,
Hi
Default Value:
Lo
Default Access Level
4
Function number
4C12
to
4C14
Allows selection of input edge or level for digital inputs 1, 2 and 3 (terminal marked “DIGITAL IN”).
Select
Lo
for the input to be triggered by a low level signal i.e. input will be triggered whilst the input is held low.
Select
Hi
for the input to be triggered by a high level signal i.e. input will be triggered whilst the input is held high.
Select
LoE
for the input to be triggered by a low going edge i.e. falling from a voltage towards zero.
Select
HiE
for the input to be triggered by a high going edge i.e. rising from a low voltage.
Select
NonE
to disable this input.
See “Electrical Installation” chapter for further information.

Digital inputs 1, 3 and 3 de-bounce timer

Range:

Default Value:
5
Default Access Level

Function number
4C1A
to
4C1C
Allows application of a de-bounce timer for digital inputs 1, 2 and 3 (terminal marked “DIGITAL IN”). A de-bounce
time of between 0 and 1000mS can be set for inputs 1, 2 and 3. When a de-bounce time is set the signal level before
the input trigger signal must have been at that level for the de-bounce time or longer. This is used to help prevent
false triggering. For example if the input is triggered by a high level or high going edge and the de-bounce time is
set to 100mS then the input would have to be at a low level for at least 100mS before the input is triggered, if not
then the input trigger will not be accepted. See “Electrical Installation” chapter for further information.

Default Value:
5U
Default Access Level
4
Function number
4C0F
Allows selection of the excitation voltage where available on the input board at terminal or terminals. 5V, 12V or
18VDC (25mA max.) is available as transmitter supply this function allow selection of 5V (
5 U
) or 12V (
12U
) or
18V (
18U
). Transmitter supply voltages are approximate. If a change is made the
P.Out
function must be exited
before the supply will change.
