4.1.1.1
Surges on Digital Inputs
Due to the short cycle time of the HIMatrix systems, a surge pulse as described in
EN 61000-4-5 can be read in to the digital inputs as a short-term high level.
The following measures ensure proper operation in environments where surges may occur:
1. Install shielded input wires
2. Program noise blanking in the user program. A signal must be present for at least two cycles
before it is evaluated. The fault reaction is triggered with a corresponding delay.
i
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
instructions specified in the system manual (HI 800 141 E or HI 800 191 E).
