Stream detection operation time: Shall be OFF state during action time, and input of a stream
detection switch perceives.( If it is 0 seconds, do not perceive)
2) Outlet temp freeze: A trip function runs hereafter the freezing temperature that exit temperature is
excessive.
3) Oil flow error fault
Oil flow delay: Start for perceiving after delay time since a freezer was driven a detection of
an oil stream switch. (( Be always detections if set up in 0 seconds)
Oil flow operation time: Shall be OFF state during action time, and input of an oil stream
switch perceives. (If it is 0 seconds, do not perceive)
4) Lo press error fault
Lo press sensing delay: Start for perceiving after delay time since a freezer was driven a
detection of a low pressure switch. (Be always detections if we set up in 0 seconds)
Lo press sensing time: Shall be OFF state during action time, and input of a low pressure
switch perceives (If it is 0 seconds, do not perceive)
5) Oil level error fault
Oil level delay time: Start for perceiving after delay time since a freezer was driven a
detection of an oil level switch.( Be always detections if we set up in 0 seconds)
Oil level operation time: Shall be OFF state during action time, and input of an oil level switch
perceives. (If it is 0 seconds, do not perceive)
6) Condensor fault func.: If it is an air cooling formula, select whether or not there is by condensor
Fan alarm use.
