Oven, including programming nine products, operation of the oven, and manually

programming the oven.

Explanation of the Control Panel:

POWER SWITCH

Turns the oven on and off.

STATUS DISPLAY

Displays the oven status.

NUMBERED KEYS

Numbered 0 to 9 these keys contain the programs that, when

selected, will run the oven.

SHELF KEYS

Labeled A to E these keys indicate which shelf the product is placed

on, A being the top shelf.

"MAN PROG"

Short for Manual Program, this key allows the operator to enter a

The display will now read:

SELECT PRODUCT OR

READ/CLEAR TO PROGRAM

Energy Saving Note: It takes approximately 8-15 minutes for a half size oven to heat to the

desired temperature (approximately 15-20 minutes for a full size oven). Consider turning the

oven off if you do not plan to use the oven again for 2 or more hours.

Entering a Manual Program

To enter a Manual Program, press the Man/Prog key. This will give you an 11

, but temporary

program. Manual Programs are lost when the oven is turned off, or when a new Manual

Program is entered. The Manual Program will also be erased if you press the Read/Clear Key.

The screen displays will walk you through manually programming the oven. The programming

functions are very similar to pre-setting programs.

Programming the Purple Plus

Convection Oven

The following procedures are step-by-step instructions for programming the Purple Plus for up to

TEN PRE-SET PROGRAMS. Additional programming capabilities exist, if the need arises.

Please contact the Lang Factory (Training and Corporate Services).

Step 1:

•

Turn the power switch on. If the oven is already on, press the Read/Clear key until the

following screen is displayed:

SELECT PRODUCT OR

READ/CLEAR TO

PROGRAM

XX:XX PM XXX F

Step 2:

•

Enter the Password. The default password is 1 6 2 7 3 8.

•

The display screen will now read:

A: SET TIME

B: SET DATE

C: PROGRAM PRODUCTS

D: NEXT MENU

Step 3:

•

Set Time: Press the “A” key to set the time. This is the time that is displayed on the screen.

•

Set Date: Press the “B” key to set the date. This is the date that is displayed on the screen.

•

Program Products: Press “C” key to enter the programming mode.

•

Press the “D” key to advance to the next display screen:

A: EDIT ACCESS CODE

B: EDIT READY ZONE

C: EDIT PRODUCT MATCH

•

These functions are available as options to fine tune (customize) the oven operation to a

concept’s specific needs. All functions have factory pre-set defaults.

Press the “A” key to Edit the Access Code. The display will direct you to enter a 6-digit

code, and then to repeat entering it to verify it.

Press the “B” key to Edit the Ready Zone. The Ready Zone is a feature that alerts the

user when the oven temperature has been reached for a newly selected program. The

default is five degrees, which means that the beeper will sound to signal “ready” within

five degrees (up or down) of the actual programmed temperature. This is an alert. For a

specific concept, when efficiency dictates a different alert, this feature can be utilized.

(Example: Set the Ready Zone alert at 10

the required temperature to alert the

operator to stage product to place in the oven.)

Press the Read/Clear Key to return to the former screen.

Step 4:

•

Press the “C” Key to Program products. The display screen will now read:

PRODUCT PROGRAM MODE

SELECT PRODUCT

NUMBER 0-9

Step 5:

•

Select a number from one to nine, and press the key corresponding to that number.

•

If a Product Key selected already has a program, the screen will display:

EDIT PRODUCT?

1= EDIT OR 2=DELETE

NXX TX XXXF CX

XX:XX:XX PXXX F-XX

(

Note: In line 3 and 4 in the above screen, the product program is displayed. Line 3: The N

refers to the Product Number. The T refers to the tier. The xxxF is the temperature. The C is

the cooking curve. Line 4 : The first six digits is the program bake time. The P is the Pulse-

how much of each 100 seconds of time the fan is to be on. The F-xx is fan high or fan low.

•

If you select Edit, follow through each screen making any changes as you go.

•

If you select Delete, the program will be deleted, and the next screen will display the

programming and editing choices A-D on one screen and A-C on the other.

Step 6:

•

If you selected a product number to program which has no program, the screen will display:

ENTER COOKING TEMP

100 TO 450 F

N0X T1 XXXF

Step 7:

Enter the desired cooking/baking temperature. The screen will automatically advance to the next

display:

ENTER COOKING TIME

HR:MIN:SEC

NOX T1 XXXF C0

Step 8:

Enter the cooking time and then press E to advance to the next screen:

ENTER COOKING CURVE

0 TO 100%

N0X TI XXXF CO

Step 9:

Enter the desired cooking curve. The cooking curve is a unique heat-compensating feature.

Refer to the Lang “Unique Baking Solutions with Lang Convection Ovens” for an explanation.

Once you have entered the cooking curve, press the E key or Read/Clear Key to advance to the

next screen:

ENTER FAN SPEED

1=HI 2=LOW

NOX TI XXXF CXX

XX:XX:XX PXXX F-XX

Step 10:

High fan speed is approximately 1700rpm, and low fan speed is approximately1400 rpm. Some

products may bake more evenly with a lower fan speed. If you are creating a NO FAN program,

you will probably want the LOW Fan Speed, since the fan will activate when there is a call for

heat to maintain temperature during the bake cycle. Once you have entered either 1 or 2, the

next screen will automatically appear:

ENTER FAN PULSE RATE

0 TO 100%

NOX T1 XXXF CXX

XX:XX:XX PXXX F-XX

Step 11:

The Fan Pulse Rate is a true variable pulse. Determine how many seconds of each 100-second

block you desire the fan to be on, and enter that number. (Example: If you desire the fan to be

on all of the time, enter 100. If you want the fan off all of the time, enter 0. Any number

between 0 and 100 that you enter will be the number of seconds in each 100 second block that

the fan will be on.)

Note: In the Fan OFF mode, the fan will cycle on ONLY when there is a call

for heat to maintain temperature during the bake cycle.

CONTINUE TO TIER 2

1=YES 2=NO

N0X T1 XXXF CXX

XX:XX:XX PXXX F-XX

Step 12:

If you press 1, you will go through the same sequence as outlined above. If you press 2, the next

screen to automatically appear is:

A: SET TIME

B: SET DATE

C: PROGRAM PRODUCTS

D: NEXT MENU

Step 13:

If you have more products to program, press the C key and continue through the programming

mode. If you have finished programming, exit the programming mode by pressing the

Read/Clear key, which will automatically display the next screen:
