These error messages indicate a possible error with the loop or the connections to the loop:
LOOP A OPEN LOOP The driver measured a very high loop impedance on output A .
WILL CLIP: Please check the loop and the connections to the driver . This is a
warning and after 5 seconds the driver will proceed with the start-
up diagnostics .
LOOP A R < 200mR The driver measured < 200mR for the loop A impedance . This is
FIX AND RESTART: too low for the driver and must be fixed before the driver will finish
the start-up diagnostics. Switch off, fix the fault and switch on
again .
LOOP B OPEN LOOP As above for loop B .
WILL CLIP:
LOOP B R < 200mR
As above for loop B .
FIX AND RESTART:
LOOP A > 10R LOOP The loop is not open circuit but has a resistance of > 10R . This is
COULD CLIP: too high and the driver will clip on output peaks . This is a warning
and the driver will continue after 5 seconds .
LOOP B > 10R LOOP As above for loop B .
COULD CLIP:
CHANNEL A OPEN CIRCUIT: This message is displayed if the loop is disconnected whilst the
driver is operating (e.g. if a carpet fitter cuts the loop). The
message is displayed on the front panel for 5 seconds and on the
web interface .
CHANNEL B OPEN CIRCUIT: As above for loop B .
These are information messages and do not indicate an error
:
DIAGNOSTICS This message is displayed on the front panel whilst the start-up
IN PROGRESS: tests are being performed .
DRIVER IS NOW LOCKED: You have completed the lock sequence and the front panel is now
locked .
DRIVER IS **LOCKED**: This is displayed on the front panel if a front panel key is touched
whilst the driver is locked . Unlock the driver to access the front
panel .
DRIVER IS UNLOCKED: You have completed the unlock sequence and the front panel is
now unlocked .
CHAN B CURRENT The combination of the output B offset setting and the combined
LIMIT EXCEEDED: current setting mean that the level of out B current exceeds 0 .
For example this can be done by setting offset B to +5dB and then
trying to set the current to -4dB (which would make channel B
c1dB). The driver will ignore the command that causes the
error condition .
New IP Address A new Ethernet address has been assigned to the driver . This can
XXX.XXX.XXX.XXX: occur when an Ethernet cable is plugged into the driver or the
DHCP system re-assigns a new IP address .
SLAVE MODE ENABLED:
This message is seen when a plug is inserted into the slave in
socket on the driver .
