to make leveling switch motion effectively and correctly when the leveling spile of each
floor inserts;
（5）The set norm. Open / norm. closed input of leveling switch is inconsistent with the
actual one;
（6）Wrong motion or wrong installation position of slow down switch (when the lift car is
at the ground floor leveling position, the slow down switch on the lower single level
must motion, before the lift car goes upward to the leveling position of the second
bottom floor, the slow down switch on the lower single level must have been reset; when
the lift car is at the top floor leveling position, the slow down switch on the upper single
level must motion, before the lift car goes downward to the leveling position of the
second top floor, the slow down switch on the upper single level must have been reset).
（7）The set norm. open / norm. closed input of slow down switch is inconsistent with the
actual one;
（8）Encoder signal is interfered or Encoder has wiring error;
（9）Leveling switch signal interfered;
（10）Leveling switch failure or Encoder failure.
Note: in 2 levels / 2 stops self study, run the elevator to the lower limit after it enters
Inspection state. Proceed with normal self study after the upper leveling switch pulls away.
Note: Express car operation is only possible after well self study.
8.7 Express Car Operation
1．Test Run of Express Car
After slow car runs correctly, first make sure the elevator complies with safe operating
conditions. After well self study, proceed with express car test run. Specific steps are as follows:
1) Set the elevator in normal state.
2) Monitor the selected floor by hand-held programmer to select the floor where the elevator runs.
Test run is possible for single floor, double floor, multi floors and full trip.
3) Check whether the elevator can correctly close the door, start, accelerate, run, cut, decelerate,
stop, cancel and open.
4) In case of abnormal operation, follow the fault code (see Chapter IX) and operate accordingly.
2．Safety Test
1) Safety loop
Testing requirements: When the elevator stops, any of the safety switches motions. After safety
loop is disconnected, the elevator can not start; when the elevator is under inspection operation,
any of the safety switches motions. After safety loop is disconnected, the elevator takes an
emergency stop.
2) Door lock loop
Testing requirements: When the elevator stops, after any of the hall door locks is disconnected,
the elevator can not start; when the elevator is under Inspection operation, after any of the hall
door locks is disconnected, the elevator takes an emergency stop.
3) Safety loop relay adhesion protection (This function may not be tested if no safety loop relay)
Testing requirements: Press the emergency stop of control cabinet to disconnect the safety loop,
