Delta DTM Series - DTM Control Mode Configuration

Chapter 5: Control Functions and Operating Instructions
DTM temperature controller operating manual
5-5
B. Switching from manual control to PID control: If the output was 40% before switching from
manual control to PID control, the program will take 40% as an initial value in PID
calculations after switching to PID, and will generate a new control output
 Notes: If power to the device is turned off while under manual control status, the original output
percent value will be retained after restarting power
5.1.2 Control Function Settings
PID:
A. Automatic control mode: Configured value setting of 0, 0:PID 1:ON-OFF 2:programmable
PID
B. OUTx control action: Configured value can be set as 0: Heating, 1: Cooling, 2: Disabled
C. Output control cycle: Setting range: 1~600, units: 0.1 sec
D. Run/stop: Configured value can be set as 0: Stop, 1: Run
E. Auto-tuning: Configured value can be set as 0: Stop, 1: Run
Note: It is necessary to make sure that the input and output channels are properly
connected to the corresponding equipment and measurement and control parameters have
been set before performing self-tuning
F. Proportional band (P), Integration time (I), Derivative time (D): PID parameter settings
 Notes:
1. If in dual output or cooling output, the cooling side proportional band (P), cooling side integration
time (I), and cooling side derivative time (D) must be set
2. These parameters can also be set using auto-tuning
G. % OUTx power (Automatic): Read the output operating quantity from each PID control
cycle
ON_OFF:
A. Automatic control mode: Configured value setting of 1
B. OUTx control hysteresis: Setting range: 0~9999, units: 0.1°C
C. Deadband: Setting range: -999~9999, units: 0.1°C
 Notes: The needed parameters can be written ahead of time, and the system will automatically
initiate this function when under dual output control, and use the preset parameters
Programmable PID:
A. Automatic control mode: Configured value setting of 2
B. Run/stop: Configured value can be set as 0: Stop, 1: Run, 2: End of program, 3: Pause
program
C. Start pattern: Setting range: 0~7
D. Start step: Setting range: 0~7
E. End step: Setting range: 0~7
F. Cycle count: Setting range: 0~99
G. Linked pattern: Setting range: 0~7
H. Start slope: Setting range: 0~3000, units: 0.1℃/min
I. Wait SV: Setting range: -999~999, units: 0.1℃
