After 3/03, the sensor is located in the inlet cone (as shown in the diagram). Before 3/03, the sensor was located in the suction elbow. 6 Beginning 3/05 the CS05 sensor was redesigned to use a well. The location remained the same. From 3/03 to 3/05 no well was used. 7 This cable was used with the original operator interface panel. The new flat screen panel uses a VGA cable and a serial cable which comes with the panel. RPL / Page 33

It is factory installed and wired when code 33= E (evaporator only), C (condenser only) or B (both condenser and evaporator). The switches used for either the MicroTech 200 or the MicroTech II control types are the same as are the wells. However the schematic designations are different. MicroTech 200 units designate the Evaporator & Condenser switches as CHW1 & CH1, while the MicroTech II units designate the same switches as EF1 & CF1. The only component part number difference of note are the power cables. N/S= Not Shown on diagram. *Quantities are based on the presence of both DPS (Code 33= B). If code 33= E or C part numbers 651 & 656 quantities are 1 & 4 respectively, and only one cable (411 if C33= E or 412 if C33= C) is used. If only one DPS is used, the well (ref. # 667) has a quanity of (used on the vessel with the DPS) and (used on the vessel without the DPS). Differential Pressure Switch- None (Code 33= Y) Wells Ref.
