2. PARAMETER SETTING OF THE UC RELAY CARD

2.1 GENERALITIES

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. Select DRY mode.

If the set temperature shows O: 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.

6. VERIFICATION OF TEMPERATURE SENSORS

PROBE PT100 (1 point for the capacity probe, 1 point for the core probe).

Component of the sensor PT100

PT100

Temperature sensor composed of a resistance sensor with the value of 100 ohms for a temperature of

0°, 138.5 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.

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 column 4°C.

The reading shows 162.53 Ohms.

Check

Ω

PT100

M Ω

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.

7. DOOR ADJUSTMENT AND CLOSING

WARNING: This adjustment must be carried out everytime when the door or the door closing system is

serviced (hinges, closing device...), or after a steam leak in the way of the capacity seal.

7.1 6 & 10 LEVEL OVENS

- Check that the oven is levelled.

- Door closed. Level the door by loosening both fixation screws of the upper hinge on the oven.

- Level the door, tighten and block the screws.

- Loosen the fixation screw of the upper hinge on the 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

- Open the door and measure the distance between the top of the door 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.

7.2 20 LEVEL OVENS

- Make sure that the oven is properly secured to the floor. Level the oven.

- Door closed. Level the door by loosening both fixations screws of the upper hinge on the oven.
