BAL_2152_EP1_Central grease lubrication pump_0816_EN EDV-Nr. 1090200430
11.1.5. Optional equipment:
Grease level monitoring at the BEKA-troniX1 and the EP-tronic:
A capacitive proximity switch is installed into the reservoir for the
electronic control of the grease level in this reservoir. It sends a
signal as long as there is enough lubricant in the reservoir.
Technical data of the proximity switch:
Operating voltage: 10 to 60 V DC
Connection method: PNP-NO (normally open contact)
Max. current load: 250 mA
Protection class of the switch: IP 67
Ambient temperature range: 25° C to +70° C
Connection: 4-poles, M12x1 pluggable
The signal is evaluated by the control unit. When there is no signal for more
than 10 seconds, the control unit reports a malfunction (see signals on page 33) and
switches the pump off.
The pump starts to operate again automatically with refilling of the reservoir.
Pressure relief valve monitoring at the BEKA-troniX1 and the EP-tronic:
With a micro switch, which is mounted at the pressure relief valve of the
pump element, the operating pressure of the system can be monitored.
If the pressure in the lines exceeds 280 bar, the pressure relief valve
reacts.
The micro switch sends a signal to the control unit, which then switches
off the pump and indicates a malfunction (see signals on page 33;
terminal diagrams on page 15 and 19).
Technical data of the micro switch:
Operating voltage: 10 to 60 V DC
Contact type: 1 changeover contact
Max. current load: I = 1,7 A
Protection class of the switch: IP 67
Ambient temperature range: 25° C to +85° C
Connection: cable 0.5 m, bonded,
4-poles, M12x1 pluggable
After troubleshooting, you have to start the pump by pressing the button for intermediate
lubrication.
