MCH Control Handle/EDC |
|
Control Handles For |
|
Electrical Displacement Controls (EDC) |
|
BLN 95-9007-0101 |
Issued July 2017 |
DESCRIPTION |
|
The MCHXXX Control Handle is intended for use in openloop systems controlling Danfoss hydrostatic pumps with an Electrical Displacement Control (EDC).
These Control Handles may also be used with an MCE101 Proportional Transmission Controller in pressure or horsepower limiting applications.
The Control Handle is designed to provide a remote manmachine interface. In addition to proportional operation of electrically controlled hydrostatics, switches may be incorporated to operate backup, alarm, brake, and neutral interlock circuits.
FEATURES
• |
Choice of three mounting styles with or without water |
• |
Environmental hardened components designed for off- |
|
resistant case. |
|
road construction equipment. |
• |
Mechanical options include center lock, spring return, |
• Optional switches in knobs. |
|
|
friction held, and center detents. |
• Optional cam operated switches. |
|
• High torque handle actuation gives a realistic force feel. |
• |
Optional electrical cable and connectors. |
•Easy installation.
•Shock and vibration resistant.
ORDERING INFORMATION
The following tabulation is the list of current standard production Control Handle models for EDCs. Behind each circuit (as described in the Electrical Characteristics section of this bulletin) is the mounting, knob, and actuation which are available as production models. For example, for the B1039 circuit there is MCH12AB1039, MCH41AB1039, and MCH51AB1039 in production. Other combinations may be possible. Consult factory for availability.

MOUNTING, TYPE OF KNOB, HANDLE ACTUATION
A wide range of options to the basic Control Handle allows it be custom-tailored to each application. See Ordering Specification chart in Ordering Information.
MOUNTING (See Dimension Drawing)
1.BASE OR SURFACE MOUNT
Connection is via four screws to the flanges on the bottom of the metal case.
2.TOP MOUNT WITH CASE
Connection is via two screws to an enlarged mounting plate. Top mounting allows the entire handle to be removed from above the panel. The case is made of black nylon plastic.
3.TOP MOUNT WITHOUT CASE Same as 2, but without case.
4.PANEL MOUNT WITH CASE
Connection is via four screws to the top plate that holds the boot in place. The case is made of black nylon plastic.
5.PANEL MOUNT WITHOUT CASE Same as 4, but without case.
TYPE OF CONTROL KNOB (See Dimension Drawing)
1.NON-LOCKING
The non-locking handle has a standard ball knob. The friction-held handle detents with a spring-loaded ball to indicate null, while the spring-return handle has a springpreload indicating null.
2.CENTER-LOCK
The center-lock handle has a cylindrical knob and provides a positive center-lock that unlatches when the operator pulls up on the knob.
3.NON-LOCKING, AUXILIARY SWITCH
This knob is teardrop shaped, with an auxiliary momentary push button switch on top. The switch is wired through the handle shaft to the body with three wires (common, normally open and normally closed).
5.NON-LOCKING, NO KNOB
The customer provides has own customized knob.
6.THREE POSITION MAINTAINED ROCKER SWITCH IN KNOB
The cylindrical knob has a boot covering the three position switch in the knob. The switch, wired through the handle, is used for auxiliary functions.
9.THREE POSITION MOMENTARY ROCKER SWITCH IN KNOB
This is the same as 6, but the switch returns to the center position when released.
