Power Series Backup
There are three prompts which allow the user to manipulate the
EEPROM contents: Backup Data Set, Default Data Set, and Restore
Data Set. Each of these prompts have a choice of
[`all] , [`sys] ,
[2n`1] , [2n`2] , or [2n`3] .
There are two sets of data stored in the controller; the first is the
User EEPROM and it is what is read on every power on. The
second is the Backup EEPROM.
The Default Data Set prompt will update the chosen configuration
parameters in the User EEPROM to values that are listed in the
manual as default. It will update the chosen input and retransmit
calibration parameters in the User EEPROM to the values that are
stored in the Backup EEPROM by the factory.
The Backup Data Set prompt will update the chosen configuration
parameters in the Backup EEPROM from the current values stored
in the User EEPROM. It will NOT overwrite the calibration
parameters.
The Restore Data Set prompt will update the chosen configuration
parameters in the User EEPROM from the current values stored in
the Backup EEPROM. It will NOT overwrite the calibration
parameters.

It’s likely the heater is too wet for heater bakeout time selected. Increase
heater bakeout time, cycle power to restart heater bakeout process.

Check output with test instrument while Power (%) [`Out] is at
[``)0] . If there is an output, return to the factory for a new SCR. If
there is no output, check current calibration.

Line voltage is losing half cycles or SCR is not gating properly. If
load is inductive, increase
[rdLY] until error no longer occurs. Cycle
control power to clear error.
Yes No 195 r, (256)
Three phase power is connected with incorrect phasing. Swap any
two incoming phases. Cycle control power to clear error message.
Yes No 195 r, (64)
Provide more cabinet ventilation or cooling. Check the fan; if faulty,
return to factory for repair. Check to see that the heat sink is clean.
Cycle control power to clear error. Return to factory for SCR voltage
