WOODWARD 9907-1200 Servo speed governor

Power up characteristics The Conditional Power-up From Flash feature works the same as in previous Rx3i CPUs: that is if the configuration is configured for “Conditional – Flash” and the Energy Pack is disconnected or has failed, the contents of flash will be loaded into RAM at power up. The CPU’s logic and configuration source and operating mode at power-up are in accordance with the tables on pages 4-14 and 4-15 of GFK-2222, where “memory not preserved” means that the Energy Pack is not connected or not working. The contents of those tables apply as follows:  All entries in the “Logic/Configuration Source and CPU Operating Mode at power-up” table which address “Logic/Configuration Power-up Source in User Memory” apply to Logic/Configuration as if there were a battery.  The condition of “Memory not preserved (i.e., no battery or memory corrupted)” is created on a CPE310 by power cycle with the Energy Pack removed.  The condition of “No configuration in User Memory, memory preserved” is created on a CPE310 by clearing configuration (or never downloading configuration), and then cycling power with the Energy Pack connected.

Energy Pack Replacement

 If an Energy Pack fails, you can replace it with a new unit while the CPU is in operation. When an Energy Pack is replaced, the new Energy Pack must charge. If a loss of power occurs while the Energy Pack is disconnected or before it is fully charged, a memory loss may occur.

 The conditions for Logic/Configuration source of “Always Flash,” “Conditional Flash” and “Always RAM” are created by setting the appropriate configuration setting in the CPE310 and cycling power with the Energy Pack connected.  User memory is preserved only if the Energy Pack is connected (and charged) at power-down. Similarly, user memory is preserved only if the Energy Pack is present at power-up.  The user memory is preserved on a CPE310 by an Energy Pack connection at the instant of power-down and the instant of power-up. Removing or reconnecting the Energy Pack while the CPE310 is not powered has no effect on the preservation of user memory.
