WEL-200™ Operating Instructions 12
Document no. 10320104 Revision 2.0 3-1-19
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:
LED is on,
regardless of edge
state
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 seconds
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*
Transmitter batteries
low
Replace batteries with type
listed in specifications
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.
