DUO-TOUCH
When switching inductive ac loads, it is good practice to protect the Safety Module
outputs by installing appropriately-sized arc suppressors. However, if arc suppressors
are used, they must be installed across the load being switched (e. g., across the coils
of external safety relays), and never across the Safety Module’s output contacts (see
WARNING on page 7).
To perform the initial checkout, it is necessary to view the red Fault LED and the four
green status indicators: Power, Input 1, Input 2 and Output. Proceed with caution
around open wiring.
1. Verify that the two actuating devices are properly connected to the DUO-TOUCH
2. Apply power to the Safety Module and to the actuating devices, if applicable.
3. Verify that only the Power indicator is ON. If any of the other Safety Module
4. Activate both hand controls simultaneously (within 0.5 seconds), and hold them
5. Again, activate the two hand controls simultaneously, and hold them engaged.
6. Activate only one hand control and hold it engaged. Input 1 (Input 2) indicator
7. Remove power from the Safety Module and disconnect the monitor contact
If the DUO-TOUCH SG Safety Module passes all of these tests, reconnect the output
wires at terminals 13/14, 23/24, 33/34 and 43/44, and the monitor contact feedback
loop at terminals Y1 and Y2. Do not attempt to use the DUO-TOUCH SG Two-Hand
Control Safety Module until all of the tests are passed.

controls simultaneously. Output indicator should go OFF.
Input 1, Input 2, and Output indicators should come ON. Release one hand
control, while holding the other engaged. One of the indicators should remain ON.
The Output indicator should go OFF. Re-activate the hand control which was just
released. The Output indicator should remain OFF. Release both hand controls.
Input 1 and Input 2 indicators should then be OFF.

Before performing the initial checkout
procedure, make certain all power is
disconnected from the machine to be
controlled. Temporarily disconnect the
wires connected to the outputs of the DUO-
TOUCH SG Safety Module at terminals 13/14,
23/24, 33/34, 43/44, Y32, and Y33.
If all of the described checks cannot be
verified, the two-hand control system
must not be used until the problem
has been corrected. Injury or death to
personnel may result from attempts to
use the machine under such conditions.
