5V BEC = up to 400mA on Rx pins. Maximum continuous 100 Watts. ALWAYS MAKE SURE THE BATTERY IS FULLY CHARGED BEFORE USE..

REVERSER & INERTIA CONTROL
The setting of the reverser relay and the inertia period is controlled by a separate reverser channel with a
centre zero detent control. Small knob on RCS Tx handpieces using Channel # 3.
To correct for errors in transmitted pulse widths, the 1.50 ms stop PWM setting value can be user calibrated.
The inertia period quoted is the time to increase from zero to full motor voltage, and vice versa. It is
adjustable in units of 1 second, depending on the rotation of the reverser control.
With default settings, the Reverser Relay is de-energised in Forward. If required, this can be changed by
the user to be de-energised in Reverse.
REVERSER RELAY
The reverser relay will change state only when the required direction of operation is changed from Forward
to Reverse and vice-versa. It will not change state when the reverser control is set to Stop from either
direction of operation.
The relay state will only be changed when:
1: The actual motor voltage has reached zero, and has remained at zero for at least one second, and
2: The reverser control has been set to the opposite direction, and
3: The transmitter speed control has first been set to zero [if not already at zero], and
If the reverser control is set the opposite direction with a motor voltage greater than zero, an immediate
Emergency Stop will be executed [See below].
OPERATING MODE
The # OMEGA-10 has three user selectable operating modes:
1 Standard Linear 0% to 100% PWM Output for zero to maximum speed demand.
2 Shunt Control [1]. Non Linear 0% to 100% PWM Output for zero to maximum speed demand.
Decreased output at low settings of the Tx speed control [25% out at 50% in]
3 Shunt Control [2]. Linear 0% to 50% PWM Output for zero to maximum speed demand.
See Page # 1 for graph of operating mode characteristics.
The current operating mode is indicated by LED flash at PWM output = Stop [see above], unless an
emergency stop condition is present [see below].
TO CHANGE THE OPERATING MODE.
1. In normal operation, set Speed = zero, & wait until the LED indicates that zero speed has been achieved.
2 Press and hold push button switch for 2.5 seconds. The LED will flash rapidly.
3 When the LED changes to fully on, after 2.5 seconds, release SET-UP push button switch & the unit will
immediately change to the next mode. After Mode 3, it will revert to Mode 1. The LED flash sequence will
immediately change to the indicate the new mode.
Repeat Steps 1 to 3 to change the operating mode again.
Each time the operating mode is changed, the new settings are stored in non-volatile memory and will be
remembered until changed again.
POWER PROTECTOR
If you have turned on the handpiece with the regulator away from the off position, the OMEGA-10 will not
give you power until you have returned the regulator to off, then there is a one second delay.
If control is too abrupt or too sluggish, you can adjust the power curve on the OMEGA-10 as shown above.
EMERGENCY STOP.
During normal operation, the inertia control is operational for both increasing and decreasing motor voltages.
With high inertia settings, this can result in a significant period to bring the vehicle to rest, even if the
transmitter speed control is switched rapidly to zero speed.
For safety reasons, the OMEGA-10 incorporates an emergency stop feature to over-ride the inertia control
setting and immediately de-energise the motor.
To activate emergency stop from any speed setting, set the reverser control to the opposite direction.
The OMEGA-10 will immediately enter emergency stop mode, and de-energise the motor, indicated by the
LED flashing rapidly emergency Stop.
The emergency stop will be maintained until reset manually by the operator by setting the Speed control
back to zero speed, and the Reverser control to Stop. Normal operation will then resume automatically.
On initial power up of the OMEGA-10, an emergency stop will be set automatically, to ensure that the motor
is held at zero speed, irrespective of the initial transmitter speed setting until the transmitter speed control
has first been set to zero speed, and the reverser control to stop.
WIRING UP THE LOCO
The recommended wiring method is shown on Page # 3. The 100W OMEGA-10 requires a suitable fuse for
protection. For maximum protection use a 3 amp fast blow fuse for smaller locos. A 6 amp fast blow fuse
should be used for larger locos. If any erratic behaviour fit the supplied Balun core choke in motor leads.
The 3 x wire servo lead is plugged into the Rx Reverser position. Usually Ch # 3.
The single white wire is plugged into the Rx Throttle position. Usually Ch # 1.
JST In-Line connector cables are available separately. See the RCS website.

THE # OMEGA-10 SHOULD WORK STRAIGHT FROM THE BOX. IF IT DOES NOT,
PLEASE CALIBRATE THE SYSTEM AFTER A FACTORY RESET. See below.
The # OMEGA-10 can be user calibrated to accommodate transmitter, receiver, speed, reverser stop &
direction PWM settings that differ from the standard nominal values within the following limits.
Reverser Stop [Step 1]
·The reverser stop PWM value must lie within the range 1.45 ms to 1.55 ms
Speed [Steps 2 and 3]
·The total input PWM value range must lie within 0.70 to 2.30 ms.
·The input PWM value corresponding to max speed may be greater or less than the zero speed value.
·The zero and maximum speed PWM values must differ by at least 256 µs.
Reverser Direction [Step 4]
·The reverser direction calibration setting [Step 4] must match the zero or maximum speed setting.
TO PERFORM A CALIBRATION. ENSURE THE KNOBS ARE SET CORRECTLY.
A. After the Tx and Rx have been bound, turn them both OFF. Then turn the transmitter back ON.
B. Energise the # OMEGA-10. The LED will flash rapidly for 2.5 seconds.
During this period, press and release the SET-UP push button switch. If the SET-UP push button is NOT
pressed during this period, the unit will enter normal operation, on its conclusion.
C. When the Rx has bound to the transmitter, LED will go fully on, indicating ready for Calibration Step # 1.
CALIBRATION STEP # 1 - REVERSER NEUTRAL SETTING.
A. The LED will be fully energised [No Flash].
B. ENSURE the transmitter reverser control is in the centre detent NEUTRAL position.
C. Then press and release the SET-UP push button. Provided that the NEUTRAL setting is within the
constraints listed above, the new reverser NEUTRAL setting will be saved to non-volatile memory.
D. The # OMEGA-10 will now automatically proceed to Calibration Step # 2.
CALIBRATION STEP # 2 - ZERO SPEED SETTING.
A. The LED will flash slowly with a 1:1 On:Off ratio [Equal Flash].
B. ENSURE the transmitter speed control is set to the required Zero Speed position. Fully CCW.
C. Then press and release the SET-UP push button.
D. The # OMEGA-10 will now automatically proceed to Calibration Step # 3
CALIBRATION STEP # 3 - MAXIMUM SPEED SETTING.
A. The LED will flash with a 7:1 On:Off ratio [Long Flash].
B. TWIST THE transmitter speed control knob to the required Maximum Speed position. Fully CW.
C. Then press and release the SET-UP push button.
D. The # OMEGA-10 will now automatically proceed to Calibration Step # 4.
CALIBRATION STEP # 4 - REVERSER DIRECTION.
COMMENTS. You are recommended, where possible, to always use the Reverser De-energised (C. A.)
setting as this results in the minimum # OMEGA-10 power dissipation. If necessary, reverse the motor
rotation direction by reversing the connections to the motor terminals.
A. The LED will flash with a 1:7 On:Off ratio [Short Flash].
B. Only set the transmitter speed control if you wish to change the RELAY as follows:
C. A. FOR Reverser De-energised in Forward.
Leave the transmitter speed control set at the Maximum Speed position
D. B. FOR Reverser Energised in Forward:
OR: Set the transmitter speed control to the Zero Speed position.
E. Then finally press and release the SET-UP push button. To return to normal operation.
Provided that all three calibration steps [Steps 2, 3 & 4] have been completed, & that the settings made are
within the constraints above, the new calibration settings will be computed & saved in non-volatile memory.
The unit will then restart, as if power had just been applied, with all new calibration settings fully operational.
If an attempt has been made to set invalid calibration values, the previous calibration settings will not be
changed, and the calibration procedure will automatically revert to calibration Step 2.
There is no exit from the calibration procedure until correctly completed, except power off.
FACTORY RESET.
1. With the # OMEGA-10 de-energised, press and hold the SET-UP push button.
2. Then power up the unit, with the push button still pressed.
3. The LED will flash slowly for 10 seconds, and then go fully on.
4. Then release the push button. The unit will reload all factory default calibration values into non-
volatile memory, and then restart normally.
If the SET-UP push button is released before the end of ten seconds, the unit will restart with no change to the
previous settings.
5. you to Re-calibrate the settings after a factory reset,WE ADVISE
