3.2 EXPLANATION OF CONTROL
SYSTEM

The E87 Prover has a power On/Off switch on
the control panel and isolates power to the
humidity and heating fan and light circuits
when switched Off. When switched On the
switch will illuminate to indicate that the unit is
On and operational. The air circulation fan is
On continuously on all E87 models when the
power switch is in an On position.

The proofing system operates on all models,
controls air temperature and humidity levels
by way of an air heating element controlled by
a mechanical bulb and capillary thermostat
and a water tank heating element controlled
by a mechanical bulb and capillary
thermostat.

The air heating element is positioned in the
bottom of the air circulation ducting inside the
cabinet and is directly controlled by the
user-adjustable thermostat mounted to the
control panel. The thermostat sensing bulb is
mounted inside the cabinet to control the
cabinet air temperature to the control panel
setting. An indicator light on the control panel
above this thermostat will illuminate when the
thermostat has the air heating element
operating and will cycling Off with the
thermostat to indicate when the temperature
reaches set point.

The water tank heating element controlled by
the humidity level thermostat mounted to the
control panel is used to heat the water tank
water and maintain water tank temperature
between 50°C (122°F) and 80°C (176°F).
This water tank temperature is controlled by
the humidity level thermostat setting between
the adjustments of low and high humidity.
The evaporation rate of the water in the water
tank dependent on its temperature, provides
humidity into the cabinet and accordingly the
setting of the humidity thermostat controls the
rate of evaporation and therefore the humidity
level in the cabinet.

An indicator light on the control panel above
the humidity dial illuminates when the water
tank element is On, and cycles Off when the
thermostat switches the heating element Off
to provide an indication of the humidity
control. The sensing bulb of the humidity
thermostat is mounted directly on the water
tank heating element which are both

immersed in the water tank. Should the water
tank level drop below the heating element the
humidity thermostat will cycle Off due to the
sensing bulb reacting to the radiated heat off
the heating element and will prevent the
humidity water tank heating element burning
out through excessive temperature.

E87 models require the operator to manually
fill the water tank and maintain the water tank
level as the water evaporates through
operation.

With all E87 models butter based products
such as croissants and danish pastries should
have the cabinet proofing temperature set
around 25°C (77°F) as higher proofing
temperatures will cause the butter to melt out
of the product, and for yeast based doughs
and breads the proofing temperature should
be set higher at around 40°C (105°F) in order
to activate the yeast in these products.

On all models the air circulation fan mounted
at the top of the air delivery ducting ensures
that the temperature and humidity throughout
the cabinet is even by creating a low velocity
air circulation system throughout the prover
cabinet. This system overcomes the natural
occurrence of hot air rising and therefore
higher humidity and temperature in the upper
positions of the cabinet as found with proofing
units without forced air circulation.

The user-adjustable thermostat and humidity
controls are required to allow adjustment of
cabinet temperature and humidity levels for
the variations of temperature and humidity
that different product types require.

Two cabinet illumination lights are provided in
the E87 models and these 15 watt each
incandescent filament lamps are On
whenever the control panel power switch is
switched on.

To prevent the formation of condensation on
the aluminium frame around the front of the
cabinet and to assist in minimising the
condensation occurring on the door frame and
door glass inner face a resistance wire
heating element is fitted into the cabinet
aluminium extrusion frame. This heating wire
is on whenever the power switch is switched
on and will heat the aluminium frame to a
warm-to-touch temperature.

6.1.3 FAN DOESN’T OPERATE
Fan motor faulty

Check the supply voltage across the motor
terminals. If there is no voltage then check
the electrical connections of supply wiring.

If voltage is correct then check the oven fan
for free rotation. Remove any obstruction.

If fan is free to spin and the voltage supply is
correct, then the motor is faulty—replace.

6.1.4 NO HEAT
Thermostat faulty

With cold prover, set thermostat to 40°C /
105°F. Check power to terminal 1 of top
thermostat. If there is no power then check
