Operating Instructions Temperature Indicating Controller CF1M 3.6 Control output OFF function Character Name, Descriptions Control output OFF function • This is the function to switch the control output OFF even if power is supplied to the instrument. The function is used when required to halt the control action or the CF1M is not used in multiple controllers. " is indicated on the PV/SV display. " • This function can be selected from any mode or any setting item by pressing the OUT/OFF key for approx.
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). 6.

Operating Instructions Temperature Indicating Controller CF1M Option: Heater burnout alarm output (1) This alarm is not available for detecting current under phase control. (2) Use the current transformer (CT) supplied and pass one lead wire of heater circuit into the hole of the CT. (3) When wiring, keep CT wire away from AC source and load wire to avoid external interference. 8 9 CT input terminal Power source CT [Fig. 7-2] Heater 8. Specifications 8.
Operating Instructions Temperature Indicating Controller CF1M Temperature alarm output The alarm action point is set by ± deviation to the main setting (except Process value alarm). [When the alarm action is set as energized] When the input exceeds the range, the output turns ON or OFF (in the case of High/Low limit range alarm). [When the alarm action is set as deenergized] The output acts conversely. • Setting accuracy Thermocouple : Within ±0.
Operating Instructions Temperature Indicating Controller CF1M Insulation resistance 10MΩ or greater at 500Vdc In the case of the above Circuit insulation configuration (*), because the communication and output terminals are not isolated from one another, the insulation resistance test must not be carried out. Dielectric strength Between input terminal and ground ---------------- 1.5kVac for 1 minute Between input terminal and power terminal ------ .1.
Operating Instructions Temperature Indicating Controller CF1M Heater burnout alarm [Option code: W1X] Watches the heater current with CT (current transformer), and detects the burnout. This option cannot be applied to the type current output. When the option [SV2] or [CR5] is applied, the option [W1X] cannot be applied together. Rating : 5A [Option W10], 10A [Option W11], 20A [Option W12] or 50A [Option W15] Setting range : In the case of 5A, 0.0 to 5.0A (off when set to 0.0) In the case of 10A, 0.0 to 10.
