Electrical installation

5.4 Preparations for electrical installation

5.4.1 Requirements for the host interface

The host interface of the CLV can be operated as an RS 422/485 or an RS 232 interface.

Table 5-7

shows the recommended maximum cable lengths as a function of the selected

data transfer rate.

To prevent interference, do not lay the cables parallel with power supply and motor

cables over long distances, e. g. in cable ducts.

5.4.2 Supply voltage

The CLV requires a supply voltage of 18 ... 30 V DC for operation without a heater and

24 V DC +20 %/–10 % for operation with a heater, to IEC 742 (functional extra-low

voltage). The power consumption of the individual types is as follows:

Power-up delay

The selected device number (default: 1) affects the power-up delay of the device. This is

useful if a large number of CLVs (e. g. in the SICK network) are to be supplied from one

power source.

Table 5-9

contains a list of the available intervals.

Tip

The device number can be selected on the D

tab in the "CLV-Setup"

program.
