Instruction Manual

Operating Instructions

WARNING . . .

Verify Proper Operation

The Muting Module and safety systems can do
the job for which it was designed only if it and

the machine it guards are operating properly, both separately
and together. It is the user’s responsibility to verify proper
operation, on a regular basis, as instructed in Section 6.
If the Muting Module, safety systems, and the guarded
machine do not perform exactly as outlined in the
checkout procedures, the cause of the problem must be
found and corrected before the system is put back into
service.
Failure to correct such problems can result in serious
bodily injury or death.

WARNING . . .

Power Failures

Power failures or other Module lockout
conditions should always be investigated

immediately by a Qualified Person. A lockout is a definite
indication of a problem and should be investigated at
once. Attempts to continue to operate machinery by
bypassing the Module are dangerous and could result in
serious bodily injury or death.

4.1 Security Protocol

The Module must be mounted inside a lockable enclosure or

cabinet rated IP54 or better, both to protect the Module from

environmental conditions and in order to prevent access by

unauthorized personnel, if required by applicable standards.
The key (or combination) to the enclosure should be kept in

the possession of a Qualified Person and only they should

have access to the configuration switches. A Qualified Person

is defined as an individual who, by possession of a recognized

degree or certificate of professional training, or who, by

extensive knowledge, training, and experience, has successfully

demonstrated the ability to solve problems relating to the subject

matter and work.

4.2 Periodic Checkout Requirements

In addition to the checkouts that are performed by a Qualified

Person or persons at the time that the Module is installed and

put into service, the functioning of the safeguarding and the

machine must be verified on a regular periodic basis to ensure

proper operation. This is absolutely vital and necessary. Failure

to ensure proper operation can lead to serious injury or death.
See Section 6 for checkout schedules and procedures.

4.3 Normal Operation

During normal operation, the Module’s three status indicators

(red, green and yellow) are as shown in Figure 4-1. In addition,

green and yellow indicators adjacent to each of the Module’s

inputs/interfaces come ON to verify an active state of that circuit.
During normal operation, the Diagnostic Display will read “—”

(solid or, if during the mute cycle, flashing). 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). If the Red status indicator

begins to flash, the number that appears in the Display signifies

an error; see Section 5.2 for more information.
See Section 3.5.1 for information on the reset routine.
