Warnings warn users about hazards when handling the product. The hazards are classified, specified, described and supplemented with information about how to avoid them.  If there is a warning before a list of instructions, the hazard is present throughout the entire activity. If there is a warning immediately before an instruction, the hazard is present during the next step. All warnings are indicated by a signal word and a warning symbol. The different combinations of the signal word and warning symbol indicate the degree of danger. DANGER For an immediate hazard that will result in severe...

Hazard symbols Note The warning symbol may be present alongside another hazard symbol that represents the type of hazard, in order to attract the reader's attention. Hazard symbols are indicated by a triangular symbol in the context of warnings. The following hazard symbols are used in this documentation: Electric shock – dangerous voltage!

Product description Product description The SAFEONE DN3PD2 is a safety switchgear for sensorless speed monitoring of electric drives.  The readiness for operation and the switching status of the contact outputs are displayed via LEDs. The device has a standard USB connection. The configuration software GO:BEYOND enables a simple parameterization and online monitoring. The device is intended for mounting on a 35mm standard rail. Function description The two-channel evaluation unit of the safety switchgear module measures the frequency of the effective rotating field of the motor at the measuring...

Product description Monitoring of a speed range without startup monitoring fmin: minimum frequency If fmin is undershot, the output contacts (13-14 / 23-24) switch off. They switch on again after the acknowledgment via the acknowledgment input Q. Depending on the acknowledgment mode, the switch-on-conditions differ. Please note the chapter "Startup monitoring". If fmin = 0 there is no monitoring to a minimum speed. The output contacts remain closed at standstill. fmax: maximum frequency If fmax is exceeded, the output contacts (13-14 / 23-24) switch off. They switch on again after the acknowledgment...
