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 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.
Defines the maximum amps at which the motor can operate this
value is viewable when logged in at VIEW or OPERATOR level.
The maximum programmable value of this setpoint is equal to
Programmed Drive Current value received from the MVVSD.
Allows the user to reset the cumulative Kilowatt hours to zero.
