Verify Tach Error Does Not Trip on Emergency Stop
1. Set the iBox Fault/Function Bypass switch to the OFF position.
2. Make sure the Tach Error fault is no longer bypassed (Diagnostics > Fault Bypass tab).
3. With a full load in the car, run the car up and down the hoistway to verify that the Tach
Error fault is not generated.
4. Enter a car call several floors below the car (so it can reach contract speed).
5. While the car is running at contract speed (Operational Status / Speed - Actual), discon-
nect the GS terminal from the iBox.
6. The car should trip a Door Lock Fault and make an Emergency Stop.
7. Observe that a Tach Error fault is not generated.
