5.5.3

Instrument function:  

FunCtion

The BA577E-SS may be configured as a Timer or as
a   Clock.     This   section   of   the   instruction   manual
describes the Timer, for details of Clock configuration
see section 8.

To   reveal   the   existing   function   of   the   instrument
select  

FunCtion

  from   the   configuration   menu   and

press 

(

.   If 

ELAP5E

 is displayed, the instrument is

already configured as a Timer therefore press 

)

 to

return to the  

FunCtion

  prompt  in the  configuration

menu.     If  

CloC

  is   displayed,   press   the  

*

  or  

&

button to change the setting to  

ELAP5E

  followed by

the  

(  

button   which   will   result   in   a  

0000

  prompt

being displayed with the first digit flashing.  This is a
request   for   the   instruction   to   be   confirmed   by
entering 

5urE

 using the 

&

 and 

*

 buttons to adjust

the flashing digit and the 

(

 button to move control

to   the   next   digit.     When  

5urE

  has   been   entered,

pressing  

)

  will   reconfigure   the   instrument   to   a

Timer   and   return   the   display   to  

FunCtion

  in   the

configuration menu. 

5.5.4

Input:   

inPut

The  

inPut

  function   contains   two   sub-functions

inP

 

.

 

tYPE

 which defines the type of sensor that may

be connected to the input and 

dEbounCE

 which adjust

the amount of input noise rejection. 

5.5.5

Input type:   

inP

 

.

 

tYPE

inP

 

.

 

tYPE

 is a sub-menu in the 

inPut

 function which

defines   the   type   of   input   sensor   that   may   be
connected to the input.  To check or change the type
of input, select 

inPut

 in the configuration menu and

press   

(

   which will reveal the  

inP

 

.

 

tYPE

  prompt,

pressing 

(

  again will show the existing input type.

If   set   as   required   press  

)

  twice   to   return   to   the

configuration menu, or repeatedly press the  

*

  or

&

 button until the required type of input is displayed

and   then   press  

)

  twice   to   return   to   the

configuration menu.

One of following six types of input may be selected:

Notes:

1.

Maximum voltage input +30V.

2.

For   sensors   that   require   energising   i.e.
proximity   detectors,   switch   contacts   and
those with open collector outputs, terminals
3  & 4 of the BA577E-SS Timer should be
linked together.

3.

For the Timer to function correctly, the input
signal   must   fall   below   the   lower   switching
threshold   and   rise   above   the   higher
switching  threshold for  the  times  shown  in
the debounce section 5.5.6 below.

5.5.6

Debounce:  

dEbouncE

dEbouncE

  is  an   adjustable   sub-menu   in   the  

inPut

function   which   prevents   the   Timer   mis-functioning
when   the   input   has   noisy   edges,   such   as   those
resulting   from   a   mechanical   contact   closing   and
bouncing.       Three   levels   of   protection   may   be
selected   and   the   amount   of   debounce   applied
depends upon the type of Timer input that has been
selected in the 

inP

 

.

 

tYPE

 function.

The following table shows the minimum time that the
input signal must be continuously above the upper
input switching threshold and continuously below the
lower switching threshold to ensure  that the Timer
processes   the   input   signal.     Input   switching
thresholds are shown in section 5.5.5.
