Section 6 – Trouble Shooting
Before beginning any trouble shooting, review Section 5 in this manual and check all wiring and look
for any loose connections. Double check your wiring! Be sure that you have a good VOM (Volt-Ohm-
Meter) to assist you when checking voltages and continuity. The following manuals may be helpful
when trouble shooting the access control system. These manuals are available (PDF format) on the
DKS Tech Support web site at www.dkaccess.com.

6.1 General Trouble Shooting
•
Be sure that the access control system (1833, 1835, 1837 or 1838) is operating properly
BEFORE making any connections to the 2348 elevator control board.
•
Check for communication between the access control system and the elevator control board
using the tests on the following pages.
•
If a card reader has been installed in the elevator car, be sure that this card reader is
communicating with the access control system.
•
Be sure that all necessary programming for elevator control has been set-up in the software
and has been down loaded to the access control system.
•
Be sure that the POWER LED on each 2348 elevator control board connected in the system
is ON when power is applied. If POWER LED is not ON, check for 16 VAC power at
terminals 35 and 36 on the MASTER board. The remaining three (3) boards controlling the
elevator car in the shaft are powered from the MASTER elevator control board.
•
Be sure that all ribbon cables connecting the boards together are plugged in properly.
•
Check the visitor control function by calling a resident from the 1833, 1835 or 1837. Have a
second person check the elevator control board to be sure that the proper relay activates
(relay LED turns ON) when the resident grants access.
•
Check the resident control function by activating the card reader in the elevator car with a
valid access card. Have a second person check the elevator control board to be sure that the
proper floor relay(s) activate (relay LED turns ON) when the system grants access.
•
Check the LED next to the wiegand input(s) at terminals 20-22 (wiegand 1 input) and
terminals 23-25 (wiegand 2 input). The LED will blink when the access control system(s)
(1833, 1835, 1837 or 1838) is sending wiegand data to the elevator control board. If the LED
is blinking, wiegand data is being received. If the LED is not blinking, check the wiring to be
sure that the Data1, Data 0, and common wires are on the correct terminals.
•
Check the DIP switches on the elevator control board. Be sure that the shaft and board
numbers are set correctly
•
Check SW-2 switch 8 to determine when the elevator control board will activate its
programmed floor button relay after a visitor is granted access. If SW-2 switch 8 is OFF, the
floor button relay will not activate until the elevator detect switch (a contact closure on
terminals 17 and 18) is activated.
•
Check that the relay shorting pins are set for proper operation - either normally open (N.O.) or
normally closed (N.C.).
•
The LOBBY HALL CALL relay shorting pin should be set for normally open (N.O.) operation.
