Procedure 6 - Adjusting the float / equalize ( continued )
Step | Action |
6The float voltage should be adjusted with the rectifier in service, as follows:
The rectifier is connected to the system and should carry some load. If the rectifier is connected in parallel with other rectifiers, verify that the total system load current is shared equally among the rectifiers. If the current reading is too low, or nil, slowly increase the FLT potentiometer, by turning it clockwise, until sharing is achieved. If the current reading is too high, or the unit is in the current limit mode, decrease the FLT potentiometer by turning it
counterclockwise.

High voltage shutdown (HVSD)
To verify or readjust the HVSD follow steps 5 to 8 of the “Rectifier Startup and Verification” section of this manual.
Cooling fan
Visually inspect the airflow intake for any obstruction by foreign objects, or excessive dust and dirt
CAUTION
Do not attempt to access the inside of the unit with a tool or a finger. Severe electrical shock could result.
Fan failure
If a fan alarm persists after the fan filter and assembly has been cleaned, replace the fan assembly as follows:
