Should the controller show any of these faults
- When powered, the controller remains stuck on "FAS"
- When no bank is switched on, the controller displays a capacitive
cosϕ (negative cosϕ)
- The controller displays a cosϕ that does not correspond to the
system's.
- The controller alternately displays " C.O.S. " and "-.-.-.".
- The controller displays a cosϕ below the one set and fails to switch
on any banks.
- The controller switches on all the banks even in the absence of loads
and fails to switch them off.
We recommend performing the following checks:
- Check the positioning and connection of the C.T. (See chap. 6 - Page

- Check that a current greater than 200mA is circulating on the
secondary winding of the C.T. (the power factor correction function
requires a working load).
- Check that the setup parameters have been correctly configured (See
