WARNING: When the test feature is activated, outputs may be turned
on that may cause the car to move, the doors to operate and other
signals to come on. It is the operator’s responsibility to make sure an
unsafe condition does not exist. Take any and all the necessary
precautions to prevent a dangerous situation.
This could include
• unplugging the terminal blocks on the output boards (this is strongly recommended),
• removing the fuses in the output circuits,
• opening the appropriate safety devices.
While the test feature is activated, each input that is on will turn on the corresponding
output on the same board (Input Point 1 will turn on Output Point 1; Input Point 2 will turn
on Output Point 2 etc.). This allows the inputs and outputs to be tested by jumping the
desired input on, and verifying that the proper output comes on. Note: The outputs are
updated once every tenth of a second, so there may be a slight delay in turning on the
output after the input has been energized.
WARNING: Be very careful when jumping the inputs on. Make sure
you do not jump to the common on the input terminal strips. This will
blow a fuse, and could damage the input board components. The
input commons are the first and sixth terminals from the left on the
input terminal strip (see the schematic).
While the outputs are being tested, a meter can be used to verify that each output is
actually coming on.
The test will be stopped, and the outputs turned off, when any key is pressed.
