3.6 OPTIONAL CONTROL OUTPUTS
3.6.1 Programming and adjustment
The BA364D timer can be supplied with two
solid state, single pole control outputs. These
may be independently programmed to open and
close when various timer functions occur.
See section 1.9.5.1 for details of intrinsic safety.
For simplicity Fig 3.4 shows the programmable
functions for one control output. The second
output is identical.
The following table summarises each of the
control output programme functions and includes
a cross reference to more detailed information.
Again only the functions on control output 1 are
listed.

3.6.2 Control output enable: ‘EnbL’
This function allows the control output to be
enabled or disabled without altering any other
parameters. To check or change the function
select 'EnbL' from the control output sub-menu
and press
P
which will reveal the current setting.
The function can be changed by pressing the
Up

3.6.3 Control output on at:
‘OP1:On’ and ‘OP2:On’
The control outputs are very versatile and may be
programmed to turn on (close)
when the timer is
started, stopped, reset or the elapsed time equals
the programmed set time. To define when a
control output closes select ‘OP1:On’ or ‘OP2:On’
from the control output sub-menu and press
P
which will reveal the current setting. Pressing the
Up
or
Down
button will scroll through the four
options:
Display Control output closes when
‘StArt’
The timer is started
‘StOP’
The timer is stopped
‘rESEt’
The timer is reset
‘SEt t’
The elapsed time equals set
time setpoint SEt t.
When the required option has been selected
press
E
to enter the selection and return to the
control output sub-menu.
Note:
When the timer elapsed time equals the
set time ‘SEt t’, an internal stop signal is
automatically generated and all actions
associated with STOP are performed.
