Relay Output Status Indicators
There are eight front panel indicators to display the relay sta-
tus. A lit red LED indicates an energized relay (active); a blank
LED indicates a non-energized relay (non-active).
START-UP PROCEDURES
The control module controls the start-up of the DSO module; it
is fully automatic. Function Code (FC) 83 in the control mod-
ule configuration enables the DSO. Specification 1 of FC 83 is
the module address. It must be the same as the address set
on the S1 address dipswitch of the DSO module. The front
panel LEDs (green solid, red off) verifies that the module is
enabled and communicating.
