9.6.6 Display which corresponds to 4mA
output:
4 . 000
The Rate Totaliser display which corresponds to a
4.000mA output current is defined by this function.
Using the
&
or
*
push button select
4.000
in the
4/20mA output sub-menu and press
(
which will
reveal the existing rate or total display with one digit
flashing. The required display can be entered using
the
&
or
*
push button to adjust the flashing digit
and the
(
button to transfer control to the next digit.
When set as required press
)
to enter the value and
return to the
4 . 000
prompt in the 4/20mA output sub-
menu.
9.6.7 Display which corresponds to 20mA
output:
20 . 000
The Rate Totaliser display which corresponds to a
20.000mA output current is defined by this function.
Using the
&
or
*
push button select
20 . 000
in the
4/20mA output sub-menu and press
(
which will
reveal the existing rate or total display with one digit
flashing. The required display can be entered using
the
&
or
*
push button to adjust the flashing digit
and the
(
button to transfer control to the next digit.
When set as required press
)
to enter the value and
return to the
20 . 000
prompt in the 4/20mA output sub-
menu.
Notes:
1. If the calibration of the rate or total display
defined as the source for the 4/20mA output is
changed, the 4/20mA output will automatically
be set to give a constant 3.5mA output
irrespective of the display.
The 4/20mA
output should always be reconfigured
following reconfiguration of the source display.
2. If the Rate Totaliser and the 4/20mA current
sink output are powered from separate
supplies, the 4/20mA output current will
continue to flow when the Rate Totaliser
supply fails or is turned off. Powering both
from a common supply eliminates this effect.
