Description
1.0
The installation and operating instructions in this manual apply to both the standard Smart Pass-Through and the
Smart Pass-Through, which features a non-outgassing, potted polyurethane door seal. The standard model uses an “e”-
shaped, heat-formed gasket to seal the doors.
The Smart Pass-Through series includes an electronic interlock which allows only one open door at a time, thus minimizing the
amount of “dirty” air that can enter the cleanroom. This interlock system is operated by an integral Smart Controller, which
features indicator lights and alarm bells as standard equipment. The Smart controller can also be equipped with any number of
Smart Pass-through™ accessory modules, expanding its capabilities to include UV sterilization, air showers, load presence
sensors, data-logging, and a host of high-tech security features.
The operator should always verify the opposite door is fully shut prior to opening a door. Do not yank,
shake, or apply excessive force to the doors. Attempting to force open a door while the interlock is
engaged may result in damage to the unit.
CAUTION
Smart Door Interlock™
Terra Universal’s Smart Pass-Through™ chambers are equipped with electronic interlocks to
prevent the opening of both doors simultaneously. When one door is open, the other will remain
locked until both doors have been closed.
This cross-contamination protection is accomplished using an internal Smart Pass-through
Controller built into the body of the pass-through chamber. The unit arrives from the factory pre-
programmed to control the door interlock system, alarm bells, and any Smart Pass-through™
accessories specified in the order.
