Ziehl motor
The smaller one-phase motors (motor size B) have a Modbus RTU bus interface. With an additional Modbus
card, the bus is available for larger motors as well. The need for the bus has to be determined when ordering
the fan, so that it can be included in the delivery.
Motor size B also includes connection A1 that switches to the GND potential inside the device, according to a
certain sequence. Refer to the device manufacturer’s instructions for different sequences and their explana -
tions.
A running indication is received from the motor via the potential-free contact K1, the maximum load of which at
alternating voltage is 250 V / 2 A. The relay is activated when the rotating speed of the motor exceeds 150 rpm.
The current limits are 10 mA for the 10 V output and 70 mA for the 24 V output. Do not connect output con
-
nections of various devices with each other.
12.7. Maintenance, spare parts and warranty
WARNING
The operation of components relating to safety must be checked regularly, and any faults
must be rectified immediately. Maintenance work relating to the electrical devices must
only be performed by qualified and authorized service personnel. The components must
be de-energized and the impeller stopped for the duration of the maintenance. The
equipment must be measured to ensure that it is de-energized.
Fans should be checked every six months. All faults must be rectified immediately. If the faults can cause an
immediate danger, the equipment must not be used before the fault is rectified.
Only use spare parts that have been approved by the manufacturer of the motor, fan and frequency converter
in question. For other Future unit series’ electrical installations (service switches, lights, cables, etc.) you can
use spare part components with an identical electrical rating and operation.
Do not make arbitrary or structural alterations to the fans. Such alterations will void the equipment manufac
-
turer’s warranty. An impeller replacement must be performed by personnel authorized by the manufacturer.
After maintenance and commissioning work, check the equipment for reliable and correct operation.
Refer to the component manufacturers’ websites for detailed component-specific maintenance and operating
instructions. The instructions prepared by the component manufacturer have always priority.
Koja Ltd and component manufacturers do not compensate for damage arising from installation, use, transport
or storing of devices without following the instructions.
