T775U SERIES 2000 ELECTRONIC STAND-ALONE CONTROLLER
9 62-0255—07
WIRING APPLICATION
EXAMPLES
Fig. 12 – 18 illustrate typical controller wiring for various
applications.
NOTE: The electronic Series 90 output provided with
modulating T775 models can not drive electro-
mechanical slidewire devices like older Series 3
modulating meters (prior to Series 6), V9055s,
and S984s.
NOTE: For a wiring example of three Series 90 Modutrol
Motors, refer to the T775A/B/M Series 2000
Electronic Stand-alone Controllers Installation
Instructions (form 62-0254).
