Purpose: To prevent Framing Errors due to low +5V battery supply.

Status: Mandatory.

Circuit Card: FD 267 and FD237 Sprocket Pulse Shaper
 

Parts: One 4.7 ohm resistor 1/4W
 

Description:

Turn off FDL power.
 

Remove FD267 (or FD237 card) Sprocket Pulse Shaper.
 

Locate P/N of card on the PC card.
 

Depending on the P/N change the following resistor:
 

FD267:
 

P/N 0-130-582-800 Change R14 to 4.7 from 47 ohms.
 

P/N 0-130-582-700 Change R30 to 4.7 from 47 ohms.
 

FD237:
 

P/N 0-130-581-000 Change R14 to 4.7 from 47 ohms.
 

Return to FDL install shield if removed.
 
 

The +5 volts on the FD234 Film Timer should be +5v -.0/+.1 volts.

Set with pot "+5V" on card.
 
 

If this +5v is noisy (more than +/- .3v on a scope) replace the 1,000uf and 3,300uf cap on the FD234.
