Overview:

Performing control while changing the set point temperature moment by moment is called running a program pattern (or simply running a program). Sterilization and pasteurization require maintaining specific temperatures for specific durations. 

Industries:
You can determine the other 5 DI terminal numbers from the model code. -*2* means no. 301–306. The others (except -*4*) are no. 501–506. -*4* means 303–304, 309–310, and 503–504 are added.
If you set JC=LOCAL, local operation status begins when the last segment of program operation ends. In this case, when zone PID (ZON=1,2,4) is selected, the PID group switches according to the selected zone. When segment PID (ZON=0) is selected, the ...
In the setup parameter ALM menu, set the AL1.S parameter to 4353 (AL01_L1). [Supplement] 4321(ALM1) is the alarm status of ON when an alarm occurs, and OFF when normal. 4353(AL01) is the alarm status determined by applying the settings for alarm ener...
With TSP, TIME, JC, and others displayed in the program pattern setting screen, you can switch between segments using the left and right arrow keys.
That's correct. Also set the wait zone (WT.UP1–5, WT.LO1–5) and wait time (WT.TM1–5) accordingly.
If you perform auto-tuning while programs are running, the program time pauses, and then resumes after auto-tuning is done. (Note that auto-tuning fluctuates the output and PV.)
If the segment setting type SEG.T (within setup parameter CTL) is TIME: segment time setting, you can temporarily change it after a hold. This is not reflected in the original program. If the segment setting type SEG.T is TM.RT: segment slope/time se...

If not using relay contact output for control, you can use it as a 4th alarm. This alarm would be the C contact type, therefore by connecting it to the N.C. (normal close) side you can use it as an alarm terminal. Note that when changing the basic sp...
You can change it if it is in a user profile (profile no. 0).To create a user profile, use the LL50A network profile tool.
