SAFETY PRECAUTIONS
Safety is everybody’s business and is based on your use of good common sense. All situations or
circumstances cannot always be predicted and covered by established rules. Therefore, use your past
experience, watch out for safety hazards and be cautious. Some general safety precautions are given
below:
Failure to observe these notices will result in injury to or death of personnel.
Keep fingers and clothing away from rotating fan, drive coupling/belting, etc.
Disconnect the compressor unit from its power source, lockout and tagout before working on the
unit –this machine is automatically controlled and may start at any time.
Do not loosen or remove the enclosure or belt covers, or break any connections, etc., in the
compressor air system until the unit is shut down and the air pressure has been relieved.
Electrical shock can and may be fatal.
Perform all wiring in accordance with the National Electrical Code (NFPA-70) and any applicable
local electrical codes. Wiring and electrical service must be performed only by qualified
electricians.
Open main disconnect switch, lockout and tagout and check for voltage before working on the
control.
Failure to observe these notices could result in damage to equipment.
Stop the unit if any repairs or adjustments on or around the compressor are required.
Do not use the air discharge from this unit for breathing –not suitable for human consumption.
An Excess Flow Valve should be on all compressed air supply hoses exceeding 1/2 inch
inside diameter (OSHA Regulation, Section 1926.302).
Do not exceed the rated maximum pressure values shown on the nameplate.
Do not operate unit if safety devices are not operating properly. Check periodically. Never
bypass safety devices.

SECTION 2
GENERAL
The Gardner Denver Governor™ controller is an advanced electronic control system designed to provide
optimal operation of your Gardner Denver compressor. This manual describes the controller
specifications and operation on Gardner Denver rotary screw compressors.
2.1 Components and Layout
The Governor™control system is made up of several different components, described briefly in this
section.
2.1.1 Display
The display is the primary component that the user interacts with. On the front of the display, there is a
color screen with touchscreen interface. The Start and Stop touch buttons are located directly below the
screen. The display houses the processor and memory for the system and interfaces with the other
components through communications ports.
Figure 1: Home Screen Display
13-17-621 Page 8
The display is shown above in Figure 1 with the Home screen visible. Note that the Start and Stop
buttons as shown in the image are active areas of the touchscreen rather than physical buttons.
2.1.2 IO Module
The IO module is mounted inside the compressor cabinet and connects to the display as well as all of the
digital and analog inputs and outputs on the system. These values are monitored and controlled by the
display to operate the compressor. The IO module also contains RS485 communications ports for
customer connection and sequencing.
Figure 2: IO Module
The IO module is shown in Figure 2 above. Note that depending on the type of compressor you have,
your IO module may have more or less inputs and outputs present on it, indicated by the amount and size
of connectors on the board.
13-17-621 Page 9
2.1.3 Cellular Module
The Governor™ controller features a cellular module that is connected to the display by USB. This
connects into the iConn by Gardner Denver™ platform to provide machine health monitoring and
analysis.
Figure 3: Cellular Module
The cellular module is shown in Figure 3 above. It is mounted in the control cabinet and connected to an
antenna mounted on the top of the compressor package.
2.2 Features and Method of Control
The Governor™ controller is responsible for safe operation of the compressor package and optimal
operation under the customer’s parameters. The Governor™ controller utilizes Gardner Denver’s heritage
of compressor package design and operation to intelligently determine when the machine is operating
normally and when it needs attention. System inputs, such as pressure and temperature, are looked at
individually and collectively to check for a variety of different conditions.
When running the machine, the controller ensures that the customer’s pressure requirements are
maintained. After configuring and enabling the controller, all operation is automatic. The controller can be
set up to start / stop on a schedule and use two different pressure bands to more efficiently meet system
demand. Programmable inputs and outputs are available to interface to an array of external equipment.
Modbus and remote interfaces are provided to monitor the machine.

SECTION 3
QUICK START
This section provides the basic information on the controller so that the user can understand how to
interact with and operate the machine. It focuses only on the common elements of the user interface and
the settings and actions that are required to get the compressor running and producing air.
3.1 Common User Interface Elements
The user interface has common elements that are shared across all screens in the system.
Understanding these elements will help improve interaction with the controller.
3.1.1 Common Navigation and Status Elements
Figure 4: Common Screen Elements
The common status and navigation elements are shown in Figure 4 above and described below.
1. The Menu bar expands when pressed and provides a cascading navigation for all screens on the
system.
