FORM NO. L-20292-C-0700
NOTE
If using one MB Tension Sensor, Terminals 5 and 6
must be jumpered together.
NOTE
Make sure the sensor roll is mounted to the MB
Tension Sensor as described in the MB Tension
Sensor Instruction Manual.
1. Set the Power Switch to ON.
2. Make sure the web has been removed and no other
objects are sitting or resting on the sensor roll.
3. Rotate both S1 and S2 counterclockwise to minimum
(See Figure 7).
4. Connect a voltmeter to TP7 (COM) and TP1 (See Figure 7).
5. Rotate Z1 to read 0.00VDC at TP1 (See Figure 7).
6. Connect a voltmeter to TP7 (COM) and TP2 (See Figure
7).
7. Rotate Z2 to read 0.00VDC at TP2 (See Figure 7).
CALIBRATION FOR MB STYLE LOAD SENSORS
NOTE
Prior to calibration, make sure jumpers J3 and J4 are set to the No. 3 position for MB Sensors.

SPAN ADJUSTMENT (WITH ONE MB TENSION SENSOR)
NOTE
Before making any Span adjustments, the output
voltage level needs to represent the tension levels
required. The maximum tension level needs to be
calculated (Example: Maximum Tension = 100 Lbs.).
NOTE
When using one MB Tension Sensor, Terminals 5 and
6 must be jumpered together.
1. Thread a rope or narrow web over the Sensor Roll in
the normal path. Be sure the rope or web is at the
center of the Sensor roll; then, hang a known weight
(within the range of the system) on one end of the
rope or web (Example: Maximum Tension = 100 Lbs.,
hang a 50 Lb. weight) (See Figure 8).
