2.1

Controls - two handed

The BA627E-SS Set Point Station is controlled and
configured via four front panel push buttons located
below the display.

In the operating mode i.e. when

the Set Point Station is controlling the loop current
and the display is showing the output in engineering
units, these push buttons can have two alternative
sets of functions depending upon whether the Set
Point Station has been configured for two or single
handed operation.

Two handed operation is the default configuration
which minimises the possibility of accidental adjust-
ment of the output current by requiring that the

)

button be pressed at the same time as the

button to make an adjustment.

This configuration

also prevents the optional external encoder from ad-
justing the output current unless the

)

button is op-

erated.

)

Output current slowly decreases. After five
seconds the rate of change accelerates so
that large changes may be made quickly.

)

Output current slowly increases. After five
seconds the rate of change accelerates so
that large changes may be made quickly.

)

Continuously pushing this button for 5
seconds allows the Set Point Station output
to be entered in engineering units digit by
digit using the

push button to ad-

just the flashing digit and the

(

button to

move control to the next digit.

When set

as required, pressing the

)

button will

enter the new set point.

(

While

this

button

pushed

the

BA627E-SS Set Point Station will display
one of three alternatives depending upon
how the instrument has been configured:

Output current mA without bargraph

Output as a % of span

Pre-set outputs in engineering units

The display will flash. While continuing
to press the

(

button, operating the

& or *

button will show the identifica-

tion of the pre-set closest to the present
Set Point Station output, followed by the
pre-set value. Operating the

& or *

button will scroll through the five pre-
sets and an ‘Abort’ position. Releasing
both buttons will leave the selected pre-
set value or ‘Abort’ legend flashing for
ten seconds, during which time operat-
ing the

)

button will update the Set

Point Station output to the displayed
pre-set value. If the

)

button is not op-

erated during this period, the Set Point
Station output will not be changed and
the original engineering display will be
shown.

While this button is pushed the Set Point
Station will display the numerical value and
analogue bargraph the Set Point Station
has been calibrated to display with a 4mA

output. When released the normal display
in engineering units will return.

While this button is pushed the Set Point
Station will display the numerical value and
analogue bargraph the Set Point Station
has been calibrated to display with a
20mA

input. When released the normal

display in engineering units will return.

If the Set Point Station display has been

calibrated using the CAL function, calibra-
tion points may not be at 4 and 20mA.

2.2

Controls - single handed

The BA627E-SS Set Point Station is controlled and
configured via four front panel push buttons located
below the display.

In the operating mode i.e. when

For single handed operation only the

push

button has to be pressed to adjust the output current
as shown below. This configuration also allows the
optional external encoder to adjust the output current
without the

)

button being operated:

Output current slowly decreases. After five
seconds the rate of change accelerates so
that large changes may be made quickly.

Output current slowly increases. After five
seconds the rate of change accelerates so
that large changes may be made quickly.

)

Continuously pushing this button for 5
seconds allows the Set Point Station out-
put to be entered in engineering units digit
by digit using the

push button to

adjust the flashing digit and the

(

button

to move control to the next digit.
