6-62 Manual # 42-02-7223 C1
Position Location Error Fault, POSTN LCTN ERROR FLT
Description: If the difference between the learned position of a floor (magnet) and the currently indicated
position of that floor (magnet) is greater than 2 feet, this fault is generated.
Car Reaction: Car will perform a terminal synchronization.
Tro ubleshooting:
1. Check that the iLand landing system is properly installed and adjusted. (Refer to Section 3 of this guide.)
Position Quadrature Fault, POSITION QUAD FAULT
Description: iLand quadrature signal not detected (one or both streams). At above 30 fpm, system expects
proper transitions on both quadrature signals.Fault may be bypassed on Diagnostics > Fault Bypass tab.
Car Reaction: Emergency stop.
Tro ubleshooting:
1. Verify that both quadrature channels are arriving at the iBox.
2. Hoistway screen: Verify absolute position increments when moving up and decrements when moving
down (on inspection). If absolute position does not change, there may be a problem with the iBox.
Position Quadrature Reversed Fault, POSITN QUAD RVRSD FLT
Description: Arrival sequence of quadrature streams indicates travel in opposite direction of commanded.
Car Reaction: None.
Tro ubleshooting:
1. Verify that the elevator moves in the requested direction.
2. On the Hoistway screen, verify that the cartop position increments when moving up and decrements
when moving down (on inspection).
3. On the Hoistway screen, verify that the absolute position increments when moving up and decrements
when moving down (on inspection).
4. Check JP1 jumper on iLAND-c. Position A is for normal mounting orientation; position b is for upside
down mounting position.
Position Speed Deviation Fault, POSITN SPEED DVTN FLT
Description: Safety processor compares distance travelled reported by position quadrature with distance
travelled according to motor rotation. If quadrature reports 48” travelled but motor reports less than 32”,
this fault is generated. This fault may be bypassed on the Diagnostics > Fault Bypass tab.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Tro ubleshooting:
1. Check velocity feedback from drive.
2. Check that Pattern Configuration/General tab Position Encoder Resolution is set to 256.
3. Check calibration of speed feedback signal.
