The remote connection is used when you wish to index the unit other than by the START switch on the front
panel. This frees the operator from having to touch the control to start indexing. For example, using our optional
remote quill switch (Haas P/N RQS) for Bridgeport milling machines, every time the quill handle is retracted it
touches a micro switch on the clamp and the indexing head will rotate automatically. This eliminates the need
to remove your hand from the quill, increasing production dramatically. Using a magnetic base, an aluminum
bracket, and a micro-switch you can get the unit to index almost anywhere you wish. Use the switch to index
the unit when you are milling. Every time the table comes back to a certain position, a simple bolt on the table
can close the switch, indexing the unit.
Refer to Figure 2. By simply connecting pins 3 and 4 together, the control will index. Be careful that you do not
apply power to these lines (3 and 4 only). You do not need to hook up the feedback pins 1 and 2 unless you
want the control to start another mechanism such as an automatic drilling head. The feedback pins (1 and 2)
do not need to be connected for the control to operate.
Color-coded remote interface cables are available, as an option, to help the users understand the M-function
hookup. They are coded as follows:
1 = red 3 = black
2 = green 4 = white

NOTE: All Haas controls come standard with 1 CNC interface cable. Additional CNC
interface cables can be ordered (Haas P/N CNC).
CNC machines have Miscellaneous functions called M functions. These control external switches (relays) that
turn things on or off (i.e., spindle, coolant, etc.). Most CNC controls provide some degree of access to the M
functions, with most late model machines providing several spare relays just for this purpose. The HAAS
remote cycle start line is hooked into the normally open contacts of a spare M function relay. Our remote
feedback lines are then connected to the M function finished line (MFIN), which is an input to the CNC control,
to cancel the M function and proceed to the next block of information.
On late model CNC machines, interfacing the unit is relatively simple, if you know where to make the connec-
tions. Your machinery dealer is the best source for this information.
