The VMAC Diesel Driven Air Compressor’s Helpful Control Box Features & Functions

D60 control box

D60 Control Box

The control box is essentially the brain of the VMAC diesel driven air compressor system. It tells the system what to do and makes decisions based on the programmed settings. The control box is also the communication hub for the air compressor, relaying important information to the operator on an “as needed” basis.

In this article, we’re going to talk about how the control box communicates with operators and what they can do to make the most of it.

3. Change Default System Settings

The VMAC diesel driven air compressor is automatically programmed for the most common applications, but that doesn’t necessarily mean those settings are right for your work. To help you set your air compressor for optimal performance, the control box enables you to update many settings as needed.

The settings that can be updated using the display box include:

  • System Pressure
  • Unload Delay
  • Standby Delay
  • Top-up Pressure
  • High Air Rate
  • Restart Pressure
  • And more!

You can modify the existing system settings by opening the SYSTEM READY menu and holding the BACK and NEXT buttons simultaneously for five seconds. To learn more about updating the D60 control settings, see the D60 Owner’s Manual.

Customizable System Settings Chart

Operators can customize the following D60 system parameters:

2. Receive Regular Maintenance Reminders

The D60 control box will let you know when maintenance is required and is programmed to give you 10 hours’ notice before the air compressor’s 500-hour and 1000-hour services are due. This will give you some time to order a new service kit, if required, and plan the maintenance time in your busy schedule.

Once the service work is complete, simply log the work in your display box and the system will record the past 10 service logs.

Here are the service reminders and notifications displayed by the display box:

Error CodeMessage DisplayedCause
29AIR FILTER PLUGGEDAir filter is not working or working incorrectly. May need replacement.
32BATTERY VOLTAGE TOO LOWThe battery voltage is below threshold for 5 seconds (see Section 7.7 for threshold adjustment).
46ENGINE RESTART DUE TO COLDThe engine has auto restarted due to the low internal temperature.
-500HR/6MTH SERV DUE IN xx HOURSThis warning will show up 10 hours before the 500 hour service interval.
54COMPRESSOR SERV 500HR / 6MTHThe system is due for a service. This warning will show after every 500 hours of running the compressor. Clearing the compressor service reminder is required through the Diagnostic menu.
-1000HR / 12MTH SER DUE IN xx HOURSThis warning will show up 10 hours before the 1000 hour service interval.
55COMPRESSOR SERV 1000HR/12MTHThe system is due for a service. This warning will show after every 500 hours of running the compressor. Clearing the compressor service reminder is required through the Diagnostic menu.
-ENGINE SERVICE 50 HOURSEngine servicing required.
-ENGINE SERVICE 100 HRS/ENG. OIL100 hour engine servicing required.
-ENGINE SERVICE 200 HRS/ENG. OIL200 hour engine servicing required.
58ENGINE RESTART DUE TO LOW BATTThe engine needs to restart due to low battery.

1. Receive Clear Error Messages

The diesel air compressor’s control box has been programmed to display error messages when the most common issues occur. These messages allow your system to communicate with you and, in many cases, tell you exactly what the problem is.

If you receive an error on your D60, you won’t be able to start the air compressor until the error is cleared. This mechanism helps protect the system, enabling it to last the entire life of your service truck, and more!

Diesel Air Compressor Error Codes

Error CodeMessage DisplayedCause
5COMP TEMP SENSOR FAILED – OPENTemperature sensor on the compressor is unplugged or wire to control box has been cut.
6COMP TEMP SENSOR FAILED – SHORTTemperature sensor on the compressor is shorted.
7COMP TOO COLD xx.x F/xx.x CCompressor is too cold to start. The temperature is displayed.
8COMP OVER TEMP xx.x F/xx.x CCompressor is too hot to start. The temperature is displayed.
9MANIFOLD TEMP FAILED – OPENTemperature sensor on the manifold is unplugged or wire to control box has been cut.
10MANIFOLD TEMP FAILED – SHORTTemperature sensor on the manifold is unplugged or wire to control box has been cut.
11MANIFOLD ERROR CHECK COALESCERTemperature sensor on the manifold is shorted.
12AIR PRESS SIGNAL VOLTAGE LOWLow voltage reading on the air pressure transducer.
13AIR PRESS SIGNAL VOLTAGE HIGHAir pressure is too high to start the engine.
14AIR PRESSURE xxx.x PSIIf the previous error is present the air pressure is displayed.
27UNEXPECTED ENGINE OPERATIONUnexpected engine operation can have many causes. It is likely due to RPM detected during an OFF state.
34ENGINE RPM NOT DETECTEDEngine RPM is not detected. Wire may be cut, tach sensor on bell-housing may be loose or fuel problem caused engine to stop suddenly.
35ENGINE CRANK TIME OUTThe engine did not start during the crank cycle.
