Troubleshooting T-CON Devices

Symptoms	Check
Two more devices seem to both be called device 1 after power up	Most likely one or more of the actuators was sending out data during renumbering. Simply center the knob (so the actuator stops moving or sending out data by itself), and re-initialize.
The controller recognizes less devices than actually daisy chained to the controller	The controller can accept a maximum of 3 daisy-chained devices. Connecting only 3 independent devices with no more than 3 independent axis. Otherwise, make sure the knobs on the actuators are all centered, and try resetting or re-initializing the devices.
Turning the rotary knob on the controller does not do anything, and the yellow LED on the actuator is dimly lit	Make sure that the knob on the actuator itself is centered so that it is not causing the actuator to move independently of instructions from the controller.
The controller appears to freeze on any screen and does not respond to commands.	The knob on the actuator may not be centered. Try centering the knob and try again. If the controller did freeze, simply remove and reconnect power to the setup after centering the knob on the actuator.
The display position moves erratically when I turn the rotary knob on the controller.	The knob on the actuator may not be centered. Try centering the knob and try again.
When switching screen from any menu back to the control screen while an actuator knob is turned, the control screen is blank or prints garbage.	If the actuator is in the middle of sending data when the controller requests it’s position it is possible to see this problem. Stop the offending device (center the actuator’s knob), select the messed up display and turn the rotary knob on the controller. This sends a fresh command to the device and retrieves the proper position.
The actuator is currently at a position X (250), and the step size is set at Y (1000). Why can’t I make the actuator go to zero by turning the rotary knob?	Turning the rotary knob sends a “Move Relative -1000” command to the actuator. 250 – 1000 = negative, which is out of range. The actuator ignores the command. Try moving the actuator with a smaller step size like Y = 50.
The actuator is currently at a position X (282624). I can’t seem to make it go any higher.	The actuator’s internal position counter is at or near its maximum range and cannot go any higher. This is the intentional default on power-up to prevent over-extension of the actuator. Home the actuator.
The controller will freeze on the hourglass symbol or freeze on a different screen.	This is because the controller sent a command to the actuator and is waiting for a reply. It is possible the device was removed, or miscommunicated. Reset the entire setup removing and reinserting the power plug.
