Chapter 2 Introduction System configuration example This unit is designed to fulfill the specifications when used under the following configuration. Point Always combine the components of this unit (FL sensor, FW extension cable, and FK driver) so that it will be configured as follows. If this unit is not configured as shown below, or if the FW extension cable is not used in combining the FL sensor and FK driver, the output characteristics will differ dramatically.
Chapter 3 Installation Chapter 3 Installation WARNING Installation work, wiring and connections must be performed by a person with knowledge in instrumentation. Always perform grounding. Never apply power until all wiring work and connection work has been completed. If this is not followed there is a possibility of electrocution. ATTENTION Before touching this unit, be sure to touch a metal section near by to discharge any static electricity.
Chapter 3 Installation Installation environment 3.1.1 FK driver installation environment Install the FK driver in a location that satisfies the following environmental and install conditions. ▊ Environmental conditions ▊ Ambient Must be in a range between -40 to 80 °C when devices are temperature : operating.
Chapter 3 Installation 3.1.2 FL sensor installation environment Install the FL sensor at a location that satisfies the following environmental and install conditions. ▊ Environmental conditions ▊ Ambient temperature: Must be in a range between -40 to 125 C when devices are operating.
