5.7. Alarm state
The PIREG
®
-545 enters the Alarm state only when it detects an error. The controller monitors the mains
voltage, the heat seal band temperature, the current and voltage measurements on the heat seal band, the
calibration parameters and the monitor functions.
Here the error’s number, its description and a possible remedy are given.
