DCLCR INPUT FAILURE
Description: The Rear Door Close Limit Contact (DCLCR) input monitors the rear door closed contacts.
5
DCLCR should be 120VAC during bottom rear access operation when the Bottom Access switch is toggled
to the up or down position. If your door operator connects to a UIO board on the car top (rather than up
the traveler to the controller), check that the "spare" inputs used for door operation are correctly pro-
grammed and that Serial Cartop Door Control (4-16) is set properly. Also verify communication to UIO (if
you have serial cartop door control) by placing F1 and F8 switches UP to view communication with boards.
Troubleshooting:
1. Verify 120VAC on the 2S bus.
2. Check that all hoistway doors are closed except for the bottom rear access hoistway door.
3. Check for 120VAC on the DCLCR terminal.
DL INPUT FAILURE
Description: The Door Lock (DL) input has detected a failure of the Hoistway Door Bypass (HDBA) or Bot-
tom Access Bypass (BABA) outputs, Gate Switch (GS), Door Position Monitor (DPM), or Door Lock Access.
Troubleshooting:
1. Check voltage on HC-CTL board terminal DLAB. DPM should activate two inches before DLAB.
2. If DL is active, GS must also be active.
DLR INPUT FAILURE
Description: The Rear Door Lock (DLR) input has detected a failure of the Rear Hoistway Door Bypass
(HDBBR) or Rear Bottom Access Bypass (BABBR) outputs, Rear Gate Switch (GSR), Rear Door Position
Monitor (DPMR), or Rear Door Lock Access Bypass (DLABR) inputs.
Troubleshooting:
1. Check voltage on HC-RDR board terminal DLABR. DPMR should activate two inches before DLABR.
2. If DLR is active, GSR must also be active.
DOL INPUT FAILURE
Description: The Door Open Limit (DOL) input is not in the correct state for the position of the door as
indicated by the Door Position Monitor (DPM) and Gate Switch (GS) inputs. If your door operator connects
to a UIO board on the car top (rather than up the traveler to the controller), check that the "spare" inputs
used for door operation are correctly programmed and that Serial Cartop Door Control (4-16) is set prop-
erly. Also verify communication to UIO (if you have serial cartop door control) by placing F1 and F8
switches UP to view communication with boards.
Troubleshooting:
1. If DPM is high, DOL must also be high. Check wiring to HC-CTL board terminal DOL.
2. If the GS input is high, DOL must also be high. Check wiring to terminal DOL.
DOLR INPUT FAILURE
Description: The Rear Door Open Limit (DOLR) input is not in the correct state for the position of the door
as indicated by the Rear Door Position Monitor (DPMR) and Rear Gate Switch (GSR) inputs. If your door
operator connects to a UIO board on the car top (rather than up the traveler to the controller), check that
the "spare" inputs used for door operation are correctly programmed and that Serial Cartop Door Control
(4-16) is set properly. Also verify communication to UIO (if you have serial cartop door control) by placing
F1 and F8 switches UP to view communication with boards.
Troubleshooting:
1. If DPMR is high, DOLR must also be high. Check wiring to terminal DOLR on the HC-RDR board.
2. If the GSR input is high, DOLR must also be high. Check wiring to terminal DOLR.
