The set program, the lubrication duration and the cycle duration are shown alternately in the display of the device when the device is
in operation (see chapter 15.1 “Signal displays of the control”).
The settings can be changed at any time (see chapter 11. “Control”).
* Lubrication and cycle duration are displayed at the same time.
10. Functional description
The DC motor sets the eccentric via a gear into a rotating motion, whereby the stroke movement of the pump element piston is carried
out. The suction and the pressure stroke forcedly arise due to the stroke movement of the piston. The lubricant is sucked out of the
cartridge during the suction stroke and is supplied into the connected line at the subsequent pressure stroke.
The device can be operated with a connection voltage of 12 V and 24 V. The speed and delivery rate remain constant, independent
of the connection voltage.
The device has a level prewarning. The control determines the operating time of the device until the emptying of the cartridge by the
set cartridge size. With a residual quantity in the cartridge of approx. 10 – 30 %, the control shows the error LO. Despite this error, the
device continues to operate. The level prewarning must be reset after each cartridge change (see chapter 11.5 “Level prewarning”).
10.1 Pressure limiting valve
A pressure limiting valve is located on the pump element. It is preset to 290 bar and protects the device from being damaged by too
high pressure. If the pressure in the device exceeds the set value, the pressure limiting valve opens and the lubricant escapes at the
top of the valve.
Lubricant can leak out at the pressure limiting valve under high pressure (> 290 bar)!
Wear corresponding personal equipment (e.g. safety goggles) and keep out of the direct area of the pressure limiting
valve when there is a malfunction at the device.
Only work at the device when it is in a disconnected and pressureless state!
