INTRODUCTION
Thank you for purchasing the ETA Systems ETA-ECS6RM Intelligent AC Power Sequencer. The ETA-ECS6RM (Electrical Controller
Sequencer with Six Timing Sections with Remote Monitoring) modular system has been designed to meet most installation
requirements for AC power distribution, equipment power conditioning and surge suppression protection. The compact 1RU unit
features six sequential timing sections that can be activated via the unit, or remotely. Up to three ETA-ECS6RM units can be daisy
chained together with independent trigger timing settings giving you a total of 18 sequence triggered outlets. The ETA-ECS6RM unit
is the activation controller/monitor portion of the system and requires a 120V AC Mains ECM (Electrical Controlled Module) module for
each triggered output. A variety of remote ECM AC modules are available to meet different installation requirements.
The ETA-ECS6RM can also monitor up to six independent 20A AC main lines, both voltage and current readings can be viewed via the
laboratory grade meters on the front panel. The ETA-ECS6RM has built in intelligence that monitors the AC lines and will inform you of
potentially damaging voltages. If the AC Mains voltage is between 101VAC and 107VAC or 128VAC and 132VAC the display will flash
an error code indicating a potential fault has occurred and sensitive equipment should be checked. If an extreme voltage swing occurs
above 128VAC or below 101VAC, the Extreme Voltage Shutdown (EVS) protection circuit will automatically turn all remote ECM
modules Off until the system is manually reset. The EVS feature can be defeated if required.
The ETA-ECS6RM also features 6 sequenced independent relay contacts. The activation of the contacts work in parallel of the
corresponding ECM triggered outputs. Activation can be done via the Front panel momentary switch, RMT V input (5-24VDC), External
switch or via the optional Remote ECS-KSW6 key switch. The ECS-KSW6 can be placed up to 1000 ft away from the ETA-ECS6RM and
will also indicate if an ECM is activated or if a fault condition has occurred to one or all six channels.
To light your rack, the ETA-ECS6RM has incorporated both front and rear XLR style sockets for the 16" gooseneck LED lamp. One Atlas
Power AP-GNL18 lamp is included and a second lamp can be purchased separately from ETA Systems. LED lamps are far superior in
longevity along with heat reduction when compared to traditional incandescent lamps and the XLR base mounts are also superior to
the commonly used BNC type base.
The ECM modules have been designed to be flexible to meet a variety of AC power management requirements. The mating of the
ETA-ECS6RM to the ECM modules can be accomplished using any 5 conductor cable and can be placed up to 1000 ft away from each
other. Each ECM module has an input DC voltage trigger of 5VDC, plus three low voltage data port connections for AC Mains
monitoring. If AC outlets are required to be placed within the same rack as the ETA-ECS6RM, the ECM-RACEWY6 raceway can house
up to six ETA-ECM20 or ETA-ECM20M modules and six independent 20A AC 120V lines. For remote locations where single outlet turn
On/Off and monitoring are required the ETA-15SH (15A) and the ETA-20SH (20A) can be a perfect fit. All ECM modules offer different
and unique packaging designs and mounting options to assure they meet job requirements.
Features of the ECM modules vary allowing the customer to choose what is best for their installation, but all ECM modules feature AC
spike suppression. AC Spikes, or Transients, are commonly caused by utility power plant grid switchovers. The amount of energy that
can be injected into the power system can be immense with voltages reaching 6kV or amperage peaks of 3000A. These spikes are
very fast and usually only last for a very short period of time. To protect against this potential problem incoming AC Mains have special
suppression circuitry to eliminate the unwanted energy. This circuitry is very fast and can suppress unwanted energy within a
nanosecond, while sustaining the suppression for up to 2 milliseconds, thus ensuring virtually trouble free protection. High and Low
AC Main line voltages are another major contributor to equipment failures. The ECM modules support EVS circuitry which enables the
module to be shut Off during Low and High AC Line conditions.
The ETA-ECM20M, ETA-15SH and ETA-20SH, also feature noise filtering for unwanted Radio Frequency Interference (RFI) that is
commonly introduced into the AC lines by nearby radio transmitters or wireless products. EMI filters are incorporated to reduce noise
from Electromagnetic Interference (EMI) generated by items such as electric motors and switching power supplies. The benefit of
these filters can be seen on video products or audibly by reducing static pops and external signal interference.
High line can also be known as surges. Surges usually are a slower steady state rise in voltages ranging from 128VAC and up. They can
be caused from fluctuations in the utility company's power lines or industrial equipment turning On and Off and on the same power leg
of the building's incoming AC.
Low line is also known as brownouts. This happens when the AC Mains drops below 107VAC. Most of the time it is caused by the
utility company not being able to supply enough power during heavy utility consumption time periods, such as heat waves. Another
factor would be from voltage drops in AC lines due to long transmissions. The ETA-ECS6RM will inform you if any of these conditions
occur. Extreme variances in Unstable AC Mains voltage are one of the main reasons for equipment failure.
The ETA-ECS6RM offers Intelligent Sequenced Power Management control, making it the most flexible, effective power management
protection system on the market today.
