CS-40 User's Manual
Ground Missing: Lit when the unit has detected a missing Service Ground. The
CS-40 will not close the contactor until a proper Service Ground has been
connected. The front panel Red PROTECTION light will be lit, and the Diagnostic
LED will be flashing at a faster rate.
Note: If a missing ground is discovered, power should be turned off before re-
connecting the ground. If ground is reconnected without turning off the power,
it will be necessary to wait 5 minutes for the
CS-40 to clear the Ground Missing error.
Table 2 below illustrates the information that can be obtained from the 4 LEDs on
the PC board.
