Information!
With this setting it is also possible to easily change an EKS in case of need for replacement. For this
purpose the suffix number for the old EKS is set on the new EKS via DIP switch S2 and the new EKS
then fitted.
6.2 Connection of power supply
(For information on pin assignment see section 4.3.2 Plug-in screw terminals for power supply )
It is imperative that the following points are observed:
f The connections must be made as appropriate to maintain EMC performance.
f A power supply of suitable EMC performance must be used for the power supply.
f Conductor cross-section maximum 1.5 mm².
f Tighten the terminal screws on the plug to 0.22 Nm.
6.3 Connection of function earth
The function earth is connected via terminal 3 on the plug-in screw terminals for the power supply. This
connection is electrically connected internally to the housing of the Electronic-Key adapter.
Information!
The function earth must be connected to PE!
6.4 Connection of the switched outputs (for EKS FSA only)
Warning!
Incorrect connection or errors in the safety-related integration of the EKS FSA can lead to fatal injury.
For this reason, observe the following safety aspects:
f It is not possible to generate a safe signal by using only the switched outputs LA1/LA2 and
LB1/LB2. Safe, downstream evaluation is always necessary (e. g. using a safety relay). Use of the
switched output LB1/LB2 as an alternative to the data line is optional.
f The safe evaluation must always be dual-channel. For this purpose, there are two alternatives:
1. Evaluation of output LA1/LA2 as channel LA together with an evaluation of the data line as
channel LB (recommended)
2. Evaluation of output LA1/LA2 as channel LA together with the output LB1/LB2 as channel LB
f Integrate the EKS FSA as defined in the following connection examples from EUCHNER.
