START-UP PROCEDURES
The controller starts up automatically. The front panel LED
(solid green) verifies that the module is enabled and
communicating.
MODES OF OPERATION
The controller module has three modes of operation: execute,
configure and error.
Execute
The execute mode is the normal mode of operation for the con-
troller module. The status LED is solid green. The controller
reads the configuration, monitors and updates outputs, com-
putes the algorithms, and performs self-diagnostic routines.
The configuration cannot be changed but parameters such as
gains and time constants may be tuned, and block outputs can
be monitored.
Configure
The configure mode is used to enter new configuration data,
and delete or modify an existing configuration. The status LED
is blinking green. When this mode is entered, the analog out-
puts are held at their present value, the digital outputs are
de-energized, and the algorithms are not computed. Existing
parameters can be modified, and blocks can be deleted or
added, and tunable parameters can be adjusted with an opera-
tor interface device.
Error
If the MFT is not reset, an error exists. The following are some
examples of errors that will cause the MFT to time out and the
status LED to go red:
•
Reference out of acceptable tolerance.
•
Excessive analog output gain/offset.
•
Power failure/reset during EEPROM write operation.
•
Trip Block activated.
