Safety By Pass Ki By pass this is a called K 00

while we map test and join sensors , people may use custom safety ki cards to suit their sensors
with out effecting GMS or Vic Matrix so we make a jumper

For this Cable style do we know part number or name of this type of connector or wire what is this called this type of wired insulation?

i attached 1 style all other suggestions welcomed

RATED 20 Kv  Name RP-SMA Cables & Adapters

Shielded high voltage insulated 20 kv wire

Stanley A Meyer DB37 k11 digital control means

gerber updated  to fit matrix back card

z ip gerber had a connection connect connected file i have added just a final gerber file called k11 which is correct here

Working on the main board,

Have a question,  i am looking at the db 9 connector out to the vic card

it has 4 pins 

Vee is marker on the interconnect drawing as going through db 9 connect and cable to vic

i am trying to find iff vee connect to  k3 and where exactly ?  one drawing show it but not clearly to hard trace
i know there is  A GATE FROM K3 to db8 and vic

any comment on this part welcomed

DAN

Generator Jet  Boiler Burner auto-start circuit description.

This design is for electric start generators which are supplied with remote controls.

(Note: It could also be used with electric start generators WITHOUT remote control BUT would need additional, rather complex circuitry.)

The idea is simple:
When the preset gas pressure is reached, the generator (engine) starts automatically.

Since all the electronic engine management control facilities in this design are already in place, this optional circuit which performs the auto-start function is very simple indeed!

Operating conditions are as follows:

After powering up the entire system, gas (HYDROXY) pressure rises.
When it reaches the pre-set limit, the pressure regulator circuit generates a control pulse.
The VERY FIRST pulse will SET the LATCH.
Its output goes HIGH and remains HIGH. 
(Until power is turned OFF.  At power-up, everything is RE-SET.)

Now, the LATCH ignores ALL further control pulses.
As its output is DC coupled to the ‘Clock’ input of the ONE-SHOT, a SINGLE pulse with a set time constant is generated.

For the duration of the pulse, a MOSFET (which drives a relay) is turned ON.
The relay contacts are wired across the remote control’s ON-button.
(Pulse duration depends on the time required by the remote control to start the engine.)

The circuit is based on a 4013 dual D-type F/F (Flip-Flop).
The first section is a LATCH and the second is used as a ONE-SHOT pulse generator which drives a MOSFET & relay.

It works as follows:

At power-on, LATCH IC1A is RESET by C2 (0.1u) & R3 (1M) and the ONE-SHOT (IC1B) is RESET by C3 (220n) & R5 (8M2).

When power is applied to the electrolyzer, gas pressure starts to build up.
As it reaches the pre-set pressure level for the first time, a positive control pulse is generated by the pressure regulator circuit.
(The design provides both positive and negative going control pulses.)

The very first control pulse (applied to pin 6) SETs the LATCH IC1A.

(Once the LATCH is SET, all subsequent control pulses are ignored.)

The output (pin 1) of the LATCH (IC1A) is DC coupled to the ‘Clock’ input (pin 11) of ONE-SHOT IC1B.
Before the first clock pulse arrives at its clock input, its Q output (pin 13) is LOW.
As resistor R5 (8M2) is connected between its Q output and RESET, its RESET input (pin10) is also LOW.
Since its D (Data) input (pin 9) is connected to the + supply rail, its output goes HIGH during the positive going transition of the pulse to its clock input (pin 11).

The output of ONE-SHOT (IC1B) is now HIGH while its RESET input (pin 10) is still LOW, current starts to flow from the HIGH output, through R5 (8M2), to the RESET input.

When the voltage reaches the RESET threshold, the ONE-SHOT RESETS (its output snaps LOW) and its pulse is terminated.

The entire cycle just described is a strictly ONCE ONLY event!

Only when the generator is stopped and re-started can the above cycle be repeated.

The circuit can be turned OFF or ON in order to select MANUAL or AUTO-START.

Here is a simple method of testing this ‘autostart’ circuit for correct operation:

Apply power to it.  (12V)
The indicator LED must remain OFF.
Attach a wire to CN3/TP2 and briefly touch the other end of this wire to TP1 (+12V).
The LED will turn ON for about 1-2 seconds.  (then OFF and remain OFF)
Repeatedly touch the wire to TP1.
The LED should NOT come on, no matter how many times the wire is connected to TP1.

Now remove the power (12V) from the module, wait 10-15 seconds (a deliberate delay built in to this circuit) and repeat the process described above. 
Note:  if you don’t wait long enough (10-15 seconds), it will NOT work again.

The effect of this delay is that once the generator is stopped (which means no power to operate the electronics), the ‘autostart’ function will not operate for the next 10-15 seconds, even if power is restored immediately!

So the Matrix is up to series 10 now starting to look sweet

Dan  Gerber attached

there are fine tuning and adjustments for this rather analogue version

goal is to make it as a training device easy to read and study it
