Drive System/'s
-DC DriveThe Curtis 1244 controller provides
diagnostic information to assist in the troubleshooting of drive system problems. The diagnostic information can be obtained by
observing the appropriate display on the handheld programmer or the fault codes
issued by the Status LED.
The LED is built into the controller and is visible through a window in the label on top of the controller. The Status LED Displays fault codes when there is a problem with the controller or the inputs to the controller. During the normal operation, with no faults present, the Status LED flashes steadily on and off. If the controller detects a fault, a 2-digit fault identification code is flashed continuously until the fault is corrected. For example, code “3,2” appears as the following illustrated flash sequence.
The complete list of sequences and meanings are given in the following table.
The following table gives the troubleshooting scenarios for the controller faults and should be referenced for suggestions covering the wide range of faults.
