4.0 Startup
Before applying power, make sure that all wiring is terminated correctly.
NOTE: Applying power with devices hooked up incorrectly may cause damage.
Turn the AC Breaker switch to the ON position. Verify that the main touch-screen LCD comes up displaying
gas readings on the display. You should also verify that the Controller module is being polled by observing a
sequence of blinking LED’s on the backside of the remote display’s control module. Check to make sure these
display readings are identical to those at the Model 1600/6400 Controller.
