Initial Checkout Procedure
To perform the initial checkout, it is necessary to view the Status indicators: Power, Fault,
K1 and K2. Proceed with caution around open wiring.
1) Verify that two actuating devices are properly connected to the DUO-TOUCH
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. If any 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) Activate one hand control and hold it engaged for 2 seconds, then release.
Repeat this step for other hand control. If the module locks out, do not continue
this checkout procedure until the cause of the problem is corrected.
5) Activate both hand controls simultaneously (within 0.3 seconds), and hold them
engaged. K1 and K2 indicators should come ON. Release both hand controls
simultaneously. K1 and K2 indicators should go OFF.
6) Again, activate the two hand controls simultaneously, and hold them engaged.
K1 and K2 indicators should come ON. Release one hand control while holding the
other engaged. One of the indicators should turn OFF. Re-activate the hand control
that was just released. The indicator that was OFF should remain OFF. Release both
hand controls. K1 and K2 indicators should then be OFF. Repeat for other hand
control.
7) Activate only one hand control and hold it engaged. K1 (or K2) indicator should
come ON. After more than
1
/
2
second, activate the second hand control. K1 (or K2)
indicator should remain ON, while K2 (or K1) indicator remains OFF. Repeat for
other hand control.
8) Remove power from the Safety Module and disconnect the monitor contact feed-
back loop at terminal X1 or X2. Re-apply power to the Safety Module. Activate
both hand controls simultaneously. K2 indicator LED should remain OFF, and the
Module should lock out.
If the DUO-TOUCH Safety Module passes all of these tests, reconnect the output wires
at terminals 13/14, 23/24, and 41/42. Also reconnect the monitor contact feedback
loop at terminals X1 and X2. Do not attempt to use the DUO-TOUCH Two-Hand
Control Safety Module until all of the previous tests are passed.
Periodic Checkout and Maintenance
Daily Checkout:
To be performed at every power-up, shift change, and machine setup
change. Daily checkout and checkouts after tooling and machine setup changes must
be performed by a Designated Person, appointed and identified in writing by the
employer.
1) Verify that all point-of-operation guards are in place and operating properly.
2) Verify that the two actuating devices must be simultaneously engaged to actuate
the machine.
3) For single-cycle machines: Verify that maintained engagement of the two
actuating devices results in only one machine cycle.
4) For part-revolution clutch machinery: Verify that release of either actuating device
results in the immediate arrest of the machine motion.
5) Verify that the distance from each actuating device to the closest hazard point is
not less than the calculated separation (safety) distance (see page 6).
CAUTION ...
Disconnect
Power Before Checkout
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, and 41/42.
!
WARNING ...
Do
Not Use System Until
Checkouts Are Verified
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.
