The stepper motors (X-motor and Z-motor or Rotation Motor)
are powered by 12 VDC (approximately 0.4 amp). The Y-motor
is driven by 120 VAC (approximately 100 ma). Power to the
Y-motor and the Rotation motor is supplied via connector
P8/J8. Power is sent to the X-motor through connector P9/J9.
Power at 120 VAC for the Recirculation Pump, for the
Water-Input Line, Solenoid Valve, and for the Heater Element
and Blower in the Dryer Assembly are sent through connector
P10/J10. All 120 VAC, 50/60-Hz outputs from the Computer
Control Board (including the Y-motor power over P8/J8 are
driven by triac networks that are activated by a logic-low
signal on the Computer Control Board. The 12 VDC stepper
motors are controlled by signals from the Computer Control
Board.
Dryer
The Drying Station blows heated air over the slides. The Dryer
Assembly (Figure 3.5) is comprised of the following
subassemblies:
•
Dryer Fan
•
Dryer Element (heater)
•
Temperature Sensor
•
Thermostat
•
Stainless Steel Well Frame
The Dryer Blower (fan) is 120 VAC, 4W unit. During a
programmed sequence the Blower is turned ON by the
microprocessor as the Robotic Arm starts toward the Drying
Station. In the manual mode, the Blower is turned ON as the
Arm is lowered into the well. A semiconductor sensor on the
wall of the well opposite the Blower provides temperature
data. The Dryer Element is a nichrome coil strapped on a
ceramic core. The temperature regulator is factory calibrated
and maintains the nominal set temperature measured at the
sensor.
