8.1 ELECTRICAL CONNECTIONS
Figure 16 shows the complete connections that are required for the Spyder open loop tension control system. The
minimum connections are:
24 VDC power
Earth ground
Diameter sensor with voltage output proportional to diameter. Input between Term.38 and 39.
For unwinds the diameter sensor should monitor the unwind diameter and for rewinds the rewind diameter.
RUN/STOP switch using the Spyder internal logic supply
E-Stop jumper between Term.10 and Term.11 (This is supplied by default from the factory)
Potentiometer (1K to 10K ohm) for tension setpoint. Alternately, Setpoint Tension can be set using the Ethernet
port. Choose the Setpoint Source from the Configure menu.
Output to clutch or brake amplifier, current-to-pressure transducer, motor controller, etc.
Route power wiring away from sensor and control wiring. Run all wiring in shielded cable, except for the 24 VDC
power which may be twisted pair. Connect cable shields to the terminals provided. Maximum shield length and
maximum length of wires outside of the shield is 1.5 inches (38 mm).
The signal inputs and outputs are Earth ground referenced. The power input circuit is not isolated, since the
negative lead of the 24 VDC power input is Earth ground referenced.
An inverse diameter output is available on the meter output to control the speed of rewinds to reduce the heat
dissipation in a rewind clutch. See Figure 16.
8.2 SOFTWARE CONFIGURATION FOR OPEN LOOP TENSION SYSTEM
Refer to the Open Loop Tension screen flowchart in drawing number 850B327 for a navigation aid.
8.2.1 OPERATOR LOOP MENU
This section describes all the screens in the Operator Loop menu. All
screens are display only except for Percent Taper.
8.2.1.1
TENSION
This screen shows the actual tension in numeric and bar graph form. This will be different from the setpoint tension
when taper is enabled. The lower left character displays the status of the Spyder.
E = E-Stop
H = Hold
s = Start
A = Automatic (Run)
S = Stop
M = Manual mode
OFF = Tension OFF
8.2.1.2
PRESENT DIAMETER
Present diameter displays the current diameter being input on Term. 38. See Section 8.3 for calibrating diameter.
8.2.1.3
SETPOINT TENSION OR CORE TENSION
Setpoint Tension (or Core Tension with taper) is set by the voltage on Term.16 (Setpoint Source = Analog) or via
the Ethernet port (Setpoint Source = Ethernet). Setpoint Source is set in the Configure menu.
8.2.1.3.1
SETPOINT TENSION (No taper tension)
Display only.
8.2.1.3.2
CORE TENSION (With taper tension)
Display only. This is the setpoint at core diameter only. At other diameters the setpoint is less than the core setpoint
if Taper Percent > 0.
