Additional Installation Tips 7 Additional Installation Tips When experiencing communication problems in for example noisy environments or when operating close to temperature limits, the following recommendations are to be noticed. 7.
Additional Installation Tips 7.2 Ethernet Connection in the Panel PC Industrial Ethernet RJ45 RJ45 1 RJ45 RJ45 Panel PC RJ45 3 2 Panel PC RJ45 4 Shielded 1-1 2-2 3-3 Short and unshielded Panel PC RJ45 8-8 5 Panel PC RJ45 0.1 uF 250 V 5351 In some industrial units for Ethernet, the RJ45 contact’s shield is connected to the chassis via a capacitor, see 1 in drawing above. The Panel PC’s Ethernet shield is directly connected to the chassis, see 2 in drawing above. 1.
Additional Installation Tips 7.3 • • • • • • • • To Achieve Better EMC Protection Initially, use the original cabling from Beijer Electronics primarily. Use shielded cables for RS232 communication. Use twisted pair and shielded cabling for RS422 and RS485. Use the cabling intended for the bus type; Ethernet, Profibus, CC-Link, CAN, Device Net etc. Install and connect according to applicable specifications for the relevant bus standard.
Additional Installation Tips 7.4 Ambient Temperature The maximum ambient temperature for the Panel PC is provided in the specifications. The ambient temperature refers to the temperature in the device cabinet which cools the Panel PC’s electronics.
Additional Installation Tips 7.5 Safety Most of the Panel PCs are fed with 24 V DC. Power supply 230 V AC to 24 V DC Panel PC +24 V 1 0V 4 Power supply 230 V AC to 24 V DC Panel PC +24 V 2 0V 4 Distance? Power supply 230 V AC to 24 V DC Panel PC +24 V 3 0V 4 COM1 Small controller with expansion unit Ch0 Ch1 230 V AC COM100 Ch100 Ch101 5355 If you use a power supply that meets safety standards and only feeds the Panel PC, there is no problem. See 1 in drawing above.
Additional Installation Tips 7.6 Galvanic Isolation Internal electronic Filter Ethernet DC/DC galvanic isolation DC/AC VCC +24 V DC CFL 0 V (GND) 0V 1.5 m RS422/485 RS232 USB 5356 USB The Panel PC has galvanic isolation against the 24 V DC feed but no galvanic isolation between the communication ports for RS232, RS422/485 and USB. Only the Ethernet connection has galvanic isolation.
Additional Installation Tips 7.7 Cable and Bus Termination RS485 Use shielded and twisted pair cable. The pair capacitance may not exceed 52.5 pF/m and area at least 0.25 mm2 (AWG 24), if you want to use the maximum transfer distance and maximum transfer speed. 0 V, the reference voltage for communication should be included in the cabling. With two-way communication use two pairs; one pair for communication and one pair for 0 V. The shield must be grounded at one end.
Fault Tracing 8 Fault Tracing This section includes different fault scenarios and steps to follow to trace the fault. The EPC TA150 AM is not working properly, and the power LED is off 1. 2. 3. 4. 5. Is the power voltage correct? Does the power supply deliver enough current? Check the fuse. Check the power card. Is the power card correctly mounted? The EPC TA150 AM is not communicating 1. Check the communication cable between the units. 2. Check the communication ports on the CPU board.
Fault Tracing The touch screen is malfunctioning or is not responding at all 1. Re-calibrate the touch screen according to the Calibrating the Touch Screen section. 2. Check that the flex cable is correctly fitted. 3. Replace the display of the Panel PC according to the Replacing the Display/Display Cable section. 4. Check the touch interface on the power card. Lines in display have wrong color or the display picture is shifted 1.
Software 9 Software This chapter describes how to maintain and update the operating system in the EPC TA150 AM, and instructions about how to recover the operating system. 9.1 General Information about Software The EPC TA150 AM is delivered with an image (operating system) pre-stored in the Nand Flash memory. 9.1.
Software 9.2 Update or Customize Software A customized operating system image can be developed with the needs of the customer. In this case, please contact Beijer Electronics sales office for detailed information. 9.2.1 Backup and Recovery It is important to generate a backup image of the operating system. In case of emergency, a recovery can be done in minutes using a backup image. Several programs on the market are suitable for this.
Environmental Aspects 10 Environmental Aspects This chapter includes information about the environmental impact of the EPC TA150 AM. More information can be found on the manufacturer’s web site. 10.1 General Environmental Aspects The manufacturer’s activities meet internal requirements as well as those of the SS-EN ISO 9001:2000 and SS-EN ISO 14001:2004 international standards. 10.2 Environmental Impact of the Panel PCs 10.2.
Environmental Aspects 10.3 Recycling The Panel PCs consist largely of aluminum. It is a great advantage in terms of both resources and the environment if it can be recycled. Make sure that Panel PCs taken out of service are sent to facilities for electronic scrap. The manufacturer’s electronic waste is recycled by Stena Technoworld AB. Aluminum front/rear casings and other covers can be removed and recycled. Plastic display frames and CF covers must be recycled as hard plastic.
