MODEL - STC858A Parameter Description The following table have been classified based on function parameters. Parameter Name Description Parameter NO. Adjusting range Factory default Function selection parameters: the basic parameters of the following parameters should be set according to the actual situation of the first.
Tension detector installation and wiring STC858A accept a variety of tension detector input signals, to make the appropriate jumper settings for different detectors: Micro displacement special tension detector, the input signal range is 300mV, 5V power supply (such as the LS series, and mitsubishi tension sensor compatible) Sw1 switch settings are as follows:...
This controller can choose one or two tension detectors to work which based on tension detector installation conditions Settings. [24] Display unit STC858A can choose two units showing tension measuring value: "kg (kg)" and "N (Newton)" [25] Signal range The controller can choose two signals, ± 30mV and ± 300mV which depending on the installation of the detector selecting corresponding signal range.
STC858A tension controller are adopted two linear calibration which calibration process is very simple. (1) Note [1] Before calibration, ensure that tension detector is wiring correctly, confirm the tension detector works properly, the tension signal is within the selected range.

MODEL - STC858A (3) Full-scale calibration Tension detector Hang known weight load W (kg) Note: the weight of the load should not be less than ½ span of the tension detector. Tension detector Thread a string through the roller centers (1) Hang known wight W(kg) from the detector roller, refer to above drawing.
MODEL - STC858A Adjustment operation When tension was measured correctly, then enter to the automatic and manual operation mode of controller for adjustment. firstly operate it with manual control mode, when manual operation works normally, coil achieves proper and stable tension, then switch it to automatic control mode.
4.2.3 When STC858A in automatic control mode, proportion, integral, static area parameter values influence the stability and control precision of system, such as tension control is unstable which need to adjust and set the appropriate proportion, integral and static area parameter values.
