2 Intended use • The safety switchgear unit is for the monitoring of a minimal and a maximal speed of drives using by machine tools without sensors. • According to VDE 0113 T.1 the unit can be used in safety current circuit. • Depending on the external wiring maximal category 4/ PLe according to EN IOS 13849-1 respectively SIL 3 according to EN 61508 can be achieved. (•'\ This document is to use for the product DN3PD1 and is according the contently requirements of an original instruction manual Original Instruction Manual 04/18 Date: 2018-02-20 5 of 16

3 Safety regulations • The device must only be installed and activated by an electrician or trained persons who are familiar with these operating instructions and the applicable regulations regarding work safety and accident prevention. • Observe the VDE, EN and local regulations, particularly respecting to the protective measures. • Without observing the regulations may result in death, severe bodily injury or extensive property damage. • For emergency-stop applications, either the integrated function for restart interlock must be used or automatic restarting of the machine must be...

DN3PD1 Important notes and validation 4.1. Function Description • The two-channel control monitor of the safety switch-gear module measures the frequency of the effective rotating field of the motor at the measuring terminals L1, L2 and L3, • An undercut or an exceeding of the configured switching threshold frequency (V-LIMIT 1 and V-LIMIT 2) an internal or an external error opens immediately the enabling circuits 13/14, 23/24. The unit is in safe switching status • There is a load depending slip between motor speed and rotating field frequency if an asynchrony motor is used. This must be...

5 Usage 5.1. Operation with frequency converter • An operation at electrical power drive systems with adjustable speed is possible. (Frequency converter) • The monitored frequencies can be configured at the module • The safety switch-gear module switches off the output contacts, if the effective rotating field frequency is outside of the adjusted switching threshold frequency 5.2. Operation at motors with star-triangle • Motor with star-triangle circuit • The operation with star-triangle circuit or pole changeover is possible. • The Terminals L1 and L3 have to be directly connected to as...

• Mounting on 35mm DIN rail according to EN 60715 • For the replacement pull the lock device using a screwdriver • Meeting the pitch according to DIN EN 50274, VDE 0660-514. • No strong magnetic fields in the installation vicinity. • These can interfere with the unit. • Magnetic fields < 30 A/ m • Wires with cross section of 1.5 mm2 are to use. • Copper wires up to 60°C/75°C approved are obligatory. • Using of wire end sleeve is required. • Loads connected to the measuring wires are not allowed. • The laying of the measuring wires has to avoid a cross connection or short. Laying in cable...

DN3PD1 Configuration of the switching threshold 7.1. Important notes to the Configuration • To activate the SET-button use an isolated screwdriver according to EN 60900 to use. • Activate the SET button to display the present adjustments. The adjustments are displayed one after the other. • The correct configuration of the switching threshold and the quit-function is the requirement for a safe function and is in the responsibility of the user. • The output contacts are switched-off during the configuration. • No saving of the parameters by voltage break or break of the configuration for...
