Page 6: Intended Use
DN3PD1 Intended Use Intended Use Safety switchgear to monitor the speed of three-phase and single-phase motors without sensor. • Two speed thresholds are possible: minimum speed and maximum speed. • The unit meets Cat. 4/ PL e acc. to ISO 13849-1, SIL (CL) 3 acc. to IEC 62061 and IEC 61508. -
Page 7: Safety Regulations
Properly dispose of the device at the end of its service life. • If these regulations are not adhered to or in the event of improper use, DINA Elektronik GmbH accepts • absolutely no liability for the resulting property damages or personal injury. -
Page 8: Function Description
DN3PD1 Function description Function description The two-channel evaluation unit of the safety switchgear module measures the frequency of the effective rotat- ing field of the motor at the measuring terminals L1, L2, L3. If the parameterized switching threshold frequencies are exceeded or undershot (V-LIMIT 1 and V-LIMIT 2), or an internal or external fault exists, the enabling current paths 13/14, 23/24 open immediately. -

Page 16: Diagnostics
DN3PD1 Diagnostics Diagnostics The 2-color LEDs (b1, b2, b4, b8) indicate operational readiness, switching status, internal and external errors. The semiconductor output O1 is switched on when the frequency is within the parameterized range. See Fig. 8-1 The semiconductor output O2 indicates the operational readiness. This switches off in case of an error. -
