Initial Device Loading
Allow the device to operate at the desired temperature for a minimum of 4 hours before loading. If stocking ambient
temperature products, load the device one shelf at a time, beginning with the top shelf. After loading each shelf,
allow the device to recover to the desired set point before loading the next shelf. Repeat this process until the
device is fully loaded.
Access Verification
Present a valid access pass to the left of the LCD display on the front panel. The LCD display text should indicate
that the door is now unlocked. The door can be closed at any time and will relock automatically. This can be verified
by gently pulling on the door handle.
Remote Alarm Contacts
Alarm contacts on the back of the device are available to wire the device into an alarm system. These contacts
alarm on high/low temperature, power outages, and control probe failures.
Third-Party Temperature Systems
The device is equipped with a probe access port for using any third-party temperature monitoring system.
Remove the white caps from back of unit and run the probe through to the interior. The port location is indicated
with a label. Seal the hole with putty to prevent outside air from getting into the chamber. Mount the probe inside the
device near the label location. Refer to the probe install guide for details. DO NOT run a probe across the door
gasket as it may cause excessive condensation or a frosted evaporator.
Operating Instructions
Temperature Controller
The digital temperature controller is designed to provide full temperature control of the device. The controller also
provides a constant readout of the sample temperature inside of the device. Keypad buttons allow the user to easily
select the display units, set point, and alarm information.
The controller has been factory set and tested to allow your device to operate at its desired temperature cycle.
Please consult the manufacturer’s documentation for additional instructions on using the temperature controller.
Adjusting the settings on the controller will override the factory settings. It is recommended to consult with Terso’s
technical support department prior to adjusting controller.
Basic Access Process
An end user will present an access pass to the pass reader on the device. The access pass needs to be presented
close to the pass reader to be read. The LCD display will indicate granted access when a valid access pass has
been presented.
The user now can open the door for a configurable time period, normally about five seconds. Otherwise, the user
will need to present the access pass again. Once unlocked, the desired products may be added or removed. The
device will give an audible alarm if the door is left open for more than one minute or configured alarm time.
Once products have been added or retrieved close the device door. The door will automatically lock, and the
inventory process will begin and take about a minute to complete. The resulting updated inventory will then be sent
to Terso Solutions for processing. The device will not be accessible during the inventory process. Access will then
be restored, and the process can be repeated.
