7.5.1 Operating mode: MANUAL VERSION
The Bravo Manual version does not have any settable feature as there is no local controller. You should arrange to control the pump
ON/OFF with a host system that activates the pump as required and monitors the lubrication system, including checking level switch
and cycle switch when installed.

● Pause and lubrication cycle determined by external
impulse [P.Cou ≥ 0; C.Cou ≥ 1]
● During lubrication, cycle sensor monitored to confirm
correct lubrication [C.Min ≥ 1]
● C.Min determines how many min. seconds to allow for the cycle
sensor.
● Lubrication cycle is suspended if external impulse not
detected within user preset time [S.Min ≥ 1]
