The IntelliSwitch allows various system parameters to be set in the field. They are:
a. Switchover Pressure
b. Units of Measure
c. Keypad Security Lockout
d. Serial Port Enable
Switchover Pressure
The switchover pressure is factory set to optimize performance based on the outlet pressure range of the
system. These factory settings are shown in Table 3 in grey highlight. The switchover pressure can be changed
by setting DIP switches SW1-1 through SW1-9 on the Electronic Circuit Board inside the IntelliSwitch. The
switchover pressure can be field set up to 500 PSIG. It is important that the switchover pressure be set higher
than the desired outlet pressure required by the application, but not higher than the pressure capability of the
gas source. Table 3 shows the DIP switch settings to establish the desired switchover value.
To access the DIP switches, REMOVE AC power from the system. Remove the knob on the outlet pressure
adjustment regulator by carefully lifting the center label on the knob and removing the nut. Using a Phillips
screwdriver, remove the 4 screws and washers holding the front panel. Unscrew the nut on the outlet pressure
adjustment regulator being careful not to allow the front panel to fall. There are two long studs attached to
the inside of the front panel that will allow hanging of the panel to the bottom of the enclosure.
Table 3 shows some typical switchover settings. To set values other than those in Table 3, use Table 2 or
contact CONCOA Customer Service for assistance. Using Table 3 and Figure 3, set the switchover pressure
DIP switches to the desired value. When completed, place the front panel back into place being careful not to
pinch any wires. Attach the large nut to the Outlet Pressure Adjustment Regulator first. This only needs to
be finger tight. Re-install the 4 screws and washers holding the front panel. Attach the knob to the regulator
using the nut and reapply the label. The nut holding the knob should be tightened securely.
Re-apply AC power. The new switchover setting may be viewed in test mode.
Note: Table 3 shows values in PSI. To set values in BAR or MPA, convert the numbers in the table. For PSI
to BAR, divide the PSI value by 14.5; for PSI to MPA divide the PSI value by 145.
