Chapter 5: Control Functions and Operating Instructions
DTM temperature controller operating manual
implementation step is set as Soak as a default. The temperature is first set as the target
temperature X, and the temperature is then held at X. The time required for this whole
process is T
E. Linked pattern: This refers to the linking to another pattern number after implementation
of the first pattern. A setting of 8 ends the program, but the program will maintain the final
configured value; a setting of 9 ends all programs, and turns off output
F. Cycle count: This parameter controls the additional rounds of implementation in the
pattern; if set as 1, the pattern will be implemented 2 times
G. End step: This parameter controls the number of valid steps in the pattern. If set as 4, the
pattern will be implemented until step 4, and any remaining steps will not be implemented,
in which case the system will directly proceed to the next linked pattern or action
H. Wait time, Wait SV: After the programmed temperature curve setting has been completed,
the Wait time and Wait SV can be set. When the current measured temperature (PV) is not
within a steps ( Step SV ± wait SV), the wait time will be treated as a countdown, and the
system will wait until the current measured temperature is within the steps ( Step SV ± wait
SV) before proceeding to the next step. If, after counting down to 0, the current measured
temperature is still not within the steps (Step SV ± wait SV), and alarm will be generated.
I. Execution:
When the Control state is Run, the program will start to execute from the Start pattern
and Start step, and will be executed sequentially.
When the Control state is Stop, the program stops and the control output is disabled
When the Control state is at Program ends, the temperature is controlled at the set value
before stopping. If it is re-executed, the program will be executed from the set Start
pattern and Start step.
When the Control state is Program pause, the temperature is controlled at the set value
before stopping. If it is re-executed, the program will continue to execute the steps before
the stop and the remaining time.
J. Read SV value in Programmable control:
When the content of the function address Hx14F is set to 0, the value read to the address
Hx270~x277 is the set value of this step; when the content of the Hx14F function address
is set to 1, the value of the address Hx270~x277 is the dynamic setting value of this step
according to time change.
Here x is the internal station number of the DTM host or measurement expansion module.
