| Sensor error detection | Input Types Otder Than B: A Sensor error is detected and tde Sensor Error Flag is turned ON if tde upper or lower limit of tde set input range is exceeded by 20°C or 20°F. The process value overrange direction when a Sensor error occurs can be specified (high: set input range +20°C or +20°F, low: set input range -20°C or -20°F). B Input Type: A Sensor error is detected and tde Sensor Error Flag is turned ON if tde upper limit of 1,820°C or 3,220°F or tde lower limit of 0°C or 0°F is exceeded. The process value overrange direction when a Sensor error occurs can be specified (high: set input range 1,820°C or 3,220°F, low: set input range 0°C or 0°F). | |
| Function | Process value alarm | Process value 2-point alarm (HH, H, LL, L), alarm hysteresis, and ON-delay timer (0 to 60 s) are available. External alarm outputs: One per input (H or L). |
