Battery Pack; Blower Assembly - Motorola R-2001A Service Manual

The unit is set for 110-130 Vac operation from the factory. For operation from 1 GO-
110 Vac or 200-260 Vac, the voltage selection card must be readjusted before
connection to the power source. This is accomplished by the following procedure:
1. Remove the power cord from the rear panel connector.
2. Slide the selector card cover door over the connector area exposing the selection card and
fuse area.
3. Pull outward on the fuse ejector tab and remove fuse.
4. Remove the printed circuit board voltage selector card by pulling straight to the rear.
5. Reinsert the card at the orientation which causes the appropriate voltage range (marked
on card) to be displayed.
6. Reinstall the fuse.
7. Slide the cover plate back to the original position, connect power cord, and proceed with
system operation.
Remove the accessories to be used from the cover. Move the POWER switch to the ON position. When the
Oven Ready indicator illuminates the unit's frequency standard is stabilized and the unit is ready for use,
(instantaneous with standard TCXO).
When installing the analyzer in a vehicle, the DC supply line should be fused close to
the vehicle battery. The analyzer is protected against overload by the DC 8A fuse on
the rear of the unit, but the vehicle is not protected.
3-6. BATTERY PACK. The battery pack is attached to the rear of the analyzer with two clips and two screws.
Align and slide the mounting clips of the battery pack into the slots on the mounting brackets on the left side of
the back panel of the analyzer. Align the captive screws with the mounting holes on the right of the panel and
tighten. Connect the power plug to the connector at the top right of the rear panel.
3-7. BLOWER ASSEMBLY. The blower assembly comes from the factory wired for continuous operation.
That is, the blower will run whenever the analyzer is connected to the AC power line. If thermostatic operation
is desired the wire jumper across the thermostat in the blower assembly must be clipped out. The blower will
now run only when the back panel exceeds a preset operating temperature. Normally this temperature will only
occur in high ambient temperature conditions.
3-8. The blower assembly is mounted onto the rear of the analyzer in the same manner as the battery pack.
Align and slide the mounting clips of the blower into the slots of the mounting brackets on the left side of the
back panel. Align the captive screws with the mounting holes on the right of the panel and tighten. Connect the
power plug to the BLOWER connector on the right side of the rear panel.
