FIG. 11 – JUMPER “JR” OPERATION
Jumper "JR" in "F" position (factory setting)
connects "RTN" to "COM"
Jumper "JR" in "O" position opens the
"RTN" to "COM" circuit allowing the use of
an external disable contact. This will not
stop indexer in run mode.
E. +24 VDC SUPPLY – The +24V terminal provides a nominal 1 24 VDC @ 12 mA output for
use with an external load such as one solid-state 3-wire proximity switch.
F. Common "COM" — This terminal is referenced to all logic signals (RUN, JOG, STOP)
through the Return ("RTN") terminal. The control is factory supplied with jumper "JR" in
the "F" position which connects the "RTN" and "COM" terminals together.
Note: Control will not operate unless jumper "JR" is in the "F" position.
VIII. APPLICATION WIRING DIAGRAMS.
Example 1:
Solid-state switching devices, such as NPN transistors or proximity switches, may be used for
logic commands if they meet the following criteria:
Must be capable of switching 30 VDC, at 24 mA, with an off-state leakage current of less than
1 mA. (See fig. 12.) Warning! Do not ground or short +24V to com or return on TB3. Do not
use +24V for other than open collector sensors. (See fig. 12.)
Example 2: For optimum operation, contacts used on logic inputs should be rated for low-
level logic switching (i.e. gold contacts). (See fig 13.)
