Up Normal Terminal Switch 'n' Level 1 Speed Fault, UP NTS'n' L1 SPEED FLT (n = 1 to 5)
Description: A Level 1 Overspeed fault has been detected at Up Normal Terminal switch 'n' (1 to 5). When
the switch opened, the car was traveling faster than defined by 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 the 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 the Diagnostics > Terminal Switches Status tab, compare the Last pass and Learned speeds for this
switch. If appropriate, increase the Overspeed 1 Margin on the Configuration > Terminal Switches tab.
2. May be caused by a change in the Pattern parameters. Always re-learn the terminal switches after any
changes to Pattern parameters.
3. One or two floor runs can sometimes come in "hotter" than multi-floor runs.(the switches are learned
making full hatch runs). If short runs are causing the problem, increase the Overspeed 1 Margin (Config-
uration > Terminal Switches tab) or lower the Standard profile - High Roll Jerk parameter (Configuration
> Pattern > Modes tab.
4. Can also be caused by a car that is following the pattern poorly, possibly due to heavy load or poor speed
loop performance. In this case, adjust the speed loop to follow pattern as well as possible and/or alter
the pattern parameters to produce a gentler deceleration and approach to the floor (then re-learn the
switches).Please refer to "Terminal Switch Overspeed and Position Faults" on page
Up Normal Terminal Switch 'n' Level 2 Speed Fault, UP NTS'n' L2 SPEED FLT (n = 1 to 5)
Description: A Level 2 Overspeed fault has been detected at Up Normal Terminal switch 'n' (1 to 5). The car
was traveling faster than defined by Level 2 overspeed settings (105% of sum of learned speed plus Over-
speed 1 Margin percentage setting on Configuration > Terminal Switches tab). This fault may be bypassed
on the Diagnostics > Fault Bypass tab.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Troubleshooting:
1. Check the Diagnostics > Terminal Switches Status tab to see how fast the car was traveling on the Last
pass by this switch. Check this value against the Learned speed for the switch. If appropriate, increase
the Overspeed 1 Margin on the Configuration > Terminal Switches tab.
2. May be caused by a change in the Pattern parameters. Always re-learn the terminal switches after any
changes to Pattern parameters.
3. One or two floor runs can sometimes come in "hotter" than multi-floor runs. (Remember that the
switches are learned making full hatch runs.) If short runs are causing this, you may have to increase
the Overspeed 1 Margin or lower the Standard profile - High Roll Jerk parameter.
4. Can also be caused by a car that is following the pattern poorly, possibly due to heavy load or poor speed
loop performance. In this case, you need to get the speed loop adjusted to follow pattern as well as pos-
sible and/or alter the pattern parameters to produce a gentler deceleration and approach to the floor
(then re-learn the switches).
