Berchtold / 11.07.01ØNormal cyl. lubrication:Load dependent adjustment of electric motor speed.ØEmergency lubrication:Electric motor running at nominal, constant speed.ØConsequences for emergency lubrication:- Increased specific feed rate at part load.- Same feed rate as in normal mode at 100% load only with pump speed factor = 1!- Pump speed factor > 1: Feed rate at 100% load is lower compared to normal mode.- Pump speed factor < 1: Feed rate at 100% load is higher compared to normal mode.- Em. lubrication needs careful attention and adjusting of setting screws! CLU-3 Control Modes CLU3WCH / Licensing / 4067 / M. Berchtold / 11.07.01ØThe feed rate can be adjusted by changing the so called pump speed factor in the RC system. The parameter should be within 0.85 and 1.15. By changing the pump speed factor, the feed rate can be adjusted in very small steps.Only the total amount can be adjusted. It is not possible to adjust the upper / lower level or single units ØThe other possibility is to adjust the setting screws on the lubricator. Here the upper or lower lubrication level can be adjusted separately. Also single cylinders can be adjusted separately.The feed rate will change in big steps.

Berchtold / 11.07.01ØThe normal power supply, as well as the emergency power supply for the lubricator are connected to the CLU3 control box.ØThe frequency converter converts the 4-20mA (0-160% Lubrication Signal) signal from the Remote Control system to a speed signal (0-2880rpm ) for the E-Motor on the lubricator.ØAll parameters in the frequency converter are already set during shop test.ØIn case of a replacement of the converter later in service, the parameters have to be set again as per enclosed parameter list.ØOn the Frequency converter the output frequency as well as speed of the electric motor is indicated. The speed of the electric motor can be seen by changing to parameter 0102.Frequency converterCLU3 Control BoxCLU3WCH / Licensing / 4067 / M. Berchtold / 11.07.01Frequency conveter para.
