To close the lift doors, DC relay shall pull up and stay up until the DFC input is switched and the locks are made.
If DFC input does NOT switch, "DCPfail" – "Door Close Protect." shall appear on the LCD after a period of 25
seconds and drop DC relay. After a further period of 15 seconds, the doors will re-open and display "DCP" on the
LCD. This process is repeated until the fault has been cleared and the DFC input switches.
While in DCPfail/DCP mode, the controller switches on the OS output. See Inputs - Outputs, OS
When DLM = 02, DCPfail does not apply
When on Fire Service, DCP does not apply
If DFC input is switched and the Car Gate /Locks do not make, CG-bad or LCK-bad shall appear on the LCD.
DC shall stay active for a period of 5 seconds to try to push the doors closed. If the door locks still fail to make
then the doors shall then re-open. This process will be repeated until the fault has been cleared and the locks make.
Nb: When DLM = 02, LCK-bad does not apply, due to locks not making until a call is registered and cam lifting.
DFC must be switched to move lift, even on inspection
Dual Doors:
DLM EEPROM setting must be set to 01 for dual doors when DFC input is switched via door close relays.
DLI EEPROM setting shall be ignored
See DLI in EEPROM settings.
.
DFC input is switched via the external front or rear door close relay n/o contacts
The door close relays drop out via the door fully closed limit switches
When the external front or rear door close relay is in DFC LED will be on
