The MEMOLUB
®
24VDC-PLC Controlled lubricator has
a unique design utilizing a Power-Through Memo which
contains the electrical connections needed to power the
unit. This gives the user the ability to quickly remove the
lubricator for fast lubricant cartridge change-out while
avoiding disconnecting the electrical connections. A 5-
foot extension cable on the Power-Through Memo is
connected to a PLC-controlled power supply. Because
the PLC program controls the frequency of lubrication output cycles, they may be
based upon elapsed clock hours, machine cycles, a count of parts produced, or other
desired criteria. Further control is provided by adjusting the volume of lubricant
ejected on each cycle. A set of 8 special stroke-limiting washers are supplied with each
lubricator. When the Power-Through Memo is used without washers (yielding full
piston stroke), the output volume at each stroke is 0.635cc. For each washer (including
the "C"-shaped lock washer) inserted into the brass adapter of the Power-Through
Memo, the output volume is decreased by 0.04cc per stroke.
(Note: The lock washer
should always be inserted last to hold the others in place.) Please refer to the Installation
Instructions in the Appendix.
Output per spacer washers:
0 = 0.63cc/stroke 3 = 0.51cc/stroke 6 = 0.39cc/stroke
1 = 0.59cc/stroke 4 = 0.47cc/stroke 7 = 0.35cc/stroke
2 = 0.55cc/stroke 5 = 0.43cc/stroke 8 = 0.31cc/stroke

5.1 Tubing
Only tubes rated at a minimum working pressure of 580psi should be used. Polyamide
tubes (air) are not suitable for use with the MEMOLUB
®
HPS. Keep in mind that a
tube’s pressure resistance diminishes with increased temperature. The following table lists
the appropriate tubing for a particular ambient temperature range:
