DIGITAL MODULATION EXTENSION MODULE D – QUICK INSTALLATION GUIDE
1 Introduction
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.
2 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.
