Handset Setup Procedures

MTS Model 494.05 Handset

15

Allowing exclusive control of the handset at any access level allows tuning
and calibration adjustments to be made while the handset has exclusive
control. This may result in unexpected system response.

Unexpected system response may cause injury and damage equipment.

Ensure that all personnel are properly trained and are aware of the state of the
“Allow exclusive control at any access level” control when using the equipment.

Using this control to

facilitate tuning and

calibration

This control is provided to facilitate tuning and calibration. While performing
these operations, it is convenient to have access to the Station Manager
application tuning and calibration controls at the PC interface while the Handset
has exclusive control. This allows you to quickly iterate between control
adjustments and position adjustments of the actuator, specimen, and fixturing.

When the “Allow exclusive control at any level” control is enabled, tuning
and calibration adjustments may be made at the PC interface while the
handset has exclusive control. This may result in unexpected system
response.

Unexpected system response may cause injury and damage equipment.

This control is disabled by default. MTS recommends that you do not enable this
control for normal use, and that you disable (click to clear the checkbox) when
tuning and calibration are complete.

Hazard considerations

when enabling this

control

When this control is enabled, an operator at the PC interface may make changes
to the tuning and calibration controls while another operator is using the handset.
This means the PC operator can make adjustments that affect the response rate of
the actuator while the Handset operator is using the handset to position the
actuator. This is potentially unsafe.

For example, if the PC operator makes a large adjustment to the P Gain control
while the handset operator is positioning the actuator, the actuator may instantly
and forcefully clamp shut.

Requirements to enable

and disable this control

To enable this control, you must attain the Configuration access level.

To disable this control, you may be at any access level.
