MMD-TA-11B / MMD-TA-12B Muting Module

Instruction Manual

System Installation

3.7.1 Mute Enable Hookup

The Module provides a Mute Enable input (“ME,” X13−X14) for

the connection of a potential free contact (see Section 1.12).

Mute Enable gives the user the ability to “frame” or create a

“window of opportunity” when a mute can occur. When

configured, the Mute Enable input is a contact that must be

closed before the safeguard can be muted. After the safeguard

is muted, opening of the Mute Enable input has no effect, but it

must be re-closed before the safeguard can be muted again.
To hook up a device (sensor or PLC output) with a solid state

output, see optional hookup in Figure 3-23.
If Mute Enable is not to be used, leave the factory-installed

jumper between X13–X14.

3.7.2 External Device Monitoring (EDM) Hookup

The Module provides connection terminals for the External

Device Monitoring input (EDM #1—Y1−Y2 and EDM #2—

Y3−Y4). External Device Monitoring must be wired in one of

three configurations:
• One-Channel Monitoring — SW4 Banks A and B = ON or 1 CH

(see Figures 3-26 and 3-28). NOTE: EDM #2 input must be left

open.

• Two-Channel Monitoring — SW4 Banks A and B = OFF or 2 CH

(see Figures 3-24, 3-25, and 3-27).

• No Monitoring — SW4 Banks A and B = OFF or 2 CH

NOTE: Terminal Y1 of EDM #1 must be jumpered to Y3 of

EDM #2.

After the initial checkout has been successfully completed, the

EDM configuration that disabled the monitoring function must

be properly reconfigured. The External Device Monitoring inputs

then must be properly connected to the closed monitoring

contacts of the MPCEs (see Section 1.10). Refer to the NOTICE

Regarding MPCE Monitoring Hookup, below, and Figures 3-24,

3-25, 3-26, 3-27, and 3-28.

EDM Configuration

If the application does not require this function,
the terminal Y1 of EDM #1 must be jumpered to

Y3 of EDM #2 (see Section 3.7.2). It is the user’s responsibility
to ensure that this does not create a hazardous situation.

NOTICE Regarding External Device Monitoring Hookup

It is strongly recommended that one normally closed,
forced-guided, monitoring contact of each MPCE or external
device be wired in order to monitor the state of the MPCEs
(as shown in Figures 3-24 to 3-28). If this is done, proper
operation of the MPCEs will be verified. MPCE monitoring
contacts must be used in order to maintain control reliability.
