Instructions.
ELECTRICAL INPUTS
A) Instrument Power: 230VAC or 120VAC supplied through (2) 1/4 Amp breakers in parallel for
control board power. 230VAC or 120VAC supplied through (2) 3 Amp breakers in parallel for
elevation motor power.
B ) Elevation Sensor Input : A two wire interface for detecting the presence of a closed micro-
switch on the elevation motor.
C) Speed Sensor Input : A three wire interface for detecting the state of a magnetic reed switch on
the motor shaft.
D) Serial Port Input : An electrically isolated RS-232 serial port from the host controller.
E) USB Port Input : An electrically isolated USB port from the host controller.
F) Motor Controller Fault
–
Fault signal supplied from motor controller.
G) Voltage Selection Switch: The onboard input voltage selection switch allows the unit to be
used at 115VAC or 230VAC.
H) Emergency Stop Switch : A normally closed switch input used to switch power to the UPS
control must be rated at 24 Volts DC and 3 Amps continuous duty.
ELECTRICAL OUTPUTS
A) Elevation Motor : AC Common is permanently provided to the elevation motor. In addition,
the 120/230VAC hot input for motor elevation power is switched through a 10 Amp relay to
either the up or down input to the elevation motor.
B) Motor Controller Drive Enable Output : An optically isolated output is provided to switch on
the start input circuit for the belt drive. This output is to provide no more than 2mA.
C) Speed Output : A PWM signal for speed is provided to the motor controller. The signal is
toggled between the motor controller’s signal reference voltages (5Vdc).
The maximum current
for this output is 2mA and the maximum voltage is 15Vdc.
D) Serial Port Output : An electrically isolated RS-232 level (not to /- 10VDC) is
provided to the host controller.
E) USB Port Output : An electrically isolated USB port to the host controller not to exceed 5V or
100mA.
