• Programming operation

Description TH-G/ I/ GU, TC-G/ GU series
Programmable pattern capacity 120
Pattern repeat time 999
Max. segments per a pattern 100
Available max. segments * 1200
Programmable process time per a segment 0 to 99 hr 59 min
* Even though the max. segments per a pattern are 100, available total segments are up to
1200 not 12000, so you need to arrange the number of segment and patterns properly.
