OPERATING INSTRUCTIONS RH 40 F Inspection and servicing Greasing cycle The greasing cycle is initiated by a electronic unit. The duration of a single cycle is controlled by the check-back signal from the sensors in the greasing circuit.
Presetting the pause duration The pause duration is preset with jumper (21, Fig. 3-101:) and rotary switch (22). Jumper (21) placed over contact pins on the left and in the middle: presetting of minutes. Do not change the setting
The optimal adjustment of the pause duration is attained when an increasing ring of grease forms at the greasing (friction) points. If one of the greasing points shows a different behaviour, it is not being supplied with sufficient grease. In this case, the pause duration must be adapted accordingly. Indicators Diode (23, Fig. 7) lights up when the power supply in on. Diode (24) lights up in the event of malfunctions (code flashing sequence see table in Fig. 8). The control panel indicator "Lubrication" in the driver›s cab flashes in the same sequence. A = Drive motor defective
Rotary switch (22) is used to preset 15 time ranges 1 thru and A thru F.
B = Malfunction of lubricating circuit 1 C = Malfunction of lubricating circuit 2 D = Malfunction of lubricating circuits 1 and 2 E = Container empty (Optional) F = Pump running indicator extinguished during greasing pauses
Fig. 3-101:
Rotary switch (22) is set to range "1". The corresponding pause duration is the 4 minutes. If rotorary switch (22) is set to range "2", the pause duration will 8 minutes. In range "3", the duration is 12 minutes. Increasing the range by one step of the switch prolongs the pause duration by another 4 minutes. Set the pause duration at first to 4 minutes. If required, the pause can be prolonged later on.
