1 -INTRODUCTION

1.1 - PURPOSE OF THIS MANUAL

The purpose of this Manual is to provide information of new Ovens Power board OVC3000.

1.2 - WARNINGS

All work with open appliances must be done with the mains supply

disconnected.

The intervention on electrical equipment should only be performed by

qualified personnel.

Before an operation in a device, check the efficiency of the system housing

through means of appropriate equipment. As an example, refer to the

indications described / illustrated in the portal Electrolux Learning Gateway

(http://electrolux.edvantage.net).

After intervention, verify that the conditions have been restored to the

safety switch apparatus, as just leaving the assembly line.

In the case of manipulation / replacement of the PCB, use the ESD kit (Code

405 50 63-95/4) to prevent electrostatic discharge damage the circuit board

see SB No. 599 72 08-09

2 -OVERVIEW

The electronic board OVC3000 introduces new concepts of power board to the ovens.

New electronic concept for common cavity appliances (Apollo, Ariane, Sputnik, GV)

•Optional replacement of OVC1000/OVC2000 in the current range of Access appliances (*)

•OVC2000 replacement for single cavity appliances with food probe functionality (*)

•MACS –Communication

•According EN60335-1: Amendment 2

•According standby requirements from 2010 (0.460 W, POB stand alone)

•Reinforced isolation for Food Probe Module (Class II)

(*) NOTE : Only from the standpoint of new production, in service you cannot replace the old cards with the

new.

2.1 - RANGE OF APPLICATION

OVC3000 is a power board for single oven, and in the models with microwave and steamer with limited

functions. The unit can control 4 heating elements, 5 small loads. The food probe functionality and 3 extra

relays are covered by an optional board (FPM).

The power board OVC3000 was designed to be used in the Apollo, Ariane, Sputnik, Global Vision, Century,

Access, FS Access and Matrix platforms to control the Non Pyro, Pyro, Microwave and Steam single ovens.

4 - TECHNICAL FEATURES

4.1 - MAIN FEATURES (*)

•Modular system: Power board OVC3000 + Food Probe Module FPM:

•Pollution degree 2

•Ambient temperature : max. 105°C

•With extension board (FPM)

•Supported appliances

Non Pyro

Pyro

Microwave

Steam

4.2 - FUNCTIONALITY(*)

•Max 4 heating elements (eg. Grill, ring, top, bottom)

•5 small loads

•Isolated MACS communication with UI

•1 sensor for oven cavity (PT500)

•Analog inputs for door switch, telescopic runners detection

•Pyrolytic (door lock)

•Microwave function

4.3 - FPM (FOOD PROBE MODULE) EXTENTION FUNCTIONALITY (*)

In the appliances where was applied the Food Probe or more other functions (e. g. steamer or Magnetron),

in order to cover all the functions it was necessary to add one of the following three FPM.

•- Food Probe Module basic

- control of the external food probe

•- Food Probe Module expanded

- control of the external food probe

- additional relays (2 additional loads) -> e.g. applicable for steamer

•- Food Probe Module full

- control of the external food probe

- additional relays (3 additional loads) -> e.g. applicable for models combined with microwave

(*) NOTE : Depends on the type of appliance, refer to the wiring diagram specific.
