Why is the BST Controller actuator not moving, and a warning symbol is displayed?
- M
  Michael BaxterSep 8, 2025
  If the BST Controller's actuator isn't moving and the display shows a warning symbol, it could be because the actuator has been activated for more than 50 seconds without interruption in the same direction, no web of material has been threaded, or no web tension exists. Activate the actuator in the opposite direction, check for broken parts within the actuator, thread the web of material, and check the web tension.

How to stop BST ekr 500 Controller actuator from trembling?
- E
  Edward TerrellAug 23, 2025
  If the actuator or guiding device of your BST Controller is trembling, it could be due to guiding system overdrive. Try optimizing the gain and carry out a material setup to resolve this.

What to do if BST ekr 500 Controller actuator does not move?
- J
  Jeffrey DanielAug 25, 2025
  If the BST Controller's actuator isn't moving, it could be due to a wrong actuator selection during start-up or the gain being set too low. Check the adjustment of DIL switch S4 in the controller and optimize the gain.

Why is my BST ekr 500 Controller not responding?
- S
  Stacey TaylorAug 27, 2025
  If the BST Controller isn't responding, a remote control might be connected, locking the control panel keys, or the device address of the controller/control panel might be set incorrectly. Deactivate the remote control and check the setting of the rotary switch S1 in the controller and the control panel.

Why does my BST ekr 500 actuator stay at the end position in automatic mode?
- M
  Maria ThompsonAug 27, 2025
  If, in automatic mode, the BST Controller's actuator moves to an end position and stays there, it might be because a material setup wasn't run after changing the material, or the actuator guiding direction is set up wrongly. Carry out a material setup and reverse the guiding direction of the actuator.

What does the warning symbol on my BST ekr 500 Controller mean?
- J
  josephfoxAug 29, 2025
  If the BST Controller's display shows a warning symbol, it could be that the controller supply voltage is outside the permissible range. Check the power supply and the mains wiring.

Why can't I shift the guiding setpoint on my BST Controller?
- N
  Nathan ValenciaSep 15, 2025
  If shifting the guiding setpoint via the arrow keys isn't possible and the message “EFE“ is displayed, the optional electronic remote precision adjustment EFE 1 is connected. Shift the guiding setpoint via the potentiometer on the electronic remote precision adjustment EFE 1.

What to do if BST Controller actuator with position feedback is not moving?
- R
  Robert EnglishSep 9, 2025
  If an actuator with position feedback (EMS 17, EMS 21, EMS 22) isn't guiding and the display shows a symbol, the actuator might have reached a software limit switch. Activate the actuator in the opposite direction to resolve this; the warning symbol will then be deleted automatically.

Why can't I activate the guiding mode on my BST ekr 500?
- P
  pmccormickSep 6, 2025
  If the guiding mode cannot be activated on your BST Controller, the corresponding sensor (sensor 1 or sensor 2) might not have been activated during start-up. Check the adjustment of DIL switch S5.
L

Why is my BST Controller edge sensor not working?
- R
  Robert ReidSep 4, 2025
  If a connected edge sensor isn't working with the BST Controller, it could be due to wrong settings during start-up or connecting two edge sensors with different signal polarity. Check the adjustment of DIL switch S5 and connect edge sensors with the same signal polarity.
