Resetting - GE 845 Instruction Manual

DEVICE

Resetting

Installation
4–68
Some events can be programmed to latch the faceplate LED event indicators and target
message on the display. Depending on the application some auxiliary output relays can
be programmed to latch after the triggering event is cleared. Once set, the latching
mechanism holds all the latched indicators, messages, and auxiliary output relays in the
set state, after the initiating condition has cleared, until a RESET command is received to
return these latches (except the FlexLogic latches) to the reset state.
The RESET command can be sent from the faceplate Reset pushbutton, a remote device
via a communication channel, or any programmed FlexLogic operand. Executing the
RESET command from either source creates a general FlexLogic operand RESET OP. Each
individual source of a RESET command also creates its individual operand RESET OP (PB),
RESET (COMMS), and RESET OP (OPERAND) to identify the source of the command.
RESET INPUT 1(2,3):
Range: Off, Any FlexLogic operand
Default: Off
The setpoint selects an operand from the list of FlexLogic operands. The targets, LEDs,
and latched output relays reset upon assertion from any of the operands selected as
Reset Inputs.

DEVICE NAME
Range: Up to 13 alphanumeric characters
An alphanumeric name may be assigned to the device.
DEVICE IN SERVICE
Default: Not Ready
Range: Not Ready, Ready
The relay is defaulted to the "Not Ready" state when it leaves the factory. This
safeguards against the installation of a relay whose settings have not been entered.
When powered up successfully, the "IN SERVICE" LED becomes red. The relay in the "Not
Ready" state blocks signaling of any output relay. These conditions remain until the
relay is explicitly put in the "Ready" state.
SERVICE COMMAND
Range: 0 to 65535
Default: 0
See Password Recovery Procedure for details.
TEMPERATURE DISPLAY
Range: Celsius, Fahrenheit
Default: Celsius
Selects engineering unit of temperature display.
VALIDATE CANBUS IO
Range: NO, YES
When the relay is booted the 8 Series relay enumerates the installed IO cards
automatically. When the relay is commissioned and the Validate CANBUS IO command
is set to Yes the current auto detect value is saved to non-volatile memory. This value is
then used to configure all display dependencies and used in self-test validation.
