Preliminary Checks

Power-On
Raise the control panel lid and set the power supply switch to ON. Verify
the green RUN LED on the CPU Board (located in the middle of the tub) is
lit. Set the power switches on the Switcher Frame Power Supply to the ON
position. Verify that the power supply voltage LEDs on the front of the
frame power supply are lighted and the fan is on. If any of these conditions
are not present, turn the system off and refer to Section 5, Diagnostics and
Troubleshooting.
NOTE:
Refer to the illustrations at the beginning of this section (Installation) for
the component locations described here.
A successful power-on is indicated by:
■All green LEDs on the Frame power supply are on.
■The green RUN LED on the Control Panel CPU Board is on.
■The Control Panel Menu Display is on and displaying the
Model 2200 sign-on message.
Check the following indications inside the front door of the A and B
Frames:
■The +5V RUN lights at the top of each module in the A & B Bays of the
switcher frame are lit.
■The rear module power indicators on the Sync Generator Module in
Slot A10 are lit for each module present in the rear frame.
Set the FIELD RATE and LOCK FREQ switches on the Sync Generator
Module (064801) in Slot A10 to the correct settings for your facility:
■S1 - FIELD RATE to either 60 or 50 Hz
■S2 - LOCK FREQ to 13.5 Mhz
CAUTION
To meet RF/EMI specifications and to ensure proper cooling, the door on the front
of the switcher frame must be closed.
NOTE:
Maintenance Personnel should be familiar with the Control panel and its
usage. For information and reference, see the Model 2200 Operator’s Guide.
When the system is turned on, preset parameters contained in non-volatile
RAM are loaded into the working area of memory. This provides a preset
copy and a working copy of the parameters. The working copy is used for
normal operation and the preset copy is used if a problem occurs with the
working copy.
Changes can be made to the working copy without affecting the preset
copy. When power is removed and reapplied, parameters revert to those
contained in the preset copy.
