ETS-Lindgren 2090 Controller - Manual (Page 37)

Model 2090 Multi-Device Controller
INITIALIZATION
STARTUP
The devices that will be controlled by the Model 2090 must
be properly connected to the controller before applying
power to the unit. If nothing is connected to the Model
2090 when power is applied the Device One and Device
Two displays will show dashes (-----).
The Model 2090 controller has a power-up diagnostic/self-
test to check for internal problems found during
initialization. During this period, the all display indicators
will flash on for several seconds to allow a visual
inspection, and then the firmware revision number will be
displayed in the left-hand (Device One) display window as
r X.XX where X.XX is the version number. If an internal
error is found during the startup sequence, an error message
"EXXX" will appear in the Device One display, where
XXX is the error code.
