SLX Series
12. Memory Erase Jumper
Each controller features a memory erase jumper that can be
used to erase the Neuron chip’s memory. If an incorrect APB
file is loaded into the controller, the Neuron chip's memory will
be corrupted and no communication with the controller will be
possible. The memory erase jumper can be used to correct this
problem by resetting the Neuron chip’s memory; the chip will
then be in an application-less state. The memory erase jumper
is labeled J5.
To erase the Neuron chip's memory using the memory erase
jumper, do the following:
1. Disconnect the power to the controller.
2. Place a jumper on the pins labeled J5 on the controller.
Figure 20: Memory Erase Jumper Location (J5).
3. Reconnect power to the controller.
4. The orange-colored service LED will blink rapidly indicating
that it is erasing the Neuron chip's memory. When the
service LED stops blinking and remains solid, the erase
procedure is complete. The erase procedure typically takes
between 2 and 10 seconds.
5. Disconnect the power to the controller and remove the
jumper.
6. Reconnect the power. The service LED will blink twice and
become solid indicating that the controller is application-
less.
The proper APB (using the
Commission
or
Load
option in
LNS, e.g. SLX Series LMT) can now be loaded into the
controller.
13. Maintenance
Due to
HIGH VOLTAGE
, direct contact will
cause electrical shock or burn. Turn off power
before any kind of servicing.
The PFCU and PTU controllers require minimal maintenance,
but it is important to take note of the following:
-
If it is necessary to clean the outside of the front plate
and/or the inside of the back plate, use a
dry
cloth.
-
Verify the tension of all wires and cables whenever the
controller is serviced.
14. Disposal
The Waste Electrical and Electronic Equipment (WEEE)
Directive sets out regulations for the recycling and disposal of
products. The WEEE2002/96/EG Directive applies to
standalone products, i.e. products that can function entirely on
their own and are not a part of another system or piece
of equipment.
For this reason, SLX Series products are exempt from
the WEEE Directive. Nevertheless, SLX Series
products are marked with the WEEE symbol, indicating that
disposal of the devices shall not be done together with
municipal waste.
Products must be disposed of at the end of their useful life
according to local regulations and the WEEE Directive.
