Page 11: Self-Diagnostic Function
Operating Instructions Temperature Indicating Controller CF1M (2) Self-diagnostic function The CPU is monitored by a watchdog timer, and when any abnormal status is found on the CPU, the controller is switched to warm-up status. (3) Automatic cold junction temperature compensation (thermocouple input type) Detects the temperature at the connection terminal between thermocouple and instrument, and always keeps it on the same status as when the reference junction is located at 0°C (32°F). - Page 12 Operating Instructions Temperature Indicating Controller CF1M 6.2 ON/OFF action drawing Action Heating (reverse) action Cooling (direct) action Hysteresis Hysteresis Control action Setting Setting Relay contact output Non-contact 12Vdc 0Vdc 0Vdc 12Vdc voltage output Current output 20mAdc 4mAdc 4mAdc 20mAdc Indicator (OUT) Green Unlit Unlit...
