Operation 4
- Time at which the pump will wait for an input
- Waiting for an open contact or a closed contact
Example 4: 2.00 min Wait #1 Closed.
To program this example:
• press the Add soft key.
• press the Wait soft key.
• key in the time for the wait to begin, 2.00, and
press Enter.
• press the close soft key.
The program waits at time 2.00 minutes until input
#1 is closed. If input #1 is already closed at time
2.00 mins, the program will continue. If input # 1 is
not closed, the program will wait. During the time
that the program is waiting, the display will show
the total run time and the time that it has been
waiting.
If a pump is waiting for an input, pressing Cancel
will simulate an input and the program will con-
tinue.
Out
In this menu, you can program each of the outputs
in the system to open or close. The out-puts are
numbered 1, 2 and 3 and are used to send signals
to other equipment in the system, for example an
auto sampler or a chart recorder. By having the
output operations as part of the method program,
the same sequence of contacts repeats every time
the method program is run.
There are three pieces of data for this menu.
- Time at which output is operated
- Output number
- Output opened, closed or pulsed
Each of the outputs can be made to open, close or
pulse. Pulse means that the output will change its
current state for 0.6 of a second.
