Operation
P831 Output Mode
This parameter determines the output mode of the mA output, from the
following.
Option
Description
0= Default (Default)
mA output follows P800 (Display Source)
1 = Flow
mA output according to flow reading
2 = Velocity
mA output according to velocity reading
Setpoint
By default, the mA Output will represent the 0% (0 or 4mA dependant on
(
P830
)
Output Range
) and
100%
of the operational
span
(
20mA
), but you
may wish to have the output represent a section of the operational span. For
example, the application has an operational span of 6 m/s but
output
is to
represent
0m/s
(
0
or
4mA
dependant on
(
P830
)
Output Range
) to a
level
of
5 m/s
(
20mA)
. If so P834 (Low Setpoint) should be set to 0.00 m/s and
P835 (High Setpoint) should be set to 5 m/s.
P834 Output Low Level
This parameter sets the measurement value at which the low mA output will
occur
(
0
or
4mA
dependant on
(
P830
)
Output Range
)
Default = 0 l/s
P835 Output High Level
This parameter sets the measurement value at which the high mA output will
occur
(
20mA
).
Default = 6000 l/s
Limits
P836 Output Low Limit
This parameter sets the lowest level that the mA output will drop to, the
default is 0mA, but you can override this if the device you connect to cannot
for example accept less than 2mA, yet you want to use the 0-20mA range.
Default = 0.00mA
P837 Output High Limit
This parameter sets the highest level that the mA output will rise to, the
default is 20 mA, but you can override this if the device you connect to
cannot for example accept more than 18 mA, yet you want to use the 0-20
mA range.
Default = 20.00mA
