7.1.2.2 RCSS Interface supply

The receiver has two safety outputs, RCSS1 and RCSS2. They shall be connected to the

machine safety circuit in such a way that either one of them can stop the machine indepen-

dently.

The current consumption on each RCSS feeding point is depending on the controlled devices

connected to the output, but shall not exceed 3 A. The fuse for each RCSS feeding point shall be

max10 AT, and of slow blow characteristic and high breaking capacity.

7.1.2.3 Digital Interface supply

Each feeding point supports four outputs. The current consumption on each feeding point is

depending on the controlled devices connected to the outputs, but shall not exceed 3A/output or

in all 4 A within the group. The fuse for each feeding point shall be max 10AT, and of slow blow

characteristic and high breaking capacity.

The following must be observed regarding the use of PWM/Digital interface as input and

output:

Avoid mixing inputs and outputs within one supply voltage feeding point. A feeding point is

marked by VDD_3 to VDD_8. See chapter “7.1.2 Connecting power supply”.

The reason is a possible internal cross connection from the inputs to the outputs. This may occur

if the supply to the feeding point is disconnected externally.

Should a mixture still be carried out the system integrator must perform and document a risk

analysis of the possible consequences.

7.1.2.4 Serial interface cabling

For the CAN and RS422/485 interface screened cables shall be used. The screen shall be

grounded.
