Checking For Circuit Faults - SKF Multilog On-Line System IMx-M User Manual

Protection
IMx-M Manager
Important - Do not arm slot while the configuration file is still downloading.
This can result in an invalid configuration, forcing the system to indicate a circuit
fault condition.
Important - Rack/slot must be set in slot disarm mode before the protection
configuration sending procedure takes place. Be sure to read "Disarm" chapter
thoroughly and understand it.
Important - Do not turn off the power during the protection configuration
update process.
Important - If the configuration of a slot is to be updated and the slot is
disarmed through a digital input, it is strongly ADVISED to make sure that the
same digital input is configured as slot disarm input. Failing to do so could lead to
unintentionally arming of the slot when the slot restarts and the new configuration
is activated.
Important - For detail information when shared relays are used, also see
chapter
in Relays chapter.

Checking for Circuit Faults

After updating the slot configuration and before arming the slot, both the PRM and the
RLM shall be checked for circuit fault conditions.
There are two ways to do this: either from the lower "Command" text box, by entering
the command "cf", or from the main menu selecting "PRM Serial Commands" and
"Send CF Command".
Either method will instruct the slot to query all channels and relay configurations for
circuit faults. If everything is OK, then all returned result values will be zero.
