Muting Functions and Safety Stop Interface
Mute Enable (ME) Input
The Mute Enable input is a non-safety-rated input. When the input is closed, a mute
cycle is allowed to begin; opening this input while the Module is muted will have no
effect. If the application does not require the Mute Enable function, then the X1/X2
input must be jumpered.
Typical uses for Mute Enable include:
• To allow the machine control logic to create a “window” for muting to begin,
• To inhibit muting from occurring, or
• To reduce the chance of unauthorized or unintended defeat of the safety system.
Mute Lamp (ML) Output and Configuration
Most applications require that a lamp (or other means) be used to indicate when the
safeguard is muted; the AT-..M-11KM provides for this at terminals Z3 and Z4 (see
WARNING at right). This indication is selectable between a monitored or a non-
monitored output signal (NPN sinking). The monitored output will prevent the initiation
of a mute if an indicator failure is detected (current draw falls below 10 mA or goes
above 360 mA). If the muting function is to be used in a country governed by EN
regulation (requiring the CE mark), Lamp Monitoring must be selected and the lamp
used must meet applicable requirements (see Figure 5).
In addition to fulfilling the above requirement, the Mute Lamp output also can be used
to prompt the operator when the hand controls may be released. This reduces the
chance of premature release of the two-hand control actuators.
Backdoor Timer
The Backdoor Timer allows the user to select a maximum period of time when muting
is allowed to occur (see Figure 5). The Backdoor Timer helps to hinder the intentional
defeat of the muting devices and it is also useful in detecting common mode failures
that could affect the mute devices.
The timer begins when the second muting device makes the simultaneity requirement
(actuated within 3 seconds of the first muting device being actuated), and will allow a
mute to continue for the predetermined time. After the timer expires, the mute cycle will
end – no matter what the signal from the mute devices indicates – and the safety
outputs will open (even if the two-hand control switches are actuated).
Safety Stop Interface (SSI)
The SSI provides for easy integration of safeguards, E-stop buttons, process control,
etc. This input is always active: opening either channel will cause the AT-..M-11KM to
issue a stop command. The channels operate concurrently (both must open and
re-close, but not necessarily within a certain time frame). If the SSI is not to be used,
terminal X3 must be jumpered to X4, and terminal X5 must be jumpered to X6.
If the SSI is to be used, the connected device(s) must have electrically isolated,
redundant hard contacts (voltage-free). See Figure 8d for hookup information and page
15 for contact specifications.
A variety of safety systems can be interfaced with the SSI. Each safety application has
unique application requirements, and the user is responsible for ensuring proper
installation, use, and compliance with all relevant standards and regulations. If there are
any questions, contact the Banner Factory Applications Group at the phone number on
the back page to discuss your intended use.

Indication that the safety device is muted
must be provided and must be readily
observable. Failure of this indication
should be detectable and prevent the next
mute, or the operation of the indicator
should be verified at suitable intervals.
Lamp monitoring must be selected if the
system is to be used in a country governed
by EN regulation (i.e., requiring CE mark).
