Sensors

Low Alarm

Limit

• Blue, Red and White

temperature sensors

• HA-III+

• 4-20mA sensor

• Wireless humidity

sensor (EA-WHS)

• Wireless

temperature sensor

(EA-WTS)

The Low Alarm Limit sets the value that trips the low alarm when

exceeded.

High Alarm

Limit

• Blue, Red and White

temperature sensors

• HA-III+

• 4-20mA sensor

• Wireless humidity

sensor (EA-WHS)

• Wireless

temperature sensor

(EA-WTS)

The High Alarm Limit sets the value that trips the high alarm when

exceeded.

Alarm Delay

Time

All

This sets the time period that an alarm condition can exist before the

alarm is triggered. This is useful for helping to prevent false alarms from

occurring in situations where normal activities cause conditions to tem-

porarily exceed alarm thresholds. For example, the temperature in a

freezer may temporarily rise above the high alarm limit while frozen food

is being restocked and the freezer door is open, but the delay prevents

the alarm from going off unless the temperature fails to cool below the

alarm threshold within the alarm delay period.
