POWER TAKE-OFFELEVATED IDLE CONTROL — DIESEL ONLY

Page 274 APPENDIX

AUXILIARY IDLE CONTROL KITSThe Auxiliary Powertrain Control Module (APCM),available since 1995-½ to elevate 7.3L diesel engineidle, is replaced by two separate idle control kitsdescribed below. The carryover APCM is no longerproduced, but all three modules will operate with 7.3Lturbo diesel engines from 1995-½ through 2000 modelyears. Each kit includes an Auxiliary PowertrainControl Module (APCM), wiring harness, mountingbracket with hardwear, operator’s card and instructionbook. Kits are shipped with the vehicle for customerinstallation. The APCM wire harness that connectsunder the instrument panel is not intended to belengthened. The modules are splash-resistant but notwater-proof.

RPM then the APCMwill default to one of its limits. Example: Programmingwhile engine is at W.O.T. of near 3400 rpm will result inthe APCM recording a 2500 rpm setting.

This module is pre-programmed for Automatic ChargeProtection. This means that on engine start-up, theCharge Protect light will flash. If all vehicle enablingconditions* are met, Charge Protection mode will beentered automatically.

1. To maintain battery voltage: (This is Charge Protectionmode)

� Press [CHARGE PROTECT] key

— Charge Protect light flashes

— Engine speed increases based on voltagerequirement

— Battery voltage is displayed on the screen

2. To get a high idle speed: (This is RPM Control mode)

� Press [RPM CONTROL] key

— RPM Control light flashes

— Engine idle speed is elevated to the presetvalue

— Current engine speed (RPM) is displayed onthe screen

To go back to normal idle:

You can do ANY ONE of the following:

� Press [CHARGE PROTECT] key when in ChargeProtection mode

� Press [FORD] key

� Press brake or clutch pedal, take out of park, orrelease parking brake

� Press [POWER] key (module is turned off)

Vehicle Enabling Conditions* - All must be met for any highidle mode.

1. Set parking brake

2. Gear selector in PARK for automatic transmissions

3. Foot off clutch pedal for manual transmissions

4. Foot off service brake

5. Foot off accelerator pedal

6. Brake lights are connected and functional

Programming the Module

1. Reset Default Programming

a. Press the [CHARGE PROTECT], [RPM CONTROL],and [FORD] keys simultaneously for 5 seconds.

b. The default values are restored: Automatic ChargeProtection is ON and RPM preset is 1300 RPM.

2. Program new RPM Preset Value

a. With the vehicle stationary (parking brake on andvehicle in park), increase the idle with the acceleratorpedal to the desired speed.

b. Press [RPM CONTROL] and [FORD] keys for 3seconds to save. RPM Control light turns off when it isprogrammed successfully.

c. The preset speed can range from 1100 RPM to 2500RPM.

3. Program Automatic Charge Protection

a. Press [CHARGE PROTECT] and [FORD] keys for 3seconds to program off Automatic Charge Protection.

b. Repeat this step to turn back on.

To maintain battery voltage: (This is Charge Protection)

� Press [CHARGE PROTECT] key or RemoteCharge Protect button.

To get a high idle speed: (This is RPM Control)

� Press [RPM CONTROL] key.

— Use [Arrow] keys to select other RPM memorypresets.

� Press [FORD] key or Remote Ford button.

— Use [Arrow] keys to adjust engine speedmanually (up/down fast/slow).

Note: If the PTO Control output turns on when RPMControl mode is activated, then PTO Control andRPM Control are programmed to be linked.

To adjust engine idle remotely: (This is Custom RPMControl)

� If Custom RPM is programmed, the [RPMControl] light will be on, also the display will showthe speed associated with the input voltage. If“OFF” is displayed, the input boltage is out ofrange.

� Adjust input voltage to the desired engine speed.

� Press [FORD] key or Remote Ford button toactivate Custom RPM Control. Use remote pot toadjust engine speed manually.

To turn on a Power Take-Off: (This is PTO Control)

� Press [PTO CONTROL] key to turn on PTOoutput, press again to turn off.

If programmed for Automatic RPM Control or AutomaticCharge Protection, the function will be active whenever thevehicle enabling conditions* are met.

To Go Back to Nomal Idle (and exit RPM Control orCharge Protection mode)

You can do ANY ONE of the following:

� Press key for the function in use (key will belighted and blinking)

� Press brake or clutch pedal, take out of PARK, orreleasing parking brake

� Press [FORD] key or Remote Ford button

� Press [POWER] key

Vehicle Enabling Conditions* - All must be met for any highidle mode.

1. Set parking brake

2. Foot off clutch pedal for manual transmissions

3. Gear in PARK for automatic transmissions

4. Foot off service brake

5. Foot off accelerator pedal

6. Brake lights are connected and functional

Main Programming Mode

Press and hold [RPM Control], [CHARGE PROTECT],and [FORD] keys for 3 seconds.

� [FORD] key saves entry and moves to the nextmenu.

� Any [Arrow] key will toggle between options ineach menu.

� To Exit, move through all 5 menus or repeat entryprocess.move through all 5 menus or repeatentry process.

RPM Preset Programming Mode

Press and hold [RPM Control] and [FORD] keys for 3seconds.

� [Arrow] keys adjust Memory Preset #1

� Press [FORD] key to save and go to next menu.� For another memory preset, press [FORD] and

[Arrow] key simultaneously

� To Exit, press [RPM Control] and [FORD] keyssimultaneously for 3 seconds

Remote Switch Installation

For Remote RPM Control & Remote Charge Protection,use Momentary Contact (push button) switches withNormally Open contacts. The switches selected should beable to handle a 5VDC, 20mA nominal signal. Qualityindustrial switches with gold contacts are recommendedfor contact durability due to the low current.

For Remote Charge Protection:

Connect switch to red VREF output wire and orange CHGinput wire. The Remote Charge Protection switch willfunction the same as the [CHARGE PROTECT] key on themodule.

For Remote RPM Control:

Connect switch to red VREF output and gray RPM MCinput. The Remote Ford switch will function the same asthe [FORD] key on the module for RPM Control activation.

Custom Switch Installation

Custom Remote RPM Control requires a potentiometertype input. The potentiometer or other type of resistornetwork, is used to adjust the engine speed by providing avoltage between 0.5V and 4.5V to the module. For remoteactivation, it is recommended that a Remote FORD switchis installed as described above to activate and deactivateCustom RPM Control.

Quality UL recognized industrial switches with goldcontacts are recommended for contact durability due tothe low current.

Programming is required to use the custom switch.

For information on what engine speed (RPM) valuecorresponds to what custom input voltage (V), refer toSection 9.

For Remote Custom RPM Control:

Connect potentiometer to red VREF output, black SIGRTN, pink CUSTOM input. The Custom Input Voltageshould sweep between 0 and 5V. A 5–10k� potentiometeris recommended.

(normal idle)

V=(RPM - 1037.5) / 325 RPM = 325 x V + 1037.5

PTO Control Installation

For 4R100 PTO usage:

Connect the yellow PTO output to the 12V PTO solenoidAND PTO input circuit to the PCM. Refer to Ford BodyBuilders Manual for latest Power Take-Off installationinformation.

For other electrical loads:

Connect the yellow PTO output to an external 12Velectrical load.

Refer to Section 9 for specifications for the PTO driveroutput source.
