DE-STA-CO VARI-PAK DC CONTROL - Manual (Page 14)

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.
VII. 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:

FIGURE 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 the indexer in run mode.
1 Output voltage provided can vary between 20 and 24 Volts DC.
