Electrical Outputs; Electrical Connections - GE T2100-ST1 Service Manual

Theory of Operation
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 factory set to 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 exceed +/- 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.

Electrical Connections

A. Input Power Header: An amp - 641968-1 four-pin MATE &
LOCK header is provided for instrument power.
B. Elevation Output Header: An amp 641968-1 three-pin MATE
& LOCK headers is provided for output power to the
elevation motor.
C. Elevation Input Header: A 3 pin 0.156" pitch header is
provided for the input from the elevation sensor.
D. Speed Input Header: A 2-pin 0.156" pitch header is provided
for the input from the magnetic reed switch speed sensor.
E. Motor Controller Interface: A 10-pin 0.1" pitch header is
provided for interfacing to the motor controller.
F. RS-232 Interface: A DB9 Connector 9-pin PC/AT Style is
provided for interfacing with the host controller.
G. USB Interface: A Mini-B right angle USB Connector is
provided for interfacing with the host controller.
