• function ‘ B.4 exceeded ’ (‘ Fn.b.4 ’) enables an internal counter for
exceeded time, which can be made visible on display by activation of
channel ‘B’ signal. To reset the exceeded counter, view the counter
on display and activate the reset (front or rear). The reset leaves the
exceeded counter at a value of ‘0’ and in ‘Stop’ mode. The exceeded
counter counts the totalized time after a certain event triggers the
start of the internal counter.
• at the ‘ Start ’ (‘ Strt ’) parameter select ‘ o.AL1 ’ to start the
exceeded counter when alarm 1 activates. Select ‘ o.AL2 ’ or
‘ o.AL3 ’ to trigger the counter on activation of alarm 2 or 3.
• parameter ‘ Format ’ (‘ ForM ’) configures the view format for
the exceeded counter. Value ‘ ch.A ’ views in same format as
the main instrument.
• function ‘ B.5 hold ’ (‘ Fn.b.5 ’) controls the hold of the display by
controlling the state of the signal at channel ‘B’. The chronometer
continues counting on the background.
• function ‘
B.6 max / min ’ (‘ Fn.b.6 ’) internally saves the maximum
and minimum times recorded of a certain cycle. Each time a reset is
activated, the instrument compares the actual reading value with the
previous saved memorized values. It replaces the minimum value if
the actual value is smaller. It replaces the maximum value if the actu -
al value is larger. Minimum and maximum values are visible through
front key UP (
5
)
(see section 1.12.5)
.
Application - a production process executes a reset signal each time
a production element has been finished. At the end of the day, the
maximum and minimum production times can be accessed.
1.12.3 Controls configuration
The ‘ Controls ’ configuration menu (‘ SnSr ’) provides configuration for
the ‘start’, ‘stop’ and ‘reset’ controls. Default configuration is activa -
tion by free potential contacts, with activation by falling edge (direct
connection to terminal 0 Vdc). The following parameters allow to
configure the instrument controls to work with other type of signals
(NPN, PNP, inductives, ...).
• ‘ Pulls for ‘Start’ and ‘Stop’ ’ (‘ PuL.S ’) - select ‘ P.uP ’ to acti -
vate pull-up resistors (needed for NPN sensors). Select ‘ P.dn ’
to activate pull-down resistors (needed for PNP sensors).
Select ‘ no ’ to deactivate pulls. Selecting a pull resistors configures
the trigger level to 2,5 Vdc.
• ‘
Activation for ‘Start’ and ‘Stop’ ’ (‘ Act.S ’) - select (‘ on_h ’) to acti -
vate the ‘Start’ and ‘Stop’ controls by rising edge. Select (‘ on_0 ’) to
activate by falling edge.
• ‘
Pulls for reset ’ (‘ PuL.r ’) - select ‘ P.uP ’ to activate pull-
up resistors (needed for NPN sensors). Select ‘ P.dn ’ to ac -
tivate pull-down resistors (needed for NPN sensors).
Select ‘ no ’ to deactivate pulls. Selecting a pull resistors configures
the trigger level to 2,5 Vdc.
• ‘
Activation for ‘Reset’ ’ (‘ Act.r ’) - select (‘ on_h ’) to activate the
‘Reset’ control by rising edge. Select (‘ on_0 ’) to activate by falling
edge. Additionally, reset signal can be configured to activate by lev -
els instead of edges
(see section 1.12.2)
. In case of activation by lev -
