Replacing devices
888546187
A critical error in one of the samosPRO modules will affect the entire network. Therefore, de-
vices that have critical errors must be quickly repaired or replaced. We recommend keeping
replacement samosPRO module devices at the ready so that you can reestablish network ope-
ration as quickly as possible.
Safety measures when replacing devices
888547723
Follow the following safety measures when replacing samosPRO modules:
• Do not attempt to dismantle or repair the samosPRO modules. This not only will void war-
ranty claims against Wieland Electric, but it is also dangerous, because in this case it is not
possible to test the original safety functions.
• Place the device back into a condition in which the safety will be ensured.
• Only carry out replacement when the power supply is switched off in order to prevent
electric shock or unexpected behavior from the device.
• In order to enable further use of the system configuration, check the following:
– Is the new module of the same type (same material number) and is the new module
error-free after replacement?
– Was the new module inserted into the same position at which the replaced module
was?
– Were all plug connections connected back at the correct location?
• If not, you will need to completely reconfigure the new system and commission it inclu-
ding all of the necessary tests (see Commissioning [ch. 9, p. 70] ).
NOTICE • After replacement, make sure that no errors are occurring with the new samosPRO mo-
dules.
• Be sure to carry out a function test before commissioning a replacement module.
• When you send in samosPRO modules for repair, generate a report of your project in sa-
mosPLAN 6 and carry out diagnostics; enclose a detailed description of the problem with
the device, and send the samosPRO modules along with all available information to Wie-
land Electric.
