Status LED Flashing Patterns
After the controller is powered on, the Power LED will tun on, indicating that the controller is On. The Status LED
will be flashing at a 2 seconds interval. The flashing pattern provides operating or exception status information.
Additional status information may be obtained by monitoring the controller with the PC utility.
Self-Test and Reset Default Configuration
It is possible to verify that the controller is functioning by activating a self-test that will in turn ramp the motor(s)
up to full forward power and down to full reverse power. Then it toggles each digital output. To activate self-test,
turn off the controller, short RS232 Rx and Tx pins together (Pins 2 and 3 of I/O connector), and turn the controller
on again. The process will repeat until power is turned off and the RS232 is no longer shorted. Activating the self-
test also resets the controller settings to factory defaults.
Note: RS232 cannot be connected to PC as this will prevent the controller from entering the self-test mode.
