The following menus show temperature probe information. These readings are more difficult to utilize, as the RTD probes are resistance devices, whose signals are processed before input to the A/D converter. Of more interest will be the OFFSET values. If these values are off by a large amount or show a variance in one RTD, a potential fault could be indicated.

This menu is used to cancel the flag set by the detection of residual pressure during blowdown when the compressor unloads. The unloaded pressure in the piping should be below 5 psig during the unload period. If not, a flag will be set, and the HIGH DISCHARGE PRESSURE indicator will be blinking at 1 second intervals if the STAGE 2 blowdown fails to reach the 5 psig trip point. Likewise, the HIGH INTERSTAGE PRESSURE light will blink when the interstage does not reach the 5 psig point. If the setting is cleared while the

indicator is lit, the indicator will remain lit.

Press ENTER to return to the Maintenance Menus.
