Standard Shelter
Cod. +030221471 – Rel. 2.0 – April 01, 2003
15
12 ALARMS
The alarms managed by the program are designed to protect the connected devices and provide signals if the control parameters are outside of
the range of normal values or if there are faults on the board. The alarms may derive from the alarm digital inputs, from the probes or from the
board. The effect of the alarms ranges from signal-only, to the shutting down of one or more devices, to the shutting down (Off) of the shelter.
Many alarms feature modifiable delays.
When an alarm goes off, the following actions occur:
• the buzzer on the external terminal sounds (not featured on the built-in terminal)
• the red LED under the ALARM button comes on
• the message AL flashes on the Menu screen
Pressing the Alarm button mutes the buzzer and displays the alarm screen. If there is more than one active alarm, once having entered the alarm
menu, simply use the arrow buttons to scroll the alarms. Pressing any other button exits the alarm screen, however the events remain saved and
are displayed again whenever the Alarm button is pressed.
To manually reset the alarms and delete the messages, simply enter the alarm screen and press the Alarm button again; if the cause of the alarms
is no longer present (digital inputs reset or temperature returned to normal, etc…) the screen disappears, the red LED goes off and the message
NO ACTIVE ALARMS is displayed. If the causes of one or more than one alarm are still present, only the alarms whose causes are no longer
present are reset, while the others remain displayed and the buzzer and the red LED come on again.
All the alarms require manual reset.
Therefore, to reset the alarms the operator must act directly on the terminal.
The alarms may be: Serious, Minor 1, Minor 2 (not present on the pCO1xs).
The type is selected on the terminal by the operator.
