Page 6: General Information
General information Introduction With an automatic greasing system of Groeneveld all grease points of a vehicle or machine are greased automatically at the correct moment and with the correct amount of grease. Because greasing takes places while the vehicle or machine is in operation, the applied grease is spread optimally over the whole surface to be greased. -

Page 8: System With Pneumatic Piston Pump And Impulse Counter
Automatic Greasing System SingleLine System with pneumatic piston pump and impulse counter As a rule, trailers and semi-trailers are equipped with a pneumatic brake impulse counter and not with an SLT. This is because of a lack of a continuous electrical supply. The standard version of the brake impulse counter is pneumatically operated and uses the air signal from the service line which is usually connected to the number 4 position of the trailer relay valve. -

Page 18: Principle Of Operation
Automatic Greasing System SingleLine 3.3.2 Principle of operation The plunger pump (5) consists of six fixed plungers amid a ring duct. The six plungers are driven by the electric motor (9) through a mechanical transmission. In the channel between the ring duct and the outlet (6) of the pump unit, a pressure control valve (14) and an electrically operated return valve (10) have been built-in. -

Page 21: Adjusting The Greasing Interval Pulses
Automatic Greasing System SingleLine Adjusting the greasing interval pulses The greasing interval pulses can be adjusted with the rotary switch (Figure 4.1/3) at the SLT. Rotate the switch by using a suitable screwdriver to the desirable position. As a confirmation, a short audible beep sounds when rotating the switch in each position. -
Page 22: Test Button Functions
Automatic Greasing System SingleLine Turn the rotary switch of the pump time (Figure 4.1/1) to the correct position after determining the pumping time between the manually started greasing cycle and the on- pressure signal. The correct position: round the determined pumping time to the next full minute and add one minute (see example). -

Page 26: Impulse Counter
Automatic Greasing System SingleLine Impulse counter As a rule trailers and semi-trailers do not have a continuous electrical supply. For this reason an SLT cannot be used. In its place a brake impulse counter will be used. This may be electrically or pneumatically operated. -
Page 27: Setting The Number Of Brake Applications
Automatic Greasing System SingleLine activation is through pulses from the pneumatic system before the relay valve (or trailer reaction valve). The compressed air operates a piston, which in turn rotates the operating cam. After the preset number of pulses the operating cam opens the air valve through which compressed air passes to the pump. -
Page 28: Metering Units
Automatic Greasing System SingleLine Metering units Figure 6.1 Distribution block with metering units There are 11 metering unit types (1) available for the SingleLine system, each with a differing metered grease quantity. By careful selection of the type of metering unit each grease point can be provided with the right quantity of grease. -

Automatic Greasing System SingleLine Operating principle 6.2.1 Point of departure Figure 6.3 Metering unit in initial position Figure 6.3 illustrates a new metering unit. One that has not yet been filled with grease. Item (1) is the spacer, which determines the delivery of the metering unit (see paragraph 6.1). The metering units that are used in your greasing system may differ externally, or even internally, from the one illustrated here. -
Page 30: Phase B
Automatic Greasing System SingleLine 6.2.3 Phase B Figure 6.5 Metering unit in phase B When the pump stops and as the grease pressure in the primary line drops, spring (7) will push plunger (4) back to the left, closing off channel (1). O-ring (9) prevents grease from being sucked back from chamber (6). -

Automatic Greasing System SingleLine Other components Solenoid valve Figure 7.1 Solenoid valve The solenoid valve (Figure 7.1) between the air tank and the pneumatic pump (usually fitted to the pump) is a normally closed, free venting type. The valve is connected electrically by an M24 screw connector. -
Page 32: Pressure Switch
Automatic Greasing System SingleLine Pressure switch Figure 7.2 Pressure switch A pressure switch is included in the greasing system (in the primary line) to provide an alarm for too low a pressure in the system during the greasing cycle. This switch closes at a pressure of 40 bar, making a connection to earth. If this does not happen during the greasing cycle, because insufficient or no grease pressure is generated, an alarm will be given. -
Page 33: Reservoir
Automatic Greasing System SingleLine Reservoir Figure 7.3 Pneumatic pump The reservoir (2) is made from impact-resistant plastic that can withstand the influences of fluctuating temperatures. The reservoir can hold a quantity of grease that in most cases is sufficient for about 4 months, depending on the number of grease points. The minimum level (5 cm) is marked by a label (3) on the reservoir. -

NLGI 0-grease of EP quality and moreover must not contain graphite. Groeneveld has developed an EP grease in the NLGI class 0 especially for use in automatic greasing systems. This grease - Greenlube EP-0 - combines the best qualities of various types of greases. The use of Greenlube grease is recommended for the greasing system. -
Page 35: Maintenance
Automatic Greasing System SingleLine Maintenance General The maintenance of Groeneveld’s SingleLine greasing systems can be combined with the normal maintenance of the vehicle or machine. WARNING When cleaning the vehicle or machine with a high-pressure water/steam jet cleaner, the pump of the greasing system should not be directly exposed to the jet. -
