1)
Limit the individual conductor resistance to the specified values to ensure that the light curtain functions
correctly. (Also observe IEC 60204-1.)
The specified values apply to the total resistance of each wire including contact and connector resis‐
tances.
2)
If a T distributor is used, the specified values apply to the resistance of the entire cable from the system
connec
tion of the device to the connection in the control cabinet.
For a cascade, the specified values apply to the resistance of the entire cable from the system connec‐
tion of the last guest device to the connection in the control cabinet.
