2. DESCRIPTION
Introduction
2.01 The Microprocessor Assembly consists of electrical connectors,
a 4-position DIP Switch, and related circuitry to provide control and interface
between the keypad assembly and various functional areas of an oven. The Microprocessor
Assembly is mounted to a metal plate which provides mounting facilities. A Label affixed to
the Metal Mounting Plate shows the related oven models and indicates DIP Switch toggle
positions. Refer to Figures 1 and 2.
Part Number 2402283

2.02 The conversion process consists of:
• Accessing the oven control compartment.
• Disconnecting associated wiring and removing the earlier version
Microprocessor Assembly.
• Setting the appropriate DIP-Switches on the new Microprocessor
Assembly.
• Installing The Microprocessor Assembly into the oven.
When the Microprocessor Assembly has been installed, the oven should be checked for
desired operation.
Unpacking
2.03 The Microprocessor Assembly was checked before leaving the
factory. Inspect the shipping container carefully for evidence of improper
handling during shipment. In case of damage, make an immediate claim to the dealer
or distributor from whom the unit was purchased. If the Microprocessor Assembly was
shipped to you, notify the carrier without delay and file a claim.
CAUTION
Before removing the Microprocessor Assembly from the
anti-static bag, attach the static strap to your wrist
and a good ground.

Procedure
Open the shipping carton. Attach the supplied electrostatic
discharge wrist-strap to a good ground. This prevents
equipment damage caused by static discharge.
Remove the Microprocessor Assembly from the shipping carton
and anti-static bag. Use the open shipping carton or a
Static Mat as a clean reduced-static work area to place the
Microprocessor Assembly.
Refer to the Data Plate on the oven and note the Model
Number. Refer to Figure 3.
Refer to the keypad used on the oven. On the lower portion
of the keypad is printed Menu Select (late version) or it
is blank (non-Menu Select, early version). This indicates
the type of keypad used. Refer to Figure 4.
The keypad identification and oven model number are used to
identify the appropriate DIP Switch and related settings.
Refer to the DIP Switch Setting Information Label on the
Microprocessor Assembly and identify the specific oven Model
and associated DIP Switch setting. (Figure 5).
Place the Microprocessor Assembly with the component side
facing up. Locate the 4-position DIP Switch (Figure 5).
Set each switch to the correct position as shown on the
Switch Setting Information Label.
For Installation information into:
A. CTX Gemini (DZ) Ovens, refer to Paragraph 4.01.
B. CTX Hearth Bake (HB) and Triphase Ovens, refer
to Paragraph 5.01.
