Operation
CableGuard applies a current-limited, fixed DC voltage to the cable circuit during idle periods. A solid-state comparator circuit monitors measured leakage current to the ground. Two adjustable set points, factory preset to customer specifications, can be programmed to signal a pre-alarm, alarm, and lockout the equipment from operating if the low set point is exceeded. The manual reset feature enables a return to operational status only after the alarm condition has been corrected. CableGuard will not impair the normal operation of the equipment being monitored.
