FTS14 communication interface for the Eltako RS485 bus with included switching power supply FSNT14-12V/12W. Standby loss only 0.4 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. Supply voltage 12V DC. Connection to the Eltako RS485 bus. Cross-wiring of bus and power supply with plug-in bridges. The scope of delivery includes 1 switching power supply FSNT14-12V/12W, 1 spacer DS14, 2 plug-in terminating resistors with ¿ imprint, 1/2 TE, 3 plug-in bridges 1 TE (including 1 spare), 1 plug-in bridge 1.5 TE, 2 plug-in bridges 1/2 TE (including 1 spare) and a plug-in bridge assembly tool SMW14. If the load of the switching power supply is greater than 4W, a ventilation distance of ½ division unit must be maintained on the left-hand side from neighboring devices. If the load is greater than 6W, an additional ventilation distance of ½ division unit is required between the FSNT14 and the FAM14 with the DS14 spacer. A DS14 spacer and a long jumper are therefore included. If the total power requirement of a series 14 bus system is higher than 10W, an additional FSNT14-12V/12W must be used for every 12W of additional power requirement. Optionally, 12V DC can also be fed into the GND/+12V terminals. Cross-wiring of bus and power supply with jumper. The enclosed second terminating resistor must be plugged into the last actuator. Mini USB for connecting a PC to create a device list, to configure the actuators using the PCT14 PC tool and for data backup. A legalization code for downloading the PCT14 from the Eltako homepage www.eltako.de is included with the FTS14KS. All FTS14EM and, if applicable, FGW14 gateways are connected to the Hold terminal if they connect a PC with an RS232 bus. The BA operating mode rotary switch can be used to set 10 different operating modes in accordance with the operating instructions. The LED at the bottom lights up green when a connection has been established by the PCT14 PC tool. The green LED flickers when data is being read or written. The green LED goes out when the PCT14 PC tool has disconnected the connection.
