    8 Operation of Tension Control System 8.1 Run/Stop The run/stop operation of TC808 tension controller is controlled by MC1 and MCC. Connect a switch across the terminal MC1 and MCC, the switch is called Run/Stop switch of the tension system.
  • Page 13 Before starting dot start operation, let the system stop(turn the Run/Stop switch off) and the controller outputs PON to generate the preparatory tension. When the dot start switch is turned on, TC808 outputs PDOT made the system start running. The controller will maintain the output PDOT while the dot start switch is ON.
  • Page 14 AUTOK TENSION CONTROLLER TC808 8.5 Reel exchange In the two-reel operation, the reel exchange is controlled by the ‘reel exchange’ switch(MC2-MCC). This function is applicable when material on reel is over or full. When the switch is turned on, reel A is active.

    When use one tension sensor, make sure to short-circuit the unused tension signal terminals. 9.1 Jumpers setup TC808 accepts various tension sensor inputs: 1. Using micro-displacment based tension sensor(signal: 200mV, power supply: 5V) Please short jumpers JP7, JP8 and JP11, jump J8 to GND to get 5V output.

    R0) and reel pulses/r N2 must be set properly. The TC808 counts the pulses generated by the proximity switch mounted on material reel, according to the total pulses N and the initial reel radius, calculate the current reel radius according to the following formula: (Winding: +,unwinding: -) R=R0±T*N/n...
  • Page 18 40 N*M, setting tension is 50 N, material reel radius is 300mm = 0.3m. the output X=50*0.3/40=37.5% As the above formula shows, TC808 adjusts the output according to reel radius, the output is proportional to the reel radius and setting tension.

  • Page 19: Taper Tension Control

    The greater the taper ratio t1, the greater the change of tension when reel radius increases. If t1=0, TC808 performs constant tension control. See the figure below.

  • Page 20: Diameter-Output Program Tension Control

    The diameter-output program tension control is a special application of diameter tension control. According to the presetting programs and the change of reel diameter, TC808 increase/decrease the output power to achieve tension control purpose. In this mode, parameter (( needn’t setting.
  • Page 21 If the current measured reel radius is greater than R1, TC808 outputs L1(the highest output). if the current measured reel radius is smaller than the minimum setting radius, TC808 outputs power which associates with the minimum radius.
