YORK INTERNATIONAL
ELECTRO-MECHANICAL STARTER SCREEN
OVERVIEW
This screen displays all information pertaining to an
Electro-Mechanical Starter.
DISPLAY ONLY
Motor Run (LED)
Indicates whether the digital output from the controls
is commanding the motor to RUN.
Motor Current % Full Load Amps
Displays the motor current as a percentage of the Full
Load Amps (FLA) value. For the Electro-Mechanical
Starter this is the data returned by the CM-2 board.
Current Limit Setpoint
Displays the current limit value in use. This value could
come from a 0-20mA, 4-20mA, 0-10VDC or 2-10VDC
input in An a log Re mote mode, PWM signal in Digital
Re mote mode, MicroGateway in ter face in ISN mode
or a lo cal ly pro grammed value.
Pulldown Demand Time Left
Displays the time remaining in the programmed pull-
down period if the value is non-zero.
PROGRAMMABLE
Local Motor Current Limit
Access Level Required: OPERATOR
Allows the user to specify the maximum allowed mo-
tor current (as a percentage of FLA). When the motor
cur rent 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.
Pulldown Demand Limit
Access Level Required: OPERATOR
Allows the user to specify the current limit value (as a
percentage of FLA) to which the chiller will be limited
during the speciÞ ed 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.
Pulldown Demand Time
Access Level Required: OPERATOR
Allows the user to set a period of time for which the pull-
down demand limit will be in effect after the chiller starts.
