According to the standard EN 50615 the device is able to distinguish between the normal use of a cooker/hob and a hazard. Nevertheless, during normal use of the cooker/ hob attention hast to be paid to hazards as the device cannot detect all possible situations. The sensor unit monitors the temperature in- crease and use of the cooker/hob. If a potential hazard is determined, a pre-alarm is triggered if necessary. If this is not acknowledged by the user, the power control unit switches o󰀨 the power supply to the cooker/hob after 15 sec- onds. If the critical situation on the cooker has been remedied, the pre-alarm can be cancelled or the power supply to the cooker can be reacti- vated by pressing the operation button (3) or by tapping at any position on the sensor unit of the pre-alarm, if activated.

Table 2: Meaning of the battery status LED To avoid false alarms, we recommend: - wiping the sensor unit with a damp cloth and mild cleaning agent periodically - leaving the sensor unit in its position and avoiding unintended movement

4.1 Setting alarm limit

The default setting is to be used for the initial setup. The alarm limit can be adjusted to the respective environment in the kitchen to ensure optimum functioning of the device. The alarm limit can be adjusted if false alarms occur frequently (see Manual Settings). To do this, set the alarm limit two levels higher or lower (maximum) as recommendedz

4.2 Automatic child lock

The automatic child lock is deactivated by default. Switching on child lock Keep the operation button (1) pressed for 5 seconds. Two high acoustic signals (●●) sound and the status LED ashes green twice. Child lock is switched on. The automatic child protection is activated about 10 ... 60 minutes after nishing cooking, in order to prevent the cooker/hob from being switched on accidentally. Switching o󰀨 child lock Keep the operation button (1) pressed for 5 seconds. A low acoustic signal (●) sounds and the status LED ashes red. Child protection is switched o󰀨. Switching on cooker with activated child lock Press operation button (3). Switch on cooker/hob. If the operation button (3) is not pressed rst, the automatic child lock switches o󰀨 the power supply of the cooker after 5 seconds.

4.3 Dangerous situations

If a potential hazard is determined, a pre-alarm is triggered if necessary. If this is not acknowl- edged by the user, the power control unit switches o󰀨 the power supply to the cooker/hob after 15 seconds. If the critical situation on the cooker has been remedied, the pre-alarm can be cancelled or the power supply to the cooker can be reactivated by pressing the operation button (3) or by tapping on the sensor unit (see 4.4) of the pre-alarm. Pre-alarm has tripped Closely examine the situation on the cooker. Press the operation button (3) if the situation on the cooker is OK. Pre-alarm has been acknowledged. The cooker is not switched-o󰀨. Switching o󰀨 the cooker If the pre-alarm is not acknowledged within 15 seconds, the power supply of the cooker is interrupted. If there is no danger or if the danger has been remedied, the power supply can be restored by pressing the operation button (3). Avoid dangerous situations in the further course of cooking. In the case of too frequent false alarms, manual commissioning must be carried out.

4.4 Alarm conrmation by tapping the sensor unit (optional)

The operation button (3) is pressed as standard to cancel the pre-alarm or to reconnect the power supply to the cooker. Alternatively, this can also be achieved simply by tapping the sensor unit. Activating/deactivating the tap function: Hold the operation buttons 1 and 3 for ap- prox. 5 seconds simultaneously until a signal tone sounds. The Status LED (5) of the sensor unit ash- es yellow 3x and then red 3x. The tap function is activated. OR: The Status LED (5) of the sensor unit ash- es yellow 3x and then blue 3x The tap function is deactivated.z

The cookguard functions can optionally be extended with up to four water leakage sensors. If the sensors come into contact with water, a water leakage alarm is triggered (Table 1). The status LED ashes blue slowly accompanied by an acoustic signal. Procedure with water leakage sensor: Press the operation button (3) to acknowl- edge the water leakage alarm. The acoustic signal and ashing status LED (5) went out. Switch o󰀨 power supply. Remove the cause of the water leakage. Clean and dry water leakage sensor(s) with a clean cloth. Switch on power supply again and perform functional test. If the water leakage sensor remains wet, it retriggers an alarm after 8 hours.

4.6 Potential-free contacts (optional)

The device has two potential-free contacts AUX1 and AUX2 (gure 6) e.g. that a KNX radio binary input can be connected to. In this way, for example, an alarm signal can be sent to the KNX bus. The alarm signal remains activated until the alarm (see Hazardous situation, water leakage) is acknowledged by pressing the button (3) on the sensor unit. The wiring of the potential-free contacts and their meaning is shown in table 3. In the normal mode of the AUX outputs, the contact between In and Out is closed when ON and opened when OFF. The AUX output signal can also be reversed. The reversed signal can, for example, be used to detect a cable breakage or if the power supply has been interrupted completely (see

Chapter 5.1 "Connect potential-free contacts")

In the inverted case, the contact between the In and Out terminals in the OFF state is closed and opened in the ON state. If a KNX radio binary input is used, the usage of reversing AUX signals may lead to a reduction of the battery service life of the radio binary input. The AUX outputs can be connected in four ways (Table 4). Option 1 is to be used for forwarding the alarm message. AUX1 AUX 2 System status OFF OFF No alarm message! Cooker switched o󰀨 or no hazardous situation OFF On Cooking activity is detected. This status is activated immediately after switching on the cooker. Depending on the intensity of the cooking, the signal is switched o󰀨 1 ... 30 min after nishing the cooking process. This delay time can be used to: - switch on e.g. an extractor hood or kitchen exhaust using the signal that is present. - perform an evaluation, how often cooking occurs, with the signal change from OFF → ON.z

AUX1 AUX 2 System status On OFF Alarm! A hazardous situation is detected and the cookguard switches o󰀨 the power supply in case of danger, timeout or overheating. The alarm state is also activated when the water leakage sensor has tripped; even though the power supply of the cooker/hob is not interrupted in this case. The alarm signal can only be deactivated by pressing the button (3) on the sensor unit. Water leakage sensor has tripped. The power supply to cooker is not inter- rupted. Leakage alarm is only switched o󰀨 after pressing operation button (3). On On Service! Fault on sensor, voltage interruption or empty battery detected and power supply to cooker is interrupted. The exact fault signal is displayed by pressing operation button (3) (see chapter 6.2 Troubleshooting).

Connect potential-free contacts The device is equipped with two potential-free outputs AUX1 and AUX2 (18). This allows forwarding of the state of the cookguard to binary inputs of the building automation system or other safety systems (for further information, see Section 4.5). The AUX outputs are optoinsulated and poten- tial-free. Due to the optocoupler, attention must be paid to the polarity of the scanning voltage of the binary input of the building automation sys- tem. The Out terminals must be connected to the earth or earth potential of the binary input. The scanning voltage between In and Out may be a maximum of 24 VDC and must be at least 3 V. The current between In and Out is to be limited to a maximum of 10 mA. Only DC voltage is permitted between the In and Out terminals. The device to be connected should already be precongured. Remove the break-out opening (11) on the housing base (Fig. 7). Connect potential-free output Pay attention to polarity! Clamp the cable in the cable routing slot. Sensor Unit - Selecting installation location The sensor unit can optionally be mounted on the wall above the cooker/hob or directly under the extractor hood (Figure 8). The sensor unit monitors the temperature and use of the cook- er/hob and switches o󰀨 the power supply in the event of an alarm. Remove mounting bracket (8) carefully from the sensor unit. Insert batteries into the sensor unit. Connection to the power control unit is established automatically. If radio connection is successful, the sensor unit emits two acoustic signals for conrmation. Fasten mounting bracket (8) again to the sensor unit. Remove any grease and dirt from the mount- ing surface using the cleaning pad supplied. Attach sensor unit using supplied adhesive stripes (gure 8) (optional: use supplied fastening material). Make sure that the sensor is aligned correct- ly. In case of cooker widths between 70 ... 90 cm, the alarm limit should be set one level lower as recommended in table 5. The sensor unit must be mounted in the mid- dle above the cooker/hob. max. 15 cm max. 15 cm
