1.6 Modes of Operation
1.6.1 Reset Mode
Reset mode is initiated when the elevator power is first turned on, or when the system is reset. When
the reset mode is initiated, the controller performs internal tests to ensure that both the car and
controller are electrically operational before putting the car into service. The car will not move until reset
mode is completed. Some of the internal tests that the controller performs are as follows: is the safety
string made up; is the elevator on inspection operation; is the door close limit open; are the interlocks
made up; is hoistway position correct. If all the safeties are made up, and the elevator is on automatic
operation, and it is at floor level, the elevator will go into automatic mode. If the elevator is not at floor
level, it will run slow speed down to the nearest floor, level into the floor, and reset the floor position
count.
