Definition of the unit behavior after switching of external alarm contact
The HP Sw Test shuts off all fans while compressor is running in order to raise condenser pressure until tripping
of the high pressure switches. Beware that in case of high pressure switch failure the safety valves will trip and
hot refrigerant will be ejected at high pressure!
Once tripped, the software will get back to normal operation. However, the alarm will not be reset until the high
pressure switches are manually reset through the button included in the switch.
