Term Abbreviation Explanation
Number #
Hash represents a number. The description is the same for each item in the range. For
example, "Controller ID #" represents any of the possible controller IDs.
Oil pressure OP
Operate time
The time that the controller takes to measure, calculate, and change the controller
output. For each alarm, the reaction time is based on the minimum setting for the time
delay.
Out of service
A state that an alarm can be assigned to by an operator. Out of service alarms are
inactive alarms. Out of service alarms do not automatically return to service and require
operator action.
Parameter
A value, or set point, used to determine the controller's operation. Parameters include
nominal values, the configuration options for the configurable inputs and outputs, and
alarm settings.
Personal computer PC Used to run the PICUS software. For example, a laptop computer.
Phase L1 L1
The power line for one phase of a three-phase electrical system. Corresponds to R in
Germany, Red in the UK and Pacific, Red in New Zealand, Black in the USA, and U on
electrical machine terminals. The above colour codes are for guidance only. If uncertain
perform a phase measurement.
Phase L2 L2
The power line for one phase of a three-phase electrical system. Corresponds to S in
Germany, Yellow in the UK and Pacific, White in New Zealand, Red in the USA, and V
on electrical machine terminals. The above colour codes are for guidance only. If
uncertain perform a phase measurement.
Phase L3 L3
The power line for one phase of a three-phase electrical system. Corresponds to T in
Germany, Blue in the UK and Pacific, Blue in New Zealand, Blue in the USA, and W on
electrical machine terminals. The above colour codes are for guidance only. If uncertain
perform a phase measurement.
Phasor
A complex plane representation (that is, a magnitude and direction) of a sinusoidal
wave.
Power P The 3-phase active power, measured in kW.
Power factor PF The 3-phase power factor.
Power in Control Utility
