    1 Mounting on the hydraulic fan 1.1 Removing the locking bolt

    Remove the marked locking bolt using an open-ended or socket spanner WAF 13 (Figure 1).

    1.2 Dismounting the gear motor cover

    Now remove the 3 marked nuts and the bolt on the side with an open-ended or socket spanner WAF 10, to take off the cover for the gear motor (Figure 2).

    1.3 Dismounting the pressure switch Disconnect the pressure switch (Figure 3) electrically from the terminals (as shown in the connection diagram, see Page 5). The pressure switch can remain mounted on the implement. If you want to remove the pressure switch, remove the rubber cap and then unscrew the pressure switch. Instead of the pressure switch, you must now put on the screw plug from the accessories kit on the implement.

    1.4 Mounting the fan speed sensor

    CAUTION! Based on the following points, distinguish which hydraulic fan is mounted on your Pneumatic Seeder: PS 200-500  HG 300 PS 800-1600  HG 450

     Now connect the fan speed sensor to the terminals as shown in the connection diagram

    (Figure 4) (connections marked on the connection diagram).

    Stripping length 10 mm!

    Connection diagram PS MX 3 #04

    PLEASE NOTE! The electric connection diagram can also be found on the inside of the previously removed cover for the gear motor.

     Switch on the control box and turn on the fan at a low speed (500 rpm).

     Now screw the fan speed (rpm) sensor into the fan housing until the lamp on the rear of

    the sensor starts flashing (Figure 5).

     The supplied Usit ring (Figure 5.1) does not need to be installed on the HG 300.

     Now screw the fan speed sensor by another 2.5 rotations into the housing and then fasten the sensor with the nuts located on the sensor (Figure 6).

     If the cable is very twisted, you can unplug the sensor and untangle the cable.

     Route the cable by fastening it to the blower fan with a cable tie. Then route it through the grommet on the cover. The cover is reattached to the implement using the three previously removed nuts and the screw (Figure 7).

    1.5 Installation of the hydraulic motor speed sensor HG 450 (PS 800) Possible as of serial number 08002-01500. The serial number can be found on the housing of the hydraulic fan (Figure 8). First, remove the Allen screw from the motor (Figure 9).

    CAUTION! Oil can escape during removal. Place a bucket or suitable container to collect the escaping oil.

    Then screw the sensor into the motor by exactly 32mm (Figure 10).

    CAUTION! Install the supplied Usit ring (Figure 10.1), between the motor and lock nut; otherwise, hydraulic oil will escape.

    1.5.1 Functional check First, switch on the hydraulic fan at medium speed (~1500 rpm). Afterwards, the LED display (Figure 11) must flash. If it does not flash, screw the speed sensor carefully further into the motor until the LED display flashes.

    CAUTION! If the speed sensor is screwed too far into the motor, the speed sensor can be damaged.

    PLEASE NOTE! The control box has to be switched on for the functional check.

    1.6 Pulse settings

    PLEASE NOTE! The number of pulses for the hydraulic fans of APV seed drills depends on the installation of sensor on the housing. If the sensor is installed on the outside (Figure 12), set 2 pulses. If the sensor is installed on the inside (Figure 13), set 5 pulses.

    2 Settings on control box 6.2 2.1 Activating the fan speed sensor To activate the fan speed sensor, the settings must be adjusted on the control box:

     In the main menu of the control box, press and hold the SET button for 3 seconds until you reach the submenu (Figure 14).

    Figure 14: Calling up the submenu

  • Page 12

     Press the arrow button until you reach the fan icon. Then switch to the fan speed (rpm) sensor using the "+" button (icon on the display marked in Figure 15).

     Confirm the setting with the OK button and then exit the submenu with the ESC button (Figure 16).
