High Alarm:
The Omron E5CN temperature controller incorporates an independent high-temperature
alarm. Alarm 1 (AL-1) prevents heater operation above a preset maximum temperature
that may harm the process and potentially the tank material. If the process temperature
exceeds the preset high alarm value, the heater will be disengaged and the audibly
alarm will sound. The temperature controller will activate once the process temperature
exceeds the set point by the preset value. The factory setting of this alarm temperature
is 248°F (120°C).
The high alarm value can be adjusted to a lower setting through the operations level.
