BEKA BA514G, Manual

Page: 11 / 33

5.0 CONFIGURATION & CALIBRATION
The BA514G Tachometer is configured and calibrated
via four front panel push buttons. All the
configuration functions are contained in an easy to
use intuitive menu that is shown diagrammatically in
Fig 6.
Each menu function is summarised in section 5.3 of
this manual and each summary includes a reference
to more detailed information.
For simplicity the pulse output is described separately
in section 5.20 and factory fitted optional alarms and
4/20mA output are described separately in section 8.
All new Tachometer are supplied calibrated as
requested at the time of ordering. If calibration is not
requested, the Tachometer will have factory default
configuration as shown in the following table, but can
easily be re-configured on-site.

5.1 Configuration structure
Fig 6 shows the BA514G calibration structure.
The pulse input is divided by
5CALE.5
to provide the
required Tachometer speed display in engineering
units. e.g. if a sensor monitoring a rotating shaft
generates 18 pulses per revolution, to produce a
display in revolutions
5CALE.5
should be set to 18.0.
The timebase
t-bA5E
is a multiplying factor that
determines whether the Tachometer displays speed
per second, per minute or per hour.
The Tachometer incorporates a run-time counter that
displays the time in hours that the speed of the
monitored machinery has been equal to or greater
than the clip-off value.

5.2 Accessing configuration functions
Throughout this manual push buttons are shown as
&
,
*
,
(
and
).
Legends displayed by the
instruments are shown in a seven segment font as
they appear on the Tachometers e.g.
inPut
and
uPdAtE
.
Access to the configuration menu is obtained by
operating the
(
and
)
push buttons
simultaneously. If the instrument is not protected by
a security code the first parameter
inPut
will be
displayed. If a security code other than the default
code
0000
has already been entered, the instrument
will display
CodE
. Press
(
to clear this prompt and
enter the security code for the instrument using the
&
or
*
push button to adjust the flashing digit,
and the
(
push button to transfer control to the
next digit. If the correct code has been entered
pressing
)
will cause the first parameter
inPut
to
be displayed. If an incorrect code is entered, or a
push button is not operated within ten seconds, the
instrument will automatically return to the display
mode.
All configuration functions and prompts are shown
on the upper eight digit display.
Once within the configuration menu the required
parameter can be selected by scrolling through the
menu using the
&
or
*
push buttons. The
configuration menu is shown diagrammatically in
Fig 7.
When returning to the display mode following
reconfiguration, the Tachometer will display
dAtA
followed by
5AVE
while the new information is stored
in permanent memory.
