Alarms (Smartdry™) - ECD SmartDRY SD Series Setup And Operation Manual

9.1.2 ALARMS (SMARTDRY™)
An Alarm can be set on both the RH and Temperature values in the SmartDRY™ mode. These alarms are inde-
pendent of the alarms that can be set in the optional SmartBAKE™ mode. Both the RH and Temperature
alarms are an "over limit" type, meaning, the alarm will sound when the measured value rises above the set
Alarm value. A delay time can also be set for both the RH and Temperature alarms. This means the alarm will
NOT sound until the alarm condition has been met for at least the programmed delay time. The alarm limits
have been preprogrammed however are not enabled. Once the SmartDRY™ cabinet has stabilized at set point,
the alarms can be enabled. This is the only alarm required by J-STD 033 to monitor the RH level. You may also
want to explore the other Alarms: SmartDRY™ Temperature, SmartBAKE™ RH, and SmartBAKE™ Temperature,
enabling them as you wish.
THE DELAY TIMER FOR THE RH ALARM WILL COUNT DOWN, NOT RESET, WHEN THE MEASURED
VALUE FALLS BELOW THE ALARM VALUE AND BEFORE THE DELAY TIME IS REACHED. THIS COUNT
DOWN IS IN1/10TH TIME, IN ACCORDANCE WITH AND AS DESCRIBED IN J-STD-033, "SHORT DU-
RATION EXPOSURE" FOR THE WORST THE CASE MSL COMPONENT "FLOOR LIFE CLOCK RESET."
THUS, IF THE INTERIOR RH VALUE OF THE CABINET RISES ABOVE THE ALARM VALUE (SAY, BE-
CAUSE THE DOOR IS OPEN) FOR 25 SECONDS, ONCE THE DOOR IS CLOSED AND THE RH RETURNS
TO BELOW THE ALARM VALUE, THE DELAY TIMER WILL TAKE 250 SECONDS TO COUNT BACK TO
0.
THE DELAY TIMER FOR THE TEMPERATURE ALARM WILL COUNT DOWN AT A 1 TO 1 RATE WHEN
THE MEASURED VALUE FALLS BELOW THE ALARM VALUE AND BEFORE THE DELAY TIME IS
REACHED.
