SPEED CONTROLLER

ICS-600 & GS-600 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.Attach suitable connectors (optional) on the motor wires on the speed controller.

Otherwise, solder the  motor wires directly to the motor.  Be sure that the orange  silicone wire is positive (+) and the blue silicone wire is negative (-).connectors come with the regular wires, the red wire is positive (+) and the black wire is negative (-).

2.Attach quality connectors on the silicone wires that will match to the connectors from the battery pack.  The pink silicone wire is positive (+) and the green silicone wire is negative (-).

3.Connect the speed controller signal wires to the receiver throttle channel.

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

5.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.

6.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 4 to activate the speed controller.

7.LED DISPLAY   All off    =  Not activate / Auto-cut

Green on  =  Ready / Brake (for GS version)

Red  on  =  Full throttle

Red flash  =  Reset

8.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.

9.For bettery efficiency and maximum performance we would recommend to install the heat sink (supplied).

   Cut the shrink tubing and attach the head sink on the name plate(ICS-400, 600) or power MOS FET(ICS-300、480).
