This page provides a summary of the basic set-up and calibration of the Spyder control in load cell mode.
Additional features and options of the Spyder control are described later in this manual.
Refer to the Load Cell screen flowchart drawing number 850B327 for a navigation aid.
1. The connections that are required for the basic Spyder system are the following: (see Sections 2.0, 6.0 and
Figure 5 for specific wiring requirements.)
24 VDC power (Term.6 and Term.7)
Earth ground (Term. 8)
One or two load cells (Term.23 through Term.26)
RUN/STOP using the Spyder internal logic supply between Term.9 and Term.11 (this is typically
accomplished by using a switch between these terminals)
E-Stop jumper in place between Term.10 and Term.11. (This is supplied by default from the factory)
Analog control output to clutch or brake amplifier, current-to-pressure transducer, motor controller, etc.
(Term.30 to Term.31, refer to Sections 5.1 and 5.3 for output configuration). The Spyder inputs and
outputs are referenced to Earth ground and the negative of the 24 VDC power.
2. When using a power amplifier, set the current range jumper to the proper setting for the clutch or brake being
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.
The Spyder output is referenced to Earth ground and the negative of the 24 VDC power.
3. Close the RUN/STOP circuit (Term.9 and Term.11) to put the Spyder into HOLD mode (see Section 5.2.1).
4. Using the Configure menu select "Control Type = Load Cell" and appropriate system type. See Section 6.2.2
for the Configure menu and Figure 6 for an explanation of the point-to-point types.
5. Calibrate the load cells (refer to Section 6.3).
6. Turn tension on by opening the TENSION ON/OFF circuit (Term.13 and Term.11), put the Spyder into AUTO
mode by opening the AUTO/MANUAL circuit (Term.12 and Term.11), and put the Spyder in RUN mode by
switching open the RUN/STOP circuit. Adjust the tension setpoint using a potentiometer (Term. 15 through
Term.17). Run the machine at a reduced line speed and observe the system.
7. If the system is unstable, go to the Quick Stabilize menu (Section 6.4.1) and press the
(down arrow) to begin
stabilizing. Use the
←
(left arrow) and
→
(right arrow) in the following screens to tune the system.
8. Refer to Section 6.4.2 for tuning methods that will optimize the responsiveness.
9. Basic set-up is complete. Additional features and options are described later in this manual. Always use the
RUN/STOP feature to put the Spyder into HOLD mode whenever the machine is stopped to avoid a possible
high-tension condition during start-up.
