Abbott VP 2000™ Processor Service Manual
30-608308//R1—September 2008
The computer control board generates signals that are sent to
drive solid state relays that control power to the pump and
solenoid valve. When running a program, fluid flow begins as
the Arm starts towards the Wash Bath. In manual mode, fluid
flow begins as the Arm lowers into the bath. Flow continues as
long as the Arm is lowered at the Wash Bath and for three (3)
minutes more after the Arm leaves that station.
The pump used is a magnetically driven pump with no seals. It
is 120 VAC, unit that produces a flow of about 100 gallons per
hour. Note that plastic components in the pump can “freeze
up” if it is operated without fluid for longer than 30 minutes.
Power Supply
The Abbott VP 2000 Processor may be ordered from the factory
as 117 VAC, 60-Hz units, 100 VAC 50-Hz, or as 230 VAC,
50/60-Hz units. Peak power consumption is 600 Watts and
occurs when the Heater Elements are operating.
The unit operates at line voltages from 90 to 110 VAC at
50/60-Hz, 108 to 126 VAC at 60-Hz, or 207 to 258 VAC at
50/60-Hz A voltage-suppressor filter on the power input line
and a transient-surge suppressor on the Computer Control
Board protects against voltage spikes. These measures protect
the equipment significantly, but might not prevent a major
transient surge, say during an electrical storm, from affecting a
program in process at that time.
Input Power goes to the ON/OFF Switch, which is also a 6 amp
circuit breaker (7 amps on 100 VAC uints and 4 amps on 230
VAC units). Input ground is to the chassis. Power reaches the
Computer Control Board through connector J10/P10. All
system power, other than for the Exhaust Fan, is routed thru
the Computer Control Board. Power to the Exhaust Fan is
obtained directly through connector J10/P10 via a shorting
jumper.
From the Computer Control Board, 117 VAC is sent to the 12
VDC switching Power Supply. Twelve (12) volts from the
Power Supply is sent back to the Computer Control Board
through connector J101/P102 on the Power Supply; a regulator
on the Computer Control Board produces nominal 5V and 8V
signals.
