Indirect stop: occurs when the pressure rises to the pre-set Indirect stop setpoint (= setpoint plus Indirect
stop level). The motor will decelerate to minimum speed and the compressor will switch to unloaded
condition.
Direct stop: occurs when the compressor runs at a speed between minimum and maximum and the net
pressure rises above the direct stop setpoint (= setpoint plus Direct stop level).
Both settings (Indirect stop level and Direct stop level) are programmable, see section Programmable
settings.
