I/O CONFIGURATION MENU
This menu is used to configure the relay settings, 4–20 mA
output, and communication parameters of the Model
300/301. Refer to pages 13 and 14 for the complete menu
layout. The first part of this section shows how to configure
each type of relay (fault, alarm, and lead lag). The second
part shows how to configure the 4-20 mA and RS-485 out-
puts. The I/O Configuration Menu can be entered from the
RUN mode by pushing ENT and the pressing twice.
RELAY SETTINGS
The 300/301 transmitter can be provided with four relays,
two relays, or no relays. The relays can be configured to be
fault (diagnostic) relays, alarm relays (controlled by level, vol-
ume, or flow), or lead lag (pump control) relays.
Fault Relay Configuration
Relay #1 is the only relay that can be used as a fault relay to
indicate when the diagnostics of the 300/301 have deter-
mined that there is a fault condition. There are six fault con-
ditions that will change the state of relay #1 when a fault
occurs: echo loss, ringdown, transducer fail, no transducer,
bad transducer, and temperature fail. See the
Troubleshooting section for details on each of these fault
conditions.
