Emergency Terminal Switch Overspeed Tests

Per switch, this test verifies that an emergency stop will be initiated if an elevator that is moving
at a speed greater than 95% of the programmed contract speed encounters the ETS switch in
the cars direction of travel (DETS if the car is moving in the down direction, UETS if the car is
moving in the up direction). The empty car is set far enough away from the desired terminal
landing to achieve contract speed by the time it reaches the ETS switch in the selected direction.
The car is arranged to run toward the desired terminal landing without initiating any form of
slowdown. When the car activates the ETS switch, it will execute an emergency stop. The car
will then finish the run to a landing at leveling or correction speed.
1. Go to the Configuration > Drive > General tab and verify that Emergency rate limited
stop is set correctly. It is generally set to 7.0, and must be greater than the Emergency
slowdown profile - Deceleration parameter.
2. Position the empty car far enough away from the target ETS switch to allow a speed to
be reached that exceeds the learned overspeed value for that switch.
3. Go to the Diagnostics > Terminal Switches Status tab. Note the overspeed 2 value
learned for the emergency terminal switch to be tested.
4. Select Emergency Terminal Switch Overspeed Test on the Safety screen.
5. Set the test Speed to the overspeed speed for the switch/test, plus 10 fpm. Caution! If
the speed is set below the overspeed threshold, no slowdown will be initiated and the
elevator/counterweight will strike the buffer.
6. Follow on-screen instructions and perform the test. For additional information
minal Switch Overspeed and Position Faults" on page 4-55.
7. On the Operational Status tab, verify that the appropriate fault is shown in the Faults
window.
8. Continue testing the remaining emergency terminal switch by repeating steps 2 through
7.

Normal and Emergency Terminal Switch Position Tests

1. On the Configuration > Terminal Switches tab, for the switch you wish to test, set the
position margin to a negative value (place a minus sign in front of the value).
2. If you are testing an up terminal switch, run the car past the switch in the up direction at
contract speed (if possible). If you are testing a down terminal switch, run the car past
the switch in the down direction at contract speed (if possible). The car should stop
using the Emergency slowdown profile parameters.
3. On the Operational Status tab, verify that the appropriate fault is shown in the Faults
window.
4. On the Configuration > Terminal Switches tab, set the position margin for the tested
switch back to the original positive value
5. Continue testing the remaining switches using steps 1 through 4.
