Fault
Description
Possible Cause/Suggested Fix
APS Com
Fault
NTS Processor has a
communications
fault with the APS
selector head.
• Faulty communications from the NTS CAN terminals on the 1121 MAIN
I/O board to the NTS CAN terminals on the 1134 COP board. Make sure
the CANH and CANL wires match.
• Termination resistors are usually place at the far end of each
BUS.
Verify the placement of the Termination resistors.
• Check the RJ
-45 connection from the 1134 COP board to the APS
selector camera.
• Try moving the termination resistors to other locations.
• Faulty device, try replacing each board individually, the
1121 Main I/O
board, the 1134
COP board and APS selector camera.
Comm
Fault
Device has a
communications
fault.
• Faulty communications wiring to the device.
• Termination resistors are usually place at the far end of each BUS.
Verify the placement of the Termination resistors.
• Try moving the termination resistors to other locations.
• Faulty device, replace board.
DZ Clip
Fault
The NTS processor
has a DZ clip fault.
The NTS processor
keep track of when
the door zone clip is
read at each floor. If
it enters a floor and
the clip is not read at
that floor three
times in a row, this
fault is logged.
• Check the placement of the clip when the car is dead level to the floor.
The clip should be in between the two channels of APS cameras.
Momentarily place your hand in front of the camera to cause the red LED
markers to turn on. The clip should be roughly in the middle of the red
LED markers.
• Verify that the clip is not broken or that the
correct clip is installed. Replace or install the correct clip.
HW Fl
Cnt Inv
Hoistway Floor
Count is Invalid on
the NTS processor.
One or more floor
count of an above
floor is less than the
floor below.
• The hoistway floor table is not setup properly. Check the valid floor
table of the NTS processor on the LCD Interface in the Hoistway Table
Valid Floor and Clips menu. Run car to the floor with the position of the
invalid floor or floors and learn the floor position.
• Complete the setup process.
• Faulty NTS processor. Replace the 1121 Ma
in I/O board. Contact Tech
Support.
