Service Information
This section describes corrective measures you can take if you encounter a problem
with an MS/TP PPM device. If you encounter a symptom or a problem not covered in
this manual, contact your Siemens Solution Partner, Authorized TALON Dealer
.
NOTE:
When removing power to a controller to perform maintenance or service, make sure
that the person in charge of the facility is aware of this and that appropriate steps are
taken to keep the building in control.
NOTE:
When troubleshooting, record the problem and what actions were performed
immediately before the problem occurred. Being able to describe the problem in detail
is important should you need assistance from your local Siemens Solution Partner,
Authorized TALON Dealer.
To view the status of the MS/TP PPM device and to call up reports for troubleshooting,
you can use an operator's terminal and the operator interface or a TALON View
workstation. For more information, see the following documentation:

Electrostatic Discharge
An electrostatic discharge (ESD) wrist strap is generally not required when installing or
servicing an MS/TP
PPM. However, if the device is installed in a very dry environment
where a high static discharge is likely, an ESD wrist strap is recommended.
Ordering Replacement Parts
If a MS/TP
PPM is not operating correctly, it should be replaced.
Reinstalling the Mounting Tabs
Do the following to reinstall a DIN mounting tab:
1. Place the wire spring clip into the pocket in the channel for the mounting tab.
2.
Make sure the mounting tab is face down. Working from the center (inside) of the
base, slide the mounting tab into the channel. (See the following figure.)
