Then tryAdd a manual abort pushbutton.Change the timer preset to 30 seconds.
What is in this drawing
Read the decisions behind it.
01
Use of timers (TON) to control valve open durations.
02
Seal-in circuit to maintain sequence enable.
03
Cascading timer done bits to trigger subsequent steps.
When sequential operation of actuators is needed with defined on-times and manual start/stop control.
