Problem Solution
Amplifiers on the second
(cascaded) module operate
independent of the priority control
scheme described on page 8. In a cascade arrangement, switch S1 must be set to the 1ST
position at the first module, and the 2ND+ position at the second
module, and all subsequent modules, as described on page 9.
Also, be sure wiring at the IN/OUT CNTL terminals at TB26
conforms to Figure 5 or Figure 6 on pages 4 or 5, respectively.
After performing all wiring checks,
trouble-shooting, etc. as described
in this section, the module still does
not function properly. Contact GAI-Tronics service for repair or replacement of the
module in accordance with the information provided on page 10.
