YK-EP Style B Centrifugal Chiller
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.
Description
Returns user to HOME Screen.
Moves to the subscreen allowing operator acknowledgement of the
compressor motor lubrication and viewing of the compressor motor
lubrication parameters.
