REMOTE SIGNALING CONNECTIONS (OPTION)
The Protector 3 includes the feature of providing dry relay contacts for remote signaling capabilities.
Signals available for remote annunciation are:
"INPUT FAILURE" - N/O contact that closes upon loss of input power.
"LOW BATTERY" - N/O contact that closes when the unit is on battery operation and the batteries
approach inadmissible discharge status.
"BYPASS ON" - N/O contact that closes when the unit transfers the load to static by-pass.
"SUMMARY ALARM" - N/O contact that closes when the unit has any one of the following alarm
conditions. internal failure, system overheat, battery undervoltage.
3.4.1 Dry relay contacts for remote signaling are provided via connector (P2) on Control Board (A2), located on
the inside of the right door of the enclosure. See illustration 1-2 for location of Control PCB.
3.4.2 Dry relay contacts have the following maximum ratings:
125 volts (AC or DC) maximum
1.25 amperes maximum
30 watts / 50 VA maximum
It is important that contact ratings are observed to prevent damage to the relays and the Control Board.
3.4.3 Determine which signals will be used. Connect wires (customer-supplied) to the connector.
3.4.4 See illustration 1-2 for location of dry C contacts terminal.
This concludes the installation procedure. Please proceed to Section 4 - Start-Up.
