PARALLEL EEPROM ALARM
This signal becomes active when the system detects an error on the non-volatile RAM (Parallel EEPROM) where
event list and counters are stored.
SERIAL EEPROM ALARM
This signal becomes active when the system detects an error on the non-volatile RAM (Serial EEPROM), where
a duplicate of the unit settings are stored (duplicated).
DEFAULT GENERAL SETTINGS
If the General Settings have never been changed, the system has the factory default General Settings. This signal
shows this situation.
TABLE 1 DEFAULT SETTINGS
If the settings on Table 1 have never been changed, the system has the factory default Table 1 settings. This
signal shows this situation.
TABLE 2 DEFAULT SETTINGS
If the settings on Table 2 have never been changed, the system has the factory default Table 2 settings. This
signal shows this situation.
TABLE 3 DEFAULT SETTINGS
If the settings on Table 3 have never been changed, the system has the factory default Table 3 settings. This
signal shows this situation.
EXTERNAL TRIGGER
This signal turns ON and OFF as the External Trigger Digital Input is energized and de-energized.
TABLE 1 ACTIVE
TABLE 2 ACTIVE
TABLE 3 ACTIVE
These three signals report which table is active each time. If the digital inputs intended to change tables are de-
energized, then these signals would reflect the value set on setting ACTIVE TABLE.
COMMUNICATIONS TRIGGER
This signal becomes active when a trigger command is issued, either from the local HMI (keyboard and display on
the front of the relay) or from the GE_LOCAL communications software.
