GE Mark VIeS - Configuration (Modes)

7.12.2 Configuration (Modes)
Channel configuration can be done at any time, but requires a channel be taken from an Unused mode to an assigned mode (or
from an assigned mode to Unused), but not directly from one mode to a different mode. This does not require a device reboot
or impact adjacent channels.
The YUAA allows changing individual point configuration though an Online Load (parameter download without rebooting)
without affecting any other point, however changing from any one type of point to another first requires that the point be
configured as Unused. The product will protect against an invalid transition and will fail the download and issue a diagnostic
alarm to indicate the issue.

Caution
To prevent damage to the SUAA, when the PWR_RET terminals are serving as a
ground return for the channel, verify that the current to the ground is limited to 50
mA or less. If the ground path is capable of higher currents, then an external series
resistor should be inserted in series with the terminal connection to serve as a current
limit. As an example, if a 24 V circuit was capable of being incorrectly wired to the
PWR_RET terminal, then a 510 ohm 2 watt resistor would be used in series as a
protection device.
Caution
To prevent damage to field devices, verify wiring prior to configuring the I/O pack.
Avoid any incorrectly wired channel that could act as an output driving back into an
analog input device. The I/O pack is capable of acting as an output or input channel
under software command. The terminal blocks are in groups of 3 screws to allow for
channels to be attached one at a time as part of wiring checks.
