5.5.9 Access Setpoint: ‘AcSP’
This function activates a separate menu that
provides direct access to the control output
setpoints when the clock is in the display mode.
See section 5.5.10 for a full description. An
operator may therefore adjust the setpoints
without having access to the programme menus.
Further protection is provided by a separate
security code.
This direct access menu is enabled and a
separate security code entered from the 'AcSP'
function in the main programme menu as shown
in Fig 5.3. To change the menu parameters
select 'AcSP' from the programme menu and
press
P
. This will display the enable prompt
'EnbL'.
Pressing
P
again will reveal if the direct access
menu is 'On' or 'OFF'. The
Up
or
Down
buttons
will toggle the display between the two
conditions.
If 'OFF' is selected, the operator will not have
direct access to the setpoints when the BA364D
clock is displaying time. Return to the 'AcSP'
prompt in the main menu by pressing
E
twice.
If 'On' is selected, the operator will have direct
access to the control output setpoints when the
BA364D is displaying time via a separate menu
and optional security code. To define this four
digit numeric code press
E
to return to the 'EnbL'
prompt followed by the
Up
or
Down
button to
select the access code prompt 'AcCd'. Pressing
P
will then reveal the current security code with
one digit flashing. The code may be changed by
operating the
Up
or
Down
push-buttons and
pressing the
P
button to transfer control to the
next digit. Finally press
E
twice to enter the new
security code and return to the 'AcSP' prompt in
the programme menu.
Entering code 0000 will disable the security code
allowing direct access to the setpoints in the
display mode by pressing the
P
and
Up
buttons
simultaneously.
New instruments with control outputs are
supplied with the security code set to 0000
