Problem Remedy
Problems with checking
the working order: the
cooker power does not
shut down
• Retry with the same cooker plate and ensure that the
plate is set on highest power level.
• With an induction cooker use a suitable dish so that the
cooker is consuming power.
• Check all wiring of the Power control unit Ⓒ.
Cooker cannot be
turned on after pressing
the OK button ❸.
See user manual chapters 3.2 or 3.3. If the problem persists,
the appliance might be faulty. Press the OK button ❸to
ind out the problem type by the indicator light ❹:
Indicator light ❹blinks blue:
• Blinks once: Problem with wireless connection.
• Blinks twice: Problem with power control unit Ⓒ.
• Blinks three times: Power control unit Ⓒover-heating.

• Blinks once: Problem with sensors ❻.
• Blinks twice: Problem with sensor unit Ⓐ
• Blinks three times: Faulty installation position of the
sensor unit Ⓐ
Faulty installation
position of the sensor
unit Ⓐ.
Sensor unit Ⓐ will automatically recognize its installation
position during the irst time the cooker is used for
cooking. After the auto-recognition is completed, the
stove guard will prevent the use of cooker and oven if
the sensor unit Ⓐis removed from its original installation
position. To enable use of the cooker, place the sensor
unit Ⓐ back to the mounting bracket Ⓑ. If the problem
persists, the auto-recognition might not have been
successful. Ensure the correct position of the sensor
unit Ⓐ(see installation step 2/2) and manually reconnect
the wireless connection according to the installation
manual chapter 4.2. The fault should be then corrected
automatically in two minutes.
The wireless connection
is not working.
Go into the Manual adjustment mode and set up the
wireless connection manually, see chapter 4.
The sensor unit Ⓐis
not responding to any
button and none of the
indicator lights are lit.
Ensure that the batteries are not empty. Check the
correct position of the batteries marked on the bottom
of the battery case.
The appliance turns
o the power from
the cooker, but the
power comes back on
immediately.
Make sure that the power control unit Ⓒis connected
correctly – in other words, the cooker is connected to
the OUT cable.

5. Optional features
5.1 AUX-connection (optional)
Safera PCU6.3 and PCU6.1 power control units Ⓒ are equipped with two auxiliary out-
put signals AUX1 and AUX2 compatible with most automation and security systems.
They can be used to send real-time status information of the stove guard.
5.1.1 Electrical speciications
• Optoisolated and potential-free
AUX-outputs: no galvanic connec-
tion between the Safera system and
the automation system.
• When the AUX outputs are active
(ON), the optoisolator’s output tran-
sistors will be held in conducting
mode, thus enabling current low
from IN to OUT. This connection can
be used exactly as a relay’s contact,
however the direction and amount
of the current low must be con-
trolled as speciied below. If neces-
sary, the output states can also be
inversed (see chapter 5.1.6).
• Maximum IN-OUT voltage is 24 VDC.
• Maximum IN-OUT current is 10 mA.
• Only DC voltage between IN-OUT,
no AC is permitted!
5.1.2 Coupling AUX-wire to PCU6.3
and PCU6.1
Connect AUX-
wire to the
screw terminal.
Route the AUX-
wire through
the strain relief.
Mount the cover of the power
control unit Ⓒwith the screws and
ensure that the AUX-wire is properly
placed on the strain relief.

5.1.3 Example connection of one AUX-output
In this case the home automation system’s logic input is pulled to ground potential
when the AUX-output signal is active. Note that the maximum current pass in the
optocoupler is 10 mA!
The diagram illustrates the connection of one AUX channel. AUX1 and AUX2 are simi-
lar.
ѧHINT
Most building automation systems are equipped with inputs that are designed in a
way that they do not need the pull-up resistors. One example of this kind of input
is a 2-terminal input designed for connecting between relay contacts (potential
free connection). In this kind of situation the AUX can usually be wired directly to
the automation system. The only thing that must be observed is the current low
direction (IN >OUT) and that the current passing through must be limited to less
than 10 mA by the automation system.
5.1.4 AUX-signal logic interpretation
The AUX-signals can be interpreted in many ways:
• Simple ON/OFF information for any type of alarm (heat, ire or water leak). This
can be read directly from AUX1 output.
• Simple ON/OFF information for cooking activity. This can be read directly from
AUX2 output.
• Simple ON/OFF information for a fault condition. This can be read directly when
both AUX1 and AUX2 are connected in series to the same line.
• Four-state output according to the table below. This can be used by reading both
AUX1 and AUX2 separately into the automation system and using internal logic
to decide the state.

This state will activate immediately when the stove is powered.
It will turn o in roughly 1 to 30 minutes after the cooking has
stopped, depending on how hot or powerful the cooking has
been. This delay serves two purposes:
1) the signal can be used for optimally controlling the cooker hood
fan or a kitchen extractor fan, and
2) the signal OFF->ON steps can be used for counting the amount
of cooking processes.

Dangerous situation detected: cooking hazard, timeout or
extreme stove temperaure has caused a power cuto from the
cooker. Also, water leakage alarm will trigger this state. This state
will be cleared only when the user presses the OK-button of the
Sensor Unit.
ON ON Service needed
In most cases, power to the cooker has been cut o until the fault
is resolved. This includes all critical Sensor Unit or Power Control
Unit faults. Press the OK-button of the Sensor Unit to see the exact
cause for the fault.
5.1.6 Inversed AUX-mode
Inversed AUX-mode = all ON signals indicated as OFF and vice versa in the table above.
Inversed signal mode can be useful for example when the maximum reliability for
fault detection is needed: if the wires are broken, or all electricity is cut o, the out-
put will be the same in as the AUX1:OFF & AUX2:OFF “fault condition”.
⚐ATTENTION
The inversed mode will create a larger load for the connected system, because
both signals will be ON most of the time. For example, this may be harder for bat-
tery operated external clients. However, it will not aect the Safera system's own
battery life.

5.2 Water leakage sensor (optional)
Stove Guard can be equipped with max.
four Safera water leakage sensors. The
sensors are placed in the typical leak-
age areas, e.g. under the dishwasher or
sink.
Attach the sensors Ⓕin place.
Attach the plug Ⓖ of the leakage
sensor to the power control unit
Ⓗ.
If there is an extra sensor, its plug
Ⓖis connected to the connector
Ⓘof the previous sensor.
Check the operation of the fur-
thest sensor Ⓕby placing a damp
paper towel against it for 15 sec-
onds. When the water is detected, the
sensor unit Ⓐgives a sound signal and
indicator light will blink in blue.
Reset the leakage alarm by press-
ing the OK button ❸. Clean and
dry the sensor.
ѧHINT
If the sensor is left wet, the appliance
will give another alarm 8 hours after
signing o the previous one.
