Initial Startup
1. Ensure the PGM control enclosure and all of the
proper connections to and from the control enclo-
sure have been made. Ensure fittings are tight.
2. Read and understand the Operation and User
Interface sections of this manual along with the
related manuals.
3. Continue startup with Step 2 in Standard Startup.
Standard Startup
1. Carefully inspect the entire system for signs of leak-
age or wear. Replace or repair any worn or leaking
components before operating the system.
2. Press the Stop button on the control enclosure.
3. Turn on air and electrical power to the system.
4. Turn on the main power to supply power to the
PGM.
5. Check Interface Signals: If this is a new installa-
tion, power on each system input and verify that
each input is being received. See Appendix B - I/O
on page 98.
6. For heated systems, open the dispense valve over a
waste container while the system is heating up. This
will prevent a pressure build-up caused by fluids or
gases expanding from the heat.
7. Turn on the material supply system.
