Electronic Overspeed Control

WARNING: Before selecting or using this product, it is important that

you read and follow the product warnings and instructions in the Owner’s

Manual.

WARNING: Failure or improper use of the Parker Chelsea Electronic

Overspeed Control, Power Take-Offs (P.T.O.s) or related accessories can

cause death, personal injury and property damage. Possible consequences

of failure or improper use of these products include but are not limited to the

following:

•Operators,bystandersorequipmentbeingcrushed,impactedorcaused

to fall due to the sudden, inadvertent, unintended, uncontrolled or

unexpected movement, stopping or starting of devices such as lifts,

hoists, blowers, augers or pumps which are driven by a P.T.O. This can

occur when the P.T.O. is improperly or unexpectedly engaged or

disengaged.

•Rotatingshaftinjuriesresultingfromskin,hands,clothing,hairorthelike

getting caught in the rotating shaft connected to a P.T.O. or the rotating

portion of the equipment driven by the P.T.O.

WARNING: Always remember to disengage the P.T.O. when the driven

equipment is not in operation.

WARNING: When the Parker Chelsea Electronic Overspeed

Control is set up in Auto Re-engagement Mode, the P.T.O. will

automatically engage when the engine RPM reaches the lower preset point

thus causing the driven equipment to become operable. The vehicle or

equipment operator must therefore make certain that other persons and

property are not in a position to be crushed, impacted, caused to fall or

otherwise injured when re-engagement occurs.

WARNING: Original equipment manufacturers incorporating the Parker

Chelsea Electronic Overspeed Control into their equipment must undertake a

failure mode and effect analysis (FMEA) to identify potential hazards created

by the Automatic Re-engagement Mode. They must then incorporate fail safe

designs into their equipment to protect operators, other persons and property

from injury associated with unexpected disengagement or re-engagement of

the P.T.O.

Safety Information

These instructions are for your safety and the safety of the end user. Read

them carefully until you understand them.

What It Is

The Chelsea Electronic Overspeed Control (E.O.C.) is an electronic

controller that prevents the Power Take-Off and driven equipment from being

operated at excessive speeds. This is done by automatically disengaging the

Power Take-Off whenever a pre-set overspeed R.P.M. is exceeded.

How It Works

The Chelsea Electronic Overspeed Control (E.O.C.) energizes the solenoid

valve that engages the clutch in the Power Take-Off. The control also

measures the speed of the Power Take-Off and electronically compares it to

the pre-set overspeed R.P.M. setting. As long as the operating speed is less

than the high limit, the Power Take-Off will operate in a normal manner.

If the operating speed exceeds the selected high limit, the control will

automatically de-energize the solenoid valve and the Power Take-Off clutch

will disengage. The clutch will remain disengaged until the speed has been

reduced to the pre-set low limit.

Installation Instructions

Under the Dash:

Select a convenient location where the indicator lights will be visible and

the ON-OFF button is accessible to the operator. Mark two mounting hole

locations, using the control panel mounting bracket as a template.

CAUTION: Do not drill into wires or a vital part on the opposite side of the

dashboard – check before drilling.

Then, drill two holes and temporarily mount the control to the dashboard, us-

ing the 1/4" screws, lock-washers and nuts provided.

On the Engine Housing:

Tilt cabs may require the control to be mounted on the engine housing,

with the mounting bracket and screws provided. Mark two mounting hole

locations, using the mounting bracket as a template.

CAUTION: Do not drill into wires or a vital part on the opposite side of the

engine housing – check before drilling.

Then drill two holes and temporarily mount the control and mounting bracket

to the engine housing.

NOTE: Adjustments will be required at the bottom of the control.

The Solenoid Valve

Select a convenient location, near the Power Take-Off to allow the use of

shorter hoses, but away from moving parts and the hot exhaust pipe. Mark

the mounting hole locations, using the solenoid valve mounting bracket as a

template.

CAUTION: Do not drill into wires or a vital part on the opposite side of the

mounting surface – check before drilling.

Attach the solenoid valve to the mounting bracket using the screws provided

and mount them to the vehicle.

The Pressure Switch

Install the pressure switch, the screen adapter and the three hoses, as

shown in the SK drawing for your Power Take-Off.

The Speed Pick-up

In case the speed pick-up was not installed at the factory, remove and

discard the plug in the Power Take-Off case over the input gear. Install the

speed pick-up and tighten it with a crowsfoot adapter and a torque wrench

to approximately 24-lb. ft. torque. Proceed with the electrical hook-up of the

control system, as shown in the SK drawing for your Power Take-Off.

Routing the Cables

Tilt Cabs: To permit the cab to tilt, the cables must be routed around the

cab pivot point.

Conventional Cabs: Holes in the ﬁrewall are usually provided for the

speedometer cable or wiring harnesses and the control cables can usually

be routed through them.

A Through-Hole: If an existing through-hole cannot be used, drill a 1"

diameter hole and install the split rubber grommet provided, after all the

wires have been installed.

CAUTION: Do not drill into wires or a vital part on the opposite side – check

before drilling.

Installation Instructions

Input Power-the Red Wire: Connect to a source of power that is “switched”

or hot only when the key is in the ON position, using the instant connector

provided. This unit can be wired to 12V or 24V DC supply (Mininum 5 amp).

Input Ground-the Black Wire: Good ground connections are important . . .

directly on the frame is best . . . ﬁberglass panels won’t work at all.

Wiring the Solenoid Valve

Ground-either Red wire: Attach the ring connector provided and make a

good ground connection, preferably on the truck frame.

Power-the “other” Red wire: Connect the other red wire to the green wire

with the butt connector provided. Route this green wire to the control unit and

connect it to the green wire.

Wiring the Pressure Switch

Ground: Using the black wire provided in the kit, push the bullet connector

end onto either terminal of the pressure switch. Make a good ground connec-

tion with the other end of the black wire, on the truck frame. Using the blue

wire provided in the kit, push the bullet connector onto the other terminal of

the pressure switch. Route the wire to the control unit and connect it to the

blue wire.

Wiring the Speed Pick-up

Selecting the Cable: A ten foot long cable is provided in the kit, which

should be adequate for most installations. Additional ﬁve or ten foot long

cables are available and can be connected end-to-end if necessary.

Dealing with Cable “Extra” Length: The cables are specially shielded and

must not be cut or spliced. Any extra length should be coiled up and tucked

away under the dash.

Routing & Protecting the Cables: Bundle together the speed pick-up cable,

the pressure switch wire and the solenoid wire. Route the wires away from

moving parts, hot pipes, sharp edges and up out of the way.
