A. General Product Configuration
1. The MB-18 is equipped with nine (9)
independent soda/water inlets (see
Figure 1 for detail). An individual
module that can be plumbed for either
soda or still water supports each nozzle
location. In addition, nozzles 3, 4 and 5
are provided with a second module that
will also support soda or still water. This
is to provide for maximum flexibility and
performance from all circuits and
products.
2. Depending on the specific use volume
at the installation, the use of either one
or two Lancer Turbo Carbonators is
recommended. Locations serving
larger drink sizes and/or higher drink
volume will require a second Turbo
Carbonator. In addition, the use of a
high capacity plain water boost system
is recommended if incoming water
pressure is below 50 psi under demand
conditions. Nozzle Inlets

3.2 PROGRAMMING AND SETUP SOFTWARE
A. INTRODUCTION
NOTE:
The following descriptions reflect Firmware Version X.Y.Z And Palm Pilot™ software version
U.V.W. Lancer reserves the right to make changes and updates as required. If you have any
questions regarding the latest versions of programs, please contact your Lancer representative.
1. The Lancer MB-18 is equipped with a serial communication port to facilitate set up, data
retrieval and maintenance. In addition an infrared wireless port is available.
2. Access to the internal functions is available through the use of a Palm Pilot Hand Held
computer along with software available from Lancer.
B. INSTRUCTIONS FOR USE OF PALM PILOT INTERFACE
1. General
The MB-18 Service Tool currently (Rev ) has four (4) basic sections. Each section
addresses specific related features:
a. ICE
Deals with both ice storage bin and ice delivery auger settings including agitation and
ice delivery speed
b. VALVE
Address carbonated/non-carbonated selection, end of pour soda delay settings,
includes parameters for selecting syrup brand and bonus flavors as well as bonus
flavor availability.
6

c. DISPENSER
Controls settings for maximum number of valves and maximum number of bonus
flavors that can be simultaneously available. Includes settings for drink top off, flavor
timeout and syrup start delay, and the beginning of the pour.
d. TEST
Includes three (3) modes: Normal, PC (portion control) Test, and Draw Test.
2. General Function
a. In all menus and sub-menus, either drop down selections are available by selecting the
down arrow or square box icon next to the desired parameter.
b. All values on the Palm Pilot will be displayed as * until the data is retrieved from the
machine.
c. Select the UPDATE button after changing the parameter to load the setting into the
MB-18. You will be prompted to verify your change prior to the change becoming active.
Select OK to accept the changes or CANCEL to return to the previous menu.
C. ADJUSTMENTS AND RECOMMENDED SETTINGS
1. ICE MENU
a. AUGER SPEED MENU
The MB-18 features three (3) pre-selected ice delivery speeds. This is to allow more
flexibility to the customer with regard to filling very large cups more rapidly while not
overfilling smaller cups.
Speed selection is via the three push buttons located on the front control panel. Speeds
are pre-set by selecting a setting from 1 (slowest) to 10 (fastest) on the drop down
menu for each of the three speeds (SLOW, MEDIUM AND FAST). The other speed
adjustment (STIR) is for the auger stir speed and is also requires a setting of 1 through
10.
b. AUGER SWITCH MENU
The auger switch menu selects whether the cup lever or the push buttons initiate ice
dispensing. Selection is via check box.
c. MAX ON TIME MENU
The max on time menu sets the maximum length of time that the auger can run. This
is to prevent accidental locking or rigging of the switch. The switch must be
momentarily released to reset.
The Ice Speed Switch Selection menu sets the time between the end of an ice dispense
and the default (middle) ice speed setting being automatically selected.
d. STIR TIME MENU
Sets the on time (in seconds) and the off time (in minutes) for both the bin agitation and
the auger.
2. VALVE MENU
a. Each nozzle position has individual controls to activate available bonus flavors and an
"overall" end of pour soda delay. In addition, there are the beginnings of some
rudimentary data collection functions. At this time it is not necessary to set bonus
flavors to the actual installed flavor. They do need to be set to some flavor in order to
be "on".
b. Nozzle positions 3, 4 and 5 have check boxes to select either/both plain or carbonated
water for each position independently. Nozzle positions 1, 2 and 6 each must therefore
be all carbonated water or all plain water.
c. Each brand position also has the option of an independent soda stop delay. This
compensates for the varied dynamics (speeds) with which the syrup flows through the
valve/nozzle system as compared to the soda/water. At this time, we would recommend
7

delays from 0.025 seconds for diet (thin) syrups to as much as 0.125 seconds or
0.150 seconds for very thick syrups (Big Red). The adjustment criteria are by visual
inspection of the flow stream during a pour cycle.
