Tension Controller TC818

8.2  Troubleshooting

  Appearance of failure

  Solution

 The controller does not work 
 after powered on

 

Incorrect calculation of radius

 

No output

 Measurement fails, display 
 “A/D error”

 Measurement fails, display 
 “sigl error”

 

The power supply is 110-264 VAC.

 

1. Check the connection of power supply.

 

2. Replace new fuse(4A).

 

1.Set proper values for the radius calc. related parameters.

 

2.Use proximity switch or encoder with NPN signal

 

3.Check connection or replace new proximity switch or 

encoder

 

1.Press the 

OUTPUT ON/OFF button

 to turn on

 

2.Switch

 

off, switch on after 30 seconds

 

3.Connect the drive unit properly

power 

 

In need of repair

 1.Select the right range for Signal[26

]

 

2.Check the connections and signal, replace new 

sensor.

  Possible malfunction

 

Power fails or fuse fused.

 

1.The setting of radius calc. related parameter is incorrect.

 

2.Wrong proximity switch/encoder.

 

3.proxmity switch/encoder damaged or incorrect connection.

 

1. Output has been turned off

 

2. Output short-circuit protection

 

3. Incorrect connection of Reel A and Reel B

  A/D IC damaged

 

1. Signal range and sensor do not match

 

2. Sensor fails or incorrect connection.

 

The keys and digital knob

  do not work

 

The controller does not start 

  after MC1 is on

 

Can't switch to automatic 

  mode

  Tension too high or too low 
  after restarting

  Setting tension(SV) changes after 
  switching from manual mode to 
  automatic mode

 

Check the 

Lock

 indicator, if the indicator

keypad is locked. Press 

LOCK

 key to unlock.

 1. Disable the Sync. Mode[42
switch must be mounted on the main reel while 
enabled and set right value for Start Freq.[03].

 

2. Set right value for Action Mode[41].

] function. The proximity 

 

1. Check sensor, connections, parameters and 

      recalibrate until getting the correct measurement
  2. Keypad locked, press 

LOCK

 key to unlock.

 1. Keep the MC1 off before stopping
 2. keep the MC4 on

  This is normal, it makes the smooth transition.

  Keypad has been locked

  1. Sync. Mode[42] is enabled.

 

2. Bad value for Action Mode[41].

 

  The automatic/manual switching is disabled 
  when error appears

 

1.The measured tension is incorrect

 

2.Keypad locked

  1. MC1 is on when system stop
  2. MC4 is off, output memory is disabled

  While switching the controller from manual  
  mode to automatic mode, the measured 
  tension before switching will be used as the 
  setting tension for automatic control

 Measurement fails, display
  “over range”

 

1.Recalibrate

 

2.Check connections and signal, replace new sensor.

 

3.Set Sensor

[

24] according to real condition.

 

1. Invalid calibration

 

2. Sensor fails or incorrect connection

 

3. Bad value for Sensor[24].

  Not stable in manual and 
  automatic mode

 Stable in manual mode but
 not stable in automatic mode

 1. Reinstall
 2. Use the appropriate drive unit
 3. Use the appropriate sensor and recalibrate

 

 1. Use the appropriate sensor and recalibrate
 2. Use the appropriate drive unit
 3. Alter the value of these three parameters

  1. Tension sensing roller out of roundness, 
      bearing damaged, roller bended.

 

2. Bad clutch/brake or driver

 

3. Signal fails or incorrect calibration

 1. Bad type of tension sensor.
 2. Bad type of clutch, brake or driver.
 3. Bad value for Prop. Band[05], Inte. Time[06] 
and Dead Band[07]
