MOD “A” SOLID STATE STARTER SCREEN
OVERVIEW
This screen displays all information pertaining to the
Mod “A” Solid State 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 Solid State Starter this
is the data returned by the Starter Logic 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 Remote mode, PWM signal in Digital
Remote mode, MicroGateway interface in ISN mode or
a lo cal ly pro grammed value in local mode.
Pulldown Demand Time Left
Displays the time remaining in the pro grammed pull-
down period.
Scale/Model
Display information about the Liquid Cooled-Solid
State Starter Rating and the maximum allowed Full
Load Amps.
Voltage - Phase A, B, C
Display the 3-phase input line voltage values being read
from the Solid State Starter.
Current - Phase A, B, C
Display the 3-phase motor current values being read
from the Solid State Starter.
PROGRAMMABLE
Local Motor Current Limit
Access Level Required: OP ER A TOR
Allows the user to specify the maximum al lowed 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: OP ER A TOR
Allows the user to specify the current limit val ue (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 sav ings
following chiller start-up.
