Simplicity on the Worksite Solutions Guide for FAQs: E5CC/E5EC Setting Temperature Alarms What Is Alarm Hysteresis? The alarm hysteresis is the difference between the temperature where the alarm output turns ON and the temperature where it turns OFF. The default setting is 0.2°C • Setting Hysteresis for an Upper-limit Alarm (Alarm Type 2) • Setting Hysteresis for a Lower-limit Alarm (Alarm Type 3) Example: Hysteresis = 1 Example: Hysteresis = 1 Alarm hysteresis: 1°C Alarm hysteresis: 1°C If the temperature decreases, the alarm output will turn OFF at 99°C. Alarm ON 100°C or higher Alarm ON 100°C or lower If the temperature increases, the alarm output will turn OFF at 101°C.
• Setting Hysteresis for an Upper-limit Lower-limit Alarm (Alarm Type 1) Example: Hysteresis = 1 Alarm hysteresis: 1°C Alarm hysteresis: 1°C Setting Temperature Alarms Note: The same hysteresis is used for the upper and lower limits of an upper-limit and lower-limit alarm and an upper-limit and lower-limit range alarm Simplicity on the Worksite Solutions Guide for FAQs: E5CC/E5EC 4-9 S tep 3 Additional Settings as Required 1 Determining the Alarm Hysteresis (Deviation between ON and OFF) ON ON ON ON ON Alarm ON Alarm ON 80°C or lower If the temperature 120°C or higher increases, the alarm output will If the temperature turn OFF at 81°C. decreases, the alarm output will turn OFF at 119°C.
