3. ON THE KEB DRIVE, SET THE TRIP SPEED FOR EACH SET OF NTS SWITCHES.
a. You can find your run speeds on the machine room SRU board under
MAIN MENU | DEBUG | SETUP | SPEEDS AND SLOWDOWNS
b. If job has one set of NTS switches:
i. Set drive parameter LX17 to 90% of contract speed (0.9 x
contract).
c. If job has two sets of NTS switches:
ii. Set drive parameter LX19 to 90% of contract speed (0.9 x
contract).
iii. Set drive parameter LX17 to 90% of second fastest run speed..
If S3 is your contract speed run then set LX17 to 90% of the
speed specified by S2.
GO TO “NTS SWITCH SETUP PROCEDURE”
NTS SWITCH POSITION SETUP
1. SET UT1
a. Do a normal, contract speed, run to the top terminal.
b. If car trips on the UT1 switch then:
i. Move UT1 switch toward terminal in 6” increments until a
contract speed run to the top does not trip on NTS.
ii. Now move the switch back away from terminal in 3” increments
until the car does trip.
iii. Finally, move the switch back 3” toward terminal.
c. If car did not trip in step 1.a then:
i. Move UT1 switch away from terminal in 6” increments until a
contract speed run to the top trips on NTS.
ii. Now move switch back toward terminal in 3” increments until
no trip.
2. SET DT1
a. Do a normal, contract speed, run to the bottom terminal.
b. If car trips on the DT1 switch then:
i. Move DT1 switch toward terminal in 6” increments until a
contract speed run to the bottom does not trip on NTS.
ii. Now move the switch back away from terminal in 3” increments
until the car does trip.
iii. Finally, move the switch back 3” toward terminal.
