the learn procedure, do the following. Place the magnet on the learn area and the LED will go to a
constant RED state. Leave\hold the magnet in place on the receiver learn area until the red LED light
goes out. (Approximately 12 seconds) This action completely clears the receiver’s memory. It’s akin to
reformatting, or freeing up all of the space on a computer hard drive. Once you have cleared the
memory, proceed with the standard learn procedure detailed above for each of the transmitters you
wish to use with the device. If, after all of the procedures detailed above are completed, the unit is still
not functioning, check the batteries in the transmitter once again. (Occasionally, even new batteries fail,
or are defective from the factory If you have a voltage meter, confirm that battery voltage, from both
AAA batteries combined, is at least 2.7 volts) If that still does not solve the problem, contact our
wireless control customer service at (515) 264-1808 for assistance.
During standard operation, to confirm the receiver is picking up a signal from the transmitter, the
RE3 receiver unit will respond to keypad inputs through illumination of the receiver LED (see diagram
for location below)
Power Management/Restrictions:
The RE3 and RE6 may be used to directly control/provide power to applications. The systems have
maximum current ratings which need to be observed. The total maximum allowable current handling
capability for each system, at any given instance, is as follwows: RE3 System- 5.5Amps / RE6 System
7.5Amps Exceeding these limits will result in damage to the unit. For applications needing higher
amperage, the RF systems can easily be used in conjunction with a relay/contactor that is suitably
rated to the higher amperage load. You simply drive the relay\contactor inputs, with the low amperage
outputs of the wireless receiver. In this type of configuration, the high amperage load flows through the
relay/solenoid, instead of flowing through the wireless unit, so it protects the RF unit against
overloading and potential damage. Should you have any questions regarding this type of application,
feel free to contact the Rowe Electronics customer service department at 515-264-1808. Additionally,
you should always be sure to keep the main battery on your implement fully charged and in good
operating condition. Operating the wireless control system with the main battery disconnected, or
severely discharged, can result in damage to the RF system. You should disconnect the RF unit when
charging your battery to avoid any potential over-current issues. Incorporated into the system is a
thermal fuse that will, in most cases, shut the unit down if it encounters overvoltage situations or
potentially harmful electrical conditions. It is a self protective feature of the RF system, but there are
some conditions that it cannot protect against. If the thermal fuse activates, once the unit cools down,
the RF system will reset itself, and continue to operate normally. Should this occur frequently, inspect
the electrical system that is powering the RF unit.
It is also imperative that no electrical “feedback” is allowed to enter the inactive outputs of the RF
unit. The use of protective diodes is recommended in such applications where voltage may be sent
through the same circuit that the RF unit outputs are connected to. This situation can occur when a
manual control switch is also connected to the circuit that contains the RF system. Do not allow back-
feed current to flow into any inactive output leads\circuits. Damage will result.
The RE3 wireless control system is crafted using high quality components, with long term service life
and superior performance being the ultimate goal. It is our commitment to provide products that not
merely meet your needs and expectations, but exceed them. Thank you for choosing our product.
