Model LXi-1400 is a combined automatic and
manual reduced voltage primary resistor fire pump controller, applied
where the capacity of the power source does not permit full voltage
starting of the motor. The controller is used with standard three (3) lead
squirrel cage motors. High capacity stainless steel resistors are
supplied, which reduce inrush current to approximately 50% of normal. An
adjustable timing relay is provided to control the time between reduced
voltage start and full voltage run. A manual "emergency run" operator
is supplied for emergency starting. When the operator is pushed "on"
the motor starts and runs at full voltage until the operator is pushed
"off".
