9.6 Additional function of line rupture monitoring at distributor
The integrated control unit PICO-tronic can electronically
evaluate the line rupture monitoring at the progressive
distributor.
Micro switches are installed at the progressive distributor
MX-F. They send signals to the control unit as long as there
isenough pressurein the line.
If the line pressure drops, e.g. because the machine with
installed lubrication system has been switched off during the
night,the microswitches stop sendingthe signal.
If the machine and lubrication system is switched on again, the pump start to build up the pressure in the line. If this is not
possible after the set number of start cycles (standard 2) and following set monitoring time (standard 1 min.), because for
example, a line is ruptured or leaky, the control unit sends a malfunction signal (see 12.3 signals of the integrated control
unitPICO-tronic).The pumpcontinues operating tolubricate the lubepoints thatareconnected atthe faultless lines.
The micro switches are connected in row. If a micro switch does not activate the signal, the signal for the control unit is
missing.If thepressure is buildup again afterthe repair, theerror isautomaticallyreset.
Theconnection atthe control unitis done viathe leftHirschman plug atthe control unithousing ofthepump (seefig. 28).
Ifthe additionalfunction „line rupturemonitoring“ is used,the followingfunctions are notavailable:
· Operating mode cyclecontrol pulse-dependent
· Monitoring of pressurein linesystem (system pressuremonitoring)

Signals:
· No pulse cyclewas receivedwhile the monitoringtime
· The distributor receivedno pulseduring the monitoringtime.
· The pump motorsensor receivedno speed pulseduring the monitoringtime.
· Reservoir is empty.
· System pressure toohigh (system).
· Operating pressure inthe lineis not reached(line rupture monitoring).
· The lubrication duringcycle durationcan not befinished (lubrication deficit).
· Error „memory /CPU“ isavailable.
