An overspeed test can be initiated by:

an external logic input

the serial channel

directly from the digital operator
Overspeed Test via Logic Input
The external logic input can be used by:

setting the Overspeed Test Source
parameter to external tb1.

defining a logic input terminal to ospd test src
NOTE: This logic input requires a transition
from false to true to be recognized - this
prevents the overspeed function from being
permanently enabled if left in the true state.
Overspeed Test via Serial Channel
The serial channel can be used by setting
Overspeed Test Source (C1) parameter to
serial.
Overspeed Test via Operator


Press the ENTER key to begin the

The value in the Overspeed Mult (A1)
parameter is applied to the speed reference
and the overspeed level, so that the elevator
can be operated at greater than contract speed
and not trip on an Overspeed Fault.
When the Run command is remove after the
overspeed test, overspeed test reverts back to
its default of NO. In order to run another
overspeed test via the Digital Operator, the
above steps must be repeated again.
