DIGITAL MODULATION EXTENSION MODULE D – QUICK INSTALLATION GUIDE
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.
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.
