There are 4 configuration lines that are available to configure the relays.
These are
1) Start up delay. This line is low for a time after the power is applied to the protection board, then it goes high.
2) Trip. This is a latching output that latches high whenever the DC is detected on pins 3/4 of P5 and P6.
3) Off. This goes high when the amplifier is in off mode.
4) Standby. This bit goes high when the amplifier is in either standby or off mode.

The inputs that you select are put into an 4-input NOR gate controling the MOSFET. This means that whenever a selected input bit goes high the corresponding relay will have no current through it.

There are 4 configurable low power outputs that are controlled by a 2n7002 mosfet. there are also 2 high power configurable outputs that are controlled by a IRF610 MOSFET. There is a 3rd High power configuable output that turns off during switch off and a trip event to control a main power relay.

these configurations are controlled by wires across the sets of holes on either side of the PCB. I will upload a picture of which connects to which shortly.

Regards.

Also note for LED polarity, Red connects to R46 Blue to R47

Heinz1, I am certain I have the right value, and even if you do have 0.1uF caps there the circuit performance should not degrade, and it certainly should function correctly (these are all decoupling capacitors) in fact any value over 0.047uF should work there.

It should be, however to be sure could you please post a picture of the part here. If it is a TI part in a TSSOP14 it should be. I think that is just the marking code for them.

Edit, I Checked my order history and the part I ordered was the CD74HC4002PW. please still post the image.

As for build order, I recommend that you build the Power supply first, followed by the amplifier, followed by the rest of the circuit.

I recommend that you do not solder in the LED until you are ready to place the board into the front panel so as to get the correct height.

I have been asked again via PM for the F5X PCBs.

As mentioned before a number of times, we have an agreement with the forum that they have exclusive rights to the PCBs.
Under that agreement, we may only supply the PCBs as part of a complete project (Batch 1 & 2, already closed).
As long as the forum has not given up its exclusive rights, you should contact them (Variac or Jason) for the availability of the boards.
I am not a member of the forum organisers, so I cannot, and will not, speak for them.

In any case, the Gerber files will not be made public.
I owe it to the person who spent a few hundred hours on it.
He does not agree to giving them away and seeing them later on Ebay with uncontrolled quality.

If the forum does not want to make them available anymore, for whatever reasons, then we will.
Assuming of course that we have an open statement from the forum.


Thank you for your interest,
Patrick

Here is as promised a connection diagram for the Protection PCB configuration switches.
To have the relay terminals OC when a control signal is asserted put a wire across the pins in the on column. Put a wire in the foo column everywhere else.

OFF is asserted when the amplifier is in off mode
SBY is asserted when the amplifier is in standby mode
TRP is asserted after a fault has occurred.
SUD is asserted while the protection board is turning on.
Regards.

Edit: almost forgot to attach the file
