Using
as a guide, replace one of the four reject load assemblies or one of
the two reject load/splitter interface assemblies as detailed in this section. Identify the affected reject
load, possibly named in an alarm reference and then replace it, as follows:
RF Drive Splitter A27/A127 - accepts two of the six 5 kW reject power inputs (RF power modules 1-
2 and 3-4) (see
“5 kW or 10 kW Reject Load Replacement” on page 4.1.58
)
4-Input Reject Load A29/A129 - accepts four of the six 5 kW reject power inputs (RF power
modules 5-6, 7-8, 9-10 and 11-12) (see
“5 kW or 10 kW Reject Load Replacement” on page 4.1.58
)
4-Input Reject Load A31/A131 - accepts the three 10 kW reject power inputs (RF power modules 1-
4, 5-8 and 9-12) (see
“5 kW or 10 kW Reject Load Replacement” on page 4.1.58
2-Input Reject Load A13/A113 - accepts the 20 kW reject load power input (RF power modules 1-8)
and the final (30 kW) reject load input (RF power modules 1-12) (see
)
Reject Load/Splitter Interface Assembly (A28 and A30/A128 and A130) - see
