Function

Lights when there is a failure in CH1 communication

Lights when there is a failure in CH2 communication

Lights when a Channel 1 ping-pong test (round-trip delay measurement) is successful.

Lights when a Channel 2 ping-pong test (round-trip delay measurement) is successful.

Lights when a communications failure is detected.

Lights when a problem is detected in a specific phase controller module.

Light when the CCS TRIP relay contacts are carrying dc trip currents of at least 0.2 ampere

(STD.).

These indicators are latched in non-volatile memory, and can only be reset by

pressing the RESET switch.

Indicates operating status, parameter values, and alarm codes. The display contains

16 alphanumeric LED readouts, arranged in two eight-character lines. The top line

displays either the mode or the selected operating parameters within each mode.

The bottom line displays additional information about the mode or parameter

appearing on the top line.

Lights green when protection is enabled; turns red when trip function outputs

are disabled.

Lights red when RFL 9300 backup is active.

Indicate direct transfer trip status:

TX:Lights when DTT command is sent to remote unit.

RX:Lights when DTT command is received from remote unit.

These indicators are latched in non-volatile memory, and can only be reset by pressing the

RESET switch.

Lights when the CH1 transmitter is functioning

Lights when the CH2 transmitter is functioning

Lights when the CH1 bit error rate (BER) is within limits.

Lights when the CH2 bit error rate (BER) is within limits.

Lights when a system problem not involving communications is detected.

Lights when fault detector for that phase produces an output.

Light when the DTT trip circuit carries dc currents of at least 0.1 ampere.

These indicators are latched in non-volatile memory, and can only be reset by

pressing the RESET switch.

Used to enter security codes, parameter numbers and select parameter values.

(See Figure 6-2 and Table 6-2 for more information on keypad functions.)

If the RFL 9300 is in the PROGRAM mode and the keypad is not used for four minutes,

the RFL 9300 will automatically return to STANDBY mode. If it is in the READ mode,

the time-out is extended to two hours.

Light to indicate the phase controller has issued a trip signal:

A: Phase A trip.

B: Phase B trip.

C: Phase C trip.

G: Ground (3I 0 ) trip.

These indicators are latched in non-volatile memory, and can only be reset by

pressing the RESET switch.

Used to manually reset alarms. When this switch is pressed, all indicators on the

display module (except PROTECTION and BACKUP) will light for three seconds to test

their function before they are reset. After the indicators on the RFL 93B DISPLAY

module go off, indicators 5, 6, 7 & 16 will light. If the RESET switch is pressed

while the RFL 9300 is in the READ or PROGRAM mode, the RFL 9300 will

return to the STANDBY mode.

Allows a user to connect a PC to access the RFL 9300. See paragraph 6.5 for more information.
