Ask a question I kept the oe stereo so I hooked up the amp with the speaker level inputs. Everything worked fine for a couple of months. I fold down the rear seats so it can get cooled if it gets hot. Now I noticed no bass coming from the trunk so I saw that as soon as I turn stereo on, the amp goes into protection mode. I rechecked my power, ground, and remote wires and they are ok. What I notice is that if I disconnect the speaker level inputs, the protection light goes out and the power light turns on. As soon as I connect it back, it goes into protection mode again. This manual comes under the category Receivers and has been rated by 1 people with an average of a 10.

Not approved for use in explosive atmosphere locations.All of the information is provided for the proper operation and troubleshooting of the BOSS Series. Pay close attention to any safety warnings, and save these instructions for further technical and informational reference. Last updated on April 7, 2018 Combustible materials and fumes in confined work areas can ignite and explode. To help prevent explosion, fire and electric shock: Tighten or replace loose or worn or damaged parts immediately. This will protect you from serious injury including but not limited to: eye injury, inhalation of toxic fumes, and loss of hearing. To avoid burns: This product is commonly referred to as ISO or A side. When ISO is exposed to moisture, it begins to react by forming small crystals that become suspended in the fluid. After prolonged exposure, a film is created on the surface of the fluid and the ISO begins to thicken into a gel. This adversely affects the performance of the ISO as well as puts added stress on the wetted parts of the plural component system.

Failure to properly circulate material may cause permanent damage to hose, supply lines, recirculating lines, and machine! Do NOT turn on switch to pressure up air motor. Use only transfer pumps to circulate material through system. Relays receive a “charge” from the Controllers when heat is required then sends power to the A-side and B-side Heaters. NOTE: The Hose Heat Relay is in the base of the unit All of the information is included for user safety and avoiding possible breakdowns from the incorrect use of the BOSS Series Proportioner. Only mix if resin contains water as the blowing agent. A purple sensor wire will protrude from the insulation on the hose. Cut the end of the purple sensor wire that runs the length of the hose and connect it to the short wire coming out of hose insulation. Pull the scuff jacket back to the end of hose and tape. Check for leaks. If there are not leaks, wrap hose and electrical connections to prevent from damage. Use the chart below to determine the lead that is appropriate for desired hose length. This lead should be connected to the end of the fuse facing you. If it is not connected, connect it now. (Leave this panel off for now) The AC amps should read between 38 and 55. If the amperage is higher than 55, connect the next lowest voltage lead wire from the transformer to the fuse block in bottom of machine. If it is below 38, connect the next highest voltage lead. (See Figure 10 above for voltage connection guidelines) If using a foam that contains water as the blowing agent, it is recommended to stir the B component for 20-30 minutes before spraying. Open fluid valves A and B until clean, air-free fluid comes from valves. The numbers that appear on the controllers are the actual temperatures. This will increase the target temperature. For best results, set according to the chemical manufacturer’s recommended temperature. The bottom two (A and B side pre-heater) controllers should be set in an identical manner.

The indicator lights and the LED indicator lights to the left of controller indicate pre-heaters are heating. Allow 20-30 minutes to heat up to working temperatures. Skin Injection warning?) Do not allow the pressures of the A and B side to have a variance of more than 200 psi. If this occurs, material may “crossover” at the gun. Open the air valve at gun Adjust fluid pressure as needed Adjust temperature and pressure for desired spray pattern See manufacturer for further information. Refer to spray gun literature for shutdown and cleaning procedures. It is recommended to lower the system pressure to a minimum of 400 psi. The pump needs to be “parked” in the down position to avoid ISO hardening on the A-side shaft. Pressure may also be bled off by spraying the gun, or through the side blocks if they are not attached to the gun, by opening the ball valve. The B-side pump should also be lubed initially, but isn’t as critical as the A-side and won’t harden. Do not use water. This light indicates the controller is sending a message to activate the hose heater. The two red wires that come out of the front of the proportioner (circled in yellow on photo) provide heat to the hose. These two wires run the length of the hose and are connected to the 10-foot whip. This purple wire contains three wires under the purple insulation (purple, red and uninsulated) and measures the hose temperature and reports it back to the Hose Heat Controller. It is best to view hose heat as a material temperature maintainer and not as a material heater. It is a good practice to use the material heaters on the proportioner to warm the material slightly above desired application temperature and have the hose heat set to the desired temperature. Doing this will reduce the hose heat usage and energy consumption which will extend the service life of the hose. Always set the preheaters approximately 3-5 degrees more than the hose heat. NEVER set your hose heat higher than preheaters.

Leaving a hot hose on the rack will result in excess heat building up that will damage your hose. The Hose Heat Controller compares the set temperature to the temperature reported by the TSE and if the set temperature is lower, a green indicator light will flash in the upper left corner of the controller indicating that it is calling for hose heat. The relay is in the base of the unit on the left side. When prompted by the Hose Heat Controller the Hose Heat Relay will complete the circuit supplying full voltage from the Transformer to the red wires that heat the hose. The transformer has a “pigtail” of wires each labeled with a different voltage. The chart below shows how to select the appropriate voltage wire for the unit. The lead typically used for a 200-foot hose system is the 64-volt lead wire. In addition, a Zero-volt wire from the Transformer pigtail must also be connected to the Hose Heat Relay as shown below. When this happens, the relay will complete the circuit allowing power to flow down the hose. It may simplify the process to view the Hose Heat Relay as a switch. When the Temperature Controller is calling for hose heat, the relay switch is flipped, which completes the electrical circuit enabling power (and heat) to go to the hose. When the controller is not calling for heat, the relay switch is shut off, which interrupts the circuit and prevents power from going to the hose. Failure to perform this maintenance may void any manufacturer warranty. Before correcting any kind of defect, make sure the Main Power Switch is OFF. NEVER access the inside of the Control Panel with the Proportioner power supply ON. The Pneumatic Unit is a component that works under pressure. Do not open any connection or carry out maintenance on components subject to pressure until all pressure has been bled to zero. The information provided in this chapter will serve as a guideline to detect and resolve problems, should they arise.

Check electrical circuit breakers, compressor, etc.Drums should be off the concrete floor to prevent cold transfer. For coatings, the B-side should be pre-mixed. Mixer should be lubed regularly and working properly. This is normal. Make sure gauges read at least 50 psi at the low end of the cycle; if it is bouncing off zero, the machine is being starved for material. How they are taken care of will determine the service life. Do not use a coiled hose and do not leave the hose on the hose rack. It will create hot spots and excess heat which will damage the hose. If machine is losing pressure on the “down” stroke, the problem is either debris lodged in lower check ball of pump causing the check ball not to seat. Either the piston seal has excessive wear or the piston check ball located in the end of the shaft is clogged with debris. Inspect hose for leaks or damage. If clogged, clean or replace screen. If not, proceed to Step 2. If fluid pressure is still off-ratio, proceed to Step 3. If these steps don’t resolve the problem, there could be an air pocket in the A-Side pump usually caused by the barrel pump sucking air. Proceed to step 4. This will move the air pocket out of the pump. This may require a screwdriver to pry the solvent cup loose from the pump head. When replacing the chevron packing, the packing nut should be snug but not too tight, as it is possible to tighten the nut to the point of locking the pump up.Tighten the packing nut in very small increments as needed to help stop any excess material that is coming past the top seal. Once this is done, check to see if the green light in the upper left corner of the Hose Heat Controller is blinking (see image below-red circle). Proceed to Step 2. If the light is not blinking, there is likely a problem with the controller. Check all inputs into the back of the Hose Heat Controller to make sure everything is secure. If the problem persists, the Hose Heat Controller may be damaged and require replacement.

This can be validated by swapping one of the other controllers (either of the material heat controllers) with the Hose Heat Controller. If the green light begins to flash, check to see if the hose is heating. If you have hose heat, simply replace the defective controller with a new, programmed temperature controller. If there is still no hose heat, proceed to Step 2. With the system running and calling for hose heat, check the hose electrical system. Using the voltage meter, pierce the insulation with the black probe on one of the two red hose heat wires that extends out from the front of the proportioner. Next, place the red probe in the other red hose heater wire. With both probes in place, read the volts displayed on the meter.The most common reason is that the wire became disconnected at a wire coupler as shown in the pic below. The most common area of disconnections are: These are the two most common places issues are found: This connection and fuse can be checked without rig power by performing a simple continuity test using your electrical meter. Set the meter to the continuity setting and place a probe against the wire on each side of the fuse (black wire and red wire.) If there is continuity, the meter will beep. This indicated power can flow through this area. The fuse is blown and needs to be replaced. The next step is to validate the relay is doing its job. There are two smaller input wires and two larger output (load) wires that come from the Hose Heat Controller. One of these wires is a black “0 Volt” wire from the Transformer and the other is Red wire that extends out of the front of the proportioner. This test MUST be performed when the system is on and the Hose Heat Controller is calling for heat (flashing green light). To do this, set the electrical meter to the continuity setting and carefully place one probe on each output or load post. If no continuity exists, the controller needs to be replaced.

Record the amp reading and then follow the same procedure for the other red hose heat wire. Both readings should be very close to each other and between 35 and 45 amps. If the readings are lower than that but greater than zero:If it is between 35 and 45 amps, see if your hose heat issues have been resolved. If not, continue to the next step. If the displayed temperature does not increase as heat is applied, your hose heat controller will probably need to be replaced with a new, programmed controller. If the displayed temperature increases as heat is applied to the twisted TSU wires, the issue resides with the TSU wire somewhere down the hose. The usual cause is the exposed sensor wires at the end of the TSU being pulled out and away from the heated hose. This prevents the TSU from reading the actual hose temperature which typically results in the ambient temperature being sent to the Hose Heat Controller which in turn causes the controller to continue to call for hose heat. NEVER access the inside of the Control Panel with the Proportioner power supply ON. The Heaters are components that reach high temperatures; you must wait until they cool before handling. If the surface temperature exceeds 180F (82C) the Limit Switch will shut off the Heater power. This will lube the o-rings inside the air directional valve. The older style tends to clog up after many years and slow down the performance of the machine. You can identify it by one red air hose coming into the bottom of it and two red air hoses coming out the top that lead to the lower and upper plates of the air motor plates.These coils can be identified by looking on each end of the air distribution valve. There is one coil on the left and one on the right. They each have a wire coming out of them that leads into the electric console. These magnets pull a pilot valve their direction which in turn determines the direction of the air flow going to the air motor.

If air pressure goes into the bottom of the air motor it will force the piston up and if air pressure goes into the top of the air motor it pushes the piston down. Usually only one of the coils will go out at a time which will result in the air motor stopping in either the up or down position, depending on which coil goes out.They are mounted on swing brackets that are attached to the round upright bars that separate the two mid-plates. Before testing the machine, make sure that air pressure, electricity feeding to the machine, and all breakers are turned on. Perform the tests in the following order: These should be in the 0 position. If one or both are in the 1 position, then turn it back to 0. These flat screws are located on the top of the air valve just inside of the coil, on the body of the air valve. Turn one at a time from the 0 position to the 1 position. This should make the proportioner cycle one time, either up or down depending on which screw is turned. Turn the screw back to the 0 position. If the air motor didn’t cycle, then the air directional valve is not functioning correctly. The air directional valve will need to be replaced. If it is functioning correctly, turn the other flat screw to the 1 position. The air motor will cycle in the opposite direction. If it does not, the air directional valve is not functioning correctly and needs to be replaced. If the air directional valve strokes in both directions with the turn of the flat switches, then your air directional valve is functioning correctly. Proceed to test 2.Remember to turn off all electricity feeding the electric console before opening the lid. Disconnect the end of the two wires from the termination block inside the machine and test them for continuity. To test, place a screwdriver in front of the reversing switch that needs to be tested. If the switch is working properly, then it will test for continuity when there is metal in front of the switch.

If there’s no continuity when the screwdriver is directly in front of the blue reversing switch then the switch is not functioning correctly and needs to be replaced. Perform this same test on each switch to see if they are functioning correctly. If switches are functioning correctly, proceed to test 3.Knowing that both coils don’t usually go bad at the same time, assume that one of them is still working. Take both coils off and replace the left side coil with the right coil. It will make the air motor cycle one time. If not, then the coil is bad. Now repeat with the right side coil and put it on the left side. It will make the machine cycle one time. If not, then that coil is not functioning correctly, it will need to be replaced.
