Upfitter Vehicle Controls
The following steps are only applicable to vehicles equipped with third party
vehicle control systems (such those included with hydraulic cranes).
On vehicles with additional control systems (such as crane remotes), the DTM70-H
can be activated/deactivated remotely much like a standard PTO using these
controls.
In order to activate the PTO and VMAC Control Box with third party vehicle
controls (e.g. crane remote):
☐
Connect the purple wire from the VMAC Control Box to the PTO activation
circuit on the third party vehicle controls. The VMAC Control Box requires a
+12 V DC latching input.
This section is intended as a general guideline. Refer to the third
party vehicle control manufacturer’s documentation for specific
installation instructions.
All third party vehicle control systems intended to activate the PTO
system must do so via the VMAC Control Box. Refer to the electrical
schematic on page 36.
It is the responsibility of the installer or upfitter to ensure that third
party vehicle control systems are not able to affect engine speed
while the PTO system is in use.
Any change to engine speed while the PTO system is activated could
cause component damage or unexpected hydraulic circuit function
(e.g. unpredictable crane control) which could result in injury or
death.
