WEL-200 Wireless Edge Link Overview

The WEL-200 system provides a complete wireless solution for interfacing sensing edges with gate and door operators. This wireless edge link eliminates the wiring between the safety edge and operator control box while ensuring compliance with 2018 UL325 monitoring standards.

The WEL-200 operates up to 200 feet line of sight between transmitter and receiver. The receiver connects with up to four transmitters with separate relay and pulse outputs for open and close edge functionality. The transmitter for the WEL-200 is compatible with both 8.2K and 10K monitored safety edges.

 

Features of Our WEL-200 Wireless Edge Link

  • Long Range Operation: Operates up to 200 ft. (line of sight) between the transmitter and receiver.
  • Multiple Transmitter Support: Connects with up to four transmitters, providing separate relay and pulse outputs for open and close edge functionality.
  • Durable: Housed in rugged, watertight NEMA 4X enclosure.
  • Universal & Compliant: UL325 Compliant and Compatible with both 8.2K and 10K monitored safety edges.
  • Long Life: WEL transmitters will operate for two years on two AA lithium batteries.

 

NEW! Radio Signal Quality Display

The WEL-200 Receiver features a one-digit display that reports signal quality (0 to 9) for the selected transmitter, allowing for quick assessment of connection strength.

Why won’t my transmitter pair?

Pairing Error: The devices have likely paired but there is an error. Look at the channel light in use for an error blink code. If the blink code continues for 90 seconds or more then the device is paired.

PCB Compatibility: A green WEL-200 PCB only works with other green WEL-200 PCBs. Red and black on the other hand can work together.

Why do my batteries die so quickly?

Battery Type: Make sure you use lithium-ion batteries.

Connection Path: Make sure there is a clear path from the transmitter to the receiver, or else the device has to work harder to make a connection and that will use up more battery power. If the batteries are dying in 1 year instead of 2 years, this is probably due to bad connection.

Faulty Transmitter: If new Lithium batteries are dying within a month or two, the transmitter is faulty. Swap it.

How do I make sure that my devices are pairing and my edge works?

Step 1: Remove edge wires from transmitter.

Step 2: Attempt pairing at close range. Channel should change to two blinks and a pause.

Step 3: Connect edge wires to transmitter. Channel light should turn off when the device pairs.

Step 4: Once paired, test the edge. Channel light should turn on when you squeeze the edge.

Why does my channel blink faster than unused channels?

Line of Sight: Make sure there is good, uninterrupted line of sight from your receiver to your transmitter.

Radio Interference: To avoid radio interference, recalibrate your wireless channels. Hold down channel 2 and 3 until the power LED starts flashing and then release. Once the power LED stops flashing it is done recalibrating.

Why does my channel light blink twice and then pause?

Edge Issue: The edge is open, disconnected, or damaged.

Why does my channel light blink 3 times per second?

Low Battery: The transmitter has low battery. Replace batteries.

My pairing worked but my operator safety is triggered.

Dip Switch: Make sure dip switch is set to proper channel and relay.

Output Setting: Make sure the correct output is used for that gate operator.
