the relay releases and the LED goes ON. The relay remains released until the
sensor is deactivated.
CB32 with OFF-delay output:
The time measurement starts and the LED flashes when power supply is
applied to the sensor. When the set time has expired, the relay operates (con-
nection between black and yellow wires) and the LED goes OFF. When the
sensor is activated, the relay releases and the LED goes ON. As soon as the
sensor is deactivated, the measurement of the set time starts.
The CB32 sensor family has to be non-flush mounted (approx. 10 mm). Keep
the grey front of the sensor free.

Hazardous location
NB: The relay will be activated when the sensor is not activated.
Establish an effective ground connection between the sensor housing and the
installation equipment in which the sensor is mounted.
If a longer cable is required, an equipotential bonding of the cable longer than
the 2000mm (standard for the CB32 series) has to be made, e.g. by drawing
the cable in a grounded metal pipe.
