PARAMETER SETTING OF THE UC RELAY CARD Before applying the procedure, check whether your oven is set in Celsius or Fahrenheit degrees. For this purpose, try to set the temperature at O. If the set temperature shows 0: Celsius degrees, if it shows 32: Fahrenheit degrees. When you change the min UC relay card, there are two possibilities: - Keep the customer parameters (counters, C/ F, si mple/detailed display) * Recuperate one or more memory components from the old card and place them on the new card in the same support and in the same way. Switch Memories * Set the new card in place. * Check the configuration key. - Without keeping the customer parameters: * Change the whole card. * Programme the configuration key.

MAINTENANCE To ensure the proper, long-lasting and safe functioning of the equipment, service twice a year by qualified personnel from our company, and especially: - Dismantle burners, checking and cleaning venturis. - Clean the nozzles. - Clean the ventilating apertures. - Investigate possible leaks. - Check controls, regulation and safety systems. - Check the hydraulic circuit and condenser. 6.1 SERVICING THE CONDENSER The water injection nozzle and the temperature sensor are to be checked and cleaned regularly.

16 Page 15 3BE390692NM 10/10 7. VERIFICATION OF TEMPERATURE SENSORS SENSOR PT100 (1 point for the capacity sensor, 1 point for the core probe) Components of the sensor PT100 PT100 Temperature sensor composed of a resistance sensor with the value of 100 ohms for a temperature of 0, ohms for a temperature of 100. The varia tion of the resistance depending on the temperature is linear. The reading of the resistance gives directly the measured temperature. The sensor is not polarised. The sensor is lengthened by a copper wire. Correspondence of Temperature in C and Resistance in Ω for PT100 sensor C

17 Page 16 3BE390692NM 10/10 How to read the chart: To find the resistance corresponding to the temperature of 164 C. Find the intersection of the line 160 C and the col umn 4 C. The reading shows Ohms. Check PT100 Ω MΩ Check sensor resistance with an ohmmeter gauged at 200 ohms (less than 107 ohms for 20 ). Check the sensor insulation between one of the leads and the metal part with the ohmmeter gauged at 20 megohms (a value over 15 megohms). Check the continuity between the screen and the metal part of the sensor.

18 Page 17 3BE390692NM 10/10 8. DOOR ADJUSTMENT AND CLOSING WARNING: This adjustment must be carried out everytime the door or the door closing system is serviced (hinges, closing device...), or after a steam leak in the way of the capacity seal AND 12 LEVEL OVENS - Check that the oven is levelled. - Door closed. Level the door by unscrewing both fixation screws of the upper hinge on the oven. Screws Door - Level the door, tighten and block the screws. - Loosen the fixation screw of the upper hinge on the door. Screw Door - Push the door against the seal so that tightness is perfect. Warning! It is useless to squeeze the seal flat, it will not result in better tightness. - Block the fixation screw of the hinge. - Bring the upper distance between the door and the capacity to the lower part of the door by loosening the fixation screws of the lower hinge. At this stage, if the procedure has been properly executed, the door should be at the same height as the oven top. If not, readjust before the next step

19 Page 18 3BE390692NM 10/10 - open the door and measure the distance between the door top and the tip of the closing piston. - Measure the distance between the top of the oven and the bottom of the hook groove. Distance between the top and the piston tip Distance between the top and the groove bottom - The distance between the top of the oven and the closing hook must be 1 to 2 mm greater than the distance between the top of the door and the piston tip. If not, loosen the closing hook screw and adjust the distance LEVEL OVENS - Make sure that the oven is properly secured to the floor. Level the oven. - Door closed. Level the door by unscrewing both fixation screws of the upper hinge on the oven. Screws

20 Page 19 3BE390692NM 10/10 - Level the door, tighten and block the screws. - Loosen the fixation screw of the upper hinge on the door. Screw - Push the door against the seal so that tightness is perfect. Warning! It is useless to squeeze the seal flat, it will not result in better tightness. - Block the fixation screw of the hinge. - Bring the upper distance between the door and the capacity to the lower part of the door by loosening the fixation screws of the lower hinge.

The main consequence of this wear results in steam leaks in the way of the driving shaft, in a modification of cooking results (coloration, drying). PROCEDURE FOR CHANGING THE GASKET - Open the ventilation duct. - Unscrew the holding screw of the water deflector and remove the deflector. Screw + deflector - Install the hub puller (3 points with flat tips) and extract the turbine Turbine Hub puller Driving shaft gasket - Remove the gasket

22 Page 21 3BE390692NM 10/10 - Grease the motor shaft with Biolub code: grease (Special lubricant for the food industry) to make fitting the rings easier. - Assemble the ring with the gasket (assembly code : ). - Install the assembly on the driving shaft. Rotate the driving shaft before putting the turbine back in place. Warning: - Check gasket/driving shaft co-axiality. - Run the motors (before reassembling the turbines) to check proper positioning of the ring and the gasket (they must not rotate together with the driving shaft). - Reassembly : carry out the procedure in reverse order.

No of auto resets : This indicates a problem regarding to environmental EMC. Remember to RESET by validating this line when servicing in order to enable the customer s counter, to restart at the value adjusted in the ASS frequency. Access to the technical assistance menu. This enables, by analysing outlets and inlets to give a help to the analysis before initiating to dismantle the equipment Overheating. Check: - The operation of the technical ventilator and its ventilation direction. (The ventilator is to suck air from the technical compartment towards the back of the oven). - Cleanliness of air inlet and discharge apertures. - That aspiration is with fresh cool air.

VLVE INLETS In order to activate the outlets, one by one, so as to check their proper operation, the solenoid valve rates. Principle of activation of inlets outlets: Bring the vertical lift opposite the outlet to be checked (lower knurl) - For all that concerns the contactor, each activation of the upper knurl results in the actuation of the outlet for 0,5 S with drop out afterwards, in order to check that the coil is not stuck and operates properly. - For all that concerns the ventilation (Line 14 and line 17) : - line 14: Activation of 7 and 14 for 3s, to check the direction of rotation - Line 17: Activation of 17 and 7, then (0,5 s after) 14 for 3 s, to check the other direction. - Line 4 and 5: Drop out of 4 and 5 for 3s. - Line 24 and 25: Respective outlets supplied. - Line 23: Identical to solenoid valves. Opening of valve In with activated turbine outlet. Then closing of valve In and switching off of the turbine when the valve is closed. - Solenoid valves: A first actuation of the right knurl causes the activation (maintained) of the outlet for one minute. In case of a second action before one minute has elapsed drop out results.
