10.2.9. Configuration of the APR-2200YALW smart level probes
10.3. Alarms.
Exceeding the transmitter correct operation limits or non functioning of some its components are signaled by
alarms. Menu of APC ... APR ... transmitters contains the following alarms: Hart Modem error, ADC error (
error of A /D converter ), EEPROM error, error of the oscillator, DS33 error (check the correctness of floating
point calculations). Errors reveal themselves by issuing in the transmitter current line: 22mA (high alarm) or 3.6
mA (low alarm), and signaling an error code on the display. Alarm current in the output transmitter line of 3.6
(low) or 22mA (high) can be set using the Report2 configuration program, or the currents alarm settings in
transmitter should be agreed with the producer. Exceeding of the basic pressure range of over 50% is
indicated on the transmitter display by code E0256 and alarm current in the measuring line; exceeding of the
measuring ranges in MID pressure transmitters is described in MID Appendix.
11. INSPECTIONS AND SPARE PARTS.
11.1. Periodic service
Periodic inspections should be made in accordance with the regulations to which the user is subject. During
inspection, the pressure connectors should be checked for loose connections and leaks, the electrical
connectors should be checked with regard to tightness and the state of the gaskets, cable glands, and the
diaphragm seals should be checked for tarnishing and corrosion.
Check the characteristic conversion curve by following the procedures for “Calibration” and, where appropriate,
“Configuration”.
