3.2  Inside a Q actuator 

The PFU is fitted in the option board position in this actuator. Only one option board may be fitted at 
any one time. The necessary internal components must also be present; in this case a potentiometer 
and auxiliary limit switches at end of travel must be fitted to the actuator.  
 
The illustration below shows the Q version of the circuit board. The links for the bias resistors are 
shown in the ‘not terminated’ position. 

 
Digital Outputs from relay contacts are not supported from the Q actuator, nor is the ability to report 
the status of the remote control inputs as Digital Inputs. The following table shows the wiring 
harnesses that must be fitted and the function of each loom for the Q range actuator.

In a Q actuator there is a direct connection from PL2 on the Interface Card to SK5 of the actuator main 
board. 
 
To restore the interface card to its factory defaults and the associated default parameter settings, LK1 
on the Interface card should be fitted and the actuator power cycled (see Fig. 11).
