Device Startup
7SR5 devices can be started in any 1 of 3 modes:
•
Auxiliary Power On = Device is switched on by applying the auxiliary supply voltage.
•
Expected = User initiated start e.g. after a change to the device user configuration or firmware upgrade.
•
Unexpected = Caused by operation of the device self monitoring functions.
During the start up cycle the device should run the following process during normal behavior.
•
The LCD backlight switches on, then off, and then returns to a backlit screen displaying the device type
and startup logo.
•
The LCD brightness can be adjusted by pressing the Enter (↵) and Cancel (Χ) pushbuttons together,
then pressing the ▶ pushbutton. Using the ▲ or ▼ keys will then increase or decrease the brightness.
•
The following messages are displayed on the bottom of the screen:

On the last display a progress bar is displayed to show the progress the sequence is running. On completion
the device validates and runs the firmware, and completes the start up sequence. The device does this by
displaying the default Home Screen, operating the healthy output contact and illuminating the Healthy
LED green.
NOTE
The LCD contrast can be adjusted by pressing the Enter and Cancel pushbuttons together and then using
the ▲ or ▼ keys to increase or decrease the contrast.
