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
preconfigured.
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.

* In the case of installation beyond the standard height of 55 ... 65 cm, the alarm limit must be
adjusted accordingly (see Setting alarm limit).

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 off 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 confirmation.
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 (figure 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.
