Programming the alarm values
Note:
This function might not be available or accessible due to a configuration setting.
When the SELECT-key is pressed a few times, the values are displayed. These values are related
to the input value of the sensor:
1) low alarm: enter here 830 °C for example.
2) high alarm: enter here 1200 °C for example.
To change the alarm value, the following procedure must be executed:
1)
press PROG: the word "PROGRAM" will flash or a pass code will be requested,
2)
use
to select the digits and
to increase that value,
3)
confirm the new alarm value by pressing ENTER.
Fig. 4: Example of display information during programming low alarm value.
When data is altered but ENTER has not been pressed yet, then the alteration can still be
cancelled by waiting for 20 seconds or by pressing ENTER during three seconds: the former
value will be reinstated.
High or low alarm
When the actual sensor value is outside the allowed range, an alarm message will be
displayed indicating the type of alarm: "LO ALARM" or "HI ALARM". An alarm might first be
initiated after a certain period of time due to configuration settings.
The alarm is terminated automatically as soon as the value is within its range again.
Low-battery alarm
When the battery voltage drops, it must be replaced. At first "low-battery" will flash, but as
soon as it is displayed continuously, the battery MUST be replaced shortly after!
Only official batteries may be used, or else the guarantee will be terminated. The remaining
lifetime after the first moment of indication is generally several days up to some weeks.
