MMD-TA-11B / MMD-TA-12B Muting Module
Instruction Manual
System Installation
3.6 Machine Interface – Initial Hookup and Checkout
Model MMD-TA-11B provides two normally open safety relay
output contacts (13−14 and 23−24) to hook up external MPCE1
and MPCE2 (see Figures 3-27 and 3-28).
Model MMD-TA-12B provides two PNP solid-state safety
outputs, OSSD1 and OSSD2 (Y5−Y6 and Y7−Y8) see Figures
3-24, 3-25, and 3-26.
For monitoring external devices (both models), normally closed
contacts of these devices must be hooked up to EDM #1
(Y1−Y2) and EDM #2 (Y3–Y4).
Before proceeding, ensure that power has been removed from
machine or ensure that power is not available to the machine
controls or actuators, and ensure that the machine control
(MPCEs) are not connected to or controlled by the OSSD or
relay safety outputs at this time. Permanent connections will be
made after Module initial checkout (see Section 3.7).
Verifying System Operation
The initial checkout procedure must be performed by a Qualified
Person (see Warning, page 12). It must be performed only
after configuring the Module and after properly installing and
configuring the safety systems connected to its MSSI and the
SSI inputs (per Section 3).
The initial checkout procedure is performed on two occasions:
• To ensure proper installation when the System is first installed,
and
• To ensure proper System function whenever any maintenance
or modification is performed on the System or on the machinery
being guarded by the System. (See Section 6.1 for a schedule
of required checkouts.)
For the initial checkout, the Muting Module and associated safety
systems must be checked without power being available to the
guarded machine. Final interface connections to the guarded
machine cannot take place until these systems have been
checked out.
Verify that:
• Power has been removed from (or is not available to) the
guarded machine, its controls or actuators;
• The machine control circuit is not connected to the OSSD
outputs at this time (permanent connections will be made
following this initial checkout), and that the OSSD leads are
isolated (i.e. not shorted together, not shorted to power or
ground);
• EDM has been configured for No Monitoring (SW4 = OFF or 2
CH) and EDM #1 (Y1−Y2) and EDM #2 (Y3−Y4) are jumpered;
• Other than EDM and Mute Enable, verify proper Module DIP
switch configuration for your application; and
• All input connections have been made per appropriate sections
for the Mute Input Devices (M1−M4), SSI, MSSI, Manual Reset
Switch, Mute Lamp, AUX Output, and Override Input.
This will allow the Muting Module and the associated safety
systems to be checked out, by themselves, before permanent
connections are made to the guarded machine.
3.6.1 Temporary Power and Initial Checkout
1. Connection of system DC power is at terminals A1
(+24V dc) and A2 (0V dc), see Section 3.4 and Figure 3-4.
All wiring must comply with NEC and local wiring codes.
2. Leaving power to the guarded machine OFF, power up the
Module and the safety systems connected to the MSSI and
the SSI inputs.
3. Perform system checkout procedures for the external
safety systems connected to the MSSI and SSI inputs as
described by the appropriate manuals. Do not proceed
further until all checkout procedures are completed
successfully and all problems have been corrected.
4. Verify that the external safety systems are providing a
Green/Go signal to the MSSI and SSI inputs (i.e., Banner
OSSD sourcing signal or a closed contact connected to
the “Signal” pin of each interface). Verify that the green
Channel indicators are ON.
NOTE: If the SSI is not to be used, terminals X5−X6 and X7−X8
must be jumpered (factory default). Do not short Channel
A to Channel B. See Section 3.5.6.
5. Auto Reset Configuration: Verify that the Green status
LED is ON, indicating that the OSSD outputs are ON, and
that a “—” appears on the Diagnostic Display. If not, or if
the Red status indicator begins to flash at any time, refer to
Section 5 for troubleshooting information.
Manual Reset Configuration: Verify that the Yellow status
LED is flashing to indicate that a reset is being requested,
and that a “—” appears on the Diagnostic Display. If not, or
if the Red status indicator begins to flash at any time, refer
to Section 5 for troubleshooting information.
Perform a manual reset by closing the Reset input for
at least 1/4 second, but not longer than 2 seconds, and
then reopening the contact. Verify that the Green status
indicator comes on steady. The Module OSSD outputs
should be ON at this time.
6. Cycle the MSSI and the SSI (if used) individually and
ensure that the Green status indicator goes OFF, and that
a reset is possible after the interface is closed.
If any of these checks fail, do not attempt to use the system
until the reason for the failure(s) is identified and corrected.
