Section 4
Bench Testing
Motorola’s recommended procedure for placing a new MBV3-100* into service is to fully test it
on the bench before it is field installed. There are specific alignment procedures that ensure
proper functioning of all components and simplify final installation. If the MBV3-100* is
properly aligned on the bench, only minor adjustments may be required in the field.
The following subsections provide instructions to bench align the MBV3-100*.
Before You Begin
The MBV3-100* is shipped with a 20 ampere blade-type fuse in all ports of the amplifier module
for overcurrent protection.
CAUTION!
To avoid applying 60/90 VAC to the test equipment during testing, remove the fuse from the connected
output port (
F2, F3, or F4) illustrated in Figure 2-9. Terminate all unused ports.
Open the housing and remove the electronics chassis cover. Refer to your system drawings or
records to confirm the presence of the required options as described in Section 2, “Overview,”
Options and Accessories.
Reinstall the electronics chassis cover and torque the screws to 10–12 in-lbs.
