Up Emergency Terminal Switch Shutdown, UP ETS SHUTDOWN
Description: Up Emergency Terminal Switch opened at speed or position exceeding specified threshold. Fault
stays latched and Fault Reset button must be pushed to clear. If generated when car stopped, fault will self
clear when condition ends.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Tro ubleshooting:
1. Fault logged in conjunction with a speed or position fault at UETS. Check Event Log and follow trouble-
shooting for Up Emergency Terminal Switch Position Fault or Safety A (or B) UETS Level 2 Speed Fault.
2. Press iBox Fault Reset to clear the fault.
Up Normal Terminal Switch ’n’ Level 1 Speed Fault, UP NTS’n’ L1 SPEED FLT (n = 1 to 5)
Description: Level 1 Overspeed detected at Up Normal Terminal switch 'n' (1 to 5). When switch opened, car
was traveling faster than Level 1 overspeed settings (sum of learned speed plus Overspeed 1 Margin per-
centage setting on Configuration > Terminal Switches tab) but not fast enough to trigger Level 2 overspeed.
May be bypassed on Diagnostics > Fault Bypass tab.
Car Reaction: Controlled stop using Emergency Slowdown pattern parameters.
Tro ubleshooting:
1. On Diagnostics > Terminal Switches Status tab, compare Last pass and Learned speeds for switch. If
appropriate, increase Overspeed 1 Margin on the Configuration > Terminal Switches tab.
2. May be caused by pattern parameter change. Re-learn terminal switches if Pattern parameters change.
3. One or two floor runs can come in “hotter” than multi-floor runs.(switches are learned making full hatch
runs). If short runs are the problem, increase Overspeed 1 Margin (Configuration > Terminal Switches
tab) or lower the Standard profile - High Roll Jerk parameter (Configuration > Pattern > Modes tab.
4. May be caused by car following pattern poorly (heavy load or poor speed loop performance). If so, adjust
speed loop to follow pattern; alter pattern parameters for gentler deceleration and approach to floor
(then re-learn switches). Please refer to “Terminal Switch Overspeed and Position Faults” on page 4-61.
Up Normal Terminal Switch ’n’ Level 2 Speed Fault, UP NTS’n’ L2 SPEED FLT (n = 1 to 5)
Description: Level 2 Overspeed detected at Up Normal Terminal switch 'n' (1 to 5). Car traveling faster than
Level 2 overspeed settings (105% of sum of learned speed plus Overspeed 1 Margin percentage setting on
Configuration > Terminal Switches tab). May be bypassed on the Diagnostics > Fault Bypass tab.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Tro ubleshooting:
1. Check Diagnostics > Terminal Switches Status. Compare last pass and learned speed. If appropriate,
increase Overspeed 1 Margin on Configuration > Terminal Switches tab.
2. May be caused by Pattern parameters changes. Always re-learn switches after changes to Pattern.
3. One or two floor runs may be “hotter” than multi-floor runs. (Switches learned making full hatch runs.) If
short runs are causing this, increase Overspeed 1 Margin or lower Standard profile - High Roll Jerk.
4. May be caused by car following pattern poorly (heavy load or poor speed loop performance). Adjust
speed loop to follow pattern; alter pattern parameters for gentler deceleration and approach to floor
(then re-learn switches). Please refer to “Terminal Switch Overspeed and Position Faults” on page 4-61.
