8.0 Glossary
A An na allo og g IIn np pu utt Terminals A18 to A29 are analog inputs on the C3-1 Centurion main I/O module. Accepts
voltage signals within the range of (0 to 5) VDC or (4 to 20) mA and are compared to con-
troller set points or events.
B Bo oo ott llo oa ad de err
Means by which the Centurion controller communicates with C3-3 Display and MConfigPro
to receive and transfer new or updated configurations and firmware; and ensure data and
configuration synchronization.
C Co on nttrro olllle err S Se ett p po oiin ntts s User defines normal operating range for the controller to optimize the equipment. Set
points can also define some other threshold, exception or event that may require action.
Multiple set points are often applied to a process and they may be manipulated as needed
to meet changing conditions.
D De ea ad d b ba an nd d The user set range at which input may fluctuate without the controller taking any action.
The range may be fixed or variable.
D Diig giitta all IIn np pu utt
Terminals 30 to 61 are the digital input channels. User selects whether digital input is nor-
mally open (N/O), or normally closed (N/C). Users may also associate these inputs with
transition times for indicating no-flow conditions on divider blocks.
E Ev ve en ntt Defines the action required by the controller in response to any number of parameters.
Event actions range from simple alarm message to emergency shutdown (ESD).
M Ma ag gn ne ettiic c P Piic ck k U Up p Terminals 64 to 65 are for magnetic pick up.
M Ma ax xiim mu um m Maximum of engineering applied scale to the Offset and Span.
M Miin niim mu um m
Minimum of engineering applied scale to the Offset and Span.
N No o--F Fllo ow w Designed to protect against compressor or engine failures, the controller monitors the cycle
time of lubrication system cycles and if that cycle time falls under a user assigned value, the
controller will activate a defined associated action.
O Offffs se ett
User defined value to correct for known variance in the raw data.
P Pa an ne ell R Re ea ad dy y In States, the first logical step in start up.
P Pe errm miis ss siiv ve e A process condition, (Digital Input or Analog Set point), that must be met in order for the
engine to start.
S Siig gn na all An electrical quantity of voltage or current that is used to represent or signify some other
physical quantity.
S Sp pa an n The difference between the full scale output and the offset as raw data.
S Stta arrtt D De ella ay y A time delay function to prevent premature start up.
S Stta atte e Predefined parameter of logical steps needed to successfully start and maintain an engine.
T Te errm miin na all E Em mu ulla atto orr
Allows a user to modify the firmware to allow upload or download of a record to either the C3-3
display or the controller. Always download a configuration after a firmware change.
T Th he errm mo oc co ou up plle e
A device for measuring temperature consisting of two dissimilar metals of high purity for an
accurate temperature/voltage relationship. User defines whether the calibration is J or K.
Terminals 1 to 17 are for thermocouple inputs.
