WARNING
Connect the ground of the actuator to the ground terminal point of the corre‐
sponding output on the IndraControl S20 plug. Using an external ground is
not permitted.
The module is provided with safe digital outputs that can be used as follows:
● For dual-channel assignment: Four dual-channel outputs
● For single-channel assignment: Eight single-channel outputs
For technical data of the safe outputs, refer to
on page 58.
The safe digital outputs of the module can be parameterized in pairs. Thus,
the outputs can be adjusted to different operating conditions and different
safety integrities SIL, SILCL, cat., PL can be implemented.
For a high error detection, switch-on the test pulses. If it is not possible to
switch on the test pulses for the connected loads, the test pulses can be
switched off. However, the error detection rate is then lower.
The attainable safety integrity (SIL, SILCL, cat., PL) and error de‐
tection depends on the parameterization, the design of the actua‐
tor and the cable routing, refer to
ples of the safe outputs" on page
For information on the parameterization of the outputs, refer to
"Parameterizing the safe outputs" on page
It is diagnosed via the local diagnostic displays as well as via the diagnostic
messages transferred to the control.
For information on the local diagnostic displays, refer to
diagnostic and status displays" on page
For information on the diagnostic messages of the outputs, refer to
