1.1Warning Notices
This manual contains notices that you must observe for your personal safety and to prevent damage to property. Notices concerning your personal safety are highlighted by a warning triangle; notices concerning damage to property alone appear without a warning triangle. Depending on the hazard level, the warning notices are shown as follows, in decreasing order of severity.
If more than one hazard level applies, the warning notice for the highest level is always used.
If a warning notice with the warning triangle warns of personal injury, a warning of damage to property can also be added to the same warning notice.
1.2Qualified Personnel
The product/system described in this documentation may only be handled by personnel qualified for the task in question, in compliance with the documentation for that task, in particular the safety instructions and warning notices it contains. Because of their training and experience, qualified personnel are able to recognize risks and avoid possible hazards when working with these products/systems.
1.3Intended Use
1.3.1Permitted Use
With this device (PWZ – Phasen-Winkel-Zuschaltung, phase-angle switching), you can synchronize asynchronous switching signals to a reference signal to switch them at an adjustable phase angle:
- The (asynchronous) digital inputs can be activated at any time, for example by a PLC.
- As soon as the PWZ has detected such a start condition, the input signal is passed on to the corresponding digital output.
However, the switching operations (activation and deactivation) at the outputs do not take place at an arbitrary time, as they do at the input, but at a configurable time (which corresponds to a phase angle). The module knows the current phase angle from the reference input (AC voltage with a frequency of about 50 Hz).
