The measures specified above are not necessary if the plant design precludes surges from
occurring within the system.
In particular, the design must include protective measures with respect to overvoltage,
lightning, earth grounding and plant wiring in accordance with the relevant standards and the
manufacturer's specifications.
3.1.2
Outputs
The module's output channels are used to transmit and adjust the signals between the
microprocessor systems on the central module and the actuators.
The controller continuously tests the modules. Depending on the fault, it switches either only the
affected channel off or the entire module, in which case the module is indicated as faulty. The
outputs are set to the safe de-energized state.
NOTE
Controller damage!
Do not plug the terminals for output circuits if a load is connected.
If short-circuits are present, the resulting high current may damage the terminals.
Inductive loads may be connected with no free-wheeling diode on the actuator. However, HIMA
recommends connecting a protective diode directly to the actuator.
3.1.3
Line Control
Line control is used to detect short-circuits or open-circuits and can be configured for the
HIMatrix systems, e.g., on EMERGENCY STOP inputs complying with Cat. 4 and PL e in
accordance with EN ISO 13849-1.
To this end, connect the digital outputs DO of the system to the digital inputs (DI) of the same
system as follows:
