Blade Pitch Control

There are two modes of operation of the blade pitch system that can be set by the Pitch Mode Switch (Figure 20):

„„Smart Pitch™ „„Manual

The trowel blades can be pitched for various finishing operations with the two rocker switches located on the left control panel next to the left joystick control (Figure 20).

NOTICE

Moving the switches forward increases the pitch while moving them backward decreases the pitch.

NOTICE

Momentarily depressing the Twin Pitch Switch will re- synchronize the pitch.

MANUAL Mode (Pitch Mode Light is Off)

1.When the Twin Pitch Switch is pressed (up or down), the pitch on both rotors will be changed simultaneously but non-synchronously.

2.When the Left Pitch Switch is pressed the pitch on the left rotor will be changed, while the pitch on the right rotor remains constant.

Smart Pitch™ Mode

When the Pitch Mode Switch is in the Smart Pitch™ position (indicator light on), the twin-pitch and left-pitch switches operate as follows:

1.When the Twin Pitch Switch (3-position, center off) is pressed (up or down), the right and left hand rotor pitch are changed and then the left hand rotor pitch is synchronized to the right hand as follows:

a.The Twin Pitch Switch (up or down) causes the RH Pitch (up or down) Coil and LH Pitch (up or down) Coil and Pitch Dump Valve Coil to be actuated changing the pitch of the blades.

b.When the operator achieves the desired pitch on the right hand blades and releases the Twin Pitch Switch, the LH Pitch (up or down) coil and Pitch Dump Valve Coil are actuated until the calibrated LH Pitch Position signal matches calibrated RH Pitch Position signal (.010” by Default). During this time the Pitch Mode Light will flash (.1 s on, .1 s off).

2.When the Left Pitch Switch (3-position, center off) is pressed the pitch on the left rotor will be changed, while the pitch on the right rotor remains constant.The Pitch Mode Light will turn off, to indicate pitch function is in

NOTICE

IMPORTANT! To get blades absolutely flat for using float pans, pitch them as follows:

Press and hold down both pitch switches until mode light blinks before installing float pans.

PANNING Mode

When both the Twin Pitch Switch and Left Pitch Switch are pressed in the down position and held for preset period (5s by default), the machine will enter Panning Mode.

1.The RH Pitch DN Coil and LH Pitch DN Coil will be activated pulling the yokes upward against Retracted Cylinder Stop, deactivating the pitch system, and allowing the blades to float for panning.

2.The Pitch Mode Light will flash (.9 s on .1 s off) when in this mode.

3.Machine remains in this mode until either the Twin Pitch Switch or Left Pitch Switch is activated in the upward direction.
