    Hydran* 201i Installation Guide A description of each component: 1. Hydran 201Ci Controller (Hydran 201Ci-C Communications Controller or Hydran 201Ci-1 One -Channel Controller) installed on vibration-absorbing rubber pads (see Figure 3) 2. Full-bore gate or ball valve 3. Hydran 201Ti Intelligent Transmitter 4.
  • Page 11 Hydran* 201i Installation Guide readings; however, the lower operating temperatures and ease of access make this location a valid alternative choice. Figure 2: Mounting Locations of the H201Ti on a Transformer Also, note the following points: 1. The H201Ti must always be easily accessible. The distance between the valve and the ground must exceed 30cm (12in) to install and wire the H201Ti.
  • Page 12 Hydran* 201i Installation Guide The oil temperature at this location must always be below 30°C (86°F). Do not use a 90° elbow to convert a vertical installation to a horizontal installation. It is recommended to set the temperature set point (Temp SetPoint parameter in the Temperature submenu) of the H201 sensor to 45°C (113°F).

    Hydran* 201i Installation Guide 2.3 Vibration-Absorbing Rubber Pads If vibrations are present, rubber pads (which can be purchased from General Electric) are used on the back of the Hydran 201Ci Controllers; an example is shown in Figure 3 below. Figure 3: Vibration-Absorbing Rubber Pads Page 14 17996 Rev5, August 2013...
  • Page 14: General Warnings

    Hydran* 201i Installation Guide 3 GENERAL WARNINGS 1. Do not separate the Hydran 201Ti Intelligent Transmitters from their respective Hydran 201 sensor. The H201Ti is set at the factory for a specific H201 sensor. To verify whether the two components are paired correctly, consult the serial numbers indicated on the shipping box and/or the Test Certificate and Data Sheet.
  • Page 15 Hydran* 201i Installation Guide Figure 5: H201Ti's Serial Number and Protective Cap 2. Do not remove the protective plastic caps from the sensor and/or the brass adaptor’s threaded extremity until ready to install on the transformer valve. These caps protect the adaptor threads (see Figure 5 above) and the sensor membrane from debris and sharp objects.
  • Page 16 Hydran* 201i Installation Guide Figure 6: Do Not Touch the Membrane 4. Do not block or puncture the sensor’s breathing membrane. Located above the sensor’s connector (see Figure 4), this opening provides oxygen to the gas detector inside the sensor. Blocking or puncturing this membrane damages the sensor permanently, thus voiding the warranty.
  • Page 17 Hydran* 201i Installation Guide Figure 7: Do not Paint the Sensor or Clean it with any Solvent 7. Do not use a pipe wrench or chain wrench to install the sensor. Doing so may cause serious damage to the sensor, thus voiding the warranty. It is recommended to use General Electric’s Hydran 201TW tube wrench (see Figure 8 below) to correctly install the Hydran 201 sensor.

  • Page 19 Hydran* 201i Installation Guide 8. Do not install the H201Ti on the inlet side of the radiator pump (see Figure 9 below). Figure 9: Do Not Install the H201Ti on the Inlet Side of the Radiator Pump 9. Do not use galvanized fittings to install the brass adaptor and the sensor. Galvanized fittings (pipes, reducing bushings, rings, etc.) may react with the oil and produce elevated gas level readings.
  • Page 20 Hydran* 201i Installation Guide 10. Install the H201Ti horizontally; not at an angle, vertically or horizontally using an elbow (see Figure 10 below). Elbows may cause turbulence that can reduce the accuracy of gas level readings. Figure 10: Do Not Install the H201Ti on an Elbow 11.
  • Page 21: Before Installation

    Hydran* 201i Installation Guide If additional openings are made, the protection level given by the CAUTION NEMA / IP rating of the product may be compromised. 13. Do not remove the watertight cap from unused openings of the H201Ci’s enclosure. 4 BEFORE INSTALLATION 1.
  • Page 22 Hydran* 201i Installation Guide 3. It is recommended to mount the Hydran 201Ti horizontally. Ensure the bleed screw is on top (at the “12 o’clock” position); see Figure 13 below. Figure 13: Bleed Screw must be on top, at the 12 O’clock position 4.
  • Page 23 Hydran* 201i Installation Guide 6. The total distance between the H201Ti and the mounting point of the valve must not exceed six times the nominal diameter of the valve (230mm [9 in] for a 38mm [1.5in] valve). See Figure 14 below. Figure 14: Maximum Distance between the Hydran 201Ti and the Valve 7.
