Design

The example applies to a Dual Line centralized

lubrication system with two zones (zone 1/

zone 2 (line 1/line 2)).

It is composed of the main components

Dual Line pump (1) with pressure-regulat-

ing valve (2), two electrical 4/3 zone valves

(5/6) (EMO3), and Dual Line feeders (13).

A main line (3) with a pressure switch (4) is

flanged to the pump and switches off the

pump once the set maximum pressure is

reached. The main line (3) connects the

pump outlet with the two electrical 4/3 re-

versing valves for zone 1 (5) and zone 2 (6).

A PT pressure switch (7 to 10) for pressure

monitoring (change-over pressure) is fit-

ted at the end of each line ahead of the last

feeder. Further, a piston detector is fitted on

the last feeders (11/12) to monitor the lu-

brication cycles. Chapter 3 contains a

general functional description.

IMPORTANT NOTE

Only one operating voltage (24 VDC or 230

VAC) can be connected to terminal strip 4.1

or 4.2. Do not operate two different voltages

within a terminal strip!
