The REM-1E Digital Display Controller serves as
either a pump remote control station or a
proportional pump controller (4-20 mA input) or
both. The REM-1E can be used to vary the output of
any Liquid Metronics (LMI) Series AA7, A7, B7, or C7
metering pump when those pumps are placed in
the external mode. This is truly a "plug-'n-play"
accessory. A simple connection of 4-conductor
cable from the control unit to the external input
jack of the LMI pump is all that is required for start-
up. Power is supplied by a 15 VDC source from the
LMI pump through the 4-conductor cable.
The controller output, in the form of contact
closures of 80 ms duration, triggers the LMI pump.
In the internal mode, output is 0-100 strokes-per-
hour (sph) or 0-100 strokes-per-minute (spm). A
touch of the pressure-sensitive keys varies the

output, which is displayed in large, easy-to-read
LCD digital format. Changes left for longer than 5
seconds are saved in non-volatile memory. In the
external mode, output is from 0-100 sph or 0-100
spm directly proportional to the 4-20 mA analog
input signal. Ten feet of 3-conductor cable and
connectors are supplied as standard for the 4-20
mA application. Zero and span adjustments may be
done through the outside keys of the controller.
In the "OFF" position, the 15 VDC power source will
be present, but the controller output will be zero.
