Special Control Functions
User Lockout
User Lockout is achieved via the position of the LOCK
jumper on the board header. Locate the header on the
board (shown next column) and place the jumper in the
desired position. In the Locked position all menus in this
document are locked out, and the unit will only allow
brewing functions. There are two versions of the
header, 10 pin and 2 pin. Both configurations are shown
next column.
System Restore Function
This function will restore a Precision Brew
®
unit to its
original factory settings. To activate system restore,
power on the unit while holding in the DOWN button
on the keypad (use the keypad that controls the RIGHT
side for a double unit).
Continue holding the DOWN button and the display
will scroll “rEStorE” to indicate that a system restore is
about to happen. If the DOWN button is released at this
point, the restore is cancelled. If the button hold is
continued, the display will scroll “donE” to show
completion of a system restore.
Upon a successful restore, the original factory settings
will override all changes. The brew counters are not
affected.
Factory Specific Features
The following sections describe features that are not
intended to be used by the end user. These features,
instead, are intended to help American Metal Ware set
up and test the machine.
Factory/Field Test Menu
This menu is intended to check product functionality
both at the end of the factory line and in the field. The
control must be completely OFF (both sides) to enter
field test. This mode is entered by pressing and holding
the UP key and the LARGE BREW key on the keypad
(use the keypad that controls the RIGHT side for a
double unit) for 6 seconds. Once the menu is entered,
the unit will start with an LED test that lights all LEDs
and segments on the display.
Proceeding through the field test is done by pressing
the ON/OFF key (RIGHT side if a double unit). Each time
this button is pressed, the test will advance to the next
step. For the output test, use the UP and DOWN keys to
select the desired output.
Refer to the table on the following page for operation.
Field Test Mode exits after stepping through all modes
only- there is not a timeout.
