3.0 Mounting Instructions

3.1 Wall Mounting

4.0 Connections

4.1 PXL-500P Reader Wiring

5.0 Installation Verification

Note: Due to the physical size difference between cards and tags, tags provide approximately 50% less read range than cards. Refer to the Troubleshooting the Reader Installation section if the reader is not functioning properly.

6.0 MS Reader Troubleshooting

The reader does not recognize a card/fob

1. The reader wiring may be incorrect - Refer to section 4 to ensure the reader wiring to the controller is correct.
   
2. The reader may not receiving proper power from the controller - Verify the voltage being supplied to the reader is between 5 and 12v.
3. The reader may be mounted too close to a source of electromagnetic interference (EMI) - Devices such as computer monitors radiate electromagnetic interference that affects read range. When possible, relocate either the reader or the device to provide a greater distance between the two.
   
4. The wrong credential type may be being presented - The MS series readers are only compatible with Keri K-series credentials. The K-series credentials will have the letter K printed in the top-right corner preceding the imprint number.
   K-series credentials are: PKT-10x fobs, KC-10X credentials, MT10XM credentials and MT10XP credentials.
5. The reader shield may not be grounded correctly - The shield/drain wire of any reader/peripheral cables MUST be terminated to one of the following points-any corner screw attaching the controller to the enclosure, Pin 3 of TB10, the green ground lug (J6) on the controller applies to NXT controllers only), or the ground lug of the enclosure.  Failure to properly earth ground the reader/peripheral drain wire may result in unreliable communication or operation of the attached peripheral.
   
6. The lock may be powered from the same power-supply as the controller - It is advisable for the locks to be powered from its own power-supply because the noise generated by locks can be transmitted from the powered line and can interfere with the controller or potentially damage it.
   
7. Transorbs may not be installed at the locks - Transorbs are provided with the controller ship kit. They are used to protect the controller from voltage spikes induced on the port wiring by absorbing the excess voltage and slowly releasing it back into the circuit. Keri strongly recommends wiring in the transorbs provided with the controller ship kit.

The Reader Has a Short Read-Range

1. The controller may not be grounded correctly - Refer to the controller grounding document and check that the controller has a quality earth ground connection. Visit help.kerisys.com and use the search terms 'Grounding' to locate the appropriate document.
   
2. The shield wire on the reader cabling may be opened - Verify the shield line from the controller to the reader is one continuous, connected line and properly connected to the controller.
   
3. The reader may be mounted too close to a source of electromagnetic interference - Devices such as computer monitors radiate electromagnetic interference that affects read range. When possible, relocate either the reader or the device to provide a greater distance between the two.
   
4. The reader may be mounted too close to a source of electromagnetic interference (EMI) - Devices such as computer monitors radiate electromagnetic interference that affects read range. When possible, relocate either the reader or the device to provide a greater distance between the two.
5. The reader may be powered by a switching power-supply - Switching power supplies are known EMI sources. Change to a linear, regulated power supply or position the reader far away from the power-supply.
   
6. The lock may be powered from the same power-supply as the controller - It is advisable for the locks to be powered from its own power-supply because the noise generated by locks can be transmitted from the powered line and can interfere with the controller or potentially damage it.
