The table control board is a newly designed part, which is fixed on the dock frame shipped
with the fixed table package.
• PS for PHPS-LITE2 supplies DC 42V power as the input of table control board through SCIF
board. Then table control board outputs two direction power to the electrical actuator in
the fixed table. When the up or down foot pedal is pressed down, the table will move up
or down. And when the Up limit Switch or Down limit Switch is activated, the table will
stop.
• Table control box transfers the table vertical position information to SRI. When the table
is on the highest position, SRI will output Enable signal to PHPS Lite2 to enable the
longitudinal movement of the cradle. And it receives 8V power from the SRI for its logic
circuit working. The signal ground is connected to table control box shell through fasten
screw.
