Resetting to standard
After a restart (voltage supply was interrupted), the error memory is reset. Writing 0x0001 in register address 00201 has the
same effect.
Description of the error memory
Bit Description
Pressure signal above the upper limit value (in bar abs., →see data sheet SP 60.77)
1
3 Temperature signal below the lower limit value (< -40 °C [-40 °F])
4 Temperature signal above the upper limit value (> 80 °C [176 °F])
5 Communication error pressure/ temperature sensor
6 Liquefaction of the SF
7 Gas density above the upper limit value (based on the full scale of the density measuring range in bar abs. at 20 °C [68 °F])
10
Recurring Modbus
Example: 0x0082
Bit 1 and 7 are set. The upper limit values for pressure and gas density are exceeded.
Software reset
Writing 0x0001 in register 202 causes a software reset. After this process all changed parameters take effect (e.g.
change of address).
Reset to factory settings
Writing 0x0001 in register 203 causes the transmitter to be reset to its factory settings and a software reset to be
carried out. After this process, all writable registers are reset to the basic setting.
