CHAPTER 4: CONTROL MODES IN DTC
4.1 ON/OFF
There are four control modes in DTC: ON/OFF, MANUAL, PID and PID PROG. Due to that DTC has
no display panel, the settings and monitoring of parameters have to rely on communication.
Therefore, you have to check the following 2 items to ensure normal communication.
1. Make sure RS-485 hardware communication cable in DTC has been connected to the computer.
2. Make sure the communication parameters in DTC are consistent with those in the computer.
Next, open DTCOM Software and switch to ON/OFF control mode.
