This top-quality made-in-USA RPL-6620 controller is a convenient replacement for the 3014199 and 3006620 controllers used on the Buyers SaltDogg SHPE poly v-box salt spreaders. It exactly matches the electrical performance parameters of the 3006620, while exceeding those of the 3014199 control box with a 20% performance increase.
The RPL controller is built with the toughness and reliability of time-tested low-loss analog PWM power-control electronics, and integrated with clever solid-state function management software. It therefore has none of the digital quirkiness and oddities often observed in digital controllers.
This 12-Volt DC variable-speed dual controller works with these SaltDogg poly-hopper v-box models: SHPE0750, SHPE1000, SHPE1500, and SHPE2000 (black, red, yellow). The power & harness connectors are identical for easy drop-in installation and replacement.
Since 2004, the SaltDogg 3006620 was configured so that every time the power was turned on, the spinner was given a hard-start pulse of 30-amps for 2 seconds. The idea was originally that this would free a jammed spinner. However, user feedback indicates that a jammed spinner is rare and this behavior is not helpful. It merely flings the salt–sand mixture out at maximum velocity and maximum areal coverage — wasting material.
Now, the RPL-6620 controller is the first to market (Nov 2017) with the steady-start spinner. This new feature means that when the power is turned on, the spinner spins at whatever rate the spinner dial is set to. So, if the dial is set to "0", for example, the spinner will not spin at all at start-up — because it does not receive a starting pulse as the previous version of the controller did.
Of course, this also means that you can perform a "do-it-yourself hard-start" by setting the spinner dial to "10" before you turn the power on. Now the spinner will be jolted with 30-amps at start-up for any duration you wish.
Every time the controller is turned on, it does a power-on self-test (post). If the test was successful, the red "Jam" led will blink. If the red jam light blinks 1 time, it shows that the controller has the older hard-start spinner feature. If the red jam light blinks 3 times, it indicates that the controller has the newer firmware with the steady-start spinner.
The ignition wire was specified by Buyers Products Company for the 3006620 controller as a safety feature — to prevent a dead battery in your vehicle.
The ignition wire must receive 12V positive current for the controller to function. The idea is to hook it to a 12V (+) source that has current only when the truck's ignition is turned on. That way, the controller can't accidentally be left on to drain the battery when the truck's engine is off.
This is just like your dashboard radio. If the radio is playing when the ignition is turned off, it will power down.
In fact, the 12V positive that powers the radio is an excellent source of 12V (+) for the controller. Simply tap into that wire and feed the current to the controller's red ignition wire. The ignition wire needs only a very small amount (about 120 mA) of constant 12V positive current for the controller to operate. So there is no chance of blowing the fuse to the radio.
However, sometimes there is no convenient source of 12V positive current that is controlled by the ignition switch.
To simplify installation, we can eliminate the ignition wire. We have been trained and are authorized by the manufacturer to remove the ignition wire from the RPL-6620 controller —— if desired by the purchaser.
The controller will be fully functional. But it will now power-on even if the truck's ignition is turned off. So please remember to turn the controller's power off when not in use.
Historical fact: The Karrier Omega 2070 controller never had an ignition wire, by design.
There is no cost for this service. The modification will not void your warranty. And the shipping of your order will not be delayed.
To request this option when purchasing, simply type a message into the comment box and ask for removal of the ignition wire.
