    “Alarm Relay Test for 6666 and 6667 Monitors” on page 48 Signal Inputs for Testing a 6666 Monitor When testing any of the 6600 monitors, you must use the correct input. For the 6666, the monitor expects a range of resistance corresponding to the temperature sensor type which is preset at the factory.
  • Page 51 Testing Calibration and Relays The analog circuitry of the 6666 produces a voltage between 0.4 volts to 4.8 volts for each of the resistance ranges in the table above. For example, for suffix “B”, the analog circuit produces 0.4 volts at -20°C and 4.8 volts at 200°C. The maximum range for the monitor is 0–5 volts, which means that the transducer failure values must be set to temperatures...
