[1] Before calibrating, ensure the connection of the sensor is correct and jumpers JP7, JP8, J8, L1 and L2
have been set corresponding to the tension sensor.

For LX series tension sensor, please short-circuit jumpers JP7 and JP8, jump J8 to +5V and set

In dancer control systems(using 2K Ohm potentiometer), please short-circuit jumpers L1, JP7 and JP8
and set
Signal[26]
to
±
300 mV.
[5] The output signal of the tension sensor can be tested using a multimeter, before testing, please switch the
multimeter to the
200mV position.The output signal should be about 0mV when there is no load applied to
the tension sensor.
While applied some force to the tension sensor, the readout of the multimeter will be changed: The bigger
force, the stronger signal, but it won’t exceed the max output range of the tension sensor, the output signal of
LX series tension sensor won’t exceed 200mV, for SUP/CTS/HTS series tension sensor, the upper limit is
20mV, if the measured signal exceeds the upper limit, the tension sensor may be damaged, please replace
new sensor and reinstall then re-calibrate.

For SUP/CTS/HTS series tension sensor, please open jumpers JP7 and JP8, jump J8 to +10V and set

Calibration Completed

In order to implement the closed loop tension control system, the tension controller must be calibrated after
installation, and only the proper calibrated controller can get the desirous measurement precision. The
controller uses two-points linear calibration method, the process is very easy.
4.1.3.1 Calibration notes
13
Purpose: To compensate for the sensing roller weight and for any of the other analog zero offset voltages.
Note: The zero calibration must be performed with the weight of the tension sense roller and without
material.
In dancer control systems, adjust the dancer roller to the lowest position.
