I came up with another new feature today:
Now the LED comes on as previously, whenever the Remote is in the detector range;
but when the ignition is turned on, the 'Ready' LED goes off (and turns on again when system 'Killed' until the remote moves out of range and 'arms')
The new artwork has been completed and pleased to say all works as planned
Old Controller:
New controller:
If you look carefully at the new board, if you find the LED output terminal, it now comes via a transistor rather than directly off the 'ready' (disarmed) reference
The transistor is gated by the final output condition, which turns the transistor 'off' when the ignition is on.
I incorporated a few other subtle changes when I was doing the new lay-out anyway.
This is the block diagram of how the circuit works, with the addition of the LED control switch:
For the main output control, the output at Point 'C' is normally 'Off'; when turned 'on' & 'C' goes high, that turns on the power switch(es), whether that be Power Relays or PDM60.
The first gate is that Point 'A' gives a 'Ready' output when the system is 'disarmed' by the output from the base 2012T controller; this output 'A' feeds power to the Relay Driver Input.
Without this 'ready' condition, regardless of other input stimulus, the output cannot turn on.
Now with the point 'A' condition active, we need to turn on the Relay Drive Transistor;
That stimulus comes from a momentary input from the clutch switch, which turns on the Clutch Switch Driver and gives high output at Point 'B'
Point 'B' turns on the main relay driver transistor.
When the Kill/Run switch is set to 'Run', that not only completes the ignition circuit for the bike, it also feeds back into the Key-Less Controller;
this feedback maintains point 'B' as high, even when the clutch switch driver turns off (which it will when you release the lever);
So the system becomes latched, until the Kill/Run is opened, breaking the feedback loop, and the latch is broken.
There is a built-in time delay on the feedback loop so that for any spurious 'bounce' condition, it does not shut off the circuit for any minor excursion.
Turning the Kill/Run back to Run will not immediately turn on the Relay Drive, it must again be initiated by the Clutch Switch.
In summary, once system has been disarmed (ready) the ignition is simply turned on by pull of the clutch lever, or turned off by the Kill/Run Switch
Note that even though other system currents are not going directly through the Kill/Run switch, this output signal gates the power control for ALL the switched circuits.
For the new LED driver, the 'Ready' (disarmed) output goes via a transistor switch to the OEM Alarm Indicator LED;
when the Output drive (point 'C') is off, the transistor is on, and so the LED is on.
When point 'C' goes high however (turning on the Ignition circuit via PDM60 or Relay) that also turns the LED drive transistor Off.
So the LED condition is:
Armed - OFF
Disarmed + Ignition Off - ON
Disarmed + Ignition On - OFF
(Note that in the Ignition On state, it's
not that it is no longer disarmed, simply that the status LED has been 'blanked')
The bottom part of the circuit is the Turn Signal Drivers - these flow current to the OEM turn signals on generated pulse signals from the base 2102T controller.
These generate a single flash when the system is arming, or a double flash when it is disarming.
These are visible of course as you move towards or away from the bike with the remote in your pocket.
Here's video that demonstrates the Indicator Lamp behaviour as it disarms, then ignition is turned on
(compare to the video in post 108, on page 11, where you will see the status LED remains on even after Ignition comes on)
A reminder that the video is predominantly looking at the Test fixture - it's the Controller that is actually 'doing the work'
And also (although spelled out in the video commentary) the 'green' status LED on the box is in actuality the Red OEM Alarm Indicator on the Instrument Panel; and there is no 'Ignition On' LED on the actual system, doesn't need one of course because your Instrument Panel indicates that you are powered on.
