The AB62 uses a Digital Multiplex Receiver (DMR-30) system manufactured by OEM to control the pro-
portionality of boom functions. There is a transmitter (DMT-30) in the upper control box that takes the
operator’s control inputs and relays them to the receiver, via data link (two wires). The Optimizer can be
plugged into the upper control box, with the use of an adapter (part #100329-005), or directly to the
DMR-30 in the lower control box on port P-8. Remove the existing plug on P-8 to access port.
The AB62 uses two groups of settings: “High Flow,” which pertains to the BOOM RISER, BOOM
EXTEND and STEER functions and the “Low Flow,” pertaining to the BOOM RAISE, JIB, TURRET
ROTATE, and CAGE LEVEL functions. CAGE ROTATE is also altered by adjusting the flow control valve,
located on the bottom of the valve block below the cage rotate valve. All settings correspond with how all
the functions in that particular group will react to the rheostat control on the upper control box. Each
adjustment will affect that whole group. For example: setting high flow, will change the threshold on boom
riser, extend and steer. It is important not to deviate very far from the listed settings. Before making any
changes, record the current settings. This will help to diagnose an existing or potential problem with a
function on the machine.
• Make all settings only in the order in which they are displayed.
• Max Out or MX pertains to the extension of the cylinders in the group.
• Low Range or LR pertains to the retraction of the cylinders in the group.

• Emergency stop switches must be pulled and ignition switches on. It is not necessary to have the
engine running when retrieving the initial settings or resetting the DMR-30.
• Plug the Optimizer in at either location and it should read “Run mode normal functions off.”
• If not, ensure that all switches are on and the Optimizer is plugged into P-8. If plugged into the
upper control box, ensure that there is a four-wire plug in P-8 port in the lower control box.
• Low Flow: Select THRESHOLD by pushing the threshold button. The preset value will appear.
• If it needs to be changed, use the + or - to raise or lower the value. Continue to MAXOUT and so
on until all low flow ranges are set, then push ENTER to save changes.
• High flow: Push ENTER, then + (readout will say ERROR): push + again, high flow will appear. Push
ENTER. The TH, MX, RU, RD, LR icons will appear and TH will be flashing.
• Push ENTER and the display will read: CHANGE; YES = + NO = ENTER.
• Push + and the preset value will be displayed. To adjust, push + to raise value or - to lower value.
• If preset value is correct or after resetting the value, push ENTER. You will be back to Run mode,
normal functions off. To reset the other functions, repeat the procedure until TH is flashing, as it
did above, then use the + or - to scroll to other functions; then continue.
IMPORTANT: After making changes, thoroughly test all functions for smoothness and proper operation.
