Description
In the event of an alarm, the instrument latches the fault conditions until reset by the operator. The reset can be run by the operator from the front key (red R), from the digital input (optional), or serial line (optional). The displays show the process values, plus multilingual scrolling messages for diagnostics and alarms. Configuration and unit operation is done with the front keys. 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 The devices offer complete diagnostics (broken or incorrect connection of sensor), operation count, settable alarm limits (useful for scheduling preventive maintenance) A trigger meter and alarm memory reset timer is available Description • Safety high-temperature alarm threshold with1250L Indicator/Safety Alarm Limit (FM)
Indicators 1250 L are used to limit overheating in industrial processes.
