Table 2.7 outlines the light sensors and corresponding ticket path for LEDs D13 - D20.
Figure 2.11 shows the location of the diodes and the transistors in the ticket channel of the SST/
HP-1 Transport.
Figure 2.12 shows the location of the diodes and the transistors in the ticket channel of the SST/
HP-4 Transport.
D34 Power Distribution Relay for Burster is enabled.
1 Light glows dimmer than for the other LEDs.
2 In Single Step Mode, software controls the motor speed.
3 Light appears dimmer than for the other LEDs.
4 In VCO, hardware controls the motor speed.
