MMD-TA-11B / MMD-TA-12B Muting Module
Instruction Manual
System Installation
If the Muting function is not used, proceed to Section 3.7.
During the initial checkout procedure of the Muting feature, if
possible, verify that the power has been removed or is otherwise
not available to the machine actuators responsible for hazardous
motion. At all times ensure that personnel are not exposed to
any hazard.
7. Mute the System by blocking (or activating) both mute
devices (typically M1 and M2) simultaneously (within 3
seconds).
8. If used, verify that the Mute indicator comes ON. If not,
check the indicator and its wiring, and check the Diagnostic
Display for error codes.
9. Generate a stop command from the safeguarding device
connected to the MSSI (e.g., interrupt the defined area of
a safety light screen). Verify that MSSI Channel A and B
indicators go OFF, but the Green status indicator remains
ON.
NOTE: If the 30- or 60-second Backdoor Timer feature is
selected, the Diagnostic Display will begin to count down
in seconds. If the 30-minute Backdoor Timer feature is
selected, the timer countdown is in minutes. A flashing
dash will appear on the display if the Backdoor Timer is
OFF (infinite).
10. Clear the Stop command (before the Backdoor Timer
expires) and verify that the MSSI Channel A and B
indicators come ON. Clear (deactivate) the mute devices
before the Backdoor Timer expires and verify the Mute
indicator goes OFF. The Green status indicator should
remain ON.
11. Verify that it is not possible for a single individual to
initiate a mute condition by triggering the mute devices
(for example, by blocking both photoelectric beams or
actuating both switches) and being able to pass through the
safeguard without being detected and without issuing a stop
command to the machine. Do not expose any individual to
hazard while attempting to mute the system.
12. Verify that it is not possible for personnel to pass in front of,
behind, or next to the muted object without being detected
and without issuing a stop command to the machine.
13. If one-way (directional) muting has been selected, verify
that the system can not be muted by blocking (or activating)
M3−M4 before M1−M2. Do not expose any individual to
hazard while attempting to mute the system.
If all checks have been verified, proceed to Section 3.7. If
any of these checks fail, do not attempt to use the system
until the reason for the failure(s) is identified and corrected.
3.7 Permanent Hookup to the Guarded Machine
OSSD and EDM Connections and Electrical Interface
Supply power, the external reset switch, and other inputs (as
required by each application) should be previously connected by
this point. The final connections to be made are:
• Mute enable,
• EDM hookup,
• OSSD outputs,
• FSD interfacing, and
• MPCE connections.
WARNING . . . Shock Hazard
Always disconnect power from the Safety
System and the guarded machine before
making any connections or replacing any component.
Use extreme caution to avoid electrical shock at all times.
Serious bodily injury or death could result.
WARNING . . . Proper Wiring
The generalized wiring configuration shown
in Figures 3-24, 3-25, 3-26, 3-27 and 3-28
are provided only to illustrate the importance of proper
installation. The proper wiring of the Safety system to any
particular machine is the sole responsibility of the installer
and end user.
