1.13.17 Fast access

The 'fast access' is an operator configurable menu. The op-
erator can access this menu with a single press of the front
key 'UP' (5). The configured menu entries will be accessible.
Eligible parameters to be accessed by this menu are:
• access to the alarm setpoints through the 'UP' (5) key al-
lows to read and modify the values.
• access to the maximum and minimum alarms through the
'UP' (5) key allows to read and reset the values. To reset
the memory values: visualize the value on display, press the
'UP' (5) key, when the 'rSt' message appears, press 'SQ'
(<) . The instrument will return to the memory visualiza-
tion. Press the 'LE' (3) key to exit his menu.
• access to the preset value to read and modify the value.

1.13.18 'On power up' function

The 'On Power Up' ('on.Pu') functions allows to define a se-
ries of actions to activate when the instrument restarts after
a power loss. Functions available are a delay so the instru-
ment waits a defined time before starting to measure and
control, and an automatic reset of the counter. The functions
will apply only after a restart due to power-loss, they will not
apply after a restart due to changes in configuration.
Delaying the measure and control functions gives additional
time to elements of the system who are slower, so they can
start completely before the instrument begins to acquire sig-
nal and control the outputs.

1.13.19 Key 'LE'

The 'LE' (3) key at the front of the instrument can be con-
figured to activate several functions. Only one function can
be assigned to the 'LE' (3) key. Eligible functions are reset
of the counter and the alarm unlock function (see section
1.13.15).
Example: an impulse counter activates alarm 1 when reading
reaches 153.000. Automatically the instrument activates a
reset, reading goes to '0', and relay 1 is activated to inform
that the required level has been reached. Counter remains
at 0 receives several additional impulses, related to the sys-
tem not stopping immediately. When the operator arrives,
reloads the system and presses key 'LE' to return the reading
to '0', unlocks the alarm and restarts the system.

The 'fast access' menu is not affected by the password func-
tion. This means that the configuration menu can be password
blocked, while some configured functions or parameters can
still be accessible to the operator through the 'fast access'
menu.
• Super fast access
If only a single function is selected for the 'fast access' menu,
pressing the the 'UP' (5) key will shortly display the function
name and then automatically jump to the function value.
While on delay mode, the instrument shows all decimal points
lightened and flashing, all alarms are deactivated, and there
is no signal acquisition or communications control. When the
delay time is over, the instrument starts its normal function-
ing.
