CONTROL PANEL OVERVIEW Control Panel Power Switch Power is supplied and the green Power On light illuminates when the switch is in the ( I ) ON position. Over Temp Safety This graduated dial sets the mechanical heating cut off for the Over Temperature Limit system (OTL). The OTL helps prevents unchecked heating of the chamber in the event of an electronics failure or external heat spike. - Page 28 CONTROL PANEL Set CO Display and Controls Shows the current concentration of CO as a percentage of the incubation chamber Set CO atmosphere. The display has a range of OFF (0%) to 20% and an accuracy of 0.1%. The display shows “LO” until the CO sensor registers a concentration in the chamber greater than 0%.

Page 29: Operation
OPERATION HEORY OF PERATION Heating When powered, the incubator heats to and maintains a user-selected target setpoint in the incubation chamber. The incubator senses the chamber air temperature using a solid-state probe mounted on the chamber interior wall. When the incubator detects that the chamber temperature has dropped below the target setpoint, it pulses power to heating elements on the surface of the air-jacket insulation space and in the outer chamber door. - Page 30 OPERATION Atmosphere Set CO The incubator also controls and maintains the gas concentration of CO in the chamber atmosphere by operating an internal injection solenoid valve connected to a gas input port. The incubator monitors the CO concentration level in the chamber using an infrared sensor located in the recirculation duct.

Page 41: Data Output Capabilities
OPERATION UTPUT APABILITIES USB Outputs The incubator generates data outputs describing the chamber temperature and CO concentration percentage as a digital log line, once per minute. These outputs are transmitted through a USB port located on the back of the unit using RS232 serial protocol. Required Software Viewing and logging this output requires a terminal emulator program such as the open source (BSD license) emulator, Tera Term. -
Page 42: Condensation And The Dew Point
OPERATION ONDENSATION AND THE OINT Relative humidity inside the incubator chamber should never be allowed to exceed 95%. Exceeding this threshold will likely result in condensation, possible leaks around the incubator, and may cause corrosion damage if allowed to continue for any significant length of time. Condensation takes place whenever the humidity level in the incubator chamber reaches the dew point. -
