BUFFER TEST
1. The physical goal of the buffer test is to run the car at full speed into the
buffer under power without dropping the brake, thus breaking traction. This
is done in the down direction to test the car buffer and the up direction to
test the counterweight buffer.
2. Set the slowdowns to a value of 00001. This will be done for all the speeds
(S1, S2, and S3) in | MAIN MENU | SETUP | SPEEDS & SLOWDOWNS | S# |
S# SLOWDOWNS | S# ALL.
a. Record original value of S1 All:__________
b. Record original value of S2 All:__________
c. Record original value of S3 All:__________
3. Temporarily change all 3 to 00001 to perform test.
4. Jump out the UET and DET inputs to M24.
5. Jump out the finals by jumping terminal block SF1 to terminal block PIT on
the MR din rail.
6. Set the Brake Drop Delay – Fault to the maximum of 2.55 seconds do this by
going to | MAIN MENU | SETUP | TIMERS | BRAKE DROP FAULT.
7. Ensure the hoistway and car-top are clear of any mechanics.
8. Move the car to a door zone near the center of the hoistway to ensure the
car runs at full contract speed.
9. Enter Car call to the bottom landing.
10. When test is finished restore the S# All slowdowns changed in Step 3.
