Device description
3.1.5

Operating principle

A pair of devices is necessary for establishing a data transmission path. To prevent the devices from mutu-
ally interfering with one another during data transmission, they use different frequencies.
• one device with frequency F3
Part designation: DDLS 538 xxx.3 S2 xx
Designation on the name plate: Frequency F3
• one device with frequency F4
Part designation: DDLS 538 xxx.4 S2 xx
Designation on the name plate: Frequency F4
NOTICE
Installation for devices with an operating range of 200 m.
Ä Always install the Frequency F4 device as stationary device for devices with an operating
range of 200 m (DDLS 538 200...).

The received signal level (SIGNAL QUALITY) is measured on both devices. If the received signal level
drops below a certain value (SIGNAL QUALITY indicator shows only red and orange), the intensity warning
is activated.
The intensity warning is applied on switching output IO1 of the POWER connection.
