KBIC DC Motor Speed Control Adjustments

On my KBIC speed controller model KBLC-240DS I want to adjust the trim pot where the P1, P2, P3 terminals are. Next to these terminals is an adjustment screw marked +12V Adjustments. The controller is plugged into 120VAC

What is the voltage in the P1,P2 P3 terminals? (I know I can use my meter but I don’t know if the volts are AC or DC)

The P1/2/3 terminals are for the 5k speed pot, Do you have the installation manuals for the drive?
I can send them over.
