ABB 70EA05a-E HESG447419R1 Serial Link Module

Joystick operators are not recommended on certain DC applications above 24V DC which may involve lightly engaging the contacts (teasing) to achieve speed control, positioning, jogging, etc. Excessive arcing and deterioration of the contacts will occur Four-Position Joystick Operators The joystick operated control unit is intended for AC application only. For other use, see Application Caution on preceding page. The panel area required for the 4-position operator is equivalent to two standard pushbutton operators. Note: The latch holds the lever in the center position. The trigger latch must be released before lever can moved into any position.

Field Conversion 

— Gate The factory assembled 4-position operator is assembled with a gate arranged for four handle positions.  Handle Positions Three additional gates, supplied with every operator, allow on the job conversion to 3- or 8-position operation as illustrated below.The 8-position gate controls the four functions shown as “Up,” “Down,” “Left” and “Right.” The remaining four diagonal positions each actuate two adjacent functions (see Figure 47- 100); for example, “Left Down” actuates both “Left” and “Down.” The operator may be arranged for spring return of handle to center position, or maintained in up to eight positions (see description of maintained position operator).For maintained position (non-spring return), locate required maintained position or positions of operating lever in Table 47-223 and add appropriate Suffix Number to the Catalog Number selected from Table 47-222.

Contact Block Operation

 Contact blocks mount directly to the back of the operator. For reliable operation, the maximum number of contact blocks that should be installed behind each operator lever is 2 (4 total). Figure 47-101 identifies the circuits activated by each of the eight possible lever positions. Contact block plungers 1, 2, 3, 4 are depressed (change state) when handle is in the position indicated by arrows below.
