What is DEAD BAND ?
It’s an area/band where no action occurs due to the actuator input.
If the user inputs 12mA (50%), the actuator is supposed to stop exactly at 50% poaition. The actuator repeats from open to close in
order to stop at 50% position at this point.
This is what we call hunting, and if the hunting effect repeatedly occurs the motor can be damage. Therefor a dead band is set to have
some area in order to prevent this from happening.
It’s set to have 0.05mA per gradation. If it is at 1PH when shipped from the factory, it is set to have a 0.2mA dead band. If it is at 3PH,
on the other hand, it is set to have a 0.3mA dead band.
ex) If it is set to have a 0.2mA dead band, the actuator is positioned between 11.8mA to 12.2mA.
In case the actuator stops at the position of 12.1mA, the second least movement area will be at 12.3mA. At this position no action
occurs even when there is the input signal.

What is DELAY TIME ?
This is when there is an instant noise or disturbance from the outside affectin the input signal and therefore the ACTUATOR can’t
function. The delay time setting is to prevent this from happening. If the input signal does not change for more than the time set, the
ACTUATOR will kick in. The setting for the delay time is 0.5 seconds per gradation. When shipped from the factory the delay time is set
at 1 second.
