FIGURE 13 - ELECTRO-MECHANICAL STARTER SCREEN

Overview
This screen displays all information pertaining to an
Electro-Mechanical Starter.
Display Only
Motor Run (LED)
Illuminates when the compressor motor is being com-
manded 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 to 20mA, 4 to 20mA, 0 to 10VDC or 2
to 10VDC input in Analog Remote mode, PWM signal
in Digital Remote mode, MicroGateway interface in
ISN mode, or a locally programmed value.
Pulldown Demand Time Left
Displays the time remaining in the programmed
pulldown period if the value is nonzero.
Motor Temperature Switch (Open/Closed)
Displays the present position of the Motor Temperature
Switch. The normal position is closed. It is open when
there is a high temperature condition.
42
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 mo-
tor current reaches this value, the slide valve will not
be permitted to load further. If the motor current rises
above this value, the slide valve will unload 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 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.
Pulldown Demand Time
Access Level Required: OPERATOR
Allows the user to set a period of time for which the
Pulldown Demand Limit will be in effect after the
chiller starts.
