No Communication Between The Host Computer And The Network Of Hydran 201Ci Systems; Hydran M2-X And Hydran 201Ci Controller's Analog Outputs At Zero - GE Hydran M2-X Instruction Manual

Hydran* M2-X Instruction Manual
1. Ensure the CommChannel parameter (communication channel; Communica-
tion submenu; see Section 3.2.7) of all Hydran M2-X's connected to the H201Ci
Controller is set to Supervisory Link.
2. Ensure the BaudRate parameter (data transmission speed; Communication
submenu) of all Hydran M2-X's connected to the H201Ci Controller is identical
to the one indicated in the Perception software.
3. Ensure the H201Ti ID and PowerStat. ID parameters (identification numbers of
the Hydran M2-X's and the power station; Communication submenu) of all
Hydran M2-X's connected to the H201Ci Controller are identical to the ones
indicated in the Perception software.
4. In the Perception software, ensure the specified communication port is valid.
5. Verify the supervisory link cable.
6. Verify the RS-232 link cable.
7. Verify the power supply and the operation of the H201Ci Controller.
8. Ensure the modem's configuration string is correct.
8.2.3 No Communication between the Host Computer and the
Network of Hydran 201Ci Systems
1. Connect the host computer to each Hydran 201Ci Controller and perform the
tests listed in Section 8.2.2.
2. Verify all RS-485 network link cables.
3. Disconnect all RS-485 link cables and "rebuild" the network, one H201Ci
Controller at a time.
8.3 Hydran M2-X and Hydran 201Ci Controller's Analog
Outputs at Zero
1. If the H201Ci Controller's display is blank, read the alarm message on the
Hydran M2-X's display to identify the cause of the alarm. Then see Section
8.1.
2. Verify the fuses and power supply of the H201Ci Controller and the Hydran
M2-X.
3. Verify the connections of the TDM signal at both ends of the cable.
4. Verify the Hydran M2-X's analog output circuit by setting the Hydran M2-X's
AnalogMode parameter (Relays/Analog;Analog Out submenu; see Section
3.2.9.2) to Force 50% or Force 100%. Verify the result via the Perception
software or the SCADA system.
5. Verify the H201Ci Controller's analog output circuit by setting the Hydran M2-
X's TDM Mode parameter (Relays/Analog;TDM Out submenu; see Section
3.2.9.3) to Force 50% or Force 100%. Verify the result via the Perception
software or the SCADA system.
