Non-replaceable Parts
Other than the parts listed in the replacement parts sections, there are no
serviceable components on the base assembly.
Memory
Any addition, modification, or replacement of memory components requires software
configuration and is not a field upgrade. For additional information on modifying the
memory capacity of the controller, consult your regional Tridium office.
Fuse
The controller contains a non-user replaceable fuse, soldered on the circuit board.
This fuse provides protection from internal shorts or connection to incorrect power
supplies. If the fuse circuitry is suspect, contact your regional Tridium office for
technical support. See the “Returning a Defective Unit” section on page 31.
Standard Replacement Parts
Standard replacement parts are listed in Table 4 , and can be ordered from stock
without restriction. Standard replacement parts cannot be returned for credit and
should be disposed of in an appropriate manner.
New Replacement Unit
To replace an entire unit, order and install a new T-300E or T-600E controller. If the
faulty controller is still in warranty, you can receive credit by returning it. Be sure
to contact the vendor for a return authorization (RA) number before shipping an
item for return credit. See “Returning a Defective Unit,” page 31, for more details.
Note Before ordering a new controller, it is strongly recommended that you
contact your normal technical support resource to eliminate the possibility
of a software issue or mis-configuration problem.
Replacing the Controller Base Assembly
Note Before handling circuit boards, discharge any accumulated static by
touching a nearby earth ground. For details, see the “Static Discharge
Precautions” section on page 6.
