SECTION 8 – ALARMS
Alarm System Overview
The chamber 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 at start-
up and set point changes. To avoid nuisance alarms after a routine door opening, an
alarm condition must be present for 15 minutes 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 could be displayed:
Chamber temperature is higher than set-point temperature
Chamber temperature is lower than set-point temperature
Chamber humidity is higher than set-point humidity
Chamber humidity is lower than set-point humidity
Temperature sensor error
