To test an Ingersoll-Rand Xe-50M controller that is not functioning, follow these steps using the available information:

1. Check Power Supply: Ensure the controller is receiving power. If not, inspect the voltage transformer and power connections.

2. Verify Motor Rotation: If the controller shows "Ck Motor Rot", check that the motor is rotating correctly. Correct rotation is confirmed when the sump pressure reaches 1 psi or more within 3 seconds of starting (6 seconds for soft starters or if the temperature is below 50°F).

3. Check for Overload: If the display shows "Overload", inspect the motor and fan overload relays. A trip occurs if the relay is open for at least 3 seconds.

4. Remote Stop Issue: If "Rem Stop Fail" appears, confirm that the remote stop/start option is properly configured and the stop button is not stuck in the open position.

5. Inspect Communication Connections: If connecting to a MODBUS network, ensure RS-485 cables are correctly connected to port X04 and properly shielded and routed to avoid electrical interference.

If these checks do not identify the issue, further diagnostics or professional service may be needed.

Page 14: Xe-70M Controller Introduction
XE-70M CONTROLLER INTRODUCTION The Xe-70M control system is provides efficient and reliable compressor operation. The controller supports thirty languages, independently configurable units of measure as well as enhanced network and communication capabilities. This microprocessor-based controller uses a finger touch membrane for operation of the compressor and setting control parameters.
Page 15: Component Review
COMPONENT REVIEW FU1 - Main Fuse Protection FU1 is the schematic designation of the Main Fuse Protection and is the customer’s responsibility to correctly size and install. FU1 protects the machine should an overcurrent condition occur. These fuses should be time delay fuses, in order to accommodate the inrush current at machine startup.
Page 16 secondary circuits. There are two of these secondary circuits in the control system. The first secondary circuit is rated at 110 Vac, 1 phase, 60Hz and is used to energize solenoid valves and starter coils. The “hot” connection is X1 and the neutral connection, X3, is grounded to the starter chassis.
Page 17 110 Vac Circuit - Transformer (T1) to Xe-70M The Xe-70M controller receives 110 Vac from T1. Depending on operating conditions, the controller sends the voltage onward to specific areas at specific times. Examples: energizing a starter coil at start-up or energizing a solenoid valve when the compressor loads.
Page 18 SB1 - Emergency Stop Button SB1 (sometimes referred to as ES) is located next to the Xe-70M controller in the starter panel and is intended to stop the compressor in an emergency. The switch has two sets of normally closed contacts that open when the red E-Stop button is pressed.
Page 19 X01 - X13 Quick Connect Terminal Plug Strips A group of different sized terminal plugs is used to connect control and instrument wires to the Xe-70M controller. These connectors are female Phoenix type (5.08mm spacing) and plug into matching male receptacles on the Xe-70M controller.
Page 20 X02 Digital Inputs Terminal plug strip X02 is dedicated to digital inputs that provide remote control and feedback from various switches installed on the package. DI2 - Main Motor Overload Relay (FA1 R-Series Only) Connected to the bottom of KM1, the main motor overload relay provides protection in the event of an overcurrent condition in the motor windings.
Page 21 A continuous voltage is applied to the strain gauge assembly. As the strain gauge bends due to the changing pressure on the diaphragm, the resistance value through the strain gauge changes a corresponding amount; the result is a variable output signal that ranges from 0.5-4.5 volts.
Page 22 4APT - Package Discharge Pressure Connected to X03-3 & 4, 4APT has a range of 0 to 232 psi. Power is provided to the transducer at X03-3 and return signal at X03-4. The output signal is 4mA at 0 psi and 20mA at 232 psi.
Page 23 at X03-6. The output resistance is 10kOhms at 77°F and 413.9Ohms at 239°F. Should 2ATT observe the temperature rise exceeding 228°F (109°C), the controller shuts the compressor down on a Trip. The display will show the word Tripped and the Trip Log will display High Airend Discharge Temperature.
Page 24 CTO - Common Trip Outputs N.O. output connected to X07-3 & 4 X08, X09 Triac Outputs Terminal plug strips X08 and X09 are dedicated outputs that provide control of solenoid valves and starter contactors. These outputs are powered by 110 Vac located at X09-CR.
Page 25 R2 - Main Motor Start Contact Connected to X09-3, the controller provides power to KM3 main motor starter coil. Auxiliary contact KM2-1 provides full control of the Star/Wye Delta starting circuit.
Page 26 R3 - Fan Motor Start Contacts (KM4) R-Series Only Connected to X9-4, the controller provides power to KM4 fan motor starter coil. KM4 provides control of the cooling fan motor starting circuit.
Page 27 R4 - NC Load Solenoid Valve (1SV) Connected to X08-2, the controller provides power to the 1SV load solenoid valve. When energized, 1SV opens and applies pressure to the inlet valve to allow the compressor to load. R4 - NO Blowdown Solenoid Valve (3SV UP6S/RS Only) Connected to X08-2, in parallel with 1SV, the controller provides power to the 3SV solenoid valve.
Page 28 R5 - Dryer/Blower Drive Relay (KA1 TAS Option Only) Connected to X08-4, the controller provides power to the KA1 (sometimes referred to as K1) dryer/blower drive control relay. KA1 provides control of the integrated dryer or blower drive relay circuit (optional components). X10, X11 Current Transformer Analog Inputs Current transformers (CTs), if equipped, provide real-time motor current input to the controller for motor protection.

Page 30 Xe-70M Controller Interface and Operation The standard user interface configuration of the controller consists of the membrane and the LCD display. The membrane consists of five command keys (Start, Stop, Load, Unload, and Reset), four navigation keys (Up, Right, Left and Down), and an Edit mode selection key (Enter). These keys, in conjunction with the graphics display and LED icons, make up the user interface to the compressor.
