SAMPLING PROGRAM
MENU OPTIONS
GENERAL
All of the sampling programs have the same menu options.
Programs are constructed or built by editing the existing
program sampling menu options and saving those changes
as a modified program. The sampling menu options are
accessed through any of the sampling programs, shown in
the VIEW/EDIT PROGRAMS menu. Select a sampling
program such as PROGRAM #1 and press the ENTER key.
The display will change to read:
NOTE: You may make only one selection in each menu
option.
Select PROGRAM START and press ENTER. The
display will change to read:
PROGRAM START
Allows the operator to change how the program starts:
immediately, with a delay or through the use of another
device. There are two options; DELAYED START and
REMOTE & DELAYED START.
Select DELAYED START and press ENTER: The display will
change to:
DELAYED START
Allows the operator to input the time delay for starting the
program once the START button is pressed. The parameter is
hours and minutes 0-167:59. If you want the program to start
immediately upon pressing the START button input 0 and
press ENTER. To start after a delay or waiting period input
the desired time. If the desired delay time is 40 hours and
0 minutes input 4000 and press enter. If the desired time is
5 minutes of delay time input 5 and press enter.
REMOTE & DELAYED START
Allows the operator to start the Composite Sampler through
the use of another instrument using the REMOTE CONTACT
CLOSURE (see Figure 2) located on the exterior right hand
side of the unit. The other instrument must be able to either
close or short the contacts (dry contact closure) or generate a
pulse. Some of the instruments or devices that may be used
to start the Composite Sampler remotely are: level sensors or
float switches, pH meters or flowmeters.
Using the remote start component of this feature you can
sample a water source upon the occurrence of an event such
as a rain storm or increase in water flow or pH.
The delayed start component of this feature allows the operator
to add a time delay once the contact closure or remote signal
has activated the unit. This feature can be used to delay the
start of a sampling program until an event causes the water
source being sampled to change. An example of this would
be a rainstorm upstream of a water source. It may take 15
minutes before the water from the rainstorm affects the water
source you are sampling. You do not want to
sample the water source until it is affected by the incoming
water. You can use a float or level switch to sense an increase
of water level and remotely turn on the Composite Sampler
and the time delay to cause the program to wait before taking
the first sample to allow the waters to mix. The use of this
feature requires the Remote Contact Closure Accessory
Model No. 7580-60.
See the ACCESSORY section for details.
When you select REMOTE & DELAYED START and press
ENTER, the display changes to:
