Power up the AGV5 and the Display Module will go to the HOME screen of the AGV5 program within 1 minute. The HOME screen is shown below. The first line of the display indicates the status of the valve; with the input control current set to 4 milliamperes or less, the valve is OFF or closed. -
Page 16: Hardware Config
Press the setup key until the display shown below appears. The sensor voltage value for the minimum open position can now be entered. Recall the value read and recorded in section 3.5, step B. This value plus 50 millivolts should be used for the MINPOS value. - Page 17 4.1 Replacement of pressure transducer (27a) can be performed in the field under the direction of the distributor or Altronic personnel. The transducer (27a) is supplied in a kit (27) which includes all of the necessary parts. NOTE: When repairing or updating existing AGV5 units with S/N 1400 or lower, the obsolete pressure transducer and transducer housing as well as the PCB assembly MUST be replaced.
- Page 18 Disconnect the transducer (27a) from the electronics board (1a) and remove the board (1a) from the transducer housing assembly (19). Do not remove more wires than necessary. Using snap ring pliers, remove the snap ring (27b) holding the transducer (27a). With a small pry tool, remove the transducer (27a) from its housing.
