IC 40 function
4 .10 Manual mode
For simplified commissioning, the actuator can be
operated “by hand” via the BCSoft® software. Manual
mode is activated via BCSoft®.
A distinction is made between two types of Manual-
mode: Direct position preset and Simulate inputs. The
related set-ting options are enabled after the required
Manual mode is selected.
The exterior, applied input signals have no effect on the
control element in both Manual operating modes.
Instead, the device responds to the presets from the
software.
Fast blinking of the blue LED indicates that the actuator is
in Manual mode.
Only one Manual mode may be activated at any one
time. If the Manual mode is to be changed, the existing
Manual mode must first be deactivated before the other
Manual mode can be activated.
4.10.1 Direct position preset
This Manual mode serves to determine the operating
positions for the process, such as the low-fire rate (low)
position, the ignition (middle position) and the high-fire
rate (high) position.
For this purpose, the actuator can be moved to any
position, regardless of the input signal. The position can
be entered or changed directly in BCSoft®. The resolution
is defined in ranges fine/medium/coarse, whereby “fine”
allows any step of the step motor (< 0.05%).After transfer
of the values from BCSoft® to the actuator, the actuator
responds accordingly to the new presets. The new
position is always approached at maximum speed in this
case.
The operating position determined can be assigned in
BCSoft® to a position, for example ignition position.
4.10.2 Simulate inputs
When this Manual mode is activated, the external inputs
are deactivated. Instead, the signals of the two digital
inputs can be pre-set “manually”. If the actuator has a 4
– 20 mA analogue input (option), this can also be
simulated.
Switching the inputs allows the behaviour of the actuator
to be tested. This allows the set running times to be
checked and optimized in BCSoft®. 60
