ETA-20SH AC Power Conditioning & Suppression Module IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage “ within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
ETA-20SH AC Power Conditioning & Suppression Module • • • • • • • • • • WARNING – WHEN THE DEVICE IS IN USE To prevent electric shock, do not remove the product cover as there are high voltage components inside. Refer all servicing to ETA Systems. Should any of the following irregularities occur during use, immediately switch off the power, disconnect the power cord from the AC outlet and contact ETA Systems.
ETA-20SH AC Power Conditioning & Suppression Module INTRODUCTION The ETA Systems ETA-20SH is a 120V 60Hz AC Electrical Control Module (ECM), 20A Single Housing (SH) Power Conditioner and AC Spike Suppressor that is designed to be used as a standalone unit or in conjunction with an ETA Systems Sequence controller ETAECS6RM or the ETA-ECS3 up to 1000' away.
ETA-20SH AC Power Conditioning & Suppression Module INTERNAL FEATURES OF THE ETA-20SH – PROTECTION BEHIND THE PANEL • EMI/RFI Filters ECM filters 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) produced by such items as electric motors or switching power supplies.
ETA-20SH AC Power Conditioning & Suppression Module FRONT PANEL 4 3 6 7 1 5 2 1. Trigger/Status Port Pin Identification All signals are of low voltage and current. DO NOT MISS WIRE or damage may occur. A. (+) requires a minimum of 5–24V DC to activate the module with 5mA of current. Note: The DCV can be supplied from any source. The EVS protection requires the ETA-ECS6RM for operation. B. G = Circuit Ground. Must be of the same circuit as the DCV source. C. V = AC Voltage Status Signal.
ETA-20SH AC Power Conditioning & Suppression Module ECM DATA WIRE AND DISTANCE The ETA-20SH is one of four different types of ECM Modules requiring the same interface connectivity to the ETA-ECS6RM. All ECM Modules can be interfaced with the ETA-ECS6RM. For connection between the ETA-ECS6RM and an ECM module, use a 5 conductor cable that is a minimum of 22 gauge wire. We suggest using CAT5 cable due to the common availability and low cost.
ETA-20SH AC Power Conditioning & Suppression Module ETA-ECS6RM SEQUENCER CONTROLLER INTERFACE WITH ETA-20SH To get maximum use of the ETA-20SH we suggest using the ETA-ECS6RM controller. When the two are interfaced the ETA-ECS6RM controller can not only remotely turn on the ETA-20SH but it can monitor the AC Mains Voltage and Current of the ETA-20SH.
ETA-20SH AC Power Conditioning & Suppression Module WIRING WITH AN ETA-ECS3 SEQUENCER CONTROLLER ECM DCV Trigger – T he ETA-ECS3 can handle 15A of current before the breaker opens. If 15A is not enough current to support your power requirements you can use the 24VDC trigger to activate an additional power outlet such as the ETA-20SH. This triggered 24VDC voltage works in conjunction with Sequence 3 timing section. Contact ETA Systems for AC outlet options.
ETA-20SH AC Power Conditioning & Suppression Module TROUBLESHOOTING THE ECM MODULE AS A STANDALONE UNIT Note: All troubleshooting should be done by a certified electrician. Issue 1: Incoming AC LED is not illuminated. Possible Cause #1: Incoming AC Mains circuit breaker has tripped due to excessive load. Action Needed: Possible Cause #2: Action Needed: heck the AC outlet that the ECM is plugged into for 120V AC voltage.
ETA-20SH AC Power Conditioning & Suppression Module TROUBLESHOOTING THE ECM MODULE WITH AN ETA-ECS3 Note: All troubleshooting should be done by a certified electrician. Issue 1: Incoming AC LED on the ECM is not illuminated. Possible Cause #1: Action Needed: Possible Cause #2: Action Needed: Incoming AC Mains circuit breaker has tripped due to excessive load. heck the AC outlet that the ETA-20SH is plugged into for 120V AC voltage.
ETA-20SH AC Power Conditioning & Suppression Module Issue 2: AC Fault LED is Flashing on the ECM. Possible Cause Although the Clamping Suppression circuit virtually assures protection from most transient voltage spikes and surges, nature has a way of occasionally creating electrical forces that are beyond the capabilities of any device to absorb without some degree of damage. In the rare instance that this occurs, the clamping circuit can be damaged during the suppression.
ETA-20SH AC Power Conditioning & Suppression Module AC POWER CORD RETAINER SYSTEM Your ETA Systems product comes with an AC Mains Power Cord Retainer System. This system prevents the power cord from being removed without the use of a screwdriver. Follow these steps for installation. Note: Installation of this product must be done by a certified electrician for a permanently connected apparatus provided neither with an all-pole mains switch nor an all-pole circuit breaker.
