VC II 230/400-3...15 7
If during the maximum braking time (10s in the case of standard devices) no motor standstill is
detected, the fault signaling contact on the terminals 13, 14 opens and the red „fault“-LED lights
up. When the motor is restarted, this fault indication will be reset. If this fault occurs 3 times in
succession during an operation phase, the VersiComb II goes into fault condition. It is no longer
possible to switch the drive on.
Exceeding of the max. heat sink temperature, a defective or charred ON-key, trigger faults or
synchronization errors as well as reaching of the max. motor temperature (if a motor PTC or a
thermal contact (bimetal) is connected to 7, 8) also cause the VersiComb II to go into this fault
condition which can only be left by remedying the fault and carrying out a mains reset.
By switching the device on, the operational status contact on the terminals 9, 10 is closed, and it
is open from the beginning of the soft start until the end of braking by the
standard devices
.
By the
VC II 400-5,5 ... 15 SO1
devices the operational status contact on the terminals 9,10 is
closed from the end of the soft start until the beginning of the braking.
By the
VC II 400-5,5 ... 15 SO3, SO9
devices the operational status contact on the terminals
9,10 is closed from the beginnung of the soft start until the end of the braking.
Warning
To protect the motor and the braking electronics, it is necessary, when
putting the device into operation, to check the braking current with a true
r.m.s. measuring instrument. Simple multimeters and clamp-on probes
produce wrong measurements, since they are only suitable für pure sine-
wave forms and not for phase control.
If, due to the fact that heavy rotating masses are to be slowed down, it is not possible to bring the
motor to a standstill with the permissible maximum braking current (rated device current), a
device of a higher performance category has to be used.
