Hydran* 201i Instruction Manual
The procedure is as follows:
1. Run the supervisory link cable into the conduit up to the H201Ci Controller, where
it will be connected later.
2. Ensure all wires are identified.
3. Connect the cable wires and shield to the H201Ti’s supervisory link (and analog
output) termination board. For wiring details, see Table D - 6 in Appendix D.
4. For the case when a local network of Hydran 201Ti has to be connected to the
host computer: connect the RS-485 to USB converter to your PC USB port and to
the Hydran 201 Ti RS-485 port on the 201Ti J4 Isolated Supervisory Link 6-Pin
Connector: this connector is wired to the termination board. For wiring details,
see Table D - 6 in Appendix D.
The H201Ti’s operation may be affected if wires are not
connected correctly. Be careful when installing and inserting
each wire. Be sure to insert all strands in the terminal; strands
that touch two terminals cause problems. Strip each wire to a
maximum of 8 mm before installing it. Do not leave trims of
metallic strands inside the H201Ti’s enclosure.
5. Connect the analog output wires to the SCADA system.
7.3.10 Installing the Alarms Cable (Optional)
If the Hydran 201Ti’s alarms are used, proceed as follows:
1. Run the alarms cable through the second conduit up to the H201Ti.
2. Connect the cable to the H201Ti’s Alarm Contacts 9-Terminal Block (item 12 in
Figure 3-5). For wiring details, see Table D - 2 in Appendix D.
3. Connect the cable to the SCADA system.
7.3.11 Installing the AC Power Supply Cable
1. The power supply cable of the Hydran 201Ti must be connected to an external
circuit-breaker and the installation must comply with the regulations applicable
for permanently connected equipment and in accordance with local wiring
regulations.
The circuit-breaker must be located in close proximity to the
equipment and must be easily accessible.
The circuit-breaker must be clearly identified with a label and
marked as the disconnecting device for the equipment.
2. Run the three-wire ac power supply cable into the second conduit up to the
Hydran 201Ti.
