∆ : It is needed to have a continuous signal to activate. When "Digital Pulse" is se-
lected, it only works in the pulse rise time.
"Digital Permanent" is a continuous signal mode, which means that actuator will oper-
ate when a continuous signal is present.

It is needs to set “NO” (Normal Open) or “NC”(Normal Close) (refer to section
8.8.3) as well.
"Digital Pulse" is the trigger mode, which means that actuator will operate when a
pulse signal is present.

A signal will be trigged when the pulse rise edge is received.

Once any stop signals are received such as manual override enable, torque over-
load and so on, a pulse signal needs to be present again to continue the opera-
tion.

While the “ESD”, “Disable Close” or “Disable Open” is actived, the “Run
Close”, “Stop” and “Run Open” functions will be invalid.
