ALARMS
Alarm System Overview
The chamber light intensity and control system is equipped with an alarm system that
constantly monitors temperature, and humidity (on humidified models) to ensure the
user is notified if the cabinet goes into an alarm condition. Notification occurs via an
alarm pop-up window and a buzzer. Each alarm condition has been factory
programmed to minimize nuisance alarms while maximizing warning time. There is a 2
hour time delay after start-up and setpoint changes. To avoid nuisance alarms after a
routine door opening, an alarm condition must be present for 15 minutes (45 minutes for
humidity) before the operator is alerted. If the optional remote alarm contacts are
present, in an alarm condition, the dry contacts will change state.
The following alarm messages may be displayed:
•
Chamber temperature is higher than setpoint temperature

Chamber temperature is lower than setpoint temperature
