Product Overview

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.

Installation and Operation

1.  Receiver Installation
The receiver enclosure can be mounted to the exterior of an operator using four (4) #8 Machin screws, washers, lock washers, and nuts. Ideally, it should be placed in direct line-of-sight with 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 other 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.
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.

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 complete 1
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.
| 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:

Channel LED Diagnostics

LED is on, 41 regardless of edge
state 411| Edge resistance is below normal, edge wires are shorted| Make sure the edge is terminated with the proper
termination resistance (3k to 12k), check wires for damage| Relay NO/COM connected; pulse
output: 0 Hz
LED flashes 2x per cycle (0.25  seconds0 on, 0.25 seconds off)| Edge resistance above normal, improper
connection, damaged wires| Make sure the edge is terminated with the proper
termination resistance (3k to 12k)| Relay NO/COM connected; pulse
output: 0 Hz
LED flashes 3x per cycle| Transmitter batteries low| Replace batteries with type listed in specifications| Normal operation
LED flashes 2x( 0.5 seconds on, 0.5
seconds off)|  Transmitter batteries are discharged;
transmitter is damaged/inoperable| Replace batteries with type listed in specifications;  replace transmitter| Relay NO/COM connected; pulse
output: 0 Hz*

The system status LED (next to the power LED) can be used to compare the flashes. The LED for an unassigned channel will flash at the same rate as the status LED. 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.
