Buhler 2360, 2335, 2425, 2290, 2375 manual General Information

SECTION 1 - GENERAL INFORMATION

Some monitors require a true ground speed signal from a radar unit to be fed into them for proper operation.

Buhler Versatile 4WD tractors equipped with a Tractor Performance Monitor (TPM) option can provide this signal to the monitor by tapping into the existing wire harness on the tractor.

To tap into the existing signal wire on the tractor, use the following procedure:

a. Remove the cover from the rear of the TPM module on the right-hand console. The cover, 1, is held in position with velcro.

b.Pull out wire harness, 1, that is tucked into the rear of the TPM.

c.The TPM is connected to the main cab wire harness with a green 8-pin connector. Locate the gray wire marked “CM-90” that is plugged into the connector.

Wire “CM-90” is a processed 5-volt signal that supplies the TPM with a 58.9 Hz/mph output from the Electronic Instrument Control System monitor

d.Using a pigtail-type splice connector, tie into the “CM-90” wire with the wire leading into the implement monitor.

The monitor will now receive a signal from the radar unit at the front of the tractor.

e.Route the signal wire along the right-hand console and out to the implement monitor.

f.Reinstall the TPM wire harness and connect back into place and install the TPM backplate.
