•  Press the ENTER key again.  The sub 

menu LED will go out and data ent LED 
will turn on. 

 

Three different functions are included in this 
sub-menu. 

 

 

 

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. 

The serial channel can be used by setting 
Overspeed Test Source (C1) parameter to 
serial. 
Overspeed Test via Operator 
The Digital Operator can also initiate the 
overspeed test by performing the following: 
•  While the Digital Operator display shows

the display will change to: 

 
 
 
 
 
 

 

•  Press the ENTER key to begin the 

overspeed test. 

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.
