Lowell SEQ-4 Quick Start Manual

Includes power supply
with NEMA 1-15 plug
and three adaptors
Compact low voltage four step sequencer model SEQ-4 is
designed to work with a single external switch and low voltage
remote power controls (RPCs) to provide time-delayed activation
and deactivation of AC powered equipment on site or at remote
locations.
Note: This sequencer is for use with compatible components that feature classic
connections. It is not for use with devices that feature pass-through connections.
FEATURES:
• Power Requirement: 100-240VAC 12W
• Activation Trigger: Sequencing is initiated by a remote
external switch (order separately).
– The circuitry is designed to operate using a single remote
SPST switch with maintained contact closure.
– The sequencer can accept mulltiple switches if they have
momentary contact closure and Lowell MSM2 module is
connected between the sequencer and switches.
• Four (4) Step Delay:
– Time-delayed closure circuits activate in sequential order
(1, 2, 3, 4) and deactivate in reverse order.
– The delay between steps can be adjusted via an externally
accessible trimpot (0.5-10 seconds).
– LEDs provide visual status of the activation sequence.
– Includes auxiliary 24VDC output (300mA max.) for use with
remote indicators, if needed.
• Compact Chassis: 7" x 3.28" x 1.69" (4 lbs.) steel chassis
with black powder epoxy finish and mounting holes.
– Unit can be installed in a remote location or rack panel (2U).
– Operational diagram printed on top of chassis aids system
set-up.
• Country of Origin: Made in U.S.A. with global components

model SEQ-4, which shall feature barrier strip terminals for
connection to a single external remote switch with maintained
contact closure (or multiple remote switches with momentary
closure and Lowell MSM2 module wired between the
sequencer and switches). The sequencer shall connect to
external remote power controls (RPCs) to activate remote
equipment in four steps with an adjustable time delay between
each step. It shall activate RPCs in order (1, 2, 3, 4) and
deactivate them in reverse order. The sequencer shall feature
a steel chassis with mounting holes, black powder epoxy
finish, and overall dimensions of 7" x 3.28" x 1.69". It shall
be made in the USA with global components, and include a UL
Listed power supply with NEMA 1-15 plug and three adaptors
(Schuko CEE 7/16, BS1362, AS3112). External switches and
remote power controls are required for sequencer use and
shall be ordered separately.
