When the Panel is turned on and the Panel On LED and Control Source are the only LEDs that are
lit. This is because the Control Panel has No Data for any of the phases. The likeliest cause in this
case is the RCU has just been powered up and is searching for Fusesavers and has not found a
correctly configured Fusesaver line.
9.7.7 Panel does not turn on
There are a number of valid reasons for a Fusesaver Control Panel not turning on:
The RCU is configured with the Fusesaver Control Panel disabled.
The RCU firmware is an old version and cannot drive the Fusesaver Control Panel.
The Fusesaver Control Panel Connector is not plugged into the RCU. It is acceptable to plug
the panel into a powered up RCU (hot connection). On re-connection it may take up to 30
seconds for the RCU to detect the Fusesaver Control Panel.
The RCU Power is off.
9.7.8 Panel LEDs are all flashing On / Off
The Fusesaver Control Panel type is unknown to the RCU. The RCU requires a panel map update.
Siemens Service Centre can assist with providing the correct panel mapping.
9.7.9 Panel LEDs turn on one-by-one across the panel
The Fusesaver Control Panel firmware version is not compatible with the firmware in the RCU.
Siemens Service Centre can assist with providing the latest panel firmware.
9.8 Switchgear Replacement and reconfiguration
If a Fusesaver is replaced or any change made to the Fusesaver line name then the RCU should be
powered down and up again so that it will search again and find the changed installation.
Similarly, if a CMR is replaced or its configuration is changed, then the RCU should have its
configuration updated where appropriate, and be power cycled.
In particular, the RCU must be turned OFF (the Mains, Solar and Battery Switches in the “O” position)
if the phase configured of CMR devices is being changed. Once all CMR devices have had their
phase configuration updated, the RCU can be turned back on, and its configuration updated to match
that of the CMRs. Refer to [3] for further information.
9.9 Manufacturer's product liability
The manufacturer's product liability shall be excluded if at least one of the following criteria applies:
Original Siemens spare parts are not used.
Fitters carrying out replacements have not been trained and certified by Siemens.
Parts have been incorrectly fitted or adjusted.
Settings are not made in accordance with Siemens specifications.
After installation and setting, no final test is performed by a qualified person including
documentation of the test results.
To keep documentation complete, it is important that measurement results are submitted to the local
competent Siemens agency.
9.10 Disposal
The materials of the Remote Control Unit should be recycled. Disposal of the Remote Control Unit
with minimum environmental impact is possible on the basis of existing legal regulations.
