2.1 CYGNUS® basic set-up
This section provides a summary of the basic set-up and calibration of the CYGNUS control. Additional features
and options of the CYGNUS control are described later in this manual.
NOTE: The CYGNUS-DINS3 is a special version of CYGNUS intended to be used for readout only. The isolated
output of TB1 main output terminal has been converted to output a signal proportional to measured tension,
and does not provide a corrective signal.
1. The connections that are required for the basic CYNGUS system are the following: (see sections 2.0 and 3.0
for specific wiring requirements.)

115 or 230 VAC power (TB2.1 and TB2.2)

One or two load cells (TB6.1 through TB6.4, see section 6.3)

RUN/STOP using the CYGNUS internal logic supply between TB3.1 and TB3.2 (this is typically
accomplished by using a switch between these terminals) (For tension readout operation, it can be
accomplished with a jumper wire.)

TB1 isolated analog tension reference output to reading device.
2. (Not applicable for readout only operation) When using a power amplifier, set the current range jumper to the
proper setting for the clutch or brake b
eing used (refer to amplifier User’s Manual and the clutch or brake User’s
Manual for proper settings). The following is also required:

Power amplifier input (if used), 115 vac for PS-90 or 24 vac or VDC for PS-24

Output from power amplifier to clutch or brake.
3. Close the RUN/STOP circuit (TB3.1 and TB3.2) to put the CYGNUS into HOLD mode (see section 6.1.1). (For
tension readout operation, this may be accomplished with a jumper wire.)
4. Calibrate the load cells (refer to section 6.3).

During load cell calibration, be sure to select the appropriate system type (section 6.3 lists the system
type options available).
5. Turn tension on by pressing the TENSION ON/OFF key and put the CYNGUS into AUTO mode by switching
open the RUN/STOP circuit. Run the machine at a reduced line speed and observe the system. (Not
applicable for readout only operation.)
6. Refer to Section 7.0 for tuning methods that will optimize the responsiveness (Auto Tune is recommended) and
proceed to dynamically tune the system. (Not applicable for readout only operation.)
7. Basic set-up is complete. Refer to the CYGNUS instruction manual for additional features and options. Always
use the RUN/STOP feature to put the CYGNUS into HOLD mode whenever the machine is stopped to avoid a
possible high-tension condition during start-up. (Not applicable for readout only operation)
