xIn the single speed model, relay K1 is for PB1 and relay K2 is for PB2.
xRelay K3 is not used in the single speed model.
xIn the dual speed model, relay K1 is first speed for PB1, relay K2 is first speed for PB2, and relay K3 is shared
as a second speed for PB1 and PB2.

xMAIN Relays K27A(NC), K27A and K27B change state when the system is turned on and remain latched while
the system is turned on. When the system is turned off, these relays revert to their normal state.
xFUNC Relay K10 is an auxiliary relay that closes during the START / ON sequence and opens when PB1 and
PB2 are released.
xFor 9-36VDC power supply, wire #1 corresponds to the negative charge (-), wire #3 corresponds to the positive
charge (+), and wire #2 is for GROUND.
xThe circled numbers in the output diagrams above correspond to the wire numbers in the harness.
xSuppressors are recommended on contactors being driven by Flex relays due to the possibility of voltage
spikes.

Receiver Installation
The Flex Duo factory setting uses an internal antenna. If an external antenna kit is required, ensure
the MCX antenna cable located on the RF/decoder board inside the receiver is connected and the
jumper is moved from the INT to the EXT position.

For best reception, the receiver and/or external antenna should always be mounted in a location with a clear line
of sight to the transmitter. Ensure the mounting location of the receiver is not exposed to high levels of electric
noise. Mounting the receiver next to a variable frequency drive or an EMI / RFI generator may cause radio
interference.
Once the proper mounting location is identified, drill four holes (standard) or two holes (optional mounting bracket)
on the control panel, wall, or location where the receiver is to be installed.
If a mounting bracket is used, leave enough slack in the harness to accommodate sliding the receiver on and off
the bracket.

General Operating Procedures
The Flex Duo system consists of the transmitter(s) and receiver containing all of the required settings to work
upon quick installation.
The default operation of the Flex Duo system has the two pushbuttons configured as an interlocked pair to perform
as motion control with the corresponding output relays setup for momentary contact closure. Pressing both buttons
at the same time after start-up will result in no output because the buttons are configured as interlocked.
Turn System On
1. Install the provided batteries in the transmitter and power on the receiver.
2. Elevate the STOP button to power on the transmitter.
3. Perform the START command by pressing and holding both PB1 and PB2 at the same time for 1 second to
activate the receiver MAIN relays and to establish a communication link with the receiver.
When the receiver MAIN relays are activated, the Status LED will change from constant green to constant orange
(system on). Press any pushbutton on the transmitter to begin operation. Pressing any pushbutton prior to
executing the START command at startup will result in no signals transmitted (Status LED blinks orange).
Turn System Off
Press the STOP button down to power off the transmitter, disconnect the receiver MAIN relays, and to disconnect
the communication link with the receiver.
After 5 minutes of inactivity (pushbutton not pressed), the receiver MAIN relays are temporarily disconnected. The
Status LED blinks 3 reds and then shuts off. Press any pushbutton to resume operation.
