10.3.9  Alarm delay:   

dELA

This function enables activation of the alarm output
to be delayed for a fixed time following the alarm
condition  occurring.    The  delay  can  be  set  in  1
second increments up to 3600 seconds.  If a delay is
not required zero should be entered.

To adjust the delay select 

dELA

 using the 

&

 or 

*

push  button  in  the  selected  alarm  sub-menu  and
press 

(

 which will reveal the existing delay time in

seconds with one digit flashing.  The required delay
time can be entered using the 

&

 or 

*

 push button

to  adjust  the  flashing  digit  and  the

  (

 button  to

transfer  control  to  the  next  digit.      When  set  as
required press  

)

 to enter the value and return to

the 

dELA 

prompt in the alarm sub-menu.

The alarm annunciator will start flashing immediately
an alarm condition occurs and will continue for the
delay  time,  after  which  the  alarm  output  will  be
activated  and  the  alarm  annunciator  will  be
permanently activated.

10.3.10  Alarm silence time:   

5IL

The alarm silence function is primarily intended for
use  in  small  installations  where  the  alarm  output
directly operates an annunciator such as a sounder.
When  the  alarm  silence  time  is  set  to  any  figure
other than zero, the BA588E Rate Totaliser 

(

 push

button becomes an alarm accept button.

After  an  alarm  has  occurred,  operating  the

(

 button will cause the alarm output to revert to the

non-alarm condition for the configured alarm silence
time.    When  an  alarm  is  silenced  the  alarm
annunciator will flash until the silence time expires.

To adjust the alarm silence time select 

5iL

 using the

&

 or  

*

 push  button  in  the  selected alarm  sub-

menu  and  press  

(

 which  will  reveal  the existing

alarm silence time in seconds with one digit flashing.
The required silence time can be entered using the

&

 or 

*

 push button to adjust the flashing digit and

the  

(

 button to transfer control to the next digit.

When set as required press  

)

 to enter the value

and return to the 

5iL

 prompt in the alarm sub-menu.

10.3.11 Flash display when alarm occurs:   

FL5H

In  addition  to  the  two  alarm  annunciators  on  the
lower  left  hand  side  of  the  Rate  Totaliser  display
which show the status of both alarms irrespective of
which input is being displayed, this function provides
an even more conspicuous indication that an alarm
condition has occurred.

When enabled and the Rate Totaliser is displaying
the  input  on  which  the  alarm  has  occurred,  the

fla5h

  function  alternates  the  rate  or  total  display

between  the  numerical  value  and  the  alarm

identification.    For  example  if  alarm  1  has  been
activated by a rate alarm occurring on input A the
rate display will alternate between the numerical rate
value and  

AL1

, plus the input identification  

in - A

 if

5td

  has  been  selected  for  the  lower  display

configuration   

di5P-2

 

   See  5.11.

Note:

When an alarm occurs on one input the flash
function will only be seen when viewing that
input, not when the Rate Totaliser is showing
the  other  input  or  the  composite  display.
However, the two alarm annunciators, which
indicate  the  status  of  each  alarm,  are
activated irrespective of which input is being
displayed.

To enable the function select  

FL5H

 from the alarm

sub-menu using the 

&

 or 

*

 push button and press

(

 to check or change the function.  The 

&

 or 

*

push button will toggle the function between 

oFF

 and

on

, when set as required, press the  

)

 button to

return to the 

FL5H

 prompt in the alarm sub-menu.

10.3.12  Access Setpoints:  

AC5P

This  function  activates  a  separate  menu  that
provides direct access to the alarm setpoints from
the totalising mode by simultaneously operating the

(

 and  

*  

buttons.    An  operator  can  therefore

adjust the alarm setpoints without having access to
the configuration and alarm sub-menus.  Protection
against  unauthorised  or  accidental  adjustment  is
provided  by  a  separate  optional  security  access
code.

Using the
