System Status LED and Alarm Relay
Possible system status LED indications:
Green LED - indicates normal operation. Alarm relay (see Table 10 above) is enabled,
indicating that Alarm is OFF – normal operation condition.
Yellow/Amber LED - indicates system is or has moved outside of the normal operation
Go/No-Go window as a result of external disturbance, system’s instability, etc. In this case,
the Alarm relay is disabled, indicating an Alarm condition.
Immediately after power up, the LED will turn red, then flash green for a 5 seconds. The
period, when the LED flashes green, is when new software can be downloaded using the
‘manual’ download option. Alarm relay is disabled, indicating Power-up condition.
The function of the LED and Alarm Relay can be customized for application-specific
requirements.
