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 Eciency 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
retrot racks with existing mechanical controls.
The controller supports up to 5 stages of loading through its onboard
relays. Each relay can be congured 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 Eciency controllers. When applied
with the KE2 Evaporator Eciency controllers the KE2 Compressor Se-
quencer can limit the amount of defrost load, as dictated by the site’s
electrical requirements.

KE2 Compressor Sequencer
Quick Start Guide
When applying the controller to a system consisting of xed 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 O 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 dened
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 Dierential 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 o as determined by the Min Comp Runtime and Min Comp O-
time. Stages of capacity will be made as necessary by the controller,
however, it will not load or unload more often than the time dened
in the Min Compressor Switch Time.
If the system is maintaining the suction pressure within the normal
operating range, which is dened as the Suction Pressure Setpoint
+/- the Suction Pressure Dierential 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 xed 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 O 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 Dierential the Digital Scroll will be loaded by en-
ergizing the solenoid.
If the pressure falls below the Suction Pressure Setpoint minus the
Suction Pressure Dierential 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 Dierential 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 Dierential the controller will rst unload the Digital
Scroll. The pressure will primarily be controlled by loading and un-
loading the Digital Scroll.
If that is not sucient 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 specication is maintained
the minimum times for transitioning are not adjustable.
