WARNING: Disconnect primary power prior to servicing.
Maintenance and Alignment
•S1-9 OFF (ON = Microcontroller RESET)
•S1-10 ON (APC ON)
STEP 6 Turn on the Low Voltage breaker in the rear of the transmitter. If the
EEPROM is blank, the Fault Log will register EEPROM_DEF
which means it loaded the default settings for the EEPROM (shown
in Table 5-1). Reset the Fault Log.
STEP 7 All of the parameters in Table 5-1 are editable from the Diagnostics
Display and should be set to the values listed on the Factory test
Data sheet not necessarily the default values listed. If the Factory
Test Data is not available or you are not sure that the values in the
Factory Test Data are still valid then verify, and where necessary,
change the values to those listed in Table 5-1. (To edit any of these
screens, press and hold [D] and then press [C]. The edit controls
should appear on the screen).
STEP 8 Press the HIGH ON button and then quickly press and hold the
LOWER button for 10 seconds. This will turn the transmitter on at
zero power output.
STEP 9 Proceed to “System Configuration and Calibration”.
