RESET BUTTON
The MACH-Pro(Web)Com controller includes a Reset button located between the MS/TP-
Net and AUX-Net connectors on the left-hand side of the controller face.
FIGURE 19: RESET BUTTON
The Reset button is only functional when pressed with the MACH-Pro(Web)Com controller
powered down. It is not necessary to remove the cover to press the Reset button, however
a tool with a thin protrusion of at least 6 mm (0.25") in length will be required. Starting with
the MACH-Pro(Web)Com
controller powered down, there are three different results of a
Reset button press, each dependent on how long the Reset button is held down. The
firmware remains intact during all three procedures.
Table 5 details the three Reset button results.
Avoid using the Reset button unless absolutely necessary. Read and understand the
following material before using the Reset button.
TABLE 5: RESET BUTTON RESULTS
Clear Description
Non-
Volatile
RAM
With the power off, press and hold the Reset button for two seconds.
The Clear Non-Volatile RAM method resets the capacitor-backed RAM
memory, clearing Trend Log data, Runtime Log data, BACnet Address
Binding Table, NET Ins and Net Outs, and Variable present values.
Variables values go to the last written value saved in the Flash backup of
the database. (All of these items are automatically regenerated after the
controller returns to normal operation.)
Database Press and hold during a power up, and release within five seconds after
the status LED (located below the power switch) starts flashing once per
second. The Clear Database method resets the capacitor-backed RAM
(as described above), and also clears the pan file. The controller pan file
will need to be restored following this action, however the Port Setup
configuration remains intact. For MACH-ProWebCom controllers, the
resource files will not be cleared by a Clear Database.
