DUO-TOUCH® SG Two-Hand Control Modules

Initial Checkout Procedure

CAUTION: Disconnect Power Prior to Checkout
Before performing the initial checkout procedure, make certain all power is disconnected from the
machine to be controlled.
Dangerous voltages may be present along the Safety Module wiring barriers whenever power to the ma-
chine control elements is ON. Exercise extreme caution whenever machine control power is or may
be present. Always disconnect power to the machine control elements before opening the enclo-
sure housing of the Safety Module.
Temporarily disconnect the wires connected to the outputs of the DUO-TOUCH SG Safety Module at terminals 13/14, 23/24, 31/32, Y32,
and Y33.
WARNING: Do Not Use System Until Checkouts Are Verified
If all of the described checks cannot be verified, do not attempt to use the two-hand control safety
system until the defect or problem has been corrected. Attempts to use the guarded machine un-
der such conditions could result in serious bodily injury or death.
To perform the initial checkout, it is necessary to view the red Fault LED and the six green Status indicators. Proceed with caution around
open wiring.
If the SSI inputs are to be used, verify the checkout procedures for the external safety systems or other devices connected to the SSI
inputs as described by the appropriate manuals. Do not proceed until all checkout procedures are completed successfully and all prob-
lems have been corrected.
1. Verify that the two actuating devices are properly connected to the DUO-TOUCH SG Safety Module.
2. Apply power to the Safety Module and to the actuating devices, if applicable.
3. Verify that only the Power indicator is ON. The SSI indicator may be ON if the Safety Stop Interface is jumpered (i.e., not used) or if
the connected device is in a closed/GO condition. If any of the other Safety Module indicators are ON, disconnect the power to the
Safety Module and check all wiring. Do not continue this checkout procedure until the cause of the problem is corrected.
4. With the SSI input closed (i.e., SSI LED is ON), activate both hand controls simultaneously (within 0.5 seconds), and hold them
engaged. The Output indicators should come ON. Release both hand controls simultaneously. Output indicators should go OFF.
5. Again, activate the two hand controls simultaneously, and hold them engaged. The Output indicators should come ON. Release
one hand control, while holding the other engaged. One of the Input indicators should remain ON. Re-activate the hand control
which was just released. The Input indicator that was OFF should remain OFF. Release both hand controls. Input 1 and Input 2
indicators should then be OFF.
6. Activate only one hand control and hold it engaged. Input 1 (or Input 2) indicator should come ON. After more than 1/2 second,
activate the second hand control. Input 1 (Input 2) indicator should remain ON, while Input 2 (Input 1) indicator remains OFF.
7. Release both hand controls, and open the SSI inputs (if used). Verify that the SSI LED turns OFF. Activate both hand controls
simultaneously (within 0.5 seconds), and hold them engaged. Input 1 and Input 2 indicators should come ON, but the Output LED
must remain OFF.
8. Remove power from the Safety Module and disconnect the monitor contact feedback loop at terminals Y1 and/or Y2. Re-apply
power to the Safety Module. Close the SSI inputs, and activate both hand controls simultaneously. Input 1 and Input 2 indicator
LEDs should remain OFF.
If the DUO-TOUCH SG Safety Module passes all of these tests, reconnect power to the machine and the output wires at terminals 13/14,
23/24, 31/32, Y31, and Y32. Also reconnect 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.
