I am running two loops each on a separate variable output. Each is set up as a Track in the TIU. When I power up the TIU, both tracks in the DCS app show 22 volts. But the voltage to the tracks is zero. I have throttle the track voltage down in each track to zero and then back up again to get power to the physical tracks. Do I have something set wrong or is this the way the TIU is supposed to behave?
