USLx and DSLx are Low (8) Named Up and Down Slow Limit switches low. Car performs emergency
stop and is not allowed to move. All calls canceled. If in a door zone
doors will cycle to allow passenger exit. Fault-bypassed in Construction.
System Verifies:
- Limit inputs USL and DSL low.
- 2 bus has power.
Correction:
1. Verify switches mechanically and electrically.
2. Verify input connections.
3. View System IO > System Inputs, USL and DSL for correct status.
4. Repeat learn operation (Utils > Landing System Utilities > Terminal
Switch Learn).
UTL and DSLx are Low (313) Up Terminal Limit switch and named Down Slow Limit both low (open). If
moving up, car will perform emergency stop. If moving down, car will
drop high speed, locate a floor, and cycle doors to allow passengers to
exit. Fault-bypassed in Construction.
System Verifies:
- Limit inputs UTL and DSL low.
- 2 bus has power.
Correction:
1. Verify switches mechanically and electrically.
2. Verify input connections.
3. View System IO > System Inputs, UTL and DSL for correct status.
4. Repeat learn operation (Utils > Landing System Utilities > Terminal
Switch Learn).
UTL and DTL are Low (11) Up and Down Terminal Limit switches are both low (open). Car will per-
form emergency stop and will not be allowed to move. All calls will be
canceled. If in a door zone, doors will be cycled to allow passengers to
exit. Cannot be bypassed.
System Verifies:
- Limit inputs UTL and DTL low.
- 2 bus has power.
Correction:
1. Verify switches mechanically and electrically.
2. Verify input connections.
3. View System IO > System Inputs, UTL and DTL for correct status.
4. Repeat learn operation (Utils > Landing System Utilities > Terminal
Switch Learn).
UTL is Low (154) Up Terminal Limit switch has opened. If moving up, the car will perform
an emergency stop. This switch should not open unless the car over-
shoots the terminal and opens the switch. The open switch prevents fur-
ther movement towards the terminal. Cannot be bypassed.
System Verifies:
- 2 bus has power.
- UTL input is low.
- USL (Up Slow Limit) input is low.
Correction:
1. If in error, verify switches and connections mechanically and electri-
cally.
2. Check the state of the System IO > System Inputs > UTL, against the
state of the switch (touchscreen landing system flags).
3. Repeat learn operation (Utils > Landing System Utilities > Terminal
Switch Learn).
