9. APC-2000ALW in MID application. Alarms
Pressure transducers in MID version alarm exceeding of the limits of measuring ranges (lower and upper) by
flag in the output signal Hart, and information, respectively "o u E r" or "u n d E r" in place of the first process
variable on a transmitter display. Other alarms work as at p.10.3 Manual
10. Verify of the pressure transmitter in its workplace.
To verify the correct functioning of the transmitter at its workplace should be used a HART system diagnostic
tool implemented to transmitter . For this purpose is need:
- HART modem / RS-232 or other for example HART / USB / Bluetooth;
- PC with Windows XP or higher, with at least 512 MB of RAM;
- Report 2 APLISENS software.
A computer with a modem must be connected to the transmitter as shown in Figure 2a or 2c for the load
resistance Ro <250 Ω, see User's Manual p.15. Drawings. After starting Report 2 program read data from the
transmitter. Installation parameters and current parameters of the transducer are recorded in the tabs of the
Report 2 And so in:
- Identification tab - read the identity data of the transmitter;
- Basic parameters tab - check the measuring range, pressure unit and time constant;
- Process Variables tab - check the current parameters of the transmitter measuring;
- Write protection tab - check the setting of current lock before entries;
- Transmitter Status tab - check the current status of the transmitter, its analog and digital outputs status with
the marked exceeded errors of measuring range, or errors of particular blocks of the transmitter if they would
existed.
Transmitter verify in the workplace should make a worker who is trained in the handling of measuring
electrical installations in explosive environments.
11. APC-2000ALW in MID application. Repair, calibration.
Transmitters repair should be performed by the manufacturer, or the manufacturer's authorized repair shops.
The procedures of handling after transmitters repairs should be in accordance to the provisions of the country
where transmitters are operating.
