To display individual probe temperatures
1. When the main display is showing, press the number of the probe you want to display.
The display shows the temperature.
2. Repeat step 1 for each probe temperature you want to view.
3. Press Back to return to the main display.
Displaying high and low temperatures
You can display the previous day’s high and low temperatures. The display shows the high
temperature for two seconds, followed by the low temperature for two seconds.
If the temperature is above 99.9 degrees, the temperature drops the decimal and rounds off. For
example, 103.2 would be 103; 103.5 would be 104.
To display high and low temperatures
1. When the main display is showing, press 5.
The display shows the high and low temperatures.
2. Press Back to return to the main display.
Acknowledging alarms
The alarm relay activates if an alarm condition (one that is enabled) is present for longer than the
minimum duration of one minute. The one minute minimum duration prevents alarms from
occurring when the temperature rises or drops for just a few seconds.
The exceptions to the one minute minimum are the actuator 1 jam and actuator 2 jam alarms.
Actuator jam alarms activate immediately after the PEC Plus detects an actuator jam.
When an alarm occurs, the alarm relay activates, the LED for ALARM switches on, and the alarm
message displays. If there is more than one message, after acknowledging the first alarm, the next
one displays.
For example, if you had a high temperature and a probe damage alarm, the display would show
x_al. After acknowledging the high temperature alarm, the display would show pdev. When all
alarms have been acknowledged, the display shows the temperature.
