See Figure 2-2. The door interlock valve (11) shuts the system down if
the door is opened. The following steps describe what happens:
1. When the door is opened, the door interlock valve (11) exhausts the
pilot on the pilot valve (14), which closes the coating material
shuttle (12) and grounds out the system.
2. The same air passes through the door interlock valve and through the
shuttle valve (19).
3. The shuttle valve (19) sends a pilot to the air release valve (6)
allowing air to flow to the air motor of the pump (5).
NOTE: The air to the air motor should be the same pressure as the
system air. If the system air pressure exceeds the coating material inlet
pressure and the spray device is triggered, the coating material pump will
purge itself, even though the coating material shuttle is closed. This
feature is useful when changing color in the Iso-Flo system.
Table 2-2 provides the specifications and operating requirements for the
Compact Manual Iso-Flo system.
