User manual OMRON E5CN-U DATASHEET

[. . . ] Basic-type Digital Temperature Controller E5CN/E5CN-U (48 x 48 mm) New 48 x 48-mm Basic Temperature Controller with Enhanced Functions and Performance. Improved Indication Accuracy and Preventive Maintenance Function. · Indication Accuracy Thermocouple input: ±0. 3% of PV (previous models: ±0. 5%) Pt input: ±0. 2% of PV (previous models: ±0. 5%) 48 × 48-mm 48 × 48-mm Analog input: ±0. 2% FS (previous models: ±0. 5%) E5CN E5CN-U · New E5CN-U Models (Plug-in Models) with analog inputs and current outputs. · A PV/SV-status display function can be set to alternate between Refer to Safety Precautions on page 18. displaying the PV or SV and the status of the Temperature Controller (auto/manual, RUN/STOP and alarms). [. . . ] Otherwise, minor injury from explosion may occasionally occur. Do not leave the cable for the Support Software connected to the product. Malfunction may occur due to noise in the cable. Do not use the Temperature Controller or Conversion Cable if it is damaged. Doing so may occasionally result in minor electric shock or fire. Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. CAUTION - Risk of Fire and Electric Shock a) This product is UL listed as Open Type Process Control Equipment. It must be mounted in an enclosure that does not allow fire to escape externally. b) More than one disconnect switch may be required to de-energize the equipment before servicing the product. c) Signal inputs are SELV, limited energy. 1 d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2 circuits. 2 If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. The life expectancy of output relays varies considerably with the output load and switching conditions. Tighten the terminal screws to between 0. 74 and 0. 90 N·m. 3 Loose screws may occasionally result in fire. Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents. A malfunction in the product may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the product, take appropriate safety measures, such as installing a monitoring device on a separate line. A semiconductor is used in the output section of long-life relays. [. . . ] Check the specifications of the case and Temperature Controller before removing the Temperature Controller from the case. Tool insertion hole Flat-blade screwdriver (Unit: mm) (1) (2) (3) (1) 0. 4 2. 0 1. Insert a flat-blade screwdriver into the two tool insertion holes (one on the top and one on the bottom) to release the hooks. Insert the flat-blade screwdriver in the gap between the front panel and rear case, and pull out the front panel slightly. Hold the top and bottom of the front panel and carefully pull it out toward you, without applying unnecessary force. [. . . ]
