Progressive Industries Electrical Management System Instruction Manual

CAUTION

These instructions are intended to provide assistance with the installation of this product, and are not a substitute for a more comprehensive understandingof electrical systems. We strongly recommend that a certified electrician perform the installation of this product. Improper installation may void warranty.

Features

  • High/Low Voltage Protection: Whenever AC power lowers below 104 volts, or rises above 132 volts, the EMS automatically shuts down power to the RV. The EMS willmonitor the power and once the AC power rises above 104 volts, or drops below the 132 volt level the time delay indicator flashes for the preset time and then automatically restores power to the RV.
  • Time Delay for A/C Compressor: If AC power is interrupted or the EMS detects a fault condition, the built in time delay is activated. There are two settings on theEMS: one is 136 seconds (02:16), and the other is 15 seconds. Consult your air conditioner manual to see if it has a time delay built in. If so, use the 15 second delay, if not, use the 136-second delay. The factory setting is 15 seconds.
  • 3-Mode Surge Protection (EMS-LCHW30): This feature provides full surge protection L-N, L-G, and N-G. Total Joule rating is 1,790J and 44,000A surge current. Response time <1 Nano second.
  • 5-Mode Surge Protection (EMS-LCHW50): This feature provides full surge protection L-N, L-N, L-G, L-L, and N-G. Joule rating is 3,580J and 88,000A surge current. Response time <1 Nano second.
  • Surge Indicator: In the event of a power surge and the surge protector circuit is damaged within the EMS-L-N or L-G the digital error code will read E 10. This indicates the EMS needs to be serviced.
  • Reverse Polarity Protection: If AC power has a reverse polarity condition, the EMS will not allow power to the RV and the error code will read E 1.
  • Open Neutral Protection: If AC power has an open neutral, the display will not light and the EMS will not allow power to the RV.
  • Open Ground Protection: If AC power has an open ground condition, the EMS will read an error code of E 2, and power will not be allowed to the RV.
  • AC Frequency Protection: If AC power frequency deviates plus/minus 9 hertz from 60 cycles per second, the EMS will shut down AC power. An Error code of E 7 will be displayed when the frequency is high; and an Error code of E 8 will be displayed when frequency is low.
  • Accidental 240V Protection: If 240 volts is detected when plugging into AC power the EMS will NOT allow power to the RV. If this condition occurs while power isapplied to the RV, the EMS shuts off power instantly. The display will read the voltage and E 3 for the error. NEVER BYPASS THE EMS WHEN THIS OCCURS.
  • Display: Continuously scrolls the AC power information, including voltage, current, frequency, error codes and previous errors. Each reading is displayed for two (2) seconds.
  • Previous Error Code: Previous error code (PE) indicates what error occurred and why power was interrupted. To delete code, disconnect power from EMS.
  • By Pass: This switch is located on the remote display and allows the user to bypass the EMS in the event of failure, thus allowing AC power into the RV.This does not disable the surge protection portion of the EMS; however, all other features are disabled.
  • Modular Design: Replacement parts are designed for simple plug-and-play making repairs extremely user friendly.
  • Microprocessor Controlled: The computer and remote display are driven by stateof- the-art microprocessors that are programmed with software to drive the entireEMS unit.

Warnings

  • RV wiring is different than house wiring; in an RV, neutral and ground conductors are isolated whereas in a house they are bonded at the service panel. Therefore;never connect neutral and ground. The result will cause a ground fault condition, electric shock, and/or a fire hazard. This does not stop you from using a“generator plug” that ties together neutral and ground as this is perfectly safe.
  • Do not exceed the rating on the EMS for any reason. These devices are designed to be reduced down to 120V/15A and maintain full protection.
  • Do not modify the EMS in any way as this will void the warranty, compromise protection and could result in possible shock, and/or a fire hazard.
  • It is important to always check the pedestal power outlet for charring; this condition means the AC receptacle is providing a weak connection. Should this condition exists, DO NOT USE as it could result in possible melting of the RV power plug.
  • Progressive Industries recommends you have a certified electrician perform the installation of the EMS unit.
  • All AC power extension cords in conjunction with your EMS unit should be rated 10 gauge for 120V, 30A systems or 6 gauge for 240V, 50A systems and rated foroutdoor use to reduce the risk of electrical shock. We recommend the length not to exceed 20-25’. Small gauge cable will have a higher resistance and can result in voltage loss or an electrical fire.
  • Whenever servicing or installing the EMS, or any other AC powered device, make sure AC power is disconnected.
  • Never solder the ends of the wires you attach during installation, this includes any red, black and/or white wires.
  • Never plug the EMS into an inverter.

Installation Instructions Before Transfer Box

Visual Photo Library – LCHW50C: page 9 | LCHW30C: page 10Wiring Diagram – LCHW50C: page 11 | LCHW30C: page 11 For installation, in addition to the EMS Kit, you will need:

  • 6 mounting screws
  • In some cases you will need a jumper cable, length to be determined based on the placement of the EMS.
  • Always use #10 wire for the LCHW30C & #6 wire for the LCHW50C.
  1. Unplug RV from AC power and be sure generator is off.
  2. Determine a location for the EMS control box.
  3. Cut the RV power cord about three (3) inches greater than the distance from the junction box to the desired location of the EMS control box. Then strip back theouter insulation three (3) inches on input, and three (3) inches on output cable. See visual references on page 9.
  4. Strip back each conductor 3/8″ on both stripped ends and attach ring terminals to green ground wires. If this wire is a solid wire, do not use ring terminals. Loop the wire around the ground screw.
  5. Remove the lid from the EMS. Inside the unit will be a display, cable and pack of screws. Back off the six set screws from top of contactor (L1, L2, etc.).
  6. Take your long cable with the plug end and connect it to the input side by sliding through the wire restraint on the end of the EMS control box. Next connect the wires to the contactor by attaching black to L1, white to L2, red to L3, and green to ground screw on side of box. Torque down set screws and ground nut to secure connections.
  7. Take the short cable coming from the junction box by sliding it through the wire restraint output side of the EMS control box. Next slide the black wire through thecurrent sensor containing the green tape and connect to T1, then connect the white wire to T2. Next slide the red wire through the other sensor and attach to T3. Thearrow side off the sensor needs to face T1 and T3. Attach the green ground wire to the ground screw on side of box. Make sure the wire colors adjacent to each othermatch up. Torque down set screws and ground nut to secure connections.
  8. Double check all connections and make sure they are secure.
  9. Remove the two screws on contactor where marked L1, L2, etc. Next remove the top plastic plate with marketings. Examine inside ensuring there are no looseplastic pieces inside the contactor. If so, remove and re-install cover with two screws. See visual references on page 9.CAUTION If you break off a tab and do not remove it, this may stop the contactor from working and allow 240 volts in the RV.
  10.  Secure cable ends by tightening down strain reliefs ove the input and output wires. Do not over tighten as this could bit through the insulation and cause a short.
  11. Set time delay jumper on the circuit board. The factory setting is for 15 seconds. Remove jumper to set for 136 seconds (02:16). See Features Section on time delayto determine which to use.
  12. Plug in remote display and cable. (This cable is not a phone cable, but rather a data cable). NEVER PLUG IN DISPLAY WHILE RV POWER IS ON.
  13. Attach EMS lid with the six black machine screws provided.
  14. Mount the EMS control box.
  15. Installation is complete. Next, plug in and follow operating instructions.

Installation After Transfer Box for Protection from both Generator and AC Power

Visual Photo Library – LCHW50C: page 9 | LCHW30C: page 10 Wiring Diagram – LCHW50C: page 11 | LCHW30C: page 11For installation, in addition to the EMS Kit, you will need:

  • 4 mounting screws
  • In some cases you will need a jumper cable, length to be determined based on the placement of the EMS.
  • Always use #10 wire for LCHW30 models and #6 wire for LCHW50 models.
  • Surge & Electrical Protection units are for Recreational Vehicles (RV) only.
  1. Unplug RV from the AC power and be sure generator is off.
  2. Locate transfer switch box; determine where the EMS control box will be mounted.
  3. Measure the distance between the transfer switch and the control box and add one(1) foot. This is the length of cable that will be required for the installation. Make sure 6 gauge, 4 conductor cables are used.
  4. Remove lid from transfer box, disconnect and remove the output cable.
  5. Take jumper cable and strip back one end three (3) inches and the other end the same as the end removed from the transfer box. The cable removed from thetransfer box must have at least three (3) inches of the outer insulation removed. See visual references on page 9.
  6. Strip back all conductors 3/8″ and attach ring terminals to green ground wires (see visual references on page 9). If this wire is solid wire, do not use ring terminals. Loop the wire around the screw.
  7. Remove the lid from unit. Inside the unit will be a digital display, cable and pack of screws. Back off the six set screws from top of contactor (L1, L2, etc.).
  8. Take the jumper cable and connect it to the input side by sliding through the wire restraint on the end of the EMS control box and then connect the black wire to L1; white to L2; red to L3, green to ground screw. See visual references on page 9. Torque down set screws and ground nut to secure connections.
  9. The cable that came from the transfer box connects to the output side of the EMS control box in the same manner. Next slide the black wire through the currentsensor containing the green tape and connect to T1 and then connect the white wire to T2. Now slide the red wire through the other current sensor and attach toT3. The arrow side off the sensor needs to face T1 and T3. Next, attach the green ground wire to the ground screw on the side of box (see visual references on page
  10. Make sure the conductor’s colors match up across from each other. Torque down the set screws and ground nut to secure connections.
  11. Connect the loose end of the jumper cable to the transfer switch. See wiring diagram on transfer switch if needed.
  12. Double check all connections to ensure they are secure.
  13. Secure cable ends by tightening down strain reliefs over the input and output wires. Do not over tighten as this could bite through insulation and cause a short.
  14. Set time delay jumper on the circuit board. Factory setting is for 15 seconds. Remove jumper to change setting to 136 seconds (02:16). See Features Section on time delay to determine which to use. See visual references on page 9.
  15. Plug in digital remote and data cable (this cable is not a phone cable, but rather a data cable). NEVER PLUG IN THE DISPLAY WHILE RV POWER IS ON.
  16. Attach lid with the six black machine screws provided and attach transfer switch lid.
  17. Mount the EMS control box.
  18. Installation is complete. Next, plug in and follow operating instructions.

Operating Instructions

  1. Plug into A/C power.
  2. Digital display will read 888 for one second and then begin scrolling the voltage, amps, line frequency and error code, if any. In addition, the time delay light will flash while the EMS is going through its countdown and will stop when the unit engages (bottom right hand corner.) If delay light does not flash, a fault condition is present. Refer to the Error Code Chart (page 7) to determine the problem with the AC power.
  3. You may notice when first plugging in, the display may read E 9. This indicates the display has not received the data from the computer yet. Do not be alarmed, thisis normal. By the next scroll through, it should read E 0 if the AC power is normal.
  4. The digital display will give you a three digit number indicating your line voltage. Next, it will give you a “0A” reading indicating current (amps) Current(amps) will read zero until the time delay is complete (136 seconds or 15 seconds, depending on your settings). Then you will notice a number between 0 and 30.This number indicates how many amps the RV is drawing. Next, you will notice “60H”, indicating your line frequency. This number should remain fairly consistent;however, it may read plus/minus one or two. Lastly, note the E code. E 0 is normal and only when E 0 or E 10 is present will the delay light flash and allow power tothe RV. Refer to the Error code chart card that was provided or see Error Code Chart for additional information.
  5.  Verify the error code E 0 is displayed and set up is now complete.NOTE: If the wiring reads anything different than correct, the EMS will not turn on and we recommend you move to a different source of AC power or use your generator power. Also, if power is below 104 volts or above 132 volts, the EMS will not turn on, and we recommend using your generator power.

Error Code Chart

E 0 – Normal Operating ConditionE 1 – Reverse Polarity (hot and neutral wires reversed)E 2 – Open Ground (no ground wire connection)E 3 – Line 1 High Voltage (line voltage above 132V)E 4 – Line 1 Low Voltage (line voltage below 104V)E 5*- Line 2 Voltage High (line voltage above 132)E 6*- Line 2 Voltage Low (line voltage below 104 volts)E 7 – Line Frequency High (line frequency above 69 cycles per second)E 8 – Line Frequency Low (line frequency below 51 cycles per second)E 9 – Data Link Down (call technical support)E10 – Replace Surge Protector Module (call technical support)* Codes only apply to EMS-LCHW50 models

Note: If the EMS cuts the power to the RV it will show a PE code following the E code.This denotes the previous error or why the EMS shut down. Example: The EMS cuts power for low voltage on Line 1, and then the power is restored. The Error Code readsE 0, but the PE code reads PE 4 which tells the user low voltage was the reason for the EMS previously cutting power. This PE error code will be deleted when power isdisconnected from the EMS.

Accidental 240 volt Protection: Should this condition occur, the display will read 240 volts instead of displaying the voltage and the error code message will read E 3. ACpower will shut down instantly. DO NOT UNDER ANY CIRCUMSTANCES BYPASS THE EMS; OTHERWISE, THIS WILL RESULT IN SEVERE DAMAGE TO THE RV.

Troubleshooting Guide

Common installation mistakes:

  1. Check connections. Input is the plug side of the RV and black should be attached to L1, white to L2. Output (going to the RV) should match up. T1 is black, T2 white.The green ground get attached to the input and output on the side of the box.
  2.  Make sure the input wires are, in fact, the input wires. Connecting the output to the input of the EMS will cause the device to malfunction.
  3.  If the EMS is still not functioning at this point, follow instructions below prior to calling Progressive Industries Technical Support.

In order for the on-call Technician to help troubleshoot the problem(s) you are experiencing and render the best possible solution, it is necessary you be at yourRV when you place your call.

  1. If the display is illuminated and scrolling information, note the Error Code. If there is an Error code of 1-9, the device will interrupt the power. See Error Chart for definition of AC power problem. The device being off when an Error Code is present indicates the product is working properly and protecting your coach.
  2. If the display is illuminated and reading Error code E 0, and yet no power is present in the coach, please contact Technical Support. You must wait for the time delay light to stop flashing.
  3. If the display is not illuminated and power is in the coach there is a connection issue between the display and the main control box. Contact Technical Support.

Technical Support can only help if the above information is provided; therefore, please do not call until this information is obtained. Again, it is necessary for yourto be at the RV when you place your call. To recap…

  1. Are the connections correct?
  2. What is the Error Code message being displayed?
  3. Is the delay indicator flashing?
