CM5A CONTROLLER

CM5A Unit CM5A Unit

The CM5A is a full-featured, compressor controller that incorporates analog inputs and outputs along with full PID control of suction or discharge pressure. Enhanced features provide the user with higher levels of annunciation and more detailed system information. Inputs and limits can be programmed to suit the needs of the application. Analog I/O can be used with almost any 4-20 mA pressure transducer. It is also capable of controlling scrubber liquid level using 1, 2, or 3 float switches. Touchscreen functions make it easy for the operator to make to set or change control settings.
More info on Inputs
  • Low Suction Pressure (4-20 mA Analog)**
  • High Suction Pressure (4-20 mA Analog)**
  • High Discharge Pressure (4-20 mA Analog)
  • Discharge Pressure (4-20 mA Analog)
  • Low Oil Pressure (4-20 mA Analog)
  • Low Oil Level (Digital Input)
  • Compressor Motor Aux Switch (Digital Input)
  • Oil Cooler Motor Aux Switch (Digital Input)
  • VSD Failed Input (Digital Input)
  • Excessive Compressor Vibration (Digital Input)
  • High Scrubber Level (Digital Input)
  • Open Liquid Dump (Digital Input)
  • Close Liquid Dump (Digital Input)
  • Open Bypass Valve (Digital Input)
  • Close Bypass Valve (Digital Input)
  • Master On/Off Switch/Reset Switch (Digital Input)
More info on Outputs
  • Compressor Motor Start (Relay Output)
  • Oil Motor Start (Relay Output)
  • Liquid Dump Valve Open (Relay Output) Low
  • Liquid Dump Valve Close (Relay Output)
  • Bypass Valve Open (Relay Output)
  • Bypass Valve Close (Relay Output)
  • Run Warning Indicator (Relay Output)
  • Alarm (Relay Output)
  • Suction Control Valve Open (Relay Output)
  • Suction Control Valve Close (Relay Output)
  • Compressor Motor Start (24 VDC Transistor Out)
  • Oil Cooler Motor Start (24 VDC Transistor Out)
  • VSD Compressor Speed Control (4-20 mA)
  • Input Control Valve (4-20 mA)
All programmable settings are password protected unless the password feature is turned off. Programmable settings incorporate multiple timers that give the operator flexibility control over each input. Adjustable response times can be used to take inputs out of the system, delay response to changing conditions, or prevent rapid cycling. The CM5A controller can be configured with two PID loops to control compressor speed as well as a suction pressure inlet control valve (or other device), if desired.

Special Features Available: SMS text messaging, full data logging and storage in CSV format, real time remote monitoring and control via internet.

CL1A CONTROLLER

CL1A unit

The CL1A is an easy-to-use, low-cost, single-stage compressor controller that offers features not commonly found on controllers in this price range. The CL1A includes 16 pre-programmed digital inputs and 1 analog input that can be configured as a stop/start control to work with a 4- 20 mA pressure transducer. The CL1A can be programmed for vapor recovery applications (very low pressure) or standard gas compressor applications. Output contacts are pre-programmed to control motors, scrubber dump valves, alarms, and bypass valves. Scrubber liquid level control can be achieved using 1, 2, or 3 float switches.
