Warner Electric B30 Single Range Tensioncells - Manual (Page 8)

8 Warner Electric • 800-825-9050 P-2012-4 • 819-0404
Mechanical Alignment
Align the sectional measuring roll to avoid any
mechanical binding or friction. The measuring
roll must be level and perpendicular to the path
of the strip material for accurate measurement.
The Mechanical Stops are fixed for the required
travel of the Load Table.
Electrical Installation
(Read the entire electrical wiring procedure
before proceeding.)
1. Turn off all electrical power to the loadcell.
2. Use twisted four conductor signal cable,
Belden 9402 or equivalent, in grounded steel
conduit from the LVDTs to the control panel.
3. Observing correct polarity, connect the
positive (+) input lead to Pin A and the
negative (-) input lead to Pin B.
(See Figure 9)
4. Connect the positive (+) output lead to Pin D
and the negative (-) output lead to Pin C.
(See Figure 9)
5. Repeat Steps 1 through 4 of the electrical
wiring procedure for the Tensioncells
mounted on the other end of the measuring
roll.

NOTE: Warner Electric loadcells are calibrated
for 24 volt DC input voltage to provide a 0.5 to
6.5 volts DC output signal.
Electrical Zero Adjustment
(Read the complete Electrical Zero Adjustment
procedure before proceeding with the
adjustment.)
1. Disengage strip from the measuring roll so
that no tension force is applied to the
loadcell.
2. Connect a voltmeter to Pins C and D
(See Figure 9)
8. Position the roll with the Tensioncells on the
machine and fasten with the mounting bolts.
9. Rotate the Tensioncells to the proper
mounting angle and tighten the mounting
bolts.
10. Lock the locating pad for each Tensioncell
against the machine frame using the 1/4-20
x 1/2 socket head capscrew.
11. Tighten the shaft in the mounting block on
the W1 unit. (The shaft end at W2 is left free
to allow it to move as the shaft expands with
temperature changes).
