Theta Controller
Version 8 Eddy Current Brake Installation Guide
1-25
To determine whether you have a 120 volt or 240 volt Theta Controller, look at
the serial number/fuse(s) on the Theta Controller. If the serial number begins
with an “E”, and the control box has dual fuses, then it is a 240 volt unit; if the
serial number does not begin with an “E” and the control box has a single fuse,
then it is a 120 volt unit.
Figure 1-33: Theta Controller—Determine the Type
Note: Changing the fuse rating to the higher or lower specification does not allow
you to use the Theta Controller with an eddy current brake that was wired for
120 volt or 240 volt originally. Refer to “Verifying the Eddy Current Brake Wiring
Configuration” on page 1-26.
Note: If the eddy current brake has been rewired to a different voltage, you will
need a different Theta Controller. The original Theta Controller will not work.
