MM-TA-12B Muting Module
Instruction Manual
3.3 Muting Module Configuration
The MM-TA-12B Muting Module should be configured before initial checkout and
use. Two banks of DIP switches are located under the access cover for the con-
figuration port. To access the DIP switches, unscrew the two captive, round-head
slot screws on either side of cover and carefully swing the cover open.
Because the MM-TA-12B has redundant microprocessors, two DIP switch banks
(Bank A and Bank B) must be set identically. Failure to set Bank A and Bank B
identically will result in a lockout condition. Power must be OFF when changing
DIP switch settings; changing settings while power is ON will cause a lockout
condition. The parameters to be manually configured are shown in Figure 3-2.

3.4 Connector Pin-outs and Functions
All electrical connections are made through either field-wireable or molded quick-
disconnect plugs. (See Specifications in Section 2 and Figure 3-3.)
Total Current Draw Calculation
Total current draw at the machine interface connector is the sum of the draw of
the Muting Module, the mute lamp, the AUX output and mute devices, and the
safeguarding device connected to the MSSI, if the power connections are used.
To calculate the total current draw, add the following:
I
TOTAL
= I
MM
+ I
AUX

+ I
MD

MM
= 400 mA (MM-TA-12B supply current) I

= X < 360 mA (mute lamp current)
I
MD
= X < 500 mA (M1-M4 supply current)
I
MSSI
= X < 2500 mA (MSSI supply current)
WARNING . . .
Proper Electrical
Hookup
• Electrical hookup must be made
by Qualified Personnel and must
comply with NEC (National
Electrical Code) and local stan-
dards.
• Make no connections to the
System other than those described
in Section 3 of this manual.
Doing
so could result in serious injury
or death.
NOTE: Switch numbers, e.g. “SW 1,” refer to
both switch banks A and B.
