The central unit has an internal battery that powers the clock
when the unit is turned off. If date and time are required on
power, the backup battery may be discharge and / or faulty,

Function Codes and Reading
• The sensor status reading is done through the command Read Holding Registers (code 03).
• For each gas detector (sensor) are available 2 registers (non-consecutive).
• The registers can only be read.
• 1 to 200 are the registers with the current values (same numbering of the sensors).
• 301 to 500 are the sensor status registers (the register 301 contains the status of the sensor 1).
• NOTE: The value of a "NOT CONFIGURED" sensor is always 0.
• Since the submitted values, are the word (16-bit signed), to represent decimal numbers, certain
values are multiplied by a factor determined by the number of decimal places specified in the
configuration of the sensor. If the decimal digits are 0, the value does not undergo multiplication.
With a number, multiply it by 10, with 2 digits for 100 and 3 figures for 1000.
• As for the status of the sensors, the table below explains the meaning of the possible values.
The table specifies the meaning of the possible values, of the sensor status.
