Application
Multiple Fan Operation
♦ All drives operate as variable speed for maximum energy saving.
♦ Equal run time sharing across each fan / fan bank.
♦ Automatic system reconfiguration in the event of a fan fault.
♦ Continued system operation when drives are individually powered off.
♦ Communications and +24V control voltage shared between drives via a standard RJ45 patch lead.
♦ Independent maintenance indicators for each fan bank.
♦ Any fan bank can be switched to hand operation at the touch of a button and will automatically rejoin the network when switched back to auto.
