Product introduction

DEIF LMR-122D Channel relay module

Using the Reset Key with the LMR-122D Module The module is equipped with a reset key. The key is only required if the user name or password for administrator account is not known. If only the IP address set for the controller does not match the PADT (PC), the connection can be established with a routing entry (command Route add) on the PC. The key can be accessed through a small round hole located on the front plate. The key is engaged using a suitable pin made of insulating material to avoid short-circuits. The reset is only effective if the controller is rebooted (switched off and on) while the key is simultaneously engaged for at least 20 seconds. Engaging the key during operation has no effect.

NOTE Fieldbus communication may be disturbed! Prior to switching on the controller with the reset key engaged, unplug the controller's fieldbus connectors to ensure that the fieldbus communication among other stations is not disturbed. The fieldbus plugs may only be plugged in again when the controller is in the RUN or STOP state.
