The motor drive circuit contains two fuses.  They are located on the power distribution PWA.  If it becomes 
necessary to replace these fuses, follow the procedure in Table 36 and refer to Figure 36 for fuse location.   

 

 

Disconnect power before opening the actuator case to replace the fuse(s). A 
potentially lethal shock hazard exists inside the case if the unit is opened while 
powered. 

 

 

Remove AC power from actuator. 

Remove the 6 screws and the extended cover of the actuator case.  See Figure 35. 

Lay assembly down on a flat surface.   

Remove connectors from CPU and power distribution PWA. 

Remove power distribution PWA. 

Locate the two fuses on the power distribution PWA.  See Figure 36.  Carefully remove and 
replace fuse(s) with Wickmann  T1 type 6A 250V, or equivalent (not available from Honeywell). 

Reinstall power distribution PWA. 

Reconnect connectors to CPU and power distribution PWA. 

Install a new gasket and replace extended cover.  Secure to actuator with screws.
