3.2 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

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. The oven
lamps are on with the oven door open and
closed.

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

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
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 door switch, mechanical
micro-switch below oven opening, which breaks
the power supply to the oven fan, temperature,
and steam control circuits when the door is
opened. Additionally, opening the oven door will
remove power from the Bake Timer buzzer and
indicator, and the vent position indicator neon.

Revision 5/F3512

-11-

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 in this
manual). 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 4pole/8pole configuration is used.

Fan / Motor Direction

The direction change is made by swapping two
phases to the motor through the motor contactors
C2 and C3. In one direction L1, L2, and L3 are
switched through motor contactor C2 with motor
contactor C3 open. In the alternate direction,
motor contactor C2 is open, and C3 is closed. L1
and L2 are reversed on the C3 contactor
connections. Motor contactors C2 and C3 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.

The direction control timing is provided from 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.

Revision 5/F3512

-12-

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 T3 dwell timer will
then switch power through to the other motor
direction contactor (refer previous) after the
preset 10 second 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.

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.

Motor Protection

Refer Circuit Protection at start of section.

Steam System

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

Revision 5/F3512

-13-

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.

Summary of Components

The electrical switchgear (not user controls)

6.4.5 FAN & STEAM TIMER OPERATION /

ADJUSTMENT

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 6.4.5 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)
