Name and Location Description
Faulted/Ready/Running/High
Pressure/Alarm/Overtemp Bypass Indicator. Indicate the various state of the HPU
Faulted - red: Indicates when an interlock has occurred and the
HPU has been shut down.
Ready - green: Indicates the interlocks are cleared and the HPU is
ready to start.
Running - green: Indicates the HPU is running in low pressure.
High Pressure - green: Indicates at least one pump motor is
running in high pressure.
Alarm - yellow: Indicates a filter is dirty and needs attention. Also
could indicate a module fault or sequence override.
Overtemp Bypass - yellow: Indicates an over temperature
interlock has occurred and the HPU has been put into a bypass
mode to circulate hydraulic fluid through the heat exchanger until
the hydraulic fluid level reaches an acceptable temperature,
Enable Module - blue: Indicates that no modules are enabled. It
alerts the user to enable one or more modules before the HPU can
be started.
Enable Module #1 through #6
Module #1 through #6 Enabled
Pushbutton/Indicator. Used to enable and disable the available
pump modules. Pressing the button alternates between the two
states.
Enable Module #N - gray: Indicates the pump module is disabled
and can not be started.
Module #N Enabled - green frame: Indicates the pump module is
enabled and can be started.
Module #N Enabled - flashing green button: Indicates the pump
module is running in low pressure.
Module #N Enabled - solid green: Indicates the pump module is
running in high pressure.
Fault- red: lights when the module has an overload or a contactor
sequence fault
Run/Stop/Bypass Pushbutton/Indicator. Pushbutton used to start and stop the HPU.
Run - gray. black letters: In this state, press to start the HPU
Stop - gray, red letters: In this state, press to stop the HPU
Bypass - blue, white letters: This can only be done at the HPU
HMI. In this state, press to start the HPU in bypass mode. The
Faulted state will turn to Overtemp Bypass. Bypass mode only
occurs during an overtemperature condition and allows the HPU
to run in low pressure to cool the hydraulic fluid. For five minuets
per start, the system automatically resets to Ready if the system is
running in bypass and the overterperature condition clears.
