And/Or Rs-485 Communications; No Communication When The Host Computer Is Connected Directly Or By Modem To The Hydran 201Ti's Db-9 Connector - GE Hydran 201 i Instruction Manual

Chapter 12 • Troubleshooting
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 4.5.4.1 on page 4-18.
– 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 anterior to 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 anterior to 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 4.5.4.3 on page 4-20) is reset. This parameter must be set to
the desired value after the alarm has disappeared.

1. Ensure the H201Ti's CommChannel parameter (communication channel; Commu-
nication submenu; Section 4.5.6.1 on page 4-21) is set to H201Ti-DB9.
2. Ensure the H201Ti's BaudRate parameter (data transmission speed; Communi-
cation submenu) is identical to the one indicated in the Hydran Host software.
3. Ensure the H201Ti's H201Ti ID and PowerStat. ID parameters (identification
numbers of the H201Ti and the power station; Communication submenu) are
identical to the ones indicated in the Hydran Host software.
4. In the Hydran Host software, ensure the specified communication port is valid
(COM1, COM2).
5. Verify the RS-232 link cable.
