Troubleshooting
Warning! Troubleshooting should be performed by qualified service personnel only. Before
calling the Technical support, verify the following:
Reader doesn’t read
1. Verify that no other proximity cards are in the reading field (up to 36 inches (91 cm) from the
reader).
2. Is a linear voltage regulated power supply being used with a backup battery? (12V@1.5A).
The use of switching power supplies is not recommended.
3. Is a DC common connected between the external power supply and the door controller?
4. Is the correct proximity card being used? (P10SHL, P20DMG, P30DMG, P40KEY).
5. Is the recommended cable being used? And is the maximum length respected?
6. Is the LED amber? If yes, there is not sufficient power for the reader. Verify the power supply
and wiring.
7. Verify the voltage at the terminals RED BLK. It should measure between 12.0-13.7VDC for a
12V supply and 24.0-27.6VDC for a 24V supply.
8. Verify that no other proximity cards are in the reading field (up to 36 inches (91 cm) from the
reader).
9. Is there ice buildup on the printed circuit or antenna posts? If yes, return the reader.
Reader has reduced read range
1. Is a linear voltage regulated power supply being used with a backup battery? (12V@1.5A)
The use of switching power supplies is not recommended.
2. Is the reader installed on a beam, pole, pedestal or other metallic material, which could cause
interference?
3. Is there a computer monitor (CRT) within 15 feet (5 m)? Note also that dye sub cards
(P20DMG, P30DMG) and keyfobs (P40KEY) will have less read range than their clamshell
counterpart (P10SHL) because of their smaller antenna.
4. Is the reader concealed in a box, cabinet, or behind a wall, which may interfere?
5. Verify the voltage at the terminals RED BLK. It should measure between 12.0-13.7VDC.
Though the reader works up to 27.6VDC, optimal performance is in the 12VDC range to
accommodate the antenna tuning.
6. Is there a DC common GND connected between the power supply and the door controller?
LED doesn’t flash or change color upon a card approach
1. Verify that no other proximity cards are in the reading field (up to 36” from the reader).
2. Verify that the “brown” wire or LED terminal is connected to the door controller's output.
3. Verify that the door controller's output programming is ok.
