Edit the go pulse value.
If the actuator is still, the controller provides an
nn.n
amplified output signal for the defined pulse time to
nn.n
achieve a rapid startup of the actuator.
NOTE: If overshoot occurs, reduce go pulse value.
Edit the output offset percentage of the actuator.
Output offset linearizes the action of the used I/P
nn.n
module and enables rapid control until reaching the
nn.n
set point. An output offset between 40% and 80% is
acceptable for most actuators.
Edit the noise band of A/D conversion.
ADC noise band can be used as an interference indi-
nn.nnn%
cator. If the noise is big, the measuring accuracy and
control reaction is affected. Normally an acceptable
ADC noise band value is between 0.03% and 0.05%.
Select the I/P MODULE setting.
This defines the triggering or safe position to the
built-in I/P module. The setting must be the same as
the existing I/P module in the TZID/AZH positioner.
Select YES if changes were made to the parameters.
Select YES to make the changes permanent.
