op1  off

Control output 1 may be configured to turn 

off

 when

the Timer enters any one of the five Timer states.
Alternatively, the phase of control output 1 may be
reversed, by selecting an 

n

 state which will cause the

control output to turn 

off

 when the Timer enters  any

other than the specified Timer state.   Timer states
are shown in Fig 13.   

To   define   when   control   output   1   turns

on

 delay time:  

op1  dELA

Control   output   1   may   be   delayed   from   turning  

on

(output closed) for a fixed time following the selected
condition occurring. e.g. when the Timer enters the

run

  state.       This delay is useful for many control

applications, for example when the control output is
connected  to  the  reset   terminals RS1  and  RS2  to
automatically reset the BA374G Timer.    

   

The  delay can be adjusted in 1 second increments
up to 32,400 seconds, which is 9 hours.  If a delay is
not required zero should be entered.   To adjust the
delay select 

op1 dELA

 from the control output 1 sub-

menu   and   press  

(

  which   will  reveal  the   existing

delay time with one digit flashing.  The flashing digit
can be adjusted using the

button   to   move   to   the   next   digit.     When   the

required delay has been entered, press 

)

 to return

to the control output 1 output sub-menu.

6.5.26 Control output 2 (optional):   

op2

Control output 2 is an optional, galvanically isolated
solid   state   switch   contact   which   can   be
independently configured to turn 

on

 and 

off

 when the

Timer is any of it's five states.         It's functions and
configuration   are   identical   to   control   output   1
described in sections 6.5.21 to 6.5.25

The control output status is shown by the '2' control
output display annunciator. 

6.5.27 Reset   grand   total   from   within   the
