DFO - Door Fully Open input

DFO input must change state when the doors reach the fully open limit/position
Single Doors:
Input state can be inverted with DLI setting. See DLI in EEPROM settings
To open the doors, DO relay shall pull up and stay up until the DFO input is switched. If DFO input does NOT
switch, "DOPfail" – "Door Open Protect." shall appear on the LCD after a period of 25 seconds and drop DO
relay. After 3-5 seconds (depending on the state of locks and DFC) DC will then pull in and display DOP (Door
Open Protection) on the LCD and close the doors. If a demand to open still exists, the doors will try to re-open.
While in DOP/DOPfail mode, the controller switches the OS output on. See Input - Output, OS
When on Fire Service, DOP does not apply
If DFO input is switched, indicating the doors are fully open, and the car gate/locks are still made the lift will
remain out of service with the doors open until the bridge has been removed from the locks, therefore ensuring the
lift cannot run with the doors open and the car gate/locks bridged.
One of the following faults will appear on the LCD;
"BCG" - "Bridged Car Gate", "BL1" - "Bridged door Lock1" or "BL2" - "Bridged door Lock2".
Dual Doors:
DLM EEPROM setting must be set to 01 for dual doors
DLI EEPROM setting shall be ignored. See DLI in EEPROM settings
DFO input is switched via the external front or rear door open relay n/o contacts
The door open relays drop out via the door fully open limit switches
When the external front or rear door open relay is in DFO LED will be on
See the following DO-DOPfail flow chart for more detail.
