COPELAND™ COMPRESSOR ELECTRONICSDIGITAL MODULATION EXTENSION MODULE D – QUICK INSTALLATION GUIDE
Copeland™ Stream with Copeland™ Compressor Electronics provides advanced motor protection, diagnostics and digital control and unloaded start as an option via the Digital Modulation extension module D.Module D controls the operation of:▪ the digital modulation over a voltage input (D5/D6) or Modbus;▪ the unloaded start by compressor start signal (terminals 17/18) or Modbus.
Installation of Digital Modulation & Unloaded Start extension module D
The Digital Modulation & Unloaded Start extension module D can be ordered under reference N°3281571 and used on Stream compressors equipped with Copeland Compressor Electronics.Module D is automatically detected when inserted.Switch off/on Copeland Compressor Electronics before/after inserting the module into its dedicated slot.Module D is to be inserted into the slot located in the middle right of the module as shown in Figure 2 below. The correct slot for the Digital Modulation & Unloaded Start extension module is marked with the letter D.
