2.9 Troubleshooting
2.9.1 Introduction
This section is intended as an aid to fault finding, on an IMx-16Plus system. It is
designed for instrumentation engineers and others with sufficient knowledge of
electrical troubleshooting including safe working procedures, in electronic systems
powered by 24 to 48 V DC*. Be aware that invasive troubleshooting may cause
changes in alarm or channel status in the IMx-16Plus and any interconnected
systems.
*Note that the power supply to the system (for example, an IMx-Rail), may be
higher).
Whilst striving to provide information that is as accurate as possible, SKF cannot be
held responsible for any injury or damage to persons or material that occur in the
interpretation of or due to actions taken based on, information in this document.
2.9.2 Rescue Button
The IMx-16Plus has a rescue button that sets the device temporarily in maintenance
mode without a measurement configuration. This mode is used to support
troubleshooting and testing without the need to erase configuration and data.
The rescue button is designated ‘Sw’ and is accessible
via the hole in the top end
cap, refer
To enter maintenance mode, gently press and hold the rescue button as follows:
•
During IMx-16Plus start-up, press and hold for about 15 seconds
•
During IMx-16Plus normal operation, press and hold for about 2 seconds
The product warranty will be invalidated if the IMx-16Plus warranty seals
are broken, if that unit has been opened or if incorrect connections have been
made that expose any sub-system/circuit to voltages above their operational
rating.
Installation errors that require the involvement of SKF personnel to rectify, may
incur additional charges.
