2.5 PROGRAMMING
Throughout this manual push-buttons are shown
in italics e.g.
P
or
Up
push-button, and legends
displayed by the instrument are shown within
inverted commas e.g. 'SCALE-t' and 'COdE'.
2.5.1 Accessing programme functions
Access to the programme menu is obtained by
operating the
P
and
E
push-buttons
simultaneously. If the BA364D is not protected
by a security code the first parameter ‘Function’
will be displayed. If a security code other than
the default code 0000 has already been entered,
the instrument will display 'COdE'. Press
P
to
clear this prompt and enter the security code for
the instrument using the
Up
or
Down
push-button
to adjust each digit, and the
P
push-button to
move control to the next digit. If the correct code
has been entered pressing
E
will cause the first
parameter ‘Function’ 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.
Once within the main programme menu the
required parameter can be reached by scrolling
through the menu using the
Up
and
Down
push-
buttons as shown by the counter programme
structure shown in Fig 2.3.
This section summarises all the counter
programmable parameters excluding the optional
alarms, 4/20mA analogue output and the re-
transmitted pulse output. When read in
conjunction with Fig 2.3 it provides a quick aid for
programming the instrument. If more detail is
required, each section contains a reference to a
full description of the function.
Programming details for the optional alarms,
analogue 4/20mA output and the re-transmitted
pulse output are contained in sections 2.6, 2.7
and 2.8
SUMMARY
Display
Description of function
‘Function’

'InPut A'
Type of input
Conditions input A to work with
one of five types of transducer:
‘UOLtS’
Voltage pulse
‘COIL’
Magnetic pick-off
‘Pr.dEt’
NAMUR proximity
detector.
‘COntACt’ Switch contact
‘OP.COL’ Open collector
See section 2.5.3
'InPut b'
Type of input
As above but for input B
See section 2.5.3
‘Count’
Input count mode
Defines the arithmetic
relationship of the two pulse
inputs A and B:
‘A : b’
A plus B
‘A : -b’
A minus B
‘A Con b’ A pulse, direction
controlled by B
‘A rEL b’ Quadrature A and B
See section 2.5.4
‘Cnt. EdGE’ Counting edge
Defines the edge on which both
inputs count.
See section 2.5.5
'd.P.'
Position of decimal points
Defines the position of the
decimal points in both displays.
See section 2.5.6
