Current Output Menu Options
11 4 mA Setpoint
Factory Set = 0
This option sets the distance (or level or space, depending on the selected
Operating Mode
(
Option
01
) at which the 4mA output will occur.
By default 4mA will represent
Empty
(0% of Span)
12 20 mA Setpoint
Factory Set = Span
This option sets the distance (or level or space), depending on the selected
Operating Mode
(
Option
01
) at which the 20mA output will occur.
By default 20mA will represent
Full
(100% of
Span)
Important Information
The
Span
is the maximum working distance from
Empty
(0%)
to
Full
(100%), and is automatically calculated as
Empty
Level
(Option 04)
minus Blanking Distance
(Option 05).
Except for when
Operating Mode
(Option 01) =
Distance
in
this case the
Span
is the
same
as the
Empty Level
(Option
04)
13 mA Fail-safe Value
Factory Set =3 (22mA)
If the SLM600 Series fails to receive a valid echo return from the target, then the mA output can be
used to indicate a fault condition (Loss of Echo). This option determines the mA output value which
will indicates such a condition.
Option
Description
1 = 3.8mA
Fault condition (LOE) indicated by 3.8mA
2 = Hold
The previous measured value outputs
3 = 22mA
Fault condition (LOE) indicated by 22mA
14 mA Fail-safe Time
Factory Set = 300 sec
In the event of a fail-safe condition occurring (LOE) the fail safe timer determines the time before
the mA output indicates a fault condition (LOE).
