1250L Indicator/Safety alarm limit (FM)
Overview
- Indicators 1250 L are used to limit overheating in industrial processes.
- In the event of an alarm, the instrument latches the fault conditions until reset by the operator. A reset can be run by the operator from the front key (red R), from the digital input (optional), or serial line (optional).
- As an additional feature, the instrument counts the number of times the alarm limit is exceeded and the total amount of time the alarm is active.
- This information can help to evaluate furnace deterioration and plan maintenance work.
- The displays show the process values, plus multilingual scrolling messages for diagnostics and alarms.
- The 1250 L model includes a segmented bar that graphically displays the temperature deviation from the alarm limit.
- Configuration and unit operation are done with the front keys.
- The keys have dual-function LEDs indicating the pressing of the keys. The LEDs provide feedback for pressed keys and also provide guidance for permitted operations.
- Initial commissioning is simplified by guided configuration text prompts that cover the commonly used base parameters accompanied by in-line help messages.
- With GF_eXpress software and PC, you can program the extended configuration, create recipes and update the firmware without having to apply power to the instrument.
- Thanks to the Smart Configurator function, you obtain the required configuration by answering a few simple questions.
- The initial parameters can always be reset, both from the keypad and from the GF_eXpress software.
- The devices offer complete diagnostics (broken or incorrect connection of sensor), operation count, and settable alarm limits (useful for scheduling preventive maintenance) A trigger meter and alarm memory reset timer are available for alarm 1.
- Maintenance of the system in which the device is installed is made easier by the ability to replace the instrument at any time simply by removing it from the faceplate.
- No additional steps are needed.
