Reduce the temperature of the ambient air. The temperature of the air supply may not exceed 40°C/110°F. One phase is missing (only with three phase supply) Check the fuses Power board defective Check power board AP3 Logic board defective Verify logic board operation al3 No reaction on turning the control knob Potentiometer is defective Check potentiometer A03 Heat rating switches off and on within minutes, fan is working Air cooling system is hindered Make sure that air supply and air exit are not hindered, clean air slots Fan is dirty Clean fan AF1 Heat rating switches on and off within minutes, fan does not work Fan defective Fan checking defective Check fan AF2' ' Heat rating switches on and off within minutes (after a long and constant use) Coil is overheated, heating area is too hot Empty pan Overheated oil in the pan Switch off cooker, put pan away and wait until the heating area has cooled down. (for ex. spoons) are heated on the heating area 1) In order to verify whether the pan is appropriate use a magnet which should stick to the bottom of the pan. If it does not, your pan is inappropriate for induction cookers. Choose pan material that is recommended for induction appliances. 2) The cooling system starts to work when the temperature of the cooling plate is higher than 55°C/160°F, it reduces the checking of the power in order to hold the power board in normal working conditions. 7.5 Fault repair Detained instruction of the steps in order to repair faults (see lisfFaultfinding*) m circuit has occured. Make tt circuit. If it is the power boai yl5¥ tKe^o^kerTCheek with an ohmmeter whether a shoff is test in “ON" and “OFF"-positions. Locate the short •d, replace it. Verify the operation. AP2 Check load +24 VDC ST 1/1: „24 VDC, ST 1/4 ND (on power prints K016, K031 and on logic prints K018) If wrong, replace logic board. Sign „enable" (ST 1/2) and low” (ST 1/3)a. If wrong, replace logic board KO18, Check components (see “Test components") AP3 Sign “low” (ST 1/3) and highO'* (ST~1/5)a If wrong, replace logic board K018, otherwise check components on the power board (see “Test components"). AL1 Verify signs “enable” (ST 1/2) and 'low" (ST 1/3)a. If wrong, replace logic board K018. Ai.2 Replace logic print AL3 Check signs “low- (ST 1/3) and “highO” (ST 1/5)a. If wrong, replace board print k0l8 otherwise replace power unit (s. AP3) aL4 See AL2 ÄÖT Disconnect unit from power supply. Take out ST4 from logic board K018. Check resistor (ST 4/1 - ST 4/2) by means of ohmmeter: Position control knob R (kohm) 0 0...0.1 5 4.1 ... 4.3 4 6.3.. .6.5 If wrong, adjust potentiometer or replace resistor incl. Potentiometer A02 See A01 A03 See A01 ATI Disconnect unit from power supply. Take out ST7 from logic board K018. Check resistor (ST 7/1 - ST 7/2) by means of ohmmeter: FLAT WOK Temperature Vitrocerame R (Ohm) Temperature Induction coil R (Ohm) 25° C / 80°F 980.... 1000 25°C/ 80°F 50 - 100 100° C / 210°F 1240.... 1280 180°C/355°F 3500 - 4500 150° C/ 300°F 1410 .... 1450 200°C/ 390°F ....1570 .1610 When out of the range, replace coil including temperature sensing element AF1 Switch off and remove fan. Clean it. AF2 Connect sign „ventiO“ (ST 1/10) with GND (ST 1/4) Fan must work. If not, fan is defective. Replace it. Otherwise logic board must be defective. Replace. 8 see “sign connector ST1" 8 Exchange of spare parts CAUTION All spare parts and accessories may only be changed by authorized personnel CAUTION In order to guarantee safety use only genuine OEM spare parts and accessories from Garland. Warranty is void if other • components are used no liability is accepted. CAUTION The electrical supply must be disconnected. (1-Phase, 3-Phases) Turn the induction unit over Remove screws Turn induction unit back in normal position Lift cover, turn away at the right side, put it to the right side Remove spool carrier: remove 2 stop nuts at the left Remove M4 screws Remove screws A1 and A2 Turn away spool carrier at the left Power board K016, K031 (1 Phase, 3 Phases) Removing the power board: • Disconnect all connectors on the power board: ST1 • Disconnect all clamped joints on the power board: 1 Phase: LI, N, PE, 1,2,3,4,7,8, 3 Phases: L1, L2, L3, PE, 1,2,3,4,5,6,7.8. • Disconnect ST5 on logic board K018 • Remove all soldered joints • Remove pin M4 and screw M4 in the corner of the print • Remove the connection to the transistor module, 3 screws M5x12 • Remove the rectifier, 5 screws M4x16 (3 Phases) or 4 screws M4x16 (1 Phase) Pay attention to the distance bolts and the plain washers: bolt head/spring washer/spring washer/ plain washer/ distance bolt (range the two spring washers together) • Remove power board Assembly of the power board • Put the power print on the bolts. Pay attention to the connectors J16, J17, J18, J19: The four wires of the transistor module must be connected through the wholes of the power board. Schrauben M4 (Vo...
