QK-2000 Curtis Motor Control Diagnostic Lights

The QK2000 series machines with a 1237-3402 Curtis motor control box have a fault
light as standard equipment. At the left side of the Curtis motor controller's label is a
3/16-inch window with the word "STATUS" written over it. This window contains a light,
which can be used to help diagnose a problem if a machine fails to operate. The
flashing will be in the form of a code with "dots" and "spaces" to identify the fault. The
" " shown below is a short flash of the fault light, the "--" is a space. The fault code will
be repeated until the fault is corrected or the machine is shut down. These fault codes
are common for the 1227 controller on the QK1000/PP1000 , 1237 controller on the
PP3000, and 1235 controller on the PP3100 and PP3150.
