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
1 Pressure signal above the upper limit value (in bar abs., →see data sheet SP 60.77)
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
Liquefaction of the SF
6
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])
Recurring Modbus
10
Example: 0x0082
Bit 1 and 7 are set. The upper limit values for pressure and gas density are exceeded.
