1 Preliminary note This document applies to devices of the type "compact speed monitor" (art� no�: DI502x and DI52xA)� This document is intended for specialists� These specialists are people who are qualified by their training and their experience to see risks and to avoid possible hazards that may be caused during operation, installation or maintenance of the device�...
2 Safety instructions A qualified electrician must connect the unit� Observe the national and international regulations for the installation of electrical equipment� 2.1 ATEX units (DI52xA) Remarks for safe use in hazardous areas: operating instructions (Ex protection related part) for speed monitors according to EU directive 2014/34/EU annex VIII (ATEX) group II, equipment category 3D�...
3.3 Damping The yellow LED indicates the damping status of the sensor irrespective of either the switching function or the switching status of the transistor output� Sensor LED yellow undamped damped 3.4 Function diagram [Imp/min] SP + Hy 1: Voltage supply SP = switch point 2: Start-up delay Hy = hysteresis...
3.5 IO-Link IO-Link allows the configuration of internal parameters such as start-up delay and switching behaviour (normally closed/normally open) as well as reading the current measured values� Furthermore IO-Link protects against signal faults and measured value losses as well as tampering with the sensor� You will find the IODDs necessary for the configuration of an IO-Link device and detailed information about parameter setting tools, process data structure, diagnostic information and parameter addresses at www�ifm�com/gb/io-link�...
5 Electrical connection ► Disconnect power� ► Connect the device according to the wiring diagram� 5.1 Wiring DI5020, DI5021 DI5022, DI520A BK = black BN = brown BU = blue DI5026, DI523A BK = switching output / IO-Link / PNP / NPN programmable 6 Setting 1: Multi-turn potentiometer for switch point setting (without end stop)
► Keep the minimum speed to be monitored in the plant on a constant level� ► Connect the device to supply voltage� ► Wait until the start-up delay is over (→ 8 Technical data)� ► Set the switch point depending on the status of the green LED� 6.1 Setting for switching function normally open When the green LED does not light: - Turn the pot slowly anticlockwise (-) until the green LED lights�...
