BATTERY OK: When on steadily this LED indicates that the external bat-

tery is fully charged. When blinking it indicates that the battery is low. When

off it indicates that the battery is either not connected or very low.

PHONE Status: This LED indicates if the SCADA 3000 is currently using

the phone line.

14. Input Terminal Strip: These terminals are for connecting input sensors and

transducers. The upper row is the positive input and the lower row is the

negative input. The inputs are differential for certain jumper configurations so

be sure to wire them in direct vertical pairs (eg. The positive input wire directly

above the negative input wire).

15. Input Configuration Jumpers: These jumpers are used to condition the

input for different types of sensors. Use needlenose pliers to move them to the

appropriate position. (See Chapter 5: Input Wiring)

16. Voice Port: This jack is for plugging in a telephone to listen to a status report

or record messages if the voice option is installed.

17. Phone Line: This is the jack for connecting to the telephone network.
18. Phone Extension: This jack is for connecting telephone extensions to the

same line as the SCADA 3000. This jack features Line Seizure so that if the

SCADA 3000 needs to make a call it will disconnect the extensions and seize

the line for its own use.

19. Expansion Bus Terminal Strip: This terminal strip is for connecting the

4-wire communications link to the I/O expansion modules.

20.

Bus Termination: This jumper selects whether the expansion bus is termi-

nated or not.

21. Spare Fuses: Spare fuses are provided for the main power, 24V supply, aux

supply and battery.
