Key coding switch
For setting the limit value from 0...99% of the configured signal range in steps of 1%.
At two-position-control ∆s the limit value A represents the switching value and the limit value B the switching back value.
Configuration switches
The configuration of the input signal range as well as the relay functions is made per dip switches inside the housing.
Dangerous voltage
Ensure a safe switching off the supply voltage when opening the housing
For configuration release the upper housing part at top and bottom side behind the terminals by using a screwdriver and pull
it out of the housing. Drop-in pin's avoid a complete pulling out. Following the respective dip switches can be set according to
the desired functions to ON or OFF.
