Chapter 4. Configuration
RX3i CEP Configuration Validation
Some configuration validation is performed by the RX3i CEP Carrier when the configuration is delivered to it.
The following table indicates the configuration validations performed for the indicated modules. If the RX3i CEP
Carrier detects an invalid configuration for a given module, the module transitions to module default operation
and point faults are energized on the assigned I/O.
If a module listed below receives an invalid configuration, it rejects the configuration, energizes point faults and
blinks its OK LED. The module does not transition to an operational state, as indicated by the OK LED being On-
Solid, until a valid configuration is stored.

Rules
Number
1. Pulse test diagnostic reporting and fault reporting must be disabled when pulse testing
is disabled.
2. Open wire and short circuit diagnostic reporting must be disabled when the channel is
IC695MDL664
configured for dual-state input type.
3. Short circuit diagnostic reporting must be disabled when the channel is configured for
tri-state input type.
1. Pulse test diagnostic reporting must be disabled when pulse testing is disabled.
IC695MDL765 2. Auto Pulse Normal State and Auto Pulse Default State must not be equal to each other if
pulse testing is enabled.
1. The High Scale Value Engineering Units cannot be equal to the Low Scale Value
Engineering Units.
2. The High Scale Value A/D Units must be greater than the Low Scale Value A/D Units.
3. The Alarm Limits must be in order, with the High High Alarm greater than or equal to the
High Alarm, which is greater than the Low Alarm, which is greater than or equal to the
Low Low Alarm.
IC695ALG112
4. The Alarm Limits must be within the configured Engineering Units plus User Offset
IC695ALG312
range, for example if the High and Low Engineering Unit Scale values are 10,000 and -
IC695ALG616
10,000 and User Offset is 1000, the alarm limit range is +11,000 to -9,000.
IC695ALG626
5. The Alarm Deadbands must be set such that the Alarm can be cleared. For example, if
the Engineering Units Scale Range is -5 to 5 and the High Alarm is 4, the High Deadband
must be less than 9 or else it is not possible to reach a value that is low enough to clear
the High Alarm. Note that the User Offset modifies the range of Alarms and Alarm
Deadbands. The User Offset is added to the High and Low Engineering Unit Scale Values
to set the alarm range limits.
1. through 5: Same as IC695ALG112
IC695ALG600
6. The Lead Resistance Compensation must be set to disabled for RTD 2-wire operation.
