2.11 Switch Setting for EL Logic
The switch S1 is used to set the EL limit switch ’s type. The default setting
of EL switch type is “normal open” type limit switch (or "A" contact type).
The switch on is to use the “normal closed” type limit switch (or “B” contact
type). The default setting is set as normal open type.”
"
For safety reason, users must set a type which will make the end-limit
active when it is broken or dis-connected.
