Contact 22AWG
Contact Rating 10VA
Contact Type Normally Open
Max Carry Current 2 Amp
Max Switching
Current .5 Amp
Breakdown Voltage 250 VDC
Operating Gap 2 inches (5 cm)
Temperature Range 32°F to 120°F (0°C to 49°C)
Housing Material solid aluminum housing
Cable Length 24” (61 cm) stainless steel armored cable
Certications UL and ULC listed
Basic Description
Designed to withstand rugged
high trac installations, the door
switch provides increased energy
eciency, more stable product
temperature, and is eective at
preventing coil freeze ups. The reed
switch is hermetically sealed with
a PVC shock absorber, enclosed
within a solid aluminum housing.
Installation wires are protected in a
24” (61 cm) stainless steel armored
cable. The magnet is mounted on
an adjustable L shaped bracket
providing greater exibility,
universal mounting, higher pulling power, and a professional
appearance.

Mounting the Door Switch
The door switch mounts in any position along the door, how-
ever the gap between the magnet Aand the contact assembly/
sensor Bcannot exceed 2”(5 cm) when the door is closed.
If the gap is greater than 2” (5 cm) the door switch will contin-
ually signal that it is open, and the controller will turn o the
evaporators. To help the installer adjust the gap, the L-bracket
has Cmultiple mounting holes, and the magnet can moved
forward, or backward, in the slot D.
Position
Controller Operation with Door Switch Activated
Normal system operation while the door is closed.
When the door is opened, evaporator fans are turned o.
If the door is left open for longer than 60 seconds, the sole-
noid (EEV) is closed to initiate system pumpdown.
System will remain in pumpdown until door is closed.
If the door is left open for time set in Door Alarm Delay (de-
fault is 30 min.) and the temperature rises 5°F (2.8°C) above
setpoint, a Door Alarm is activated and the system is turned
back on to resume cooling
Once the door is closed, normal system operation resumes.
The magnet can mount to the
inside of the L-Bracket or the
outside.
The Contact Assembly / Sensor mounts in any
postion,as long as it is within two inches of the
magnet, when the door is closed.

2. On the controller’s web page, select Setpoints from the Home Page.
3. Select Login to make Setpoint changes.
4. Enter the User Name ke2admin and the Password ke2admin* and
press Enter (Return) on your keyboard or click the Submit button on
the bottom right of the screen.
*For security purposes, the User Name and Password can be changed from
the factory default under the Settings Page.
5.Set Digital Input Mode to Door Switch from the dropdown menu.
6.Set Digital Input State to active when Open from the dropdown
menu. Note: This can be set to Closed for a Normally Open door switch.
7. Click Save.
8. If the door is left open for the time set in Door Alarm Delay, an alarm
is activated and the system resumes cooling. Adjust the Door Alarm De-
lay based on your typical delivery timeframe.

Setting the KE2 Evap, KE2 Evap for Rack Eciency, or KE2 Controlled Environment for use with a door switch.
1. Wire door switch (dry contact) to a Digital Input. (Further information
is found in Quick Start installation guide that shipped with the controller.)
Door switch wires may be extended.
NOTE: Screen shots shown are representative of the procedure. They will vary slightly based on the controller being installed, and
on the version of rmware. Any dierences are irrelevant when installing a door switch.

1 T1 and T4 are parameters that
can be set to various functions.
The default for T1 is Suction
Temp, the T4 is Coil Temp.
2 The Setpoint paramenters
shown in BOLD (Valve Type,
Room Temp Setpoint and
Defrost Mode) need to be set by
the user prior to start up. The
other Setpoint Parameters can
also be adjusted, however the
factory setpoints are generally
correct for most applications.

in ITALIC are only displayed
when a Custom EEV is used.
4 Displayed when an EEV is used.
5 Only available if mechanical
valve is selected. When using an

Setting up the controller for use with a door switch using the controller’s display
KE2 Low Temp + Defrost & KE2 Adaptive Control
1. Press and hold the BACK button to access the ADVANCED MENUS
2. Using the arrows, navigate to Setpoints, then nd AU2* (Auxiliary In-
put 1), short press ENTER, change setpoint, then press and hold ENTER
for 3 seconds
NOTE: The navigation shown is representative of the menu. They menu will vary slightly based on the controller being installed, and
on the version of rmware. The basic controller navigation remains the same for all.
3. Then press down until StA2 (Digital Input Active State) is displayed,
press ENTER, then press down to change to OPEN, press and hold ENTER
for 3 seconds.
*We recommend using AU2, as AU1 is factory set as a second coil sensor
input on the KE2 Adaptive Control.
KE2 Therm has videos on door switch installation on our YouTube
channel, at YouTube.com/ke2therm. In addition, we have videos
on controller installation, programming, and troubleshooting.
