13.1.23 Setup Lost

• Alarm type: Fail alarm
• Non-abbreviated description: Lost setup (configuration)
• Priority: Very high
• Parameter(s) involved: None
• Alarm cause(s): See below
The Setup Lost alarm can be triggered by three causes. Each one is identified by a
number displayed at the right of the message:
• (1) The value of at least one Hydran 201Ti's parameters is incorrect in the
memory; in other words, the parameter has been changed, but not by a user.
- Especially, verify the value of the CheckSum parameter in the Service
submenu. For details, see Section 5.5.4.1.
- Because of this error, the default values are now the ones being used;
verify carefully if the value of each parameter corresponds to your needs.
• (2) Sensor not installed.
• (4) Date before 1996.
If two or all above causes trigger the alarm, the numbers are added up. For example,
if, at the same time, a value is incorrect (1) and the date is before 1996 (4), the number 5
(1 + 4) is displayed.
Note: Each time the Setup Lost alarm is triggered, the BattAlr Delay parameter in the
Service submenu (see Section 5.5.4.3) is reset. This parameter must be set to the desired
value after the alarm has disappeared.
