Section 6 Diagnostics and Maintenance
6.1 Maintenance instructions
GUID-BFAA5AF5-0677-4F3A-AE34-2CD95247B4CF v1
SAM600 modules are self-supervising. If a SAM600 module experiences a problem it will store
the information in the event log. It is advisable to read the contents of the SAM600 module’s
event log during regular intervals and to back-up the information in case a later analysis should
be necessary.
In case of a serious malfunction, the SAM600 module tries to clear the problem by restarting
and re-initializing itself several times until it waits in startup mode. Information about clearing
attempts is also logged as system events. If the situation cannot be cleared the SAM600
module will block its operation and indicate the error by steady light on the HMI (see Section
7.2.3). The cause of the error is described in a SAM600 event log.
Servicing of SAM600 module
In case of SAM600 module maintenance, ensure that safety instructions and cabling
verification according to
Section 4.5 are followed.
SAM600 modules in operation can heat up to the ambient temperature in the
mounted kiosk. Ensure that the surface of SAM600 module has cooled down to
room temperatures.
Before servicing a SAM600 module, visually inspect that no wires connecting to
SAM600 modules have loosened.
Replacing a SAM600 module
In case a SAM600 module is damaged it must be replaced. Follow the steps for dismounting
the SAM600 module as described in
Section 4.6.
Contact an ABB representative for replacement or repair handling instructions.
Before dismounting a SAM600 module make sure to de-energize all equipment
connected to the SAM600 module’s analog connectors. Make sure that the
SAM600 module’s power supply and digital input connection are removed and
the module is electrically isolated.
The SAM600 replacement module must be mounted according to the installation instructions
in
Section 4.6. PCM600 can be used to restore the configuration from a backup. After
restoring, the SAM600 replacement module will integrate seamlessly into the SAM600 system.
