August 9, 2001 4 - 4 (973) 334-3100
Notes for Tables 4-1 and 4-2:
1. Bias control and ground delay settings will track each other from 50 ms to 750 ms. Above 750 ms, the ground delay varies in non-
proportional steps:
Bias Ground
800 ms 2 s
850 ms 5 s
900 ms 10 s
950 ms 15 s
1000 ms 30 s
2. When this parameter is enabled and the [ENT] key is pressed, the Display Controller requests that the PROGRAM mode security
code (.248) be entered. Once it is, all parameter values will be reset to the default values listed above. These are the values the pa-
rameters are set to before the RFL 9300 leaves the factory.
3. When this parameter is set to ENABLE, the audible beeper can be used to notify the operator if an alarm condition exists. During pro-
longed alarm conditions, the user may wish to disable the beeper until the condition is corrected. It is recommended that this parame-
ter remain enabled. Alarms may not be noticed if the display is in the READ or PROGRAM mode, or if the RFL 9300 is not being
manned and the user is depending on the beeper to indicate an alarm condition.
4. When this parameter is shown, the [8] and [0] keys can be used to increase or decrease the display intensity (or brightness). When
the setting is changed, the bottom line of the display will change to the new intensity, while the top line unit remains constant as a ref-
erence. When the [ENT] key is pressed, both lines assume the new intensity setting.
5. In dual-channel systems, either channel number may be displayed if COMM MODE (Parameter #48) is set to AUTO.
6. Settings for phase inverse time-overcurrent backup parameters:
