ke2 compressor sequencer oem · aux relay board 21323 auxiliary relay board external relays 21304...

Product Summary:The KE2 Compressor Sequencer OEM allows control of up to 8 stages of loading for a single suc-tion group, or up to 10 stages of loading (5 per suction group) for dual suction groups.

For dual suction groups, the controller is applicable to both racks with a shared common dis-charge, or independent discharge lines. Suction pressure can be controlled to either a fixed setpoint, or a floating suction pressure for maximum efficiency.

Each stage of loading can be set to: fixed speed compressor, variable speed compressor①, digi-tal compressor① ② or unloaders. The relays for the stages can alternatively be used to control a Master Liquid Line Solenoid, or as a Hot Gas Defrost Relay.

Communication:As is standard with many other KE2 Therm controllers, the KE2 Compressor Sequencer OEM has the simplest and easiest communication platform in the industry. The controller uses standard communication protocols and cables; no extra software is necessary, only an Ethernet connec-tion to the controller. E-mail and/or text alerts can be sent out right from the controller. Com-plete remote access is available during startup with one simple button press and an Internet connection.

① One per Suction Group

② Controller is designed to operate with a Copeland Scroll Digital Compressor, when Digital Compressor is selected.

Running the SystemIMPORTANT: All of the settings on the Setpoints page should be reviewed before beginning operation (See pages 26 - 28 for detailed explanation of each Setpoint).

When the KE2 Compressor Sequencer OEM is started for the first time, or anytime a critical setpoint is changed, the controller enters System Off mode.

In System Off mode, the controller will not energize any relays until the user manually takes the controller out of System Off.

Once all setpoints have been reviewed, and the system is ready to be-gin operation, click the yellow button on the setpoints

page to begin running.

The button will change to and begin operation.

Clicking this button again will put the system back into System Off.

Note: When two suction groups are used, there will be two Setpoints pages, one for each group. Click the icon to go to the Setpoints page for that suction group. Each suction group is individually put into, and taken out of, System Off.

Please make sure to review the Setpoints page of BOTH suction groups.

Press and hold until the screen goes back to SYS, SY1 or SY2.

The suction group will now be in System Off, or running, depending on what was selected.


Q.2.60 March 2019


Quick Start Guide

When applying the controller to a system consisting of fixed speed compressors with or without unloading capabilities, the controller requires the user to assign a relay output for each compressor stage available using the controller’s browser interface.

When Fixed Suction Pressure and only Fixed Speed Compressors are selected the controller will stage the compressors by capacity in HP as defined on the Setpoints page or Aux Relay Board Setpoints page. Stages will be loaded and unloaded based on the smallest ca-pacity step available. If all available stages are equal, the controller will automatically select the option with the least amount of runtime.

The Suction Pressure Setpoint is the target pressure the controller works to achieve while running. The Suction Pressure Differential determines the pressure above and below the Suction Pressure Setpoint the controller will allow the suction pressure to vary before it makes an adjustment to capacity.

Once a stage has been loaded or unloaded, that stage must remain on or off as determined by the Min Comp Runtime and Min Comp Offtime. The controller will not load or unload more often than the time defined in the Min Compressor Switch Time.

If the system is maintaining the suction pressure within the normal operating range, which is defined as the Suction Pressure Setpoint +/- the Suction Pressure Differential, it will maintain the current capacity.

Mode of Control: Fixed Suction Pressure & Fixed Speed Compressors

Determining Compressor ON/OFF Order

Mode of Control: Fixed Suction Pressure with Digital Scroll or Variable Speed Compressors

When applying the controller to a system consisting of fixed speed compressors with or without unloading capabilities and one digital scroll or variable speed compressor, the controller requires the user to assign a relay output for each compressor stage available using the controller’s browser interface.

The Digital Scroll or variable speed compressor will serve as the pri-mary stage to provide the most consistent suction pressure possible. Initially, the Digital Scroll will start unloaded, or the variable speed compressor will run at the Min Speed setpoint.

If suction pressure rises above the Suction Pressure Setpoint, the Digital Scroll will be loaded by de-energizing the bypass solenoid or the variable speed compressor will be loaded by increasing the 0-10VDC output (0-5VDC also available). The rate at which the Digi-tal Scroll or variable speed is loaded is determined by the controller’s algorithm, and will improve as the controller learns the system. If the Digital Scroll or variable speed compressor is fully loaded, the next stage will be loaded based on the smallest capacity step available. If all available stages are equal, the controller will automatically select the option with the least amount of runtime. The compressors will continue to be loaded until all compressors are running at full load.

If suction pressure falls below the Suction Pressure Setpoint, the Digital Scroll will be unloaded by energizing the bypass solenoid, or the variable speed compressor will be unloaded by decreasing the 0-10VDC output. If the Digital Scroll or variable speed compressor is fully unloaded, the next stage will be unloaded based on the smallest step available. If all available stages are equal, the controller will au-tomatically select the option with the most amount of runtime. Suc-tion pressure will primarily be controlled by loading and unloading the Digital Scroll or variable speed compressor. If suction pressure is still low, and all other stages have been unloaded, the Digital Scroll’s compressor relay will be de-energized if minimum run, off and switch times have been met. For variable speed compressors, the 0-10VDC output will unload down to the Min Speed setpoint①.

① The Digital Scroll and variable speed compressor’s requirements for unloading follow their own rulesets and are not adjustable. It has been designed to be within the limits of the compressor manufacturer, and to ensure that specification is maintained the minimum times for transi-tioning are not adjustable.

The KE2 Compressor Sequencer OEM has the ability to float the tar-get suction pressure for maximum efficiency. When the Fixed/Float Suction setpoint is set to Float Suction, all Room Temperature sen-sors connected to a group will be compared to the Room Temp set-point on the controller. When the average of the Room Temperature sensors is below the Room Temp setpoint and above saturation tem-perature, the controller will raise the target suction pressure. When the average of the Room Temperature sensors is above the Room Temp setpoint, the controller will lower the target suction pressure.

While floating suction is enabled, the Suction Pressure setpoint be-comes the minimum suction pressure that the controller will work to maintain.

Mode of Control: Floating Suction Control
