Replace Module - GE T60 Instruction Manual

CHAPTER 10: MAINTENANCE
8. If you changed the Remote Setting Authorized, the Local Setting Authorized settings, or relay lock settings, return
them to their previous settings.
9. To apply any previously saved settings, right-click the saved settings file in the Offline Window area and select Write
to Device.
The field-programmable gate array (FPGA) can be upgraded under Maintenance > Update FPGA when the device
is connected via serial cable and the firmware revision is 7.0 or higher.
Modbus addresses assigned to firmware modules, features, settings, and corresponding data items (that is, default
values, minimum/maximum values, data type, and item size) can change slightly from version to version of
firmware. The addresses are rearranged when new features are added or existing features are enhanced or
modified. The EEPROM DATA ERROR message displayed after upgrading/downgrading the firmware is a resettable,
self-test message intended to inform users that the Modbus addresses have changed with the upgraded firmware.
This message does not signal any problems when appearing after firmware upgrades.

10.9 Replace module

This section outlines how to replace a module.
Withdraw or insert a module only when control power has been removed from the unit, and be
sure to insert only the correct module type into a slot, else personal injury, damage to the unit or
connected equipment, or undesired operation can result.
To avoid damage to the equipment, use proper electrostatic discharge protection (for example, a
static strap) when coming in contact with modules while the relay is energized.
The relay, being modular in design, allows for the withdrawal and insertion of modules. Replace modules only with like
modules in their original factory configured slots.
To replace a module:
1. Open the enhanced faceplate to the left once the thumb screw has been removed. This allows for easy access of the
modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens completely and
allows easy access to all modules in the T60.

The standard faceplate can be opened to the left once the black plastic sliding latch on the right side has been pushed
up, as shown below.
