Options

L80
CALOMAT CK145 without storage for motor temperature
prewarning
With this option, the motor prewarning temperature limit is
monitored using up to 6 PTC thermistors. If the prewarning
temperature is exceeded an alarm is output to the converter.
The fault is not stored on the CALOMAT and therefore does
not require acknowledgement.
L81
CALOMAT CK145 with storage for motor temperature trip
With this option, the motor trip temperature limit is monitored
using up to 6 PTC thermistors. If the trip temperature is reached
an alarm is output to the converter. The converter switches itself
off. The fault is stored on the CALOMAT and therefore has to be
acknowledged.
Note:
When CALOMAT devices are used for switch-off, a line contactor
must be installed on the input side (option
S01
or
S02
) for
compliance with ATEX 95 (Directive 94/9 EC).
L82
CALOMAT CK145 without storage for transformer
temperature prewarning
With this option, the transformer prewarning temperature limit
is monitored using up to 6 PTC thermistors. If the prewarning
temperature is exceeded an alarm is output to the converter.
The fault is not stored on the CALOMAT and therefore does
not require acknowledgement.
L83
CALOMAT CK145 with storage for transformer
temperature trip
With this option, the transformer trip temperature limit is
monitored using up to 6 PTC thermistors. If the trip temperature
is reached an alarm is output to the converter. The converter
switches itself off. The fault is stored on the CALOMAT and there-
fore has to be acknowledged.
Note:
When CALOMAT devices are used for switch-off, a line contactor
must be installed on the input side (option
S01
or
S02
) for
compliance with ATEX 95 (Directive 94/9 EC).
Apart from disconnecting the converter, it is also recommended
that the already existing tripping device on site is disconnected
that is connected upstream of the transformer, such as the
medium-voltage switch.
Y80
CALOMAT CK145 for other PTC thermistor temperature
monitoring functions
With this option, a temperature limit is monitored using up to
6 PTC thermistors. If the temperature limit is reached an alarm
is output to the converter. Please specify whether the fault
should be stored on the CALOMAT and therefore has to be
acknowledged or not.
L87
Insulation monitoring
L87
Integrated insulation monitoring system for operation on the
secondary side of unit transformer in an IT system
L87
Insulation monitoring
An insulation monitor must be used if the converter is connected
to a three-winding transformer. The insulation monitor IRDH 275
from Bender monitors the entire galvanically coupled circuit for
insulation faults.
This option is included as standard fully wired up in the cabinet
for insulation monitoring with 12-pulse and higher-pulse convert-
ers on a unit transformer that is not
grounded on the secondary
side.
Function:
The insulation resistance of all galvanically coupled components
(converter transformer secondary winding, cables, converter,
motor) is monitored by means of a measured signal that is
modulated onto the line supply. If the insulation resistance is
undershot, an alarm or trip message is output.
Notice:
Only ONE insulation monitoring device at a time is permitted in
the entire galvanically coupled network. False tripping occurs if
2 devices are used. This option is therefore only
suitable for
converter operation with one converter.
