SECTION 4 - OPERATING PROCEDURES
INTRODUCTION
This section explains the modes of operation, front panel indi-
cators and start-up procedures for the Quick Response
Controller (IMQRC01).
MODES OF OPERATION
The QRC has three modes of operation: EXECUTE, CONFIG-
URE and ERROR mode. The mode can be changed using an
operator interface. Operator interfaces include the configura-
tion and tuning module (CTM), configuration and tuning termi-
nal (CTT), operator interface station (OIS), management
command system (MCS) or engineering work station (EWS).
Descriptions of the three modes follow.
Configure Mode
The configure mode is used to enter or update the control
strategy.
Execute Mode
The execute mode is the normal mode of operation. In this
mode, the module executes the control strategy, updates the
outputs and communicates over the module bus and slave
expander bus.
Error Mode
The error mode occurs when a hardware or software error is
detected (refer to the troubleshooting section for corrective
action).
STATUS LED
The QRC has a single status LED indicator. The status LED
has three states: green, flashing green and red. Green means
that the module is operating properly, executing control strate-
gies, updating outputs, etc. Flashing green means that the
module has been put in the configure mode or that a nonfatal
error situation exists. Red means that a fatal error has
occurred (again, refer to the troubleshooting section for correc-
tive action). Figure
shows the location of the status LED.
