ABSTRACT:
A testing system is removably connected to a control of an elevator system and selectively operated to perform a plurality of testing sequences. The testing system is removably connected with a closed loop elevator control and selectively and independently provides a number of artificial control signals characteristic of an operating condition for controlling the operation of the elevator system under test. The testing system may be used in a testing sequence with elevator systems employing gated rectifying circuits to accurately monitor gate pulses and other operating functions therein.
