All A non-command shutdown of the fixed speed compressor
occurred. The controller detected that the input was not
proven. This could be a result from the following: High
pressure cutout or any fault from the compressor
protection module.
All The fixed speed compressor failed to start when
commanded. The controller detected that the input was
not proven. This is could be the result of a compressor
protection module fault.
All The fixed speed compressor failed to prove off when
commanded to shut down or the compressor proving
input was proven when the compressor was not
commanded to run. If a compressor proving input is
reporting that the compressor is still running 6 seconds
after the Symbio800 has Commanded it Off; then, this
warning diagnostic shall be active and the circuit will be
shutdown. If the compressor proves, but the Symbio800
has not Commanded it On, then it is assumed that a
compressor has started un-commanded. When the
compressor proving input is proven for more than 6
seconds the diagnostic will be generated and the circuit
will be shutdown.
Note: Possible future enhancement not included in Release 1.
If implemented the severity will have to go to Warning.
The following Special action will also be performed:
• The effected compressor will be continually
commanded off and a normal stop shall be commanded
to the Unit
• All other compressors on the effected circuit remain off
or will be shutdown
• If there is another circuit it will remain off or be will be
shutdown
• Heating will not be allowed to run
• The controller shall continue to run Head Pressure and
Superheat control and the supply fan shall continue to
run
All Emergency stop feedback input has Opened. Time to trip
from input opening to unit stop shall be 0.1 to 1.0
seconds.
