ETD-SL-1T-S Star/delta timer relay INTERFACE Data sheet 102573_en_06 1 © PHOENIX CONTACT - 09/2009 Description Increasingly higher demands are being placed on safety and system availability – across all sectors. Processes are becoming more and more complex, not only in mechanical engineering and the chemical industry, but also in plant and automation technology. Demands on power engineering are also increasing constantly. The timer relays in the ETD series can be used to control time sequences in production and process technology. Features – – – – – – One adjustable time Time range of 500 ms to 3 minutes (four setting ranges) Additional changeover time Star/delta startup Power supply via power module can be selected Two floating PDTs WARNING: Risk of electric shock Never carry out work when voltage is present.

To install the power module in the relay housing, remove the transport casing and position the power module in the recess in the side of the housing (ensure that it is the right way round). The red locking latches snap in with an audible click when the power module is securely positioned. To remove the power module, press the two red locking latches together and pull out the power module. 8 Installation WARNING: Risk of electric shock Never carry out work when voltage is present. The module can be snapped onto all 35 mm DIN rails according to EN 60715. 102573_en_06 PHOENIX CONTACT 4 ETD-SL-1T-S 9 Time setting Example: A1 .4 2 .6 .8 .2 1 .0,5 Timer U/tY 1 15 TIM E Y 1 80s 30s 3 Set time: 0.5 * 1 minute = 0.5 minutes = 30 seconds Setting of the turnaround time, e.g. 80 ms 10 10s 3 2 Specification of the time end range using a rotary switch, e.g. 1 m (1 minute) Fine setting of the time using a potentiometer, e.g. 0.5 60 80 10ms 40 REL ETD-SL-1T-S TIME Y>A 10 25 26 28 16 18 A2 Diagnostics The LEDs indicate the following error states: "U/tY" LED (Green) – – LED flashes: Voltage present, set star time t1 running LED ON: Voltage present, set star time t1 has elapsed "REL" LED (Yellow) – – LED ON: Output relay has picked up LED OFF: Output relay has dropped out 102573_en_06 PHOENIX CONTACT 5 ETD-SL-1T-S 11 Connection example A1 12 15 15 25 16 18 26 28 25 26 28 16 18 A2 Function ATTENTION: Module can become damaged Only set the functions when the module is switched off. S: Star/Delta Startup U LED U/tY LED REL, R 15-16-18 R 25-26-28 t1 102573_en_06 t2 t1 t2 When supply voltage U is applied, the output relay for the star contactor picks up (yellow "REL" LED is ON) and set star time t1 starts running (green "U/tY" LED flashes). Once the star time has elapsed (green "U/tY" LED is ON) the output relay for the star contactor drops out (yellow "REL" LED is OFF) and set changeover time t2 starts running. Once the changeover time has elapsed, the output relay for the delta contactor picks up. In order to restart the function, the supply voltage must be interrupted and applied again.
