Installing the Rotating Switch Operator

If the 

Closed Torque

 setpoint is not modified, the torque after a normal 

Close

 opera-

tion equals the reference value. If a higher value is selected for the 

Closed Torque

 set-

point, the switch operator adjusts the final 

Closed

 position, based on the overall spring 

constant, to obtain the desired closed torque.

NOTICE

Adjusting the load resistor only affects low-speed jogging. The mechanical 

 

resistance is easily overcome during normal, high-speed operation.
Also, if additional torque on the control rod at the end of a normal, 

 

high-speed close operation is desired, select a new value for the 

Closed Torque 

setpoint on the 

Setup>General>Switch Operator

 screen rather than adjusting the 

load resistor.

Table 2 shows the possible resistor settings and the corresponding closed-reference 

torque values.
