Introduction
Thank you for purchasing the Atlas Sound ECS-6RMBIntelligent AC Power Sequencer. The ECS-6RMB(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 at the unit or remotely. Up to three ECS-6RMBunits can be daisy chained together with
independent trigger timing settings giving you a total of 18 sequence triggered outlets. The ECS-6RMBunit is the activation controller/
monitor portion of the system and requires a 120V AC Mains ECM (Electrical Controlled Module) for each triggered output. A variety of
remote ECM AC modules are available to meet different installation requirements which are discussed later in this manual.
The ECS-6RMBcan 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 ECS-6RMBhas 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 reset.
The ECS-6RMBalso features 6 sequenced independent relay contacts. The activation of the contacts works in parallel of the
corresponding ECM triggered outputs. Sequence activation can be done locally or remotely via a DC voltage or by a switch. There
are a variety of wall plates to choose from for remote activation. The ECS-KSW6 is ideally suited because of the remote channel
monitoring it provides. The ECS-KSW6 can be placed up to 1000ft away from the ECS-6RMB.
The ECS-6RMBincorporates an Emergency Power Down (EPD) feature. The EPD may be required by the local fire codes to pass site
inspection. When activated, this port turns off all channels at once.
To light your rack, the ECS-6RMBhas incorporated both front and rear XLR style sockets for the 16" gooseneck LED lamp. One AP-GNL18
lamp is included and an additional lamp can be purchased separately. LED lamps are far superior in longevity along with heat reduction when
compared to traditional incandescent lamps and the XLR base mounts are more secure than 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
ECS-6RMBto the ECM modules can be accomplished using any 5 conductor cable and can be placed up to 1000ft away. 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 ECS-6RMB, the ECM-RACEWY6 raceway can house up to six ECM-20 or
ECM-20M modules and six independent 20A AC 120V lines. For remote locations where single outlet turn On/Off and monitoring is
required the ECM-15SH (15A) and the ECM-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.
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 ECM-20M, ECM-15, and ECM-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 is also known as a surge. Surges are usually 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 are on the same power
leg of the building’s incoming AC.
