4. TROUBLESHOOTING

SENSING EDGE SHIFTING

REQUIRED

•  (2) #6 x 1/2” self-drilling hex head screws

•  1/4” standard socket

INSTALLATION

To prevent the Sensing Edge from shifting within 

the mounting channel:
1.  Mount the Miller Edge mounting channel and 

Sensing Edge in accordance with 

Step 3: 

Sensing Edge Installation

.  

2. Insert 

self-drilling screws

 horizontally 

into the face of the mounting channel 

T-Slot 

2”-6” from the end of the interior side of the 

door. 

3.  Repeat step 2 on the opposite end of the 

inside of the door. 
Caution: Keep all tools away from the body of 

the Sensing Edge.

SENSING EDGE CHECK

SUGGESTED

•  Edge Tester (MET-101) 

•  Ohm meter (capable of measuring 10K)

TEST

Test the sensing edge for function:
1.  To verify the termination of a 10K ohm (T2) sensing edge, use a 

Edge Tester (MET-101)

 or an 

ohm meter

; the edge resistance should 

be ~10K ohms (9.5-10.5K).

2.  To verify the termination of a diode capacitor (T3) sensing edge, use a 

Edge Tester (MET-101)

; this is the only method to test a T3 

sensing edge.

3.  Press the Sensing Edge to confirm the resistance is less than 5 ohms.
