Limitorque MX DeviceNet Field Unit FCD
7.CLOSE INHIBIT must be configured for desired function and properly wired.
8.Remote control is not selected if not in use. Properly wired if selected.
9.Confirm there are no duplicate DeviceNet addresses.
10.Confirm that ground is at one end only per network cable segment.
11.Confirm protocol, baud rate
Main power supply must be within +/- 10% of nominal unit power rating at all times. Refer to nameplate for voltage.
UPS of 24 V DC must be within +/- 10% at all times.
7.1Workmanship
The Limitorque MX is
Practice all plant and safety codes and standards. Failure to follow instructions can result in personal injury and/or property damage.
Do NOT remove covers of Division 1 units with power applied to prevent the possible ignition of hazardous atmospheres.
Qualified technicians should perform all service. Dangerous voltages may be present on the circuit boards and terminations.
Use extreme caution when working around power input cables. These cables have potentially lethal voltages on them.
Replace fuses only with specified parts for continued safe operation.
Have qualified personnel verify all wiring and connections against vendor drawings prior to energizing the equipment. Incorrect wiring and/or connections can result in equipment damage.
aCAUTION: There is potential to cause electrostatic damage to electronic components. Before handling electronic components, ensure that you are discharged of static electricity by briefly touching a grounded metal object.
The circuit boards in the MX DeviceNet contain components that are subject to damage from electro- static discharge (static electricity). The following precautions and procedures are recommended when handling circuit boards and components. Failure to observe these practices when handling and shipping circuit board products may void your warranty.
•Keep plastics and other materials prone to the buildup of electrostatic charges (static electricity) away from boards, components, and work area.
•Avoid synthetic or wool clothing; wear cotton or cotton blend materials. Keep components and circuit boards away from clothing and hair.
•Discharge static electricity on your body by touching and momentarily holding a grounded metal object before handling electronic components. This is especially important after walking across
carpeted areas. | 39 |
•Handle components in the field as little as necessary.
•Handle components only by the edges, and avoid contact with leads, circuits, or connectors.
