OVERVIEW
 
This screen displays all information pertaining to the 
Mod “A” Solid State Starter. 

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.

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. 

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.
