YK-EP Style B Centrifugal Chiller
Description
Displays the cumulative amount of kilowatts used over time as the
VSD motor controller operates.
Displays the phase current measured to the motor.
Displays the Pre-Rotation Vane position as a value between 0 and
100%.
Description
Allows the user to specify the maximum allowed motor current (as
a percentage of FLA). When the motor current reaches this value,
the Pre-Rotation Vanes will not be permitted to open further. If the
motor current rises above this value, the Pre-Rotation Vanes will
close to reduce the current to this value.
Allows the user to specify the current limit value (as a percentage
of FLA) to which the chiller will be limited during the specified
pulldown limit time. This value will override the Motor Current
Limit value during this time period. This function is used to provide
energy savings following chiller start-up.
Allows the user to set a period of time for which the pulldown
demand limit will be in effect after the chiller starts.
Allows the user to reset the cumulative Kilowatt hours to zero (0).
(Harmonic Filter installed Only) Disable the filter logic from
activating, although the system will still communicate with the
device. Only available when chiller is stopped.
Description
Returns user to HOME Screen.
Moves to the subscreen which provides more information about the
Variable Speed Drive.
Moves to the subscreen allowing operator acknowledgement of the
compressor motor lubrication and viewing of the compressor motor
lubrication parameters. Only displayed if this option is installed.
Moves to a subscreen that provides information and setpoints
pertinent to the Motor Monitoring feature. Only displayed if this
option is installed.
