In the Main Unit, the following maximum values are automatically retained in the built-in flash memory
every hour.
• Maximum value of each segment temperature
• Maximum value of the sensor internal temperature
By using this function, the software tool can automatically calculate the alarm threshold values given
below based on the maximum values saved automatically in the Main Unit in the past after the start of
monitoring.
*1
• Alarm threshold value (threshold 1 exceeded or threshold 2 exceeded) of each segment temperature
• Differential alarm threshold value (threshold 1 exceeded or threshold 2 exceeded) with respect to the
sensor internal temperature of each segment
*1. The maximum values retained in the built-in flash memory can be reset either by the Max. temperature reset
Button on the Monitoring K6PM Screen of the software tool, or through communications.
This is a function for predicting and calculating the temperature that will be finally reached from the data
during each startup, with respect to the current temperature value (of each segment) and the sensor
internal temperature.
It is set for each Main Unit. This setting is common for all connected infrared thermal sensors.
If the arrival prediction is enabled, the Main Unit calculates the predicted arrival temperature. In such a
case, all individual alarms are judged not only for the alarm threshold value, but also for the arrival pre-
dicted value. When the arrival prediction is being prepared (calculation has still not been performed),
the predicted arrival temperature value becomes the current temperature value.
Make the following setting either by setting whether or not to enable "Use predicted arrival time" on the
Setting K6PM Screen of the software tool, or through communications.
0
The changed setting parameter is enabled after power is again supplied to the Main Unit, or after soft-
ware reset.
Note • The arrival prediction predicts high temperature from the rise in temperature. It does not predict low tem-
perature from the drop in temperature.
• The arrival prediction alarm is output when the predicted temperature exceeds the threshold value. Even
if the actual temperature has dropped but the predicted temperature has exceeded the threshold value,
the alarm output is likely to be retained.
This is a function for inversing the logic of transistor output 1 and 2 (selecting the transistor output
method).
Make the following setting either by setting the "Transistor output type" on the Setting K6PM Screen of
the software tool, or through communications.
The changed setting parameter is enabled after power is again supplied to the Main Unit, or after soft-
ware reset.
