BA507E Loop Powered Indicator
DESCRIPTION
The BA507E, BA508E, BA527E and BA528E are panel mounting, general purpose
digital indicators that display the current flowing in a 4/20mA loop in
engineering units.
They are loop powered but only introduce a 1.2V drop.
The four models are electrically similar, but have different size displays and
enclosures.

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.
INSTALLATION
All the models have IP66 front of panel protection but should be shielded from
direct sunlight and severe weather conditions. The rear of each indicator has
IP20 protection.
The BA507E, BA508E, BA527E & BA528E are CE marked to show compliance with the
European EMC Directive 2004/108/EC

- Align foot and body of panel mounting clamp by turning screw anticlockwise
- Position gasket behind instrument bezel
- Insert instrument into the panel from the front Fig 2 Installation procedure
- Insert panel clamp into recess and gently pull it onto the dovetail. Engage screw & turn clockwise to tighten the clamp, fit the other clamp(s). Recommended tightening torque 22cNm (1.95lbf.in) Equivalent to finger tight plus one half turn. DO NOT OVERTIGHTEN
EMC
For specified immunity all wiring should be in screened twisted pairs, with
the screens earthed at one point
Scale card
The indicator’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.
Thus the scale card can easily be changed without removing the indicator from
the panel or opening the instrument enclosure.
New indicators are supplied with a printed scale card showing the requested
units of measurement, if this information is not supplied when the indicator
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 new printed
card, which should be aligned as shown below. Do not fit a new scale card on
top of an existing card. Fig 5 Fitting scale card to flexible strip
Align the self-adhesive printed scale card onto the flexible strip and insert
the strip into the indicator as shown above.
OPERATION
The indicators are controlled via four front panel push buttons. In the
display mode i.e. when the indicator is displaying a process variable, these
push buttons have the following functions:
P While this button is pushed the indicator will display the input current in
mA, or as a percentage of the instrument span depending upon how the indicator
has been conditioned. When the button is released the normal display in
engineering units will return. The function of this push button is modified
when optional alarms are fitted to the indicator.
▼ While this button is pushed the indicator will display the numerical value
and analogue bargraph the indicator has been calibrated to display with 4mA
input. When released the normal display in engineering units will return.
▲While this button is pushed the indicator will display the numerical value
and analogue bargraph the indicator has been calibrated to display with 20mA
input. When released the normal display in engineering units will return.
E No function in the display mode unless the tare function is being used.
P + ▼ Indicator displays firmware number followed by version.
P + ▲ When alarms are fitted provides direct access to the alarm
setpoints if the ‘ACSP’ access setpoints in display mode function has been
enabled.
P + E Provides access to the configuration menu via optional security
code.
- Only the BA527E & BA528E have a bargraph
CONFIGURATION
Indicators are supplied calibrated as requested when ordered, if not specified
default configuration will be supplied but can easily be changed on-site.
Fig 4 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 and for a description of the lineariser and
the optional dual alarms.
Access to the configuration menu is obtained by pressing the P and E buttons
simultaneously. If the indicator security code is set to the default ‘0000’
the first parameter ‘FunC’ will be displayed. If the indicator is protected by
a security code, ‘CodE’ will be displayed and the code must be entered to
obtain access to the menu.
