Operation
Reset/Test: Functionality of this control is dependant upon Automatic Disconnect Switch status.
Primary Status
•The primary Automatic Disconnect Switch is supplying power to the cable system. The Local Power LED will be illuminated. The Reset/Test button will do nothing.
•When the primary Automatic Disconnect Switch is not supplying power to the cable system the Remote Power LED will be illuminated. The Automatic Disconnect Switch will perform a test to measure the output voltage from the local FRP.
Secondary Status
•The secondary Automatic Disconnect Switch is supplying power to the cable system. The Local Power LED will be illuminated. The secondary Automatic Disconnect Switch will momentarily disconnect the local power from the cable system allowing the primary system to supply power. If the primary system begins to supply power, the secondary system will remain disconnected. If the primary system fails to supply power, the secondary system will immediately begin supplying power to the cable system.
•When the secondary Automatic Disconnect Switch is not supplying power to the cable system the Remote Power LED will be illuminated. The Automatic Disconnect Switch will perform a test to measure the output voltage from the local FRP.
Local 63 V Fault: Green LED indicates:
•The FRP/FLM output is outside the specified range during a test.
•The output failed while the Automatic Disconnect Switch was supplying power.
Primary/Secondary Select: This control is used to establish the Automatic Disconnect Switch as the primary or secondary power source for the cable system.
Primary: Green LED indicates that the Automatic Disconnect Switch is the primary power source.
Secondary: Green LED indicates that the Automatic Disconnect Switch is the secondary power source.
220 V Normal: Green LED indicates that 220 V input is present and within specified limits.
Cable Modem
The cable modem functions only when power is supplied by the Automatic Disconnect Switch to an FRP. If the FRP fails the cable modem will continue to function.
