22 March Controller Diagnostics
22 March Topics Covered: Diagnostics that allows you to check basic controller and reader functionality through the address display on the controller and the optional LCD-1 display Controller status LEDs (on-board indicators)
22 March Controller Diagnostics All diagnostic routines are built into the controller’s firmware and hardware Detailed information on using the diagnostic routines can be found in the Troubleshooting and Diagnostics Reference Document –This document can be found on the Keri CD or on the Keri Systems web site (
22 March LCD-1 Firmware diagnostic routines require a Liquid Crystal Display module (LCD-1) Diagnostic tests are accessed and results displayed through the LCD-1
22 March Sharing the LCD-1 One LCD-1 can be shared by multiple controllers LCD-1s are “hot pluggable” –After inserting an LCD-1 on a “hot” controller, double-click S1 to reset the display
22 March Available Diagnostic Tests A/B Receiver Signal Quality (only for Keri PXL-500P/510P proximity controllers) PXL-500/510 Controller Inputs The SB-593 Satellite Board Inputs test is not yet implemented
22 March Accessing Diagnostics Click S1 on the controller until the “TEST” label appears Double-click S1 to enter the diagnostics section
22 March Accessing a Specific Test Click S1 to step through the individual diagnostic tests When the desired test is displayed, double- click S1 to enter that test
22 March Receiver Signal Quality Test This test measures the strength and the amount of interference in the reader signal received by the controller NOTE: This diagnostic routine puts the reader into a test mode that disables it for access use until the test is exited – presented cards affect the quality of this test
22 March Performing the Test As the routine runs, the LCD-1 displays a milli-volt (mv) reading –This reading reflects the quality of the reader signal received by the controller –Monitor the value displayed over 10 seconds - the reading will fluctuate, but you can note an average value
22 March Analyzing the Results The average MV reading value should be less than 500 mV –A significantly higher reading indicates the reader is receiving electro-magnetic interference Affecting the reader’s read range and reliability –A significantly lower reading indicates the controller is receiving a weak signal from the reader The weaker the signal, the lower the reader’s read range will be
22 March PXL-500 Controller Inputs Test Verifies that the controller can sense the change-of-state (open – closed) for the three inputs AUX – Auxiliary RTE – Request to Exit DR1 – Door
22 March Performing the Test The inputs test shows on the LCD-1 an indicator for each input that is closed Indicators for inputs that are open are not displayed –In a typical application the Door input is normally-closed and the AUX and RTE inputs are normally-open
22 March Performing the Test Toggle the inputs to see the change-of-state –Open door –Closed AUX and RTE
22 March Analyzing the Results Usually, if an indicator for an input does not toggle on and off as that input is opened and closed: –The input switch is not working –The input wiring is misrouted
22 March Exiting Diagnostics Click S1 and step through the tests until “EXIT” appears Double-click S1 to exit diagnostics
22 March Controller LEDs Power Fuse Power Status –With Over/Under voltage display Communication –RS-485 controller network –RS-232 master controller to PC Relay Status –Door Lock and Alarm Wiegand Reader Voltage –PXL-500W/510W controllers ONLY
22 March Power Fuse LED When FUSE LED 1 is on, a problem exists with the physical power wiring connection to the controller –OFF = no problem –RED = power and ground lines are reversed –GREEN = an excessive current draw condition exists (i.e. a power line short)
22 March Power Status – Over/Under Voltage When POWER LED 8 is red, a power over/under voltage condition exists An approximate voltage reading is given on the address display When LED 8 is green, power is at an acceptable voltage level
22 March RS-232 Communication Status TXD/RXD LEDs 2 and 3 flicker red/green as data is transferred These LEDs are for the primary RS-232 serial communication line (on all PXL-5xx controllers) –Between the PC and the master controller
22 March RS-232 Communication Status TXD/RXD LEDs 4 and 5 flicker red/green as data is transferred These LEDs are for the optional RS-232 serial communication line (on PXL-510 controllers) –Between an alarm panel and the master controller
22 March RS-485 Communication Status COMM LED 9 flickers red/green as data is transferred This LED is for the RS- 485 controller network communication line –On the master controller, it flashes every time it polls a slave controller –On a slave controller, it flashes every time it is polled by the master
22 March Lock and Alarm Relay Status LOCK LED 6 is green when the lock relay is activated (unlocking the door) ALARM LED 7 is green when the alarm relay is activated (an alarm condition such as a door forced open) These LEDs are off when the relay is inactive
22 March RS-485 Wiring Test Uses JP9, LED11, and LED12 to determine RS-483 wiring integrity Wire up the network and power up all controllers
22 March RS-485 (-) Wiring Jumper pins 1-2 of JP9 –If LED11 is solid RED and LED12 is off or flashing, the wiring is OK –If LED12 is solid GREEN, then +/- lines are reversed somewhere –If LED11 is OFF, there is an open in the RS-485 line –If both LEDs are solid ON there is either a short in the RS-485 line or there is a PXL-250 controller in the network with R45 installed
22 March RS-485 (+) Wiring Jumper pins 2-3 of JP9 –If LED12 is solid GREEN and LED11 is off or flashing, the wiring is OK –If LED11 is solid RED, then +/- lines are reversed somewhere –If LED12 is OFF, there is an open in the RS-485 line –If both LEDs are solid ON there is either a short in the RS-485 line or there is a PXL-250 controller in the network with R45 installed
22 March Wiegand Reader Voltage LED 10 is red if JP5 is set to provide 12 VDC power to a Wiegand reader –JP5 set to the right, provides 5 VDC power (factory default setting) –JP5 set to the left, provides 12 VDC power which can damage 5 VDC readers
