of filtered air to keep the electronics

and mechanisms at a safe temperature and to prevent contaminants from entering

the sealed platform.

If the platform is utilizing DC motor cooling air from the mill air system, there are

no extra filters needed.

If the platform is using the ABB supplied high capacity purge blower (Part Number

101495-006, the filters need to be cleaned periodically to maintain good air flow.

The frequency of cleaning the filters depends upon mill conditions. The presence

of good air flow is easily detected by opening the doors on the idler side of the

Scanning Platform.

The high capacity purge blower is intended to provide better SP Frame reliability

under all environmental conditions. The circuit breaker is rated at 15.0A for the

high capacity purge blower. The high capacity purge blower draws between 5 and

9 AMPs at 230 VAC during normal operation. The highest current will be observed

when the damper is fully open.

Purge Blower Replacement Process

Note: Purge blowers used before October 1995 used a low capacity purge

blower, Part Number 101495-003. This item is no longer being used.

A high capacity purge blower, Part Number 101495-006 is now being

shipped and replaces the low capacity purge blower.

If the low capacity purge blower fails, you will need to order the high capacity

blower assembly. The following assemblies are available for specific application

requirements:

• 123595-008 Purge Blower Assembly without cabinet and with

High Capacity Purge Blower

• 127323-011 Blower Assembly without cabinet and with

High Capacity Purge Blower

• 127323-012 Blower Assembly with stainless steel cabinet and

High Capacity Purge Blower

Note: Some earlier shipments of the high capacity purge blower contained

the wrong circuit breaker. If you replaced the low capacity purge

blower with the high capacity purge blower, check the circuit breaker

for the correct rating. If you are experiencing startup or run trips,

check the circuit breaker rating. If incorrect, order the correct rating,

15.0 A, ABB Part Number 014847-108.
