5 System self-supervision
The EAFR-101C includes an extensive self-supervision feature .
Self-supervision includes both internal functions and external
connections . The self-supervision module monitors power supply,
hardware, and software malfunctions, and binary input connection
and sensor problems . Dipswitch settings are also supervised by
comparing the actual value with stored non-volatile memory data
(see Section 3 .3 .1: Auto configuration [System setup]) .
In a healthy condition, the POWER LED is on and the System Failure
(SF) relay is energized . If the self-supervision function detects a
faulty condition or the power supply fails, the self-supervision relay
is released and the ERROR LED is illuminated .
If a sensor failure occurs, the relay will go into ERROR mode . The
ERROR LED will illuminate, the SF relay will release, and the corre-
sponding faulty SENSOR CHANNEL LED will start blinking . In this
situation, the relay is still in the protection mode, but with the faulty
sensor channel blocked . If the error is resolved, the ERROR LED
will automatically clear the SF-status and failed SENSOR CHANNEL
LED will remain in blinking status . This means that the SF relay will
energize and the ERROR LED will turn off . If one or more of the
sensors are disconnected, the healthy sensors remain in use and
relay remains operational . The EAFR-101C will remain in error mode
until the disconnected sensors are repaired .
If a dipswitch setting is changed after the auto-configuration function
(see Section 3 .3 .1: Auto configuration [System setup]) has been
executed, the relay will go into SF alarm mode . The configured
(stored) setting is however still valid and the relay is still operational .
