CONNECTING THE INTELLISWITCH
The key to any successful system installation is understanding the application and sizing the components
properly.
The inlets and outlet on the IntelliSwitch are 1/2” Female NPT fittings. These fittings have an anti-rotation
plate around them to keep them from twisting during installation. However, it is strongly recommended that
two wrenches be used when tightening external devices to these fittings.
The IntelliSwitch uses four mounting tabs for mounting to a wall or panel. Refer to Figure 8 for the
dimensions of the system. Anchor the IntelliSwitch securely to a wall or panel at a height adequate to
conveniently connect a manifold or pigtail.
If using an external air-driven IntelliSwitch, connect the air source to the air inlet on the bottom of the
system.
Note: Air used for this system must not contain moisture or oil. Air pressure should be in the range of 65-85
PSIG and must not exceed 100 PSIG.
Figure 1 shows a typical installation.
Once all mechanical connections are made, connect the Remote Alarm, and serial device to the IntelliSwitch.
If using an external air-driven IntelliSwitch, turn the air source on at this time.
Finally connect AC power to the IntelliSwitch. The system is factory set to operate at either 115VAC 60hz or
230 VAC 60hz. Connection of the IntelliSwitch to the incorrect input voltage will damage the product and
void any warranty.
Pressurize both sides of the system; if using internal process gas-driven IntelliSwitch, pressurize the right side
first. The inlet pressure readings will appear on the two 4-digit displays. If necessary use the Bank Select
pushbutton to choose the side considered to be the primary gas source. If gas pressures are on before the
system is powered up, the IntelliSwitch will default to the left side as the primary side.
Using the outlet pressure adjustment knob, set the desired delivery pressure. The value will appear on the 3-
digit display.
