Troubleshooting the reader 39
None of the LEDs are on: Check that the beeper is enabled (See
Table 5 “Beeper sound level DIP switch settings,” on page 27),
then present a known good ProxLite test badge to the reader
while listening for the beeper.
If the beeper sounds, the reader is faulty and should be replaced.
If the beeper does not sound, check the power connections to the
reader and check the reader supply voltage at connector J1 pin 1.
The green LED is always on: The green LED indicates that the
door strike is open. It is controlled by the input on connector J1
pin 4.
1. Disconnect the wire on J1 pin 4. If the green LED stays
on, the reader is faulty and should be replaced. If the
green LED goes off then the problem is most likely not in
the reader.
2. Reconnect the wire on J1 pin 4 and measure the voltage
at J1 pin 4. Low voltage turns on the green LED. If the
voltage is low, check to see if the host system is turning
on the door strike.
The beeper doesn’t sound and the yellow LED doesn’t blink
when a badge is presented to the reader OR the badge read
range is very poor:
When the beeper sounds and the yellow LED
blinks off, it indicates that a badge has been read and its data sent
to the microcontroller.
Note: The beeper will not sound if it has been disabled. (See Table 5
“Beeper sound level DIP switch settings,” on page 27
.)
1. Models 941, 971 and 973: Check that the metal backplate
is installed correctly. See the appropriate installation
drawing in this manual for details.
All other models: Be sure they are not mounted on or
near a metal wall or large metal object.
