Special instructions: general, no physics triggers

[gladky]

• If trigger shifter activates physics triggers and no physics triggers are passing (CPMController web page > Rates and deadtimes),check in the CPMController page whether they are enabled (under "input sources"). If not, TCDS needs to be reconfigured.

This is a very rare case. It is unlikely that reconfiguring TCDS will fix it, as the enabling/disabling input sources need a new TCDS configuration nowadays. I guess this stems from times where the input sources could be disabled by the hardware hacker. Therefore, I would remove this instruction.
