If no Latch Reset functions are used, verify that the Safety Output turns On
Important: Always test the safeguarding devices according to the recommendations of the device
manufacture.
In the sequence of steps below, if a particular function or device is not part of the application, skip that step
and proceed to the next check list item or to the final commissioning step.
Two-Hand Control Function without Muting
1. Make sure the Two-Hand Control actuators are in the Stop state.
2. Make sure that all other inputs associated with Two-Hand Control function are in the Run state and activate the
Two-Hand Control actuators to turn the associated Safety Output On.
3. Verify that the associated Safety Output remains Off unless both actuators are activated within 0.5 seconds of each
other.
4. Verify that Safety Output turns Off and remains Off when any single hand is removed and replaced (while
maintaining the other actuator in the Run state).
5. Verify that switching a safety input (non Two-Hand Control actuator) to the Stop state causes the associated Safety
Output to turn Off or stay Off.
6. If more than one set of Two-Hand Control actuators is used then the additional actuators need to be activated
before the Safety Output turns On. Verify that the Safety Output turns Off and remains Off when any single hand is
removed and replaced (while maintaining the other actuators in the Run state).
Two-Hand Control Function with Muting
1. Follow the verification steps in Two-Hand Control function above.
2. Activate the Two-Hand Control actuators then activate the MP1 sensors.
3. With the MSP1 sensors active, remove your hands from the Two-Hand Control and verify that the Safety Output
stays On
4. Verify that the Safety Output turns Off when either:
•
MSP1 sensors are switched to the stop state
•
Mute time limit expires
5. For multiple Two-Hand Control actuators with at least one set of non-mutable actuators: verify that while in an
active mute cycle, removing one or both hands from each non-muted actuators causes the Safety Outputs to turn
Off.
Bidirectional (Two Way) Muting Function (Also valid for Zone Control Mute Functions)
1. With the muted safeguard in the Run state, activating the Mute Enable input (if used) and then activate each mute
sensor, in sequential order, within 3 seconds.
2. Generate a stop command from the muted safeguarding device:
a. Verify that the associated Safety Outputs remain On.
b. If a mute time limit has been configured, verify that the associated Safety Outputs turn Off when the mute
timer expires.
c. Repeat above steps for each Muting Sensor Pair.
d. Verify proper operation with each muted safeguarding device.
e. Generate a stop command from any non-muted safeguarding devices one at a time while in the mute cycle
and verify that the associated Safety Outputs turn Off.
f. Verify the mute process in the opposite direction repeating the process above, activating the mute sensors
in the reverse order
NOTE: In the diagram above, when a mutable safeguarding device uses the latch reset function and
changes to the Stop state during the mute cycle, a latch reset operation is not needed to reset the
safeguard. If the safeguard is in the Stop before the mute cycle starts then the associated Safety
Output stays off until the safeguard is in the Run state and a manual reset is performed.
Unidirectional (One Way) Muting Function
1. With the mute sensors not activated, muted safeguarding devices in the Run state and Safety Outputs On:
a. Activate Muting Sensor Pair 1.
