Alarms raised by the
Sarasota HME900 density
converter.
Typical alarms for the Sarasota HME900 density converter
are:
- Error 01 LSL: Lower sensor limit alarm
- Error 02 USL: Upper sensor limit alarm
- Error 03 EEPROM: Electrically Erasable Programmable
Read-Only Memory error
- Error 04 ADC: Analog-to-digital converter error
- Error 05: Pressure input error
- Error 06: PRT input error
- Error 07: Period input error
- Error 08 RAM: RAM error
- Error 09 ROM: ROM error
This section provides basic troubleshooting steps for problems that may
arise when using the Thermo Scientific Sarasota CM515 density converter
with the Sarasota SG901 with frequency output.
Caution
This section provides troubleshooting guidance to instrument
technicians experienced with working on process instruments with low and
medium voltage supplies, intrinsically safe or explosion proof / flame proof
protected equipment, and connections to pressurized gas systems.
Maintenance and troubleshooting should be performed only by qualified
personnel.

The Sarasota SG901 consists of three instruments combined with a sample
system, which has various options and an optional electric heater or steam
enclosure heater mounted in a cabinet. These instruments are:

Thermo Scientific Sarasota FD900 density meter

PT100 thermometer element included in the density meter

Pressure transmitter
Note
Users should be familiar with operating the Sarasota CM515 and
Sarasota SG901 and with servicing the Sarasota FD900. Refer to the user
guides for each instrument (HB-CM515-DG01, HB-SG901, and
HB-ID/ FD900).

Note
It is assumed that the system is in service and has product running
through it.
