Will occur if the remote start/stop option is enabled, the
remote stop button remains open and either start button

sensor failure message shall follow the following format:
3APT Failure��
Emergency Stop
Xe-70M On-Screen Text: Emergency Stop
This will occur when the EMERGENCY STOP button is
engaged��
High Sump Pressure
Xe-70M On-Screen Text: High Sump Pres
This will occur if the compressor is running loaded for at
least 8 seconds, and any one of the 3 following conditions
exist�� (1) The sump pressure is above the rated pressure
by 35 psi�� (2) The separator pressure drop is measured to
be more than 25 psi and the package discharge pressure
at least equal to the minimum online set point value�� (3)
The sump pressure is above 165 psi if the rated pressure is
less than 190 psi or the sump pressure is above 220 if the
