UNTS1 Speed, 79 Learned value (percentage of Contract Speed) at which the car
should be traveling when encountering this switch during a normal run to the terminal in order
for normal stopping means to properly slow and stop the car. Please refer to “Learning Floor
Levels & Counterweight Position” on page 3-2.
UNTS1 Distance, 80 This is the distance in inches from the associated terminal floor
level position at which this Normal Terminal Switch is placed. This value is learned: Please refer
to “Learning Floor Levels & Counterweight Position” on page 3-2. NTS1 switches also provide a
definitive position check for the PI system.
UNTS1 Delta Distance, 81 This is the distance in inches on either side of the Up Nor-
mal Terminal Switch 1 position inside which the car must detect the Up Normal Terminal
Switch. If the switch is not detected within this span, the car will drop high speed. Generally set
to 6.0 inches.
UNTS1 Delta Low Speed, 82 Nominal value is 3% of Learned Speed. Please refer to
“Normal Terminal Switch Parameter Explanations” on page 4-130.
UNTS1 Delta High Speed, 83 Nominal value is 10% of Contract Speed or 20 FPM,
whichever is higher. Please refer to “Normal Terminal Switch Parameter Explanations” on
page 4-130.
UNTS2, 3, 4, 5 Speed, Distance, and Delta just as with UNTS-1, page 4-131, but with dis-
tances and speeds per your Contract Speed. For any switch that has been set to “unused”,
parameters can all be set to 0.0.
• Below 400 FPM: NTS2/3/4/5 switches normally set to unused.
These are starting values and will need to be adjusted according to actual car performance.
Once you are able to run the car at contract speed, tune the settings to prevent unintentional
tripping. Please refer to “MPI-A Diagnostics” on page 4-67.
