Time In Service; Power Cycle Track - Honeywell ST700 User Manual

Time in Service

This is the amount of time the device is in operation and is displayed in minutes.
Service Life
This is the average service life of the device under ideal conditions is 27.3 years. But, the
service life varies depending on external factors such as temperature. Service life indicates
the amount of service life that has been used by the device. Service Life is dependent on the
temperature of the device only. The Service life is calculated in percentage.
Stress monitor
This is the amount of time the device has been used under stressful conditions. For
example, say temperature of the device. The stress monitor is based on the temperature of
the device. The Stress monitor is calculated in percentage.
Stress monitor = Amount of time the device was under stressful conditions

Power Cycle Track

The power cycle track gives diagnostics related to the power up information of the device.
The Power Cycles is the number of power ups experienced by the device after leaving
factory. The Last Power Up Cycle time is the date and time of the last power up.
Operating Voltage Track
The statistics data for the supply voltage are tracked in the Operating voltage track. Supply
Voltage is the current value of the voltage at the device input terminals. The status of the
supply voltage whether it is normal or below operating value is indicated in the Status of
Current Voltage parameter. Minimum Voltage is the value of the least voltage
experienced by the device at the input terminals in its life time. Last Minimum Voltage
Time is the date and time of the last minimum voltage experienced by the device. The
Minimum Voltage can be reset by using the Reset Minimum Voltage parameter.
