Operation
1
Once programmed, as described below, simply select the required servo
end position,
Set
or
Reset
using the operating switch. The servo will
move to the opposite programmed position, at the programmed rotation
speed.
2
If a bounce level is programmed for the current direction of travel then, as
soon as the programmed end position is reached the servo will reverse to
the bounce position at the same speed, reverse again and finally return to
the programmed end position at the same speed. This feature may be
used to realistically simulate bounce at end of travel of semaphore signal
arms or crossing gates and barriers. If you do not require bounce in either
direction of travel, program the relevant bounce level to zero bounce.
3
Once the servo has reached its programmed end position, and after a
further 1 second delay, the sense output will switch to the opposite state.
For
Set
, the output will switch from +5V to 0V and, for
Reset
, from 0V to
+5V. If this output is connected to the switch input of another servo
controlled switch, the second unit will start a
Set
or
Reset
operation on
completion of the same operation of the first unit.
4
Once the servo started has started moving towards either the
Set
or
Reset
positions it can not be stopped or reversed until it has completed its
programmed travel, as described in
3
and, optionally, a further
ten
seconds have elapsed [See below].
5
Note that, in
normal
operation, the LED indicator will be
off
, unless the
optional 10 second delay referred to in
4
is enabled. In this case, the LED
will illuminate continuously during this period. Otherwise, the LED is used
in programming mode only.
