%u - Unique ID
%r - Reprint ID
%i - Scale ID
Additionally, you can specify 02 to zero pad a number by a certain amount.
So, D%04r would produce D0001 for Reprint ID 1.
5.8. 2 Valve Sensing (Optional)
Valve Sensing allows your NVS system
to communicate directly with the PLC
that controls the valve. You can have a
dry contact connected to your NVS that
provides a low-voltage signal +12V to
the NVS when the valve is either open
or closed. As soon as the valve opens,
we will take pictures of the truck on the
scale. If we have not received a ticket
from the Apex system before a user
defined timer expires, then we will
generate a Valve Alert and save the
previously generated pictures associated with this Report. The file format is
similar to that of the Apex configuration on the previous page.
You can configure the timer to behave in one of two ways.
1. Initiate the timer when the valve closes for the first time. This is useful in
Cement installations where loading happens in one place. In other words,
the truck never moves. The default timeout of 120 seconds should suffice
in this scenario.
2. Initiate the timer when the truck leaves the scale. This option requires
that you have Scale Sensing properly configured. This is useful in
Asphalt installations where the loading happens on one scale but several
different silos. Obviously, the timer should be much shorter ( 0-10
seconds) in this scenario.
