Hold/Run Key
Pressing the Hold/Run key on the controller
silences the audible alarmand extinguishes the
humidity alarm indicator and the L4 indicator
on the controller. A4HI/A4LO flashes on the
lower display until the cabinet humidity
returns to the system setpoint.
Note
The humidity controller’s high and low
limits are factory-set at 100% and 0%.
Therefore, the system will go into the alarm state
when the humidity exceeds these percentages by
one percent. When operating the incubator near these high or low
humidity levels, frequent alarms may occur. This will require that the
controller’s high or low limit be reset to three or four percent over the high
limit or three or four percent under the low limit. Refer to the Watlow
User’s guide provided. Refer also to the factory configuration records
located at the end of Section 4 of this manual.
