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

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.

a percentage of Full Load Amps) to which the chiller
