CP2 level back under CDS PID control via temporary wiring
Cyrus has determined that the 24VDC originating in the LX VE rack and which energizes (enables) the instrument air to CP2's LLCV doesn't make it to the field wiring terminal strip in the rack -> As an interim measure, he "hot wired" 24VDC to the terminal strip.  As such, the PID output controlling CP2's liquid level is now effective -> He will consult with Richard as to replacement parts availability -> While in this "hot wired" state, the PID output to the LLCV will be "live" following reboot/restore scenarios and won't require manual enabling via MEDM screen (this can result on overfills)
