DESCRIPTION
The BA627E-SS is a rugged general-purpose SetPoint Station housed in a
stainless steel panel mounting enclosure which enables the current flowing in
a 4/20mA loop to be manually adjusted from within a process area. The BA627E-
SS is loop-powered and includes a five-digit display that may be calibrated to
show the 4/20mA current in linear engineering units.
This abbreviated instruction sheet is intended to assist with installation and
commissioning, a comprehensive instruction manual describing system design and
calibration is available from the BEKA sales office or may be downloaded from
the BEKA website
www.beka.co.uk/manuals.html.
INSTALLATION
The BA627E-SS has IP66 front of panel protection but should be shielded from continuous direct sunlight and severe weather conditions. The rear of the instrument has IP20 protection.
Connect M4 earth stud to panel enclosure in which Set Point Station is mounted
Support panel wiring to prevent vibration damage

EMC
For specified immunity, all wiring should be in screened twisted pairs, with
the screens earthed at one point.
Scale card
The SetPoint Station’s units of measurement are shown on a printed scale card
visible through a window at the right-hand side of the display. The scale card
is mounted on a flexible strip that is inserted into a slot at the rear of
the instrument as shown below.
Fig 4 Inserting flexible strip carrying scale card into the slot at the rear of Set Point Station.
Thus the scale card can easily be changed without removing the Set Point
Station from the panel or opening the instrument enclosure.
New Set Point Stations are supplied with a printed scale card showing the
requested units of measurement, if this information is not supplied when the
Set Point Station is ordered a blank card will be fitted.
A pack of self-adhesive scale cards printed with common units of measurement
is available as an accessory from BEKA associates. Custom printed scale cards
can also be supplied.
To change a scale card, unclip the protruding end of the flexible strip by
gently pushing it upwards and pulling it out of the enclosure. Peel the
existing scale card from the flexible strip and replace it with a newly
printed card, which should be aligned as shown below. Do not fit a new scale
card on top of an existing card.

OPERATION
The BA627E-SS Set Point Station is controlled and configured via four front panel pushbuttons 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 pushbuttons have the following functions:
Output current slowly decreases. After five seconds the rate of change
accelerates so that large changes may be made quickly. Push button first
followed by a button to decrease the output current.
Output current slowly increases. After five seconds the rate of change
accelerates so that large changes may be made quickly. . Push button is first
followed by the button to increase the output current.
- Optional dependent on configuration
Pushing this button for 5 seconds enables the Set Point Station output to be entered digit by digit in engineering units using the push button to adjust the flashing digit and the button to move control to the next digit. When set as required pressing the button will enter the new setpoint value and the output current will change.
While this button is pushed the BA627E-SS Set Point Station will display one of three alternatives depending upon how the instrument has been configured. Output current in mA; output current as a % of span or provide access to the pre-set outputs.
While this button is pushed the Set Point Station will display the numerical value the Set Point Station has been calibrated to display with a 4mA or 20mA output.
+ Access to configuration menu via optional security code.
CONFIGURATION
The BA627E-SS Set Point Station is supplied calibrated as requested when
ordered, if not specified default configuration will be supplied but can
easily be changed on-site.
Fig 6 shows the location of each function within the configuration menu with a
brief summary of the function. Please refer to the full instruction manual for
detailed configuration information.
Access to the configuration menu is obtained by pressing the and buttons
simultaneously. If the Set Point Station security code is set to the default
0000 the first parameter rE5n will be displayed. If the Set Point Station
configuration menu is protected by a non-default security code, CodE will be
displayed and the non-default code must be entered to obtain access to the
menu.
