UDC 3300 Controller Product Manual

4/00

The UDC 3300 performs background tests to verify data and memory
integrity. If there is a malfunction, an error message will be displayed. In
the case of more than one simultaneous malfunction, only the one with the
highest priority will appear on the lower display.

A list of error messages is contained in Table 5-5. If any of these error
messages occur, refer to Section 9 - Troubleshooting for information to
correct the failure.

Unable to write to nonvolatile memory.

Two consecutive failures of input 1 integration.

Two consecutive failures of input 2 integration.

Two consecutive failures of input 3 integration.

Slidewire input failure. Position Proportional Control
automatically switched to Three Position Step Control.

Configuration Errors for Loop 1—Low limit greater than high
limit for PV, SP, Reset, or Output.

Configuration Errors for Loop 2—Low limit greater than high
limit for PV, SP, Reset, or Output, or Loop 2 output has not
been selected.

Input Combination Errors—Percent Carbon falls outside of
“sooting boundary.”

Input 1 Out-of-Range

Out-of-range criteria:

Linear range: ± 10 % out-of-range
Characterized range: ± 1 % out-of-range

Input 2 Out-of-Range—Same as Input 1.

Input 3 Out-of-Range—Same as Input 1.

PV Out-of-Range
PV = (PV source x PV source ratio) + PV source bias

Failsafe Loop 1—Check inputs or configuration.

Failsafe Loop 2—Check inputs or configuration.

Remote Variable Out-of-Range
RV = (RV source x RV source ratio) + RV source bias

RH Excessive Temperature Depression—Calculated % RH is
less than 0 %.

Segment Error—SP Program starting segment number is less
than ending segment number.

Not calibrated. Perform Position Proportional calibration.
