9. APC-2000ALW in MID application. Alarms
Pressure transmitters 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 this User Manual
DTR.APC.APR.ALW.03(ENG).
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:
converter HART / RS-232 or other for example HART/USB Converter;
PC with Windows XP or higher, with at least 512 MB of RAM;
Report 2 APLISENS software.
A computer with a converter must be connected to the transmitter as shown in Figure 2a or 2c for the load
resistance Ro <240 , see User's Manual DTR.APC.APR.ALW.03(ENG) p.16. Drawings. After starting Report 2
program read data from the transmitter. Installation parameters and current parameters of the transmitter 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.
