6.5.10 Set time:  

5Et t

This   is   the   Timer's   setpoint.     When   controlling   an
external   event   via   the   optional  control   outputs   the
BA377E-SS will time-down from the set time to zero
or time-up from zero to the set time.

To check or change the set time, select  

5Et t

  from

the   configuration   menu   and   press  

(

  which   will

reveal the existing setting with the most significant
digit flashing.  The flashing digit may be adjusted by
pressing   the  

*

  or  

&

  button   followed   by   the

(

 button to transfer control to the next digit.  When

set as required, enter the selection and return to the

5Et t

 prompt in the configuration menu by operating

the 

)

 button. 

Note:

If  

5Et   t

  is zero  the Timer will not function

when an external start input is received or the  

&

button is operated.

6.5.11 Repeat timing cycle:  

CYCLE5

This   powerful   function   enables   the   BA377E-SS
timing   cycle   to   be   repeated   up   to   99   times   or
continuously   with   a   configurable   delay   between
cycles of up to 99 hours, 59 minutes & 59 seconds.

To   check   or   adjust   the   repeat   timing   cycle,   select

cycle5

  from   the   configuration   menu   and   press

(

  which   will   enter   a   sub-menu   containing   three

sub-functions,  

EnbL

,  

CYCL  Cnt

  and  

r5t  dELA  

which

are described in the following sections.

6.5.12 Cycle function enable:  

EnbL

This sub-function allows the repeat timing cycle to be
enabled or disabled without altering any of the repeat
timing  cycle  parameters.    To  check  or  change  the
function   select  

EnbL

  from   the   repeat   timing   cycle

sub-menu   and   press  

(

  which   will   reveal   if   the

repeat cycle function is  

on

  or  

oFF

.   The setting can

be   changed   by   pressing   the  

&

  or  

*

  button

followed   by   the  

)

  button   to   return   to   the   repeat

timing cycle sub-menu.

6.5.13 Cycle count:  

cycl cnt

This sub-function defines the number of times that
the timer cycle is repeated.   It may be set to any
number between 1 and 99, or to 00 for continuous
repetition.

To   check   or   change   the   function   select  

cycl cnt

from the repeat timing cycle sub-menu and press 

(

which will reveal two digits with the most significant
flashing.     The   flashing   digit   may   be   adjusted   by
pressing   the  

*

  or  

&

  button   followed   by   the

(

 button to transfer control to the next digit.  When

set as required, enter the selection and return to the

cycl cnt

  prompt in the sub-menu by operating the

)

 button.

6.5.14 Restart delay:  

r5t dela

This   sub-function   defines   the   time   delay   between
repeat   timing   periods.     It   is   shown   in   the   format
selected in the units function and may be set to any
time between zero and the maximum time allowed in
the selected format.

 from the repeat timing cycle sub-menu and

press  

(

  which   will   reveal   the   delay   time   in   the

selected   format   with   the   most   significant   digit
flashing.     The   flashing   digit   may   be   adjusted   by
