Maintenance— 2230 Service
changes may result in changes of case styles or lead
configurations. If the device in question does not appear to
match the configuration shown in Figure 9-2, examine the
associated circuitry or consult the manufacturer’s data
sheet.
The center signal leads may be connected to the out
side ground leads of P2111 and P2112 by using four
1-inch long number 22 tinned copper wires (two wires for
each connector). Bend the wires in a U-shape and insert
the wires between pins 1 and 2, and between pins 3 and 4
of the connectors (see Figure 6-2).
Multipin Connectors
Multipin connector orientation is indexed by two trian
gles; one on the holder and one on the circuit board. Slot
numbers are usually molded into the holder. When a con
nection is made to circuit board pins, ensure that the index
on the holder is aligned with the index on the circuit board
(see Figure 6-1).
Storage Board Latch
W A R N I N G
Turn off POWER switch before placing the Storage
circuit board in Servicing Position.
While servicing the interior of the instrument, the
Storage circuit board may be latched in the Servicing Posi
tion. See the "Storage Circuit Board in Servicing Position”
in the “ Removal and Replacement Instructions” part of
this section. The two signal leads of the four-wire connec
tors P2111 and P2112 need to be grounded when discon
nected from the Storage circuit board. Grounding the
signal leads of P2111 and P2112 permits the VERTICAL
POSITION controls to work properly.
Analog Isolation
The digital portion of the instrument may be isolated
from the analog portion of the instrument. Use of this pro
cedure enables disabling and isolation of the digital portion
of the instrument while permitting troubleshooting on the
analog portion.
