Replacing a module in a 2-module system
Special attention is required when replacing a module in 2 modules/1 driver
conguration. Due to the fact that the driver can only read out information from a
single module, in case of failure we recommend replacing both modules, as current
settings can vary from batch to batch over time as LED performance improves. If
the installer does not replace both modules it is possible that one of the modules
will be driven at the wrong current and will not produce the specied lumen
output. Production date code on the module label identies the batch.
Using a long cable in combination with the Fortimo LED HBMt system
It is possible to use a connection between module/s and driver longer than the
standard 60cm cable. When using AWG24 cables, the connection can be extended
up to 10 meters without affecting the power supply to the module. It is not advised
to use the communication wires because of possible interferences.
• Do not use Rset - output current needs to be programmed in the driver
• Module Temperature Protection (RNTC) function cannot be used
• Do not use the Common wire
• Design-in support is available; please contact your Philips sales representative
Warning!
When using a long cable between module
and driver, extra care should be taken in the
design of EMI, surge and noise suppression
