Keypad Security Lockout
The IntelliSwitch has a built in feature that allows a user to lock the buttons on the front panel so the current
setting cannot be changed. The factory default setting for this feature is disabled. This feature can be enabled
by setting DIP Switch SW3-4 to “ON”. With the feature enabled and the system turned ON, the system
starts a 5-minute timer. If no button is pressed for 5 minutes, an audible beep will sound 3 times after which
the buttons will become inactive. To re-activate the buttons, the BANK SELECT button must be depressed
for 5 seconds. After 5 seconds, the system will beep 3 times and the buttons will again be active.
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.
Using Table 5 and Figure 4, 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 setting may be viewed in test mode.
