NVRAMS
User programming information and critical operating parameters of the AM2020/AFP1010 system are stored in Nonvolatile
Random Access Memory (NVRAM). Improper cycling of power to the AM2020/AFP1010 can cause the NVRAMS to
become inaccessible. The AM2020/AFP1010 software now verifies the state of the NVRAMs. If a NVRAM problem has
been detected, the AM2020/AFP1010 will display one of the following two error messages depending on where the problem
is located:
Other indicators of NVRAM problems by board are:
Board
SIB-NET
The correct power down procedure is to remove battery power, then disconnect primary power (AC) at the circuit
breaker in the electrical distribution panel, then wait at least one minute before disconnecting or connecting any cables
or circuit boards, or reapplying primary power. The correct power up procedure is to connect primary power, then
connect the battery, and wait one minute before taking any further actions, especially pressing the acknowledge button,
which can cause NVRAM problems if pressed during the first minute after power application.
If this condition occurs, call the factory for immediate assistance.
