Ascending Car Overspeed Test
The mechanic must determine appropriate weight, if any, to be placed in the car for this test.
1. Bring the empty car to the bottom floor with car and hoistway doors closed and locked.
2. Observe car speed at F3 POSTN SPEED and stand by to engage brake if governor over-
speed switch fails to open.
3. Use your preferred method to mechanically release the machine brake. The car will start
to move up the hoistway.
4. When the governor overspeed switch opens, the emergency brake will engage, stop, and
hold the car.
5. Reset the emergency brake: thereby releasing the emergency brake.
Safety Tests
This is a two part test. Car safety testing verifies proper operation of car safeties. The objective is
to set the safeties causing the machine to break traction. The overspeed must be sufficient to
cause the governor to trip mechanically and set the car safeties. The electrical governor switch
must not prevent the car from reaching the mechanical trip speed and the safety operated
switch (plank switch) must not open the safety string.
The counterweight safety test verifies the proper operation of the counterweight safeties. The
test is comparable to the car safety test, but performed in the opposite direction. If the counter-
weight has a governor, remember to jumper it out.
Car Safety Test
1. Run the car to the top landing.
2. Bypass the Electrical Governor Switch by placing a jumper from GOS1 to GOS2
3. Place a jumper between the CTL board terminals SAFC and SAFH.
4. Set F3 > Controller System Menu >
AUTOMATIC MODE FAULT BYPASS = BYPASS ON.
5. Set F7 Parameter 141 PROFILE SCALE to 115% (mechanical tripping speed is typically
about 115% of Contract Speed).
6. Control Techniques E300: Set parameter A28{E01} to the speed selected on the
controller for the test (1 FPM=5.08 mm/s).
7. Place a call to the bottom landing.
8. As the car over speeds:
• The governor will trip.
• Safeties will set.
• The machine will break traction.
• Car will stop.
9. Place the car on Inspection.
10. Reset the electrical governor.
11. Restore F7:141 controller parameter.
12. Restore drive operation.
13. Control Techniques E300: Restore parameter A28{E01} to its original value.
14. If unintended motion fault occurs, press and hold the EB RST button on the TC-MPI
board for 8 seconds.
