General Information

Optional Equipment Compatibility

While VMAC strives to design systems compatible with optional OEM equipment (such as running boards), it is impractical to develop systems that accommodate every OEM and aftermarket option or add-on. Whenever possible, VMAC endeavors to advise of compatibility issues in the “Additional Application Information” section of the manual. Even when specific optional equipment is determined by VMAC to be incompatible, it does not preclude the vehicle upfitter or end user from modifying the optional equipment to make it compatible with the installed VMAC system. VMAC does not warrant or accept responsibility or liability for the fitment, function, or safety of any products modified in any way not expressly outlined in the installation manual.

Before Starting

Read this manual prior to beginning the installation to ensure familiarity with the components and how they will fit on the vehicle. Identify any variations from the application list such as vehicle model, engines, or optional equipment (e.g., dual alternator, active steering assist, etc.).
Open the package, unpack the components and identify them using the Illustrated Parts List (IPL) included in the Fastener Pack.

Hose Information

Depending on other installed equipment, it might be necessary to move the air/oil separation tank from its intended location. The hoses used in VMAC compressor systems have a specific inner liner that is compatible with VMAC compressor oil.
Use of hoses other than those supplied or recommended by VMAC may cause compressor damage and may void your warranty. Please contact VMAC for replacement hoses and further information.

Ordering Parts

To order parts, contact a VMAC dealer. The dealer will ask for the VMAC serial number, part number, description and quantity. Locate the nearest dealer online at www.vmacair.com/dealer-locator or call 1-877-912-6605.

Electrical System Best Practices

To confirm a good ground, use an ohm meter to measure the resistance between the ground point and the negative battery terminal. Resistance should be less than 1 Ω.
Route all wires to ensure they will not contact hot, sharp or moving parts (including the park brake mechanism, steering column, and pedals).
Before drilling any holes ensure there are no OEM wires, hoses, or components that may be damaged.
Do not use a test light to probe for power on vehicle circuits, the increased current draw of the test light may damage components.
VMAC recommends using only sealed crimp connectors for all electrical connections.
To ensure a durable connection, use only good quality crimping tools.
Apply loom to all wiring:
- Use high temperature loom in areas where high temperatures may be expected.
- Use spiral loom in areas with high vibration.

In-line Butt Splice Connections

Cut the wire approximately 2 in from the connector.
Strip approximately 3/8 in from the end of both sides of the cut wire, as well as from the end of the wire being spliced in-line.
Twist the wire to be spliced in-line, together with the “live” side of the wire (not the wire attached to the connector).
Slide the butt connector onto the twisted wires and crimp it.
Insert the “connector side” of the wire into butt connector and crimp it.
Lightly tug the wires to ensure they are properly crimped.
Using a heat gun, carefully apply heat to the butt connectors to seal the connection.

Tying into OEM connectors

Some OEM connectors may have locking tabs that must be disengaged prior to inserting a crimped connector.

Overview

Operation

The Crane Remote Interface kit provides external connections to allow control of the MF/GMF’s remote start/stop, PTO, generator, and compressor enable/disable via a third party remote control (remote not included).

Figure 2 — Crane Remote Interface

The Crane Remote Interface is designed to convert latching, or momentary switched 12 V signals into the low-side switching required by the MF/GMF control system (Figure 2).

The MF/GMF has 8 inputs, ×4 latched and ×4 momentary. Refer to the documentation provided by the remote control manufacturer to determine the output logic and select the appropriate Crane Remote Interface inputs.

The Crane Remote Interface operates in parallel with the rocker switch panel supplied with the MF/GMF. If either the rocker switch, or an input on the Crane Remote Interface is turned on then that function will be enabled. The rocker switch does not have to be enabled for the function to be enabled/disabled remotely.

Maintenance and Repair Safety

| Prior to performing any service, ensure the vehicle is parked on level ground and that the transmission is in “PARK” with the parking brake applied and the wheels chocked (if applicable).
---|---
| It is impossible to warn of all the possible hazards that may result from operating, servicing, or repairing this system.

Wear all appropriate Personal Protective Equipment and follow all industry standard safety practices.

| Confirm that the system is depressurized and has cooled prior to performing any service work.
| Never use flammable solvents to clean any components. If a flammable solvent has been used, rinse the component thoroughly with water and dry it before reinstalling it to prevent the possibility of explosion.
| Use only genuine VMAC parts to maintain the system.

Genuine VMAC parts are designed to work with the high pressure and heat generated by the compressor. Substituting genuine VMAC parts may void the warranty and could cause equipment damage, injury, or death.

| This information is intended for people with mechanical trade certification who have the tools and equipment to properly and safely perform the service or repair. Do not attempt to service or repair this system without the appropriate mechanical training, knowledge and experience.

Follow all safety precautions and industry standard “best practices”.

Safety Check List

Open the ball valve or connect an air tool to the system to ensure all of the stored air is released.
Gently pull up on the ring, on the pressure relief valve (located inside the service panel), to confirm the system is depressurized.
Disconnect the negative battery terminal.

Do not use the pressure relief valve as a means of depressurizing the compressor system. Doing so will prematurely wear the internal spring or the seat, preventing the valve from maintaining normal system pressure.

Installation

Pre-installation test

Test run the MF/GMF prior to installing the crane remote to confirm proper functionality of all components.

Refer to the Completing The Installation section of the installation manual to find Testing The System instructions.

Kubota | CAT Powered

Ensure the key switch is in the OFF position.
Locate the 5-Pin connector and blunt cut yellow remote start wire at the base of the MF near the air discharge. (Figure 3, Figure 4).

**Figure 3 — Remote start 5-pin connector/remote start wire location (current systems)

Figure 4 — Remote start 5-pin connector/remote start wire location
** (older Kubota powered units only).

Honda Powered

Remove the discharge side panel (Figure 5).

Figure 5 — Remove discharge side panel to access wire harnesses

Locate the wire harness with a 5-Pin connector and the yellow blunt cut remote start wire coiled inside the GMF (behind the discharge side panel, under the control module) (Figure 6).
Previously installed GMF: the harness may be routed through the wire harness port next to the air discharge fitting, or through the deck surface beneath the GMF.

Figure 6 — Wire harness location

Connect the Crane Remote Interface in line with the 5-pin connectors between the MF/GMF and its display box.
Using a sealed butt connector, connect the yellow remote start wire from the MF/GMF to the long yellow wire from the Crane Remote Interface.
Connect the chassis ground wire to a ground shared with the Crane Controller.
Test the Remote Crane Interface to confirm normal operation prior to making connections to the third part rocker switches, crane controller etc.
Ensure all of the rocker switches on the MF/GMF display panel are in the OFF position.
Turn the MF/GMF key switch to the ON position without starting unit.
Apply 12 V to either the momentary or latched Compressor, PTO, or Generator input. The corresponding MF/GMF rocker switch LED should light up.
If the MF/GMF rocker switch does not light up, review the Crane Remote Controller (Figure 1 on page 9) and the system specific electrical schematic to verify proper wiring.
Scan or click the QR code.

Use only one input wire for each function. (i.e., do not connect both latched and momentary engine start/stop wires).

Connect the remote outputs of the crane controller to the Crane Remote Interface wires.
- Latched inputs accept 12 V signals and will enable a particular function while receiving 12 V. As soon as the 12 V signal is removed the function will disable.
- Momentary inputs accept 12 V signals and will enable the specific function when 12 V is momentarily applied and removed. The function will remain enabled until 12 V is applied to, and removed from that wire again.
Unused input wires on the A500029 must be appropriately terminated to prevent erroneous activation (i.e. blunt cut and protected with heat shrink).

Final Testing

Ensure all of the rocker switches on the MF/GMF display panel are in the OFF position.
Turn the MF/GMF key switch to the ON position without starting the unit.
Activate the switches on the third party equipment, crane controller, etc. The corresponding rocker switch LED on the MF/GMF system display panel should light up.
