Tips and Hints
1/ make all connections as shown. Adjust feedback trimmer [FBX and FBY] to the same level as the computer input signal.
2/ Connect S1 to the blanking signal coming from the computer.
3/ Connect S2 to the blanking input of the PCAOM. Under safe conditions, the signal from S1 is passed directly out to S2. When a scan failure is detected, this connection is broken blanking the beam and the LED comes on.
4/ The safe scanning window is set by default [with trimmers Y1 and Y2, X1 and X2] to fully open at the factory. Using a full screen grid, adjust the trimmers to provide the desired windowing of the safe area.
5/ Project a small horizontal line from the computer at an unsafe size.
6/ Adjust the hysterisis control until the line disappears. Increase the size of the line and it should reappear.
7/ For maximum safety, the +30, Ground and -30 should be connected to the power supply points at the scan amps.
NOTE: Inputs should not be inverted against one another [either both X and Y must be set in normal or inverted mode with the jumpers].
