High Alarm 2
Hi AL
This parameter is used to establish the relative temperature/static pressure
at which a high alarm condition will occur. When
Probe Readout 2 is above
the Main Set Point + High Alarm 2 , a high alarm condition will occur. This
parameter is adjusted in 0.1° increments from 0.5°F to 40.0°F (0.3°C to
22.2°C) or from 0.000’’H

Probe 2 Min (POS 6)
Probe 2 Minimum
This parameter displays the lowest value reached by Probe 2 since the
CPS-2C was powered up or since this parameter was last cleared. To reset
this value to the actual
Probe 2 Readout , press the SET/CLR button. The
Probe 2 Minimum is displayed to the nearest 0.1° from -58.0°F to 140.0°F
(-50.0°C to 60.0°C) or from -0.500’’H

Low Alarm 2
Lo AL
This parameter is used to establish the relative temperature/static pressure
at which a low alarm condition will occur. When
Probe Readout 2 is below
the Main Set Point + Low Alarm 2 , a low alarm condition will occur. This
parameter is adjusted in 0.1° increments from -40.0°F to -0.5°F (-22.2°C to
-0.3°C) or from -0.500’’H

Probe 1 Min (POS 7)
Probe 1 Minimum
This parameter displays the lowest value reached by Probe 1 since the
CPS-2C was powered up or since this parameter was last cleared. To reset
this value to the actual
Probe 1 Readout , press the SET/CLR button. The
Probe 1 Minimum is displayed to the nearest 0.1° from -58.0°F to 140.0°F

Alarm Code
A.CODE
This setting displays the alarm condition. This parameter displays 0 when
no errors have been detected. This indicates that the controller is operating
properly. The alarm LED (
) on the faceplate will be lit up if an alarm
code is actually displayed. The alarm code refers to the following table.
