Manual or auto reset
Although there are many different defined alarm sequences the two most common are the manual reset and the auto-reset sequence.
The manual reset has two main controls an accept or acknowledge button and a reset button. On receiving an alarm the alarm is latched (stored). It is normally announced by an audible sound and a flashing display plus the operation of a TRIP output. The Trip output can be used to halt the process or plant. When the alarm is acknowledged the display changes to a steady indication to show the difference between an acknowledged and an unacknowledged alarm. If an alarm has cleared operation of the reset control will clear all non-present alarms and trip signals.
Where the trip has been used to lockout a plant or process often the reset button is replaced with a key switch so that only a key holder can operate the reset and restart the plant or process. This can be interfaced to a safety lockout system so nobody can restart the plant while maintenance personnel are still working in a dangerous area.
The auto reset works on the acknowledge control and once an alarm is acknowledged as soon as it clears it auto-resets.
