Master Catalog 125 Pressure Controls Section P Installation Bulletin P100 Issue Date 1018 © 2018 Johnson Controls 1 Part No. 24-7664-2047, Rev. B www.penncontrols.com Code No. LIT-125511 A pplication The P100 Series Encapsulated Pressure Controls are compact, economical, direct-mount, snap-action, On/Off pressure controls, available in a wide variety of factory-calibrated, non-adjustable pressure setpoints. The P100 controls are designed primarily for direct or pilot duty control of motors and other refrigeration or air conditioning application loads requiring precise, repeatable pressure control over a wide range of ambient conditions. Standard P100 models come with 1/4 in. SAE female flare fitting with integral Schrader valve depressor and 48 in., No. 18 American Wire Gauge (AWG) insulated, stranded-copper wire leads. See Figures 2 and 3. The standard P100 models are UL Recognized as refrigerant pressure limiting devices. A high pressure manual reset lockout is available on some models. See Figures 1 and 2 for standard models available from your Johnson Controls®/PENN® sales representative. Additional pressure connection styles, pressure setpoints, and electrical ratings are available on non-standard models, in quantity orders only. Contact your Johnson Controls/PENN sales representative or distributor, or Refrigeration Application Engineering at (800) 275-5676 to order non-standard P100 pressure controls. O peration A bowed, stainless steel, snap-acting disc reverses its curvature when pressurized to the specified actuation setpoint. When the disc snaps, it drives a set of electrical contacts open or closed, depending on the control’s switch action. When the applied pressure returns to the specified deactuation setpoint on automatic reset controls, the snap-acting disc and electrical contacts return to their original position. On high pressure manual reset controls, the disc remains in the reversed position and the electrical contacts remain open until both the deactuation pressure is reached and the manual reset button is pushed. After deactuation pressure is reached, push the manual reset button to return the contacts to the closed position. A “trip free” internal latching mechanism on manual reset controls does not allow the control to be reset until the system pressure reaches the specified deactuation setpoint, even if the reset button is held fully depressed.

Observe the following guidelines when installing the P100 controls. IMPORTANT: If these controls are installed on equipment containing hazardous or regulated materials, such as refrigerants or lubricants, the installer and user should observe all regulations governing the handling and containment of those materials. IMPORTANT: Pressure tap points should be located on the top side of the refrigerant lines. This reduces the possibility of sediment accumulating in the control. Do not overtighten flare nuts on pressure connection fittings. Overtightening flare connections may damage the threads on the flare nuts or flare connectors and result in refrigerant leaks. Do not exceed 9 lb . ft (12 N . m) of torque when tightening brass flare connections. Avoid severe pressure pulsation on high-side pressure connections. Install P100 controls on pressure tap points away from the compressor discharge to minimize the effects of pressure pulsation from reciprocating compressors. W iring WARNING: Risk of Electrical Shock. Disconnect the power supply before making electrical connections. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. AVERTISSEMENT: Risque de décharge electrique. Débrancher l'alimentation avant de réaliser tout branchement électrique. Tout contact avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles. IMPORTANT: Make all wiring connections in accordance with the National Electrical Code and all local regulations. Use copper conductors only. Do not exceed the control’s electrical rating. Standard P100 Encapsulated Pressure Controls are available with several switch options. Check the label on the control body for model number. Refer to the following guidelines, diagrams, and the electrical ratings in Table 1 and Table 2 when wiring the standard P100 controls. L1 L2 Load Open-high switch action: opens on pressure rise. L1 L2 Load Open-low switch action: opens on pressure drop. Figure 3: Wiring diagrams for P100 control models with a SPST switch ! P—P100 Series Encapsulated Pressure Controls Installation Bulletin 3 IMPORTANT: After mounting and wiring control, attach a reliable set of gauges to the controlled equipment and operate the equipment at least three cycles at the pressures necessary to verify control setpoints and proper operation. Do not exceed manufacturers’ recommended pressure ratings for the controlled equipment or any of its components when operating the controlled equipment. R epairs and replacement Field repairs to the P100 pressure controls must not be made. For a replacement control, contact an authorized Johnson Controls/PENN sales representative or distributor, or Refrigeration Application Engineering at (800) 275-5676. O rdering information Standard P100 control model features are available in single and quantity orders through your Johnson Controls/PENN Sales Representative or Distributor. Non-standard P100 controls, built to customer specifications, are also available (with quantity orders only). Contact your Johnson Controls/PENN sales representative or distributor, or Refrigeration Application Engineering at (800) 275-5676 for ordering non-standard P100 pressure controls.
