In these cases, which safety has failed will need to be determined before it can be replaced.
Page 86
Figure 66. Hopper with Side Access Panel Removed 4. The safety cables will need to be disconnected. These are the two connectors on the top far side of the panel; each has two cables coming out of them. Refer to Figure 67. Figure 67.
Page 87
5. Bring the connectors to the side panel so they can be accessed with the multimeter. Refer to Figure 68. Figure 68. Access to Connectors 6. Locate the numbers and the socket associated with each connector. Refer to Figure 69. Figure 69.
Page 88
Figure 71. Holding Multimeter Leads 9. While holding the leads to the connector, take the magnet removed from the door previously and align it with the sensor. Refer to Figure 72. Figure 72. Magnet Positioning 10. If the sensor is working properly, there should be continuity between these sockets. 11.
Page 89
14. If the sensor is working properly, move the leads to sockets 8 and 9. Refer to Figure 73. Figure 73. Multimeter Leads, Sockets 8 and 9 15. Align magnet with the sensor or have your assistant hold it to the sensor. Refer to Figure 74. Figure 74.
Page 90
19. Align the magnet with the sensor in the top corner of the hopper’s lid. The magnets are not coded and work for either sensor. Refer to Figure 76. Figure 76. Magnet Positioning 20. Repeat the procedure from before; if continuity is detected when magnet is present and shuts off when removed, the safety is okay.
Page 91
Saved data, such as cycle count, service phone number and service date, could be lost and would have to be re-entered. To prevent loss of control system functions, JBT recommends replacing the battery as soon as possible following a low battery warning message.
5. Be careful when removing the black wires on the overload. If possible, hold the overload itself and rock the connector back and forth to remove the black wires. Refer to Figure 80. Figure 80.
