ICS-100 & GS-100 SPEED CONTROLLER

GWS μ-CON SPEED CONTROLLERS

(2KHZ HIGH FREQUENCY RATE)

The GWS 'Li' speed controller especially designed for the lithium-iron or lithium-polymer battery (2S&3S).These controllers have automatic cutoff with auto detection for the 2 or 3 cells lithium battery. This circuit provides the correct cutoff voltage for the number of cells to avoid overdischarged,then leaving the remaining capacity for a safe landing.

(OPERATION AND PRECAUTIONS)

1.Connect the speed controller to the receiver throttle channel and the motor as per the wiring diagram.

2.First turn on your transmitter, then connect the battery pack.

3.Move the throttle stick to the lowest position and wait for a second, then push the stick upward to start the motor running.  If you don't keep the stick at the lowest position for a second,or the input battery voltage is too low(below 6V), the speed controller will not activate for your safety.

4.If the motor would not start to run, adjust the throttle trim downward.  If the speed controller still does not activate, disconnect the battery pack first and turn your transmitter off, then switch the reversing switch on your transmitter. Repeat the same procedure from 2 to activate the speed controller.

5.Cut off - The motor cutoff will occur when the input battery voltage drops below 5.4 volts (2S) or 8.1 volts(3S) for more than one half second, and also occur if the signal from the transmitter is lost, or if the radio noise becomes excessive.Once motor cutoff has occurred, moving the throttle to the braking position (full off for two seconds) will rearm the controller. This will allow restart of the motor at low throttle after cutoff has occurred.

WARNING : Repeated restarting of the motor may drain the battery to the point where the radio receiver will stop operating, resulting in a loss of control of the model.
