Introduction
NOTE: This manual describes only the SIL related safety information for the ULTIMA X5000 to support installations where SIL certification to IEC 61508 is required.
The MSA ULTIMA X5000 Gas Monitor, hereafter also called the device, is designed to monitor the environment where mounted and alert the user to potentially dangerous levels of target gas. The ULTIMA X5000 uses various detection methods, depending on the gas of interest. Detection methods include electrochemical, infrared, catalytic bead or other technologies.
The ULTIMA X5000 is capable of communicating with and displaying information for two sensors at a time. The device generates two discrete analog outputs; one for each sensor connected to the transmitter. Each analog output is a standard 4 to 20 mA sourcing output. The analog output associated with Sensor 1 has HART (Highway Addressable Remote Transducer) communication encoded on it. If two sensors are connected, the HART communication on output 1 carries information for both sensors.
Relays and other communication protocols are available as an option.
The ULTIMA X5000 is suitable for installation in hazardous locations. It is intended for integration with a control system that can alert operations personnel to the presence of a gas alarm. The ULTIMA X5000 Gas Monitor is regarded as Type B field device per IEC 61508.
WARNING!
| • | For complete information regarding performance, installation, operation, maintenance, safety information, warnings and specifications of the ULTIMA X5000 Gas Monitor, refer to the operating manual (PN 10177361). |
| • | This safety product must be handled carefully, and installed and maintained in accordance with the associated product instruction manual. |
| • | Toxic, combustible, and flammable gases and vapors are very dangerous. Use extreme caution when these hazards are present. |
| • | The ULTIMA X Series Gas Monitor is certified as a SIL 2 capable device under IEC 61508 and must be installed, used, and maintained in accordance with this manual if compliance with this IEC functional safety standard is desired. Failure to do so can result in a reduced safety level. |
| • | Under no circumstances should this equipment be connected or disconnected when under power. This is contrary to hazardous area regulations and may also lead to serious damage to the equipment. It is, however, permissible to disconnect and replace sensors without removing power in a class I (combustible gas) area. |
Failure to follow these warnings can result in serious personal injury or death.
