Product Overview
Figure 1 - WEL-200T (transmitter)
Figure 2 - WEL-200R (receiver)
The EMX WEL-200 system provides a complete wireless solution for interfacing sensing
edges with gate and door operators, while ensuring compliance with 2018 UL325
monitoring standards. Each transmitter can run for up to two years on two AA lithium
batteries. The receiver connects with up to four transmitters, with separate relay and
pulse outputs for open and close edge functionality.
With enhanced diagnostic features, the WEL-200R will make installation and
maintenance easy and reliable. Feedback is provided for all fault modes, including
edge open and short conditions, low battery, and failed transmitters.

Document no. 10320104 Revision 2.0 3-1-19
Installation and Operation
1. Receiver Installation
The receiver enclosure can be mounted to the exterior of an operator using four (4) #8 machine
screws, washers, lock washers, and nuts. Ideally, it should be placed in direct line-of-sight with the
transmitters, with no obstructions between the WEL-200R and the WEL-200T.
1. Mount the receiver.
2. Determine the monitoring method required by the operator.
3. Remove the cover. If the monitoring method is using relay contacts, then set the internal DIP
switch settings for each channel to either OPEN or CLOSE direction relay function depending on
the location of each edge.
4. For 10K resistive monitoring, place the jumper in the 10K position for both OPEN and CLOSE
direction relays.
5. Pulse outputs are available for open collector pulse type monitoring.
6. Wire the appropriate output to the operator. Proper installation for cable grip, see below.
7. Connect the power to power terminals.
Mounting extended with antenna above edge of the operator
NOTE: It is recommended to place the RX in a location where there is clear, line of site, between the RX
and all of its TXs. This can be accomplished by extending the top of the RX approximately 1” above the
top edge of the operator, mounting on top of the operator, or on a side that is in line of site with both
edge transmitters.

Document no. 10320104 Revision 2.0 3-1-19
CABLE GRIP INSTALLATION for both transmitter and receiver
The cable grip provides a NEMA 4X rating. To maintain a watertight seal follow these instructions:
a. Cable must be 0.181 –0.312 (4.6 –7.9mm) diameter for proper seal using the cable grip
insert as supplied. A separate white insert is provided when using cables sizes 0.069 –
0.187 (1.8 -4.7mm). To maintain a watertight seal, use only round cables, do not use
individual wires or any cable that is not round.
1. Remove sealing nut.
2. Remove dark insert from body (compression fingers) and replace with white insert.
3. Hand-tighten the sealing nut to secure.
a. Hand-tighten the sealing nut as far as possible. Hold the body hex stationary with a
wrench. Using a second wrench, tighten the sealing nut to 40 in. lbs. until the cable is
securely held in place.
b. If the cable has different diameter point the cable ingress down to prevent water
penetration.

Document no. 10320104 Revision 2.0 3-1-19
2. Connecting
Connecting is a two step process. First, on the receiver, press and hold the channel assignment
switch until the green status LED begins rapidly flashing, then release; this will clear any existing
assignment for that particular channel. Hold down the connection switch on the transmitter. If it
is not currently connected to a receiver, it will begin flashing rapidly until successfully connecting.
Detailed instructions are given below.
2.1. Apply 12-24 VDC/VAC to the WEL-200R (receiver), wait for initialization to complete1
2.1.1. If there are no existing connections, the receiver’s status LED will blink rapidly
while it is finding a clean operating frequency (this can last a few seconds)
2.1.2. After initialization, the system status LED will flash on/off once every 2 seconds
2.2. Set channel to the desired OPEN/CLOSE direction function using the MODE dip switch
2.3. Install 2 AA Lithium batteries in the WEL-200T (transmitter)
2.3.1. The green LED on the transmitter will quickly flash 2x every two seconds
2.4. Install a properly terminated edge to the transmitter (8.2k or 10k termination)
2.5. On the receiver, hold down the desired channel assignment switch until all four channel
LED’s activate and the system status LED begins flashing rapidly, then release the
switch.2
2.6. On the transmitter, hold down the connection switch (next to the terminal block)3
2.6.1. The LED on the transmitter will begin flashing rapidly after ~4 seconds
2.6.2. Upon successful connection, the LED will flash once every two seconds
2.6.3. If the transmitter fails to connect, it will return to its initial state, with the LED
flashing twice every two seconds. If this occurs, repeat step 2.6. If the
transmitter will not connect, proceed to the troubleshooting section.

WEL-200™ Operating Instructions 11
Document no. 10320104 Revision 2.0 3-1-19
2.7. Testing
2.7.1. Without activating the edge, observe the channel status LED, it should be OFF.
2.7.2. When the edge is activated, the receiver channel status LED will turn on and
the corresponding OPEN/CLOSE direction output will activate. The transmitter
status LED will blink once every second when the edge is activated.
2.7.3. If the channel does not exhibit this behavior, double check the edge
wiring/termination and transmitter batteries.
Notes
1. If channel 1 and 4 switches are pressed simultaneously during power up, the receiver will
perform a factory reset and clear all programmed channels.
2. Channel assignment mode will exit under the following conditions:
a. Successful connection to a transmitter
b. 60 second timeout
c. User selected exit
i. Pressing channel 1 and 4 switches simultaneously for more than 2 seconds
3. To remove a connection from the transmitter, hold down the connection button. The
LED will turn on solid for several seconds, and then blink twice every 2 seconds when
disconnected.

Troubleshooting
Under normal operation, the WEL-200R STATUS indicator LED will flash once every two seconds.
This is referred to as a cycle (one second on/one second off). Any fault that occurs will cause the
associated open/close output to change state. Output state refers to the output assigned to the
channel via the OPEN/CLOSE switch on the receiver. The main faults indicated by each channel
LED are as follows:

When channel assignment mode is entered, the active channel’s LED will turn on for 0.25
seconds, once per cycle.
If the edge resistance is above normal, due to lack of/improper termination or cable
damage, the offending channel’s LED will turn on for 0.25 seconds, 2x per cycle.
If the transmitter batteries fall below their ideal operating voltage , the LED for its assigned
channel will turn on for 0.25 seconds, 3x per cycle.
