Up Emergency Terminal Switch Position Fault, UP ETS POSITION FAULT
Description: Reported position upon encountering Terminal Switch differed from learned position by more
than set margin. Fault may be bypassed on Diagnostics > Fault Bypass tab.
Car Reaction: Emergency Stop: Motor and brake contactors immediately dropped. Hall and car calls can-
celled. After car is stopped, it will run at Correction speed to next available floor and cycle doors. Door Open
button will remain operational. If generated when car moving, fault latched and Fault Reset button must be
pushed to clear it. If generated when car not moving, fault will self clear when condition no longer exists.
Troubleshooting:
1. Physically check integrity of switch and wiring.
2. Check iBox input for switch.
3. On Diagnostics > Terminal Switches Status tab, compare Last pass position to Learned position for
switch. Verify Position Margin is reasonable (Configuration > Terminal Switches tab). If appropriate,
move switch closer to terminal landing.
4. Relearn NTS and ETS switches. Please refer to “Learning Normal & Emergency Terminal Limit Switches”
on page 4-8.
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 it. If generated car stopped, fault will self clear
when condition no longer exists.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Troubleshooting:
1. Logged in conjunction with speed or position fault at UETS. Check Event Log. Follow troubleshooting for
Up Emergency Terminal Switch Position Fault or Safety A/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 fault detected at Up Normal Terminal switch 'n' (1 to 5). When switch
opened, car traveling faster than defined Level 1 overspeed settings (sum of learned speed plus Overspeed 1
Margin percentage setting on Configuration > Terminal Switches tab) but not fast enough to trigger Level 2
overspeed fault. This fault may be bypassed on the Diagnostics > Fault Bypass tab.
Car Reaction: Controlled stop using Emergency Slowdown pattern parameters.
Troubleshooting:
1. On Diagnostics > Terminal Switches Status tab, compare Last pass and Learned speeds for switch. If
appropriate, increase Overspeed 1 Margin on Configuration > Terminal Switches tab.
2. May be caused by a change in Pattern parameters. Always re-learn terminal switches after any change to
Pattern parameters.
3. One or two floor runs may come in “hotter” than multi-floor runs.(switches learned making full hatch
runs). If short runs cause problem, increase Overspeed 1 Margin (Configuration > Terminal Switches
tab) or lower Standard profile - High Roll Jerk parameter (Configuration > Pattern > Modes tab.
4. May be caused by car following pattern poorly due to heavy load or poor speed loop performance. In this
case, adjust speed loop to follow pattern as well as possible and/or alter pattern parameters to produce
gentler deceleration and approach (then re-learn switches).Please refer to “Terminal Switch Overspeed
and Position Faults” on page 4-54.
