2 Check Measure sensor
electrical resistance
W Single bit
Coil 0, Restart, when 0xFF00 is written to this coil the sensor will restart. If applied, a
new Modbus address or new serial settings will become effective.
Coil 2, Check, when 0xFF00 is written to this coil the internal electronics will measure the
electrical resistance of the thermopile. After the measurement, a new value will be
written into register 7. Requesting to write this coil with a high repetition rate will result
in irregular behaviour of the sensor; the check must be executed as an exceptional
diagnostics routine only.
