The clock function has been reset to
default (2000-01-01) because of a power
failure.
1 or more of the preventive maintenance
events programmed in
parameter 23-10 Maintenance Item has
passed the time for the specified action in
parameter 23-11 Maintenance Action.
The frequency converter/system has
turned into sleep mode. See parameter
group 22-4* Sleep Mode.
A broken belt condition has been
detected. This function must be enabled
in parameter 22-60 Broken Belt Function.
The frequency converter is operating in
Fire mode. See parameter group 24-0* Fire
Mode.
To be used as signal for activating an
external electromechanical bypass,
switching the motor direct on line. See
24-1* Drive Bypass.
CAUTION
If enabling the drive bypass
function, the frequency converter is
no longer safety certified (for using
the Safe Torque Off in versions
where included).
All pumps running and at full speed.
One or more of the pumps controlled by the
cascade controller are running. The function
also depends on parameter 25-06 Number of
Pumps. If set to [0] No, Pump 1 refers to the
pump controlled by relay RELAY1 etc. If set to
[1] Yes, Pump 1 refers to the pump controlled
by the frequency converter only (without any
of the built-in relays involved), and Pump 2 to
the pump controlled by the relay RELAY1. See
Table 3.15.
