201
Flow Computer 2 DUT
Density Transmitter
Fail
No signal received at analog input of DUT
density sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
202
Flow Computer 2 DUT
Pressure Transmitter
Fail
No signal received at analog input of DUT
pressure sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
203
Flow Computer 2 DUT
Temperature
Transmitter Fail
No signal received at analog input of DUT
temperature sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
204
Flow Computer 2
FLASH Fail
An internal flow computer error has occurred.
Restart flow computer.
If error persists, contact Hauser.
205
Flow Computer 2
FRAM Fail
An internal flow computer error has occurred.
Restart flow computer.
If error persists, contact Hauser.
206
Flow Computer 2 I/O
Comms Fail
An internal flow computer error has occurred.
Restart flow computer.
If error persists, contact Hauser.
207
Flow Computer 2 MM
Pressure Transmitter
Fail
No signal received at analog input of MM
pressure sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
208
Flow Computer 2 MM
Temperature
Transmitter Fail
No signal received at analog input of MM
temperature sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
209
Flow Computer 2
Invalid Hardware
Version
The MM application was installed on an
incompatible flow computer.
Install application on a 3rd generation or newer
flow computer.
210
Flow Computer 2
System Restart
The flow computer has been restarted.
This is normal behavior following an intended
restart.
In any other case, contact Hauser.
211
Flow Computer 2 MM
Comms Fail
Modbus RTU communication between flow
computer and Promass MM has failed.
Check wiring of Modbus RTU (RS-485) cables.
Ensure that Promass is switched on. Check
Modbus RTU communication settings.
212
Flow Computer 2 RAM
Fail
An internal flow computer error has occurred.
Restart flow computer.
If error persists, contact Hauser.
213
Flow Computer 2 RTC
Error
An internal flow computer error has occurred.
Restart flow computer.
If error persists, contact Hauser.
214
Flow Computer 2 SD
Card Error
An internal flow computer error has occurred.
Restart flow computer.
If error persists, contact Hauser.
215
Flow Computer 2 Task
Fail
An internal flow computer error has occurred.
Restart flow computer.
If error persists, contact Hauser.
216
Flow Computer 2 Units
Mismatch Error
Settings selected for units are not plausible.
Check settings for units.
217
Flow Computer 2 Flow
Rate/Total Discrepancy
Error
The pulse input signal of the MM does not
match the Modbus mass rate signal.
Check pulse input of MM and Modbus RTU
communication. Check settings for flow
discrepancy.
250
Flow Computer 2 DUT
Density High
Upper DUT density limit has been exceeded.
Check process conditions.
Check settings for alarm limits.
251
Flow Computer 2 DUT
Density Low
Lower DUT density limit has been exceeded.
Check process conditions.
Check settings for alarm limits.
252
Flow Computer 2 DUT
Pressure High
Upper DUT pressure limit has been exceeded.
Check process conditions.
Check settings for alarm limits.
253
Flow Computer 2 DUT
Pressure Low
Lower DUT pressure limit has been exceeded.
Check process conditions.
Check settings for alarm limits.
254
Flow Computer 2 DUT
Temperature High
Upper DUT temperature limit has been
exceeded.
Check process conditions.
Check settings for alarm limits.
