No-flow 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 such as an
alarm or shutdown.
Offset User-defined value to correct for known variance in the raw data.
Panel Ready In states, the first logical step in startup.
Permissive A process condition (digital input or analog setpoint) that must be met in order for the
sequence to proceed to the next state.
RTD A device for measuring temperature consisting of a device that changes resistance
according to temperature.
Signal An electrical quantity of voltage or current that is used to represent or signify some
other physical quantity such as the state of a switch (ON/OFF) or the status of a
device (SHUTDOWN/OK).
Span The difference between the full scale output and the offset as raw data.
Start Delay A time delay function to prevent premature start up.
State Predefined step of multiple logical steps (or states) needed to successfully start and
operate a compressor.
Thermocouple 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.
Type J uses Red (-) and White (+) insulation.
Type K uses Red (-) and Yellow (+) insulation.
