RELATION OF LOCAL MODE TO REMOTE
MODE OPERATIONS
(1) Input of Local Control panel switch is only effective when POWER lamp is in "LOCAL"
mode. (POWER lamp is FLASH.)
(2) When the POWER lamp is in "REMOTE" mode (POWER lamp is ON), "REMOTE" input
signal only is effective under initial status.
(3) When the POWER lamp is in "REMOTE" mode (POWER lamp is ON),
The operation mode is shifted to RS-485 ON-LINE in response to ON LINE request of
operation mode command from RS-485 communication port, only operation by the
operation request command from computer is effective.
(4) RESET button input and "RESET" signals are all-time effective.
(5) When the mode is shifted to "LOCAL" under ON-LINE operation mode, the operation
mode is force-shifted to LOCAL.
(6) Commands other than operation commands are all-time effective, and the power supply
unit sends back an answer message to computer. In addition, event commands are alltime
sent against event occurrence.
