3.2 EXPLANATION OF CONTROL
SYSTEM

The E89M/MS Prover/Holding Cabinets feature
operator controls and an electrical circuit for
which a direct understanding of their operation is
required before carrying out any service work or
fault repair work. The control device functions
and electrical circuit are explained as follows:

Function Switch

A rotary switch on the control panel of these
models functions as the power On/Off switch of
the unit by isolating the Line 1 phase supply.
This switch is a 3 position, 4 pole, multi-function
switch which in the Off position opens circuits all
poles and isolates power from all control and
heating systems. The switch should operate as
illustrated below.

P1 – No function / not used.
P2 – Additional air heating element.
P3 – Humidity control thermostat.
(Auto-fill models only - water solenoid, float
switch, solenoid relay)
P4 – Air heating thermostat, cabinet lights, air
circulation fan motor and control panel
power indicator.

P1

H

P2

P

P

P4

The air circulation fan, cabinet lights and control
panel power indicator are On continuously on all
E89 models when the function switch is in either
of the PROOF or HOLD positions. 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.

Proof Mode

In the ‘Proof’ position the function switch poles
P1, P3 and P4 are closed, supplying power to the
dry heat circuit, humidity circuit, cabinet lights and
fan.

Figure 3.2.1

The proofing system controls air temperature and
humidity levels by way of an air heating element
and a water tank heating element.

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
cycle Off with the thermostat to indicate when the
temperature reaches set point. The main
thermostat is adjustable up to 85°C (185°F).

The humidity thermostat mounted on the control
panel controls the water tank heating element,
which in turn maintains the water temperature
between 20°C (68°F) and 85°C (185°F). The
evaporation of the water provides the cabinet
humidity. The setting of the humidity thermostat
(between 1 - 8) controls the rate of water
evaporation and therefore the level of humidity 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 to the water tank heating element, which
is 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.

Hold Mode

When the function switch is turned to the ‘Hold’
position the function switch pole P3 opens to turn
off the humidity control circuit, and pole P2 closes
to connect an additional air heating element to
the air temperature thermostat circuit. In this
mode the air temperature thermostat operates as
it does in the proofing mode, however, in this
case there is an additional air heating element
switched On and Off to provide extra heating
power in this mode. The additional air heating
element is also mounted in the air circulation
ducting.

E89M/MS Prover/Holding Cabinets are provided
with a thermometer dial on the control panel to

Revision 1/F3608

-10-

provide an indication of the cabinet temperature.
The sensing bulb of this thermometer dial is
mounted next to the sensing bulb of the main
thermostat inside the cabinet.

Auto water fill (option)

E89 Auto-Water fill models provide for a mains
cold water supply connection for automatic water
tank filling and level control. Non Auto-Water fill
models require the operator to manually fill the
water tank and maintain the water tank level as
the water evaporates through operation.

On Auto-Water fill models an electric solenoid
valve, float switch and relay maintain the water
level in the humidity tank. The float switch is
mounted at the rear of the water tank, and when
the water is below the full level it open circuits,
removing power from the coil. When de­energised, the relay removes power from the
humidity thermostat circuit (therefore switching off
the humidity element), and switches power to the
water solenoid. As the water level reaches the
full level position the float switch contact will
close, re-energising the water solenoid relay,
thereby closing the water solenoid valve and
providing power back to the humidity thermostat.
Accordingly this system will automatically
maintain a full water tank whenever the function
switch is in the “PROOF” position and the mains
water supply is turned on.

Ensuring that the function switch is in the Off
position is necessary whenever removing the
water tank for cleaning as when the water tank is
removed the float switch drops and the water
solenoid valve will open (if the unit is on).
Therefore as a precaution the mains water supply
should also be turned Off whenever removing the
water tank.

element is faulty - replace.

To test element, disconnect terminals and check
resistance across element.

Resistances;

208 - 240V models 72 Ω ±3.6 Ω
110 - 120V models 20.5 Ω ±1 Ω

6.1.6 NO HUMIDITY CONTROL

Humidity thermostat faulty

Switch the prover on and set the humidity to ‘4’.
Check that the humidity thermostat cycles on /
off, and using a suitable probe measure the
temperature of the water in the trough. The water
temperature should be 50°C/120°F ± 10%. If the
temperature continues to rise above this then the
humidity thermostat is faulty - replace.

Water level float switch faulty

To check correct operation of float switch
remove the float switch wire connections from
terminal 8 and terminal 5 on relay. With full water
tank (float switch in raised position) float switch
should be closed circuit. With empty water tank
(float switch in lower position) float switch should
be open circuit. If not, float switch is faulty—
replace.

Solenoid relay faulty

E89 auto-fill models are fitted with a 2 pole
change over relay, with its coil controlled by the
float switch located in the water through / tank.
When the water level is below the full position the
coil is not energised, allowing the relay to supply
power to the water solenoid. In this position the
relay should have no power at terminals 3,4 and
8, but power at terminals 1,2,5, and 6,

6.1.7 NO HEATING / HUMIDITY INDICATOR

Indicator faulty

Check voltage across indicator terminals with
controls on and appropriate thermostat turned on
fully. If the voltage is correct and indicator is not
illuminated then the indicator is faulty - replace. If
there is no voltage then check wiring.

6.1.8 AUTOFILL NOT FILLING OR OVER
FLOWING (AUTOFILL MODELS ONLY)

Water solenoid faulty

Empty water tank so float switch is in lowest
position. With power ON check voltage across
water solenoid coil terminals. If voltage is correct
(refer electrical rating plate) but solenoid is not
operating, disconnect electrical supply and
remove wire connections from solenoid. Check
solenoid coil windings resistance.

Correct coil resistance:
208 - 240 volt models 3650 Ω
110 - 120 volt models 1100 Ω

NOTE:

If open circuit/high resistance, then the

coil is faulty– replace.

If coil is correct, rewire and listen for audible
solenoid click when power is supplied. If solenoid
can be heard functioning and water supply is
turned on but no water is entering tank, remove
water solenoid and fittings and check for
blockages.

Figure 6.1.3

When the water level reaches the full position the
float switch supply’s power to the relay coil, which
in turn cuts power to the water solenoid and
supply’s power to the humidity tank. In this
position the relay should have no power at
terminals 1 and 2, but power at terminals 3,4,5,6,
and 8.
