Reset Types

There are three ways to reset a safety device.
Reset type
Emulate cycling power.
Return to the out-of-box configuration, and
then emulate cycling power.
Return information except for specified
parameters to the out-of-box configura-
tion, and then emulate cycling power.
The safety device stores the following information in the nonvolatile memory of the device:
Type
Device parameter
Node address (soft-
ware setting)
Baud rate (software
setting)
TUNID
(Target Unique
Node Identifier)
Password
CFUNID
(Configuration Own-
ing UNID)
OCPUNID
(Output Connection
Point Owning UNID)
The information above is stored in the nonvolatile memory of the device, and so it is not cleared by cycling
the power source once it is set. To clear the information (to return to the default settings), select Return to
the out-of-box configuration, and then emulate cycling power or Return to the out-of-box configuration except
to preserve the following parameters, and then emulate cycling power.
Failure to clear the previous configuration data before connecting the device to the network
may result in loss of safety functions, personal injury, or death.
