17. The Model 3000 autotimed Analog input module accepts input video within 17 ps of the Input Reference Video outside of this range is not auto timed The autotimed module also corrects input SC H subcarrier to horizontal phase errors within the range of 170 degrees It corrects SC H error by repositioning the video with respect to sync For example an input SC H error of 170 degrees will result in a 132 ns horizontal shift a 10 degree error will result in an 8 ns shift approximately 1 8 pixel Because SC H errors are corrected by repositioning video a potential problem can occur when match frame editing In order to match into previously recorded material SC H errors of the playback and record machines must be controlled to provide consistent SC H phase This action is necessary because SC H errors shift the picture To ensure an accurate match all sources must remain consistent NOTE Any SC H error in the Input Reference to the switcher will skew the input SC H acceptance window and alter the sampling phase of the manual timing mode of the autotimed module Crosspoint Name Displays Model 3000 3 only Installation of Options The following pages describe installation of several options If you are not installing any of these options at this time turn now to Configuring Your System Software at the end of this section Crosspoint Name Displays Model 3000 3 only The Input Display Board Option is install

In a redundant power system the two 5 Volt supplies must be of the same make and the two Multi Output supplies must be of the same make The 5 Volt and Multi Output supplies however may be of different makes This means that if you need to replace one power supply assembly in a redundant power system you must either replace that supply with one of the same make or replace both supplies that operate in parallel Check to see that your replacement is compatible in a redundant system and if necessary contact Grass Valley Customer Service NOTE In a non redundant power system if both power supply units one Multi Output and one 5V in the single power supply frame are Todd supplies the frame can be wired to operate on 110 volts as described in the Installation information of this Addendum Configurations Each power supply comes as a complete assembly sled that must be replaced as a unit As viewed from the rear of the frame the 5 Volt supply assembly is located in the compartment at the right side of the chassis and the Multi Output 13V 13V 5 2V 48V supply is located in the compartment at the left Procedures The following procedures one for the Multi Output supply and one for the 5 Volt supply describe replacing Pioneer power supply assemblies with Todd power supply assemblies Section 4 Maintenance For any of the other three possible replacements replacing a Pioneer unit with a Pio
