The MEMOLUB® EPS is ideally suited to applications in which
machinery is intermittently or infrequently used. It provides the
control needed to insure proper lubrication during periods of
operation while avoiding the problem of over lubrication.
An external 4.5 VDC power source is connected to the 12 inch
cable extending from the bottom of the MEMOLUB®. A battery
pack is not required. Extension lead wires and connectors are
available.
The MEMOLUB® EPS can mounted directly on the bearing point
or remote from the bearing using pipe or flexible tubing. It may
also be used as a Multi-Point System lubricating from 2 to 12
lube points. The EPS is available in any of the three
MEMOLUB® sizes.
Control of the lubrication injection cycles occurs in one of two ways.
Controlled lubrication with a 4.5VDC External Power Supply
• The MEMOLUB® EPS is periodically supplied with 4.5 VDC power by a PLC under program
control. Lubrication output cycles of the MEMOLUB® can be based upon hours of machine
operation, a count of machine cycles or any other desired criteria.
• The MEMOLUB® EPS operates under its own
program control
. Constant 4.5 VDC power is
supplied by a transformer during periods of machine operation. The MEMOLUB® program
controls the frequency of lubricant output cycles.
•
A manual switch can be used to turn on 110 VAC power to a 4.5 VDC output transformer during machine
operation OR,
•
A relay associated with the main power switch of the machine can supply 110 VAC power to a 4.5 VDC output
transformer during periods of machine operation.
The volume of lubricant ejected on each output cycle is programmed in the standard manner using the MEMO fitting
and Stroke Limiting washers. (Refer to Lubricant Output Programming Chart)
