Erractic pressures
in SEQUENCE

The sequencing system transmits low-level signals between units to communicate
pressures. Units must be properly grounded to a good ground system, The
sequencing system transmits low-level signals between units to communicate
pressures. Units must be properly grounded to a good ground system, The
communications cable should use only appropriate quality cable, and the cable
should be run in its own conduit. (V4.xx only)
Compressor
cycles rapidly in
SEQUENCE
mode only
In the sequence mode, the operating system requires all compressors be piped
directly to the receiver, such that all transducers sense the same pressure. Check
valves or restrictions between compressors and the storage will cause system
instability. Run units in AUTOMATIC mode until the system is corrected. (V4.xx
only)
Error in displayed
pressure or
"CHECK
XDUCER" while
zeroing
Pressure measurement errors are almost always the result of poor zero
adjustment. This must be done after replacement of a controller or a transducer.
The proper display with all pressure removed is 0 +1 psig. The adjustment
procedure will prevent large zeroing errors, and recommend that the transducers
be checked.
