Indicators

D1 (LCD Supply) When lit, this green LED indicates that the 12 vdc supply voltage is

available to light the LED backlight.

D2 (Logic Supply) When lit, this green LED indicates that the 17 vdc supply voltage is

available to power the CPU board.

D3 (Intrfc Supply) When lit, this green LED indicates that the 17 vdc supply voltage is

available to power the Interface board.

D4 (Pump Supply) When lit, this green LED indicates that the 32 vdc supply voltage is

available to power the DD-1 Pump.

Schematic Description

Two isolated DC supplies are provided.
Bridge rectifier BR1 rectifies 14VAC to an unregulated 17VDC. Capacitor C1 provides
filtering. Fuse F1 limits the combined current demand from the LED board, CPU board, and
LCD/Touchscreen. LED D2 indicates that an unregulated 17 VDC (approximately) is
available when illuminated for the LED board, CPU board, and regulator U1. Capacitors C4
& C5 provide input filtering for regulator U1 for better line regulation. Capacitor C3
provides output filtering for regulator U1 for better load regulation. LED D1 indicates that
12VDC for the LCD/Touchscreen is available when illuminated.
Bridge rectifier BR2 rectifies 14VAC to an unregulated 17VDC. Capacitor C2 provides
filtering. Fuse F2 limits the current demand from the Interface board. LED D3 indicates that
an unregulated 17VDC is available when illuminated. This supply is isolated and used for
incoming encoder and scanner signals on the Interface board. Fuse F3 limits the current
demand from the DD-1 Pump. Diodes CR3 and CR4, along with capacitors C6 and C7, form
a voltage doubler and filter the output at J7 to about 32 vdc.
