CHAPTER 7:
ELECTRICAL PANEL ASSEMBLY
7.1
Overview
The Electrical Panel Assembly uses a micro Programmable Logic Controller, Motor Starter, trans-
former and switches manufactured by Telemecanique. This controller model is called TWIDO. The
control system will provide logical control and safety shutdowns for the compressor equipment. All
necessary time delays, counters, shutdowns, sequencing and safety features are incorporated into a pro-
prietary program permanently saved into PLC memory using EEPROM technology. There are normally
six PLC programs used in this Electrical Panel Assembly, based on the pressure and use of the com-
pressor. The program version used can be identified by the white sticker on the face of the PLC. The
panel is pre-wired and fused for the horsepower and voltage of the compressor. Active Power mainly
uses 460 volt, 3 phase, 60 Hz supply.
