Wire the Process Control and/or Automatic/Manual
Devices (if required)
Selected controller models have a high impedance input to interface
with process signals. If both manual control (controller responds to a
reference potentiometer) and process control (controller responds to
an automatic signal) are desired, an Automatic/Manual switch is
included in selected controller models.
1. Use #16 AWG unshielded cable that is twisted double conductor
with at least two twists per inch.
2. Use the appropriate tightening torque as listed in Table 32 for wire
connections to input and output terminals.
3. Wire the process control signal to terminals TB4(6+) and TB4(5-).
See Figure 37.
4. Wire the process control buffered output TB2126 to TB2326. See
Figure 37.
5. Wire the Automatic/Manual switch, if required, as shown in Figure
37.
Wire the DC Tachometer Speed Feedback Signal
DANGER
BECAUSE THE TACHOMETER IS CONNECTED THROUGH THE REGULA
TOR TO THE ARMATURE POWER CIRCUIT, THE TACHOMETER TERMINALS
ARE AT LINE POTENTIAL. DISCONNECT ALL INPUT POWER TO THE DRIVE
BEFORE SERVICING. FAILURE TO OBSERVE THIS PRECAUTION COULD
RESULT IN BODILY INJURY OR LOSS OF LIFE.
All of the controllers, except the DC271, 78, 91 and 98 or one the user
has configured for motor reversing, can utilize a DC tachometer as
speed feedback. The tachometer must have a voltage range of 18.5 to
21.0 volts per 1000 RPM or 6.5 to 7.0 volts per 1000 RPM, maximum of
37 volts at maximum speed.
1. Run the two tachometer signal leads in a separate conduit from the
motor to the controller.
2. Use #16 AWG unshielded two wire cable that is twisted at least two
twists per inch.
3. Use the appropriate tightening torque as listed in Table 32 for wire
connections to input and output terminals.
4. Connect the DC tachometer so that the tach lead connected to
terminal 519 is more positive than the tach lead connected to
terminal 419 for the desired direction of rotation. Refer to Figure 38.
