KE2 WiFi Service Tool(pn 20906)
KE2 LDA (pn 21253)
Application:▪ Designed for small to mid-sized racks - eliminates overly
complicated controls that are designed for larger systems.
▪ Easily applied to new or existing installations.
▪ Supports up to 5 stages of loading with onboard relays.
▪ On racks with compressors all of equal HP, will automatically equalize runtime
▪ Racks with compressors of varying HP, it maintains consis-tent suction pressure.
▪ Master View webpages, allows technicians to quickly and easily assess the system’s operation & Review historical per-formance using onboard data logging.
▪ Works as a stand-alone rack controller or in conjunction with KE2 Evaporator Efficiency controllers.
▪ Can limit the amount of defrost load, as dictated by the site’s electrical requirements.
The KE2 Compressor Sequencer is new to KE2 Therm’s refrigeration con-trols suite. Designed for small to mid-sized racks, The KE2 Compressor Sequencer brings the controller’s features in line with the job’s require-ments. It eliminates the necessity of using overly complicated controls designed for larger systems.
The KE2 Compressor Sequencer replaces aging rack controllers or can retrofit racks with existing mechanical controls.
The controller supports up to 5 stages of loading through its onboard relays. Each relay can be configured as the rack’s: Fixed Speed Compres-sor, Compressor Unloader, Digital Scroll Compressor, Master Liquid Line Solenoid, or Hot Gas Defrost Relay.
When applied to racks with compressors all of equal horse power, the controller will automatically equalize the runtime of each compressor. Compressors can also be of various HP. When more than one HP is se-lected the controller will use the stage with the smallest capacity, to maintain consistent suction pressure.
The KE2 Compressor Sequencer includes KE2 Therm’s Master View web-pages, allowing technicians to quickly and easily assess the system’s operation, and review historical performance through onboard data logging.
The compressor sequencer works as a stand-alone rack controller or in conjunction with KE2 Evaporator Efficiency controllers. When applied with the KE2 Evaporator Efficiency controllers the KE2 Compressor Se-quencer can limit the amount of defrost load, as dictated by the site’s electrical requirements.

After receiving the System Off command the controller will turn off all but the largest capacity compressor. It will continue to run until the pressure goes below Cut Out Pressure or max Pump Out Time has been reached. If a Digital Scroll has been selected it will always be the last compressor on. The controller will maintain current System Off state until signal has been removed and pressure rises Suct Press Diff above the Suction Pressure setpoint as long as the min Comp Offtime has been satisfied

Stand Alone Operation• The controller will send a notification to the email address or phone number provided in the Address for Alerts field on the
Settings page of the controller.• The Amber LED on the front Panel will be illuminated• The controller will scroll Min Safety Suc SH across the front panel
utilizing KE2 Evaporator Efficiency controllers• The compressor sequencer will utilize the superheat of the KE2 Evap controllers with EEVs to assist in raising the superheat at
the rack using the following sequence:- Every 5 minutes the Superheat Setpoint of each KE2 Evap controller will be increased 1 degree - If the superheat is able to be maintained 2 degrees above the Min Safety Suc SH the compressor sequencer will lower the
superheat 1 degree every 5 minutes until the setpoint has returned to its original value.- Once all of the KE2 Evap controllers have been returned to their original setpoint values and the superheat reading is main-
taining above the Min Safety Suction Superheat the alarm will be cleared.• The controller will send a notification to the email address or phone number provided in the Address for Alerts field on the
Settings page of the controller.• The Amber LED on the front Panel will be illuminated• The controller will scroll Min Safety Suc SH across the front panel

KE2 Compressor SequencerQuick 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 web pages. (Maximum Stages – 5)
Once the controller setup is completed through the controller’s Mas-ter View web pages, it is ready to turn the System On, or allow Re-frigeration, by either clicking the yellow System is Off button on the Setpoints web page, or using the Manual Menu -> Manual Control option.
When Fixed Suction Pressure and Fixed Speed Compressors are se-lected the controller will use the compressor capacity in HP as defined on the Setpoints Page. Stages will be loaded and unloaded based on the smallest step available. If all available stages are equal the con-troller will automatically select the option with the least amount of runtime.
The Suction Pressure Setpoint will serve as the target pressure the controller works to achieve while in Refrigeration. The Suction Pres-sure Differential determines the pressure above and below the Suc-tion Pressure Setpoint the controller will allow the suction pressure to vary before it makes an adjustment to the compressor 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 Off-time. Stages of capacity will be made as necessary by the controller, however, it 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 Compressors
When applying the controller to a system consisting of fixed speed compressors with or without unloading capabilities and one digital scroll, the controller requires the user to assign a relay output for each compressor stage available using the controller’s web pages.
Once the controller setup has been completed through the control-ler’s Master View web pages, it is ready to turn the System On, or al-low Refrigeration, by either clicking the yellow System is Off button on the Setpoints web page, or using the Manual Menu -> Manual Control option.
The Digital Scroll will serve as the primary stage to provide the most consistent suction pressure possible. Initially the compressor will be started unloaded.
If the pressure rises above the Suction Pressure Setpoint plus the Suction Pressure Differential the Digital Scroll will be loaded by en-ergizing the solenoid.
If the pressure falls below the Suction Pressure Setpoint minus the Suction Pressure Differential it will energize the solenoid to unload the compressor. If the low pressure is maintained the main digital scroll’s compressor relay will be de-energized if the Min Comp Run-time has been met. *
If the Digital Scroll is fully loaded and the pressure exceeds the Suc-tion Pressure Setpoint plus the Differential the next stage will be loaded based on the smallest 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.
If the pressure falls below Suction Pressure Setpoint minus the Suc-tion Pressure Differential the controller will first unload the Digital Scroll. The pressure will primarily be controlled by loading and un-loading the Digital Scroll.
If that is not sufficient to bring the pressure within the normal operat-ing range, the controller will de-energize the smallest stage, or if all available stages are equal, the controller will automatically select the option with the most amount of runtime.
*The Digital Scroll’s requirements for unloading follow its own ruleset that is 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 transitioning are not adjustable.
