5.4.1

VISUAL

Inspect unit.

Check for damage or missing parts.

more power supplies are available, they may

connected to the other inputs (5112, J113, 5114) on

the SAP1626, however the rest of this procedure as-

sumes that one power supply is used. Connect a

BOP220 as shown in Section 2.

5.423 (OPTIONAL-When triple current limiter is

installed). Power up the

"TW"

power supply and

measure the output of each section of the triple cur-

rent limiter board. Output

can

be measured at the

fuses of the triple current limiter Al. Output should

read

+2 volts DC.

5.423 Check voltage at the bus connecting pins 1-3

of the thumbwheel switches. Voltage should

volts DC on both the upper and lower

thumbwheels.
