3.3 EXPLANATION OF CONTROL SYSTEM
The E35 Turbofan convection oven features multi-function operator controls, and a combined fan motor and steam control system.
A correct understanding of their operation is required before carrying out any service or fault repair work. The control device functions are explained as follows:
Circuit Protection
All models are fitted with a 3 pole circuit breaker, from which a control circuit is taken from L1 circuit breaker, and this control circuit is fitted with a 6A circuit breaker. The 3 pole main circuit breakers are rated 25A/pole for 3P+N+E/GND and 1P+N+E/GND supply models, and 40A/pole for 3P+E/GND (no neutral) models. These pro­vide control circuit protection via the 6A circuit breaker, and load circuit protection via the 3 pole circuit breakers.
Additionally, the 3 pole circuit breaker is mechanically connected to a Shunt Trip breaker, which in the event of the oven fan motor overheating will trip the 3 pole circuit breakers to isolate power from the unit. The Shunt Trip is directly connected to thermal limit switches in the motor windings, and the supply Neutral (or L3 on 3 phase, no neutral models). A supply from the 6A control circuit breaker is connected to the motor thermal switches. Should any of the motor windings overheat, the thermal switches close and supply power to the Shunt Trip, which in turn trips (triggers) and mechanically trips the 3 pole circuit breaker.
Accordingly, causes of circuit breakers tripping can be ascertained with the above knowledge, and this is covered in more detail in the Fault Diagnosis section.
Power ‘On’ / ‘Off’
A Power switch on the control panel isolates power to the operator controls of the oven. With the power switch OFF all functions of the oven are inoperable.
An integral cooling fan, behind the control panel used to keep the electrical controls of the oven cool, is on continuously whenever the power supply to the oven is on. Switching the oven control panel Power switch off will leave the cooling fan running.
With the Power switch ON (illuminated neon indicator), power is supplied to all operator controls.
Oven Lamps
Up to Lot No. 0817999.
The two oven lamps (12 volt halogen) are on whenever the Power switch is on. The oven lamps are supplied with 12 volts from an electronic lamp transformer fitted on the oven’s control switchgear assembly.
From Lot No. 0818001.
The two oven lamps (208 / 240 volt halogen) are on whenever the Power switch is on. The oven lamps are supplied with mains voltage.
Bake Timer
The 60 minute bake timer is a mechanical timer and can therefore be operated with the oven’s power ON or OFF. However only with the oven’s power switch On and the oven door closed will the timer turn on the time-up buzzer and time-up indicator neon on the control panel. The buzzer and time-up indicator provide indication that the time setting has run down to zero and at this point will remain on continuously until the 60 minute timer has been manually set back to the Off (vertical) position. The 60 minute timer does not control any other part of the oven’s operating system as the timer is independent of the temperature control, heating, fan, or steam system.
Oven Vent
Up to Lot No. 0817999.
The oven vent is a manual operation by way of the Vent knob on the control panel.
The vent knob directly rotates the vent shaft through 90 degrees to open and close the vent. The vent shaft passes through a rotary switch mounted behind the control panel and this switch is used to switch ‘On’ or ‘Off’ the vent indicating neon. In the vent ‘Open’ position, the indicator is illuminated. The oven vent restricts venting of the oven when in the closed position, however the vent flap is fitted with a spring loaded over­pressure flap which relieves excess pressure created during oven steaming. This avoids steam pressure escaping out of door seals etc, if the oven is steamed with the vent closed. The spring pressure on the over-pressure vent flap ensures that only excess steam is lost out of the vent.

however the vent flap is fitted with a spring loaded over-pressure flap which relieves excess pressure created during oven steaming. This avoids steam pressure escaping out of door seals etc, if the oven is steamed with the vent closed. The spring pressure on the over-pressure vent flap ensures that only excess steam is lost out of the vent.
Door Switch
The oven has a mechanical door, micro-switch located below the oven opening, which breaks the power supply to the oven fan and temperature control circuits when the door is opened. Additionally, opening the oven door will remove power from the Bake Timer buzzer and indicator. This allows only the oven lights to be operational if the oven door is opened.
Thermostat Control
Heating of the oven is controlled by an electronic thermostat control, comprising of a potentiometer dial and knob on the control panel, a temperature sensing probe (thermistor type) in the oven chamber, and the thermostat control board behind the control panel. Power to the electronic thermostat is supplied through an over-temperature/hi limit thermostat. Accordingly a failure of the electronic thermostat control causing a temperature over-run will result in the over-temperature thermostat switching and removing power from the heating control circuit. The over-temperature thermostat is able to be manually reset, however a serviceman is required to perform this function, as removal of the R/H service panel is required to access this safety protection device.
The electronic thermostat when set to a temperature will illuminate the heating neon indicator on the control panel whenever the oven heating elements are on. When the indicator neon goes out, the oven is up to the set temperature.
Heating / Elements
The electronic thermostat when requiring heating of the oven, switches power to the heating contactor (referred to as C1 contactor on models prior to Lot no 0817999, and C3 on models from Lot no 0818001).
The heating contactor closes to supply power through to the heating elements in the oven. In all ovens all 3 poles of the contactor are used to supply L1, L2, and L3 phase circuits to the 3 heating elements on each side of the oven fan motor.
On 3 Phase + Neutral supply models, all 6 elements are looped to neutral, and the 3 Phase power to the elements is to each set of three elements in parallel connection. Hence each of the elements is supplied with the Phase to Neutral voltage.
On 3 Phase supply models (no neutral), the set of three elements each of the fan motor are connected in Delta configuration, which each element being supplied the Phase to Phase voltage.
On 1 Phase + Neutral supply models, all 6 elements are looped to neutral, and the 1 Phase power to the elements is split into three poles at the main circuit breakers on the oven, then feed through the three poles of the heating contactor, from where each pole is connected to two of the six elements in parallel. Hence each of the elements is supplied with the Phase to Neutral voltage.
The heating elements are rated at 2000 Watts each, therefore providing a total of 12000 Watts or 12kW of heating.
In some cases special heating kilowatts may be supplied to special request, so always check rating plate information on the unit if in doubt.
The heating contactor cycles ON / OFF as controlled by the thermostat to maintain set oven temperature.
Fan / Motor
The E35 Turbofan ovens use a dual speed, bi-directional oven fan circulation system, in order to provide even heat distribution through the oven, and fan speed control to suit different product types.
To provide both dual fan speed and bi-direction, a motor of 4 pole / 8 pole configuration is used.
Fan / Motor Direction
The direction change is made by swapping two phases to the motor through the motor contactors. On models to Lot no 0817999 these are referred to as C2 and C3 contactors. On models from Lot no 0818001 these are referred to as C1 and C2 contactors.
In one direction L1, L2, and L3 are switched through the first motor direction contactor with the second motor direction contactor open. In the alternate direction, the second contactor closes and the first contactor opens. L1 and L2 are reversed on the second contactor connections. The motor contactors are mechanically inter­locked (interlock fitted to rear of contactors) to prevent any switching overlap.

Motor direction change is automatic, and the duration of the direction cycle is factory set. Additionally, a dwell period between at each change of direction occurs to allow the motor to restart in the opposite direction only after the motor rotation has slowed down. This is necessary to avoid motor overheating due to the high current load that would be required to change direction instantaneously.
Each direction cycle is 90 seconds long, at the beginning of which is a preset 10 second dwell / delay. As the dwell is at the beginning of the cy­cle, the fan always has a 10 second start delay when the oven is first turned on, or when the door is closed after opening.
Up to Lot No. 0817999.
The direction control timing is provided by three electronic timers mounted below the motor contactors on the electrical switchgear panel of the oven. Timer T1 controls the direction cycle time, timer T3 controls the dwell for one direction and timer T5 controls the dwell for the opposite direction.
When the door is closed and power is ON, cycle timer T1 will switch power to dwell timer T3 for 90 seconds. Timer T3 will then switch power through to motor direction contactor C2 after the preset 10 second delay. The motor will then run for the remainder of the 90 second cycle.
At the completion of the 90 second cycle, cycle timer T1 will switch the power from T3 dwell timer to T5 dwell timer. This dwell timer will then switch power through to contactor C3 after the preset 10 s
econd delay, and the motor will run in the opposite direction for the remainder of that 90 second cycle. At the completion of that cycle the cycle timer T1 switches power back to the other dwell timer, and this continues until the oven door is opened, or the power is turned off.
From Lot No. 0818001.
The direction control timing is provided by a single Motor Direction Cam Timer mounted below the motor speed contactors C4, C5 and C6 on the electrical switchgear panel of the oven.
The circulation fan on the E35 oven reverses direction every 90 seconds for a 50Hz supply (every 75 seconds for 60Hz). Prior to a change of direction the fan motor is switched off for 10 seconds (8½ seconds for 60Hz) to allow the motor / fan to slow down. Cycling of the fan motor is controlled by a continuous cam timer with electric motor. The timer has two cams and switches which supply power alternately to one of two motor supply contactors, causing the motor to alternate direction. During the fan motor slow down periods, both cam switches are open and
power is not supplied to either of the motor supply contactors. When the oven door is opened or the power is switched off the cams will stop. When the oven door is closed or the power switched back on the cam timer will resume its cycle from the point where it stopped.
Fan / Motor Speed
For HI speed operation the motor is run as a 4 pole motor. (1420 rpm 50Hz / 1750 rpm / 60Hz) For LO speed operation the motor is run as an 8 pole motor. (715 rpm 50Hz/850 rpm / 60Hz)
Selection of the pole configuration for run speed is made though the motor contactors C4, C5 and C6.
In HI speed setting the motor contactors C4 and C6 close, C4 switching power to the motor on the 4 pole connection leads, and C6 binding 4 of the 8 motor poles to allow motor to run as a 4 pole motor.
In LO speed setting the motor contactor C5 closes to switch power to the motor on the 8 pole connections leads, with contactors C4 and C6 remaining open.
Motor contactors C5 and C6 are mechanically interlocked (interlock fitted to rear of contactors) to prevent any switching overlap between LO and HI speed changes.
The motor speed control is by manual operation of the Fan Speed switch on the control panel. This rotary switch simply supplies power to either motor contactors C4 and C6 for HI speed, or C5 for LO speed. The contactors stay closed in the selected setting unless the oven door is opened. Closing the oven door allows the contactors to switch on again.
Fan / Motor - Single Phase Models
The operation of the fan motor on single phase E35 models is the same as other three phase models for two speed and bi-direction operation, except for the electrical circuit required.
On single phase models the same motor is used as on three phase models, but with capacitors in the motor circuit to create an artificial phase lag, that is normally part of the three phase supply on three phase models. Use of the three phase motor is required to retain the bi-direction operation.
On single phase models the L1 supply to the motor connects to the normal L1 connection of the motor, and the Neutral supply connects to the normal L2 (as connected on three phase models) connection of the motor. A capacitor is then connected to the normal L3 (as connected on the three phase models) connection of the motor, and

this capacitor is supplied power from the L1/ Phase supply. This capacitor is referred to as the Run capacitor as it is permanently in the circuit during motor operation. Each motor on single phase models has two run capacitors, one for the LO speed operation (lower capacitance) and one for the HI speed operation (higher capacitance). Each Run capacitor is only used when the motor is running at that speed setting.
Additionally a Start capacitor is also fitted on single phase models, and is used for starting the motor rotation at the beginning of each direction change when in HI speed setting only. This capacitor is switched on for approximately 7 seconds only at the beginning of each motor start up, with a contactor C7 switching the Start capacitor on and off, and with a timer T6 controlling the timing of the contactor C7.
Fan direction change in single phase models is still controlled by motor contactors C2 and C3. However unlike three phase models where C2 and C3 swap phases over to change motor start rotation / direction, single phase models use C2 and C3 to switch the run capacitor form the L1 supply to the Neutral supply for direction change.
Control of the motor cycle timing and dwell timing is the same as three phase models.

Steam System
Up to Lot No. 0817999.
The E35 Turbofan ovens feature an automatically timed oven chamber steaming system, that allows operators to inject a 10 second period of steam into the oven at any stage. The steam is generated when a solenoid valve opens and supplies mains water to a calibrated wide spray angle nozzle in the oven that discharges the wa­ter as a fine spray into the oven fan. The fine spray at a wide angle is then immediately thrown by the fan circulation across the oven heating elements either side of the fan. The fine spray instantaneously turns to steam on the hot elements, which is supported by the hot air of the oven also turning the water droplets into steam.
The steam is initiated by depressing the Steam switch on the control panel. When depressed the steam switch provides power one of two Steam timers which are preset to 10 seconds steam cycle duration. These Steam timers are T2 and T4.
T2 is associated with fan dwell timer T3 and is used when steam is required during the fan direction cycle that uses the T3 dwell timer.
T4 is associated with fan dwell timer T5 and is used when steam is required during the fan direction cycle that uses the T5 dwell timer.
This ensures that steam can be used in either fan direction cycle, and additionally allows the fan to be turned on as soon as steam is activated, even if the fan was in a direction change dwell. Ensuring that the fan is running when steam is required is necessary to atomise the water droplets by the mechanical action of the fan, and by the fan throwing the water across the elements.
The Steam switch on the control panel only needs to be depressed momentarily as the duration of the steam injection is automatically timed by the steam timers. The Steam switch will illuminate for the duration of the steam injection to provide a visual confirmation of the steaming process. The light in the steam switch is independent of the switch contacts and is powered by the electrical circuit to the water solenoid valve. Therefore the switch is illuminated for as long as the water solenoid is open: 10 seconds.
Steam System
From Lot No. 0818001.
The E35 Turbofan ovens feature a manually operated oven chamber steaming system, that allows operators to inject a shot of steam into the oven at any stage. The steam is generated when a solenoid valve opens and supplies mains water to a calibrated wide spray angle nozzle in the oven that discharges the water as a fine spray into the oven fan. The fine spray at a wide angle is then immediately thrown by the fan circulation across the oven heating elements either side of the fan. The fine spray instantaneously turns to steam on the hot elements, which is supported by the hot air of the oven also turning the water droplets into steam.
The steam is initiated by depressing the Steam switch on the control panel. When depressed, the steam switch provides power to the water solenoid. Pressing the Steam switch for one second will provide one second of steam, pressing the steam switch for 5 seconds will provide 5 seconds of steam.
The Steam switch will not illuminate as with pre-Lot No. 0818001 Ovens.

6.4.7 FAN & STEAM TIMER OPERATION / ADJUSTMENT (Up to Lot No.0817099)
All the timers have a dial on the front that adjusts the time the timer switches for when control energised. All the timers have an LED on the front that flashes when the timer is switched.
T1 Fan Cycle Timer
This timer switches power between the clockwise and anti-clockwise fan direction circuits, the time set is the duration on each fan direction.
Factory set to 1
1
/2 minute.
Refer to Appendix C for timer settings.
T2 & T4 Steam Timers (2)
These should be set the same and determine the duration of the steam, one for clockwise fan circuit and one for anti-clockwise fan circuit. If the steam cycle is too long water will condense on the product and oven chamber, and oven may cool too much - it is usually better to have multiple cycles than a long cycle.
Factory set to 10 seconds.
Refer to Appendix C for timer settings.
T3 & T5 Dwell Timers (2)
Once again these should be set the same, this is the delay time between fan directions and after steaming, when no power is applied to the fan motor. One is for the clockwise fan circuit and one is for the anti-clockwise fan circuit.
Factory set to 10 seconds.
Refer to Appendix C for timer settings.
Figure 6.4.7 shows the function of the timers on a time line. The grey areas are when a timer is switched (LED flashing) or where fan is rotating / steam injecting. The dark lines show when the steam button has been pressed, the first is most common while the next two show the effect of steaming at the beginning or end of a direction cycle. Priority (power flow) is top to bottom on the chart (cycle timer effects all others)
