At this point, the Controller, the connections and mot of the user’s hardware
will have been tested. The final procedure is to check out the machine motion
or process controlled by the actual User Program.
The basic approach initiates testing with the least amount of machine motion.
Only some outputs are allowed to generate machine motion. Thus additional
machine motion can be added gradually, thereby allowing any problems to be
detected more easily under more controlled conditions.
Before continuing, review the User Program. After this is completed, the final
system checkout can begin. The Programming and Operations Manual,
publication 1772–804 contains programming information and Processor use
with the 1770–T3 Industrial Terminal.
Final System Checkout
WARNING: When machine motion is generated, an alert
competent person must be ready to operate an Emergency Stop
switch, which will de–energize the Master Control Relay. This
removes all power from the machine.
Perform the final system checkout as follows:
1.
Turn the Processor’s Mode Select Switch to the PROG position. Press
[SEARCH] [
↑
] to display the first rung in memory. Press [CLEAR
MEMORY][9][9] to clear the entire Mini–PLC–2/15 Processor memory.
when the memory has been cleared, the END statement will be displayed.
2.
Enter the User Program into memory. Check the program instructions to
ensure they have been entered correctly.
3.
Support Processor memory with battery backup. Remove System and I/o
power.
4.
Make a list of output devices that can be independently tested without
causing danger to personnel or the machine. This list would include such
items as coolant pumps, fans, and indicators.
5.
Chose one or a group of output devices from the list and reconnect them
for full operation.
6.
Restore System and I/o power.
7.
Turn the Mode Select Switch to RUN or RUN/PROG. Actuate the
required inputs to operate one of the chosen output devices.
