TRACKMASTER
HARDWARE REQUIREMENTS
The SPS electronics hardware consists of one electronic control board.
ELECTRICAL INPUTS
A) Instrument Power: On 230VAC or 120VAC supplied through two 1/4 Amp breakers
in parallel for control board power. On 230VAC supplied through two 2 Amp breakers,
or 120VAC supplied thru two 1amp breakers, in parallel for elevation motor power.
B ) Elevation Sensor Input : A two wire interface for detecting the presence of a closed
microswitch on the elevation motor.
C) Speed Sensor Input : A two wire interface for detecting the state of a magnetic reed
switch on the motor shaft.
D) Inverter Fixed Reference Voltage : A 10 Volt reference is provided by the inverter
drive.
E) Serial Port Input : An RS-232 level input provided by the host controller.
F) Voltage Selection Switch : The onboard input voltage selection switch allows the unit
to be used at 115VAC or 230VAC.
G) Emergency Stop Switch : A normally closed switch input used to switch power to the
SPS control must be rated at 24 Volts and 2 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) Inverter Drive Enable Output : An optically isolated output is provided to switch on
the start input circuit for the inverter belt drive. This output is an emitter - collector pair
that is to provide no more than 2mA.
C) Speed Output : An isolated analog voltage reference for speed is provided to the
inverter. The signal is proportional to the inverter's fixed voltage reference and includes
a 47K impedance. The maximum current for this output is 1.8mA and the maximum
voltage is 15VDC.
D) Serial Port Output : An RS-232 level (not to exceed +/- 10VDC) is provided to the
host controller.
