Operation

Operation monitoring
In most cases the side channel blower is controlled from the central control unit of the entire
system. Data associated with the design of the side channel blower and related to the
intended purpose (see specification) must be observed as a precondition for problem-free
functionality.
It is especially important to observe the points listed below during manual operation of the
side channel blower:
Note!
Make certain the following preconditions are met before initial commissioning
of the side channel blower:
1. The side channel blower is connected electrically with all protective devices
in accordance with requirements.
2. Rotating parts of the side channel blower must be provided with a contact
safety device. (In accordance with the accident prevention requirements
(UVV) the side channel blower may only be operated with a contact safety
device.)
3. The direction of motion has been checked.
Note!
1. Temperature of the conveying medium: Do not operate the side channel
blower at temperatures higher than those listed in the original specification.
2. Switching frequency:To avoid large temperature increases in the motor
and excessive load on the side channel blower, motor and bearings, one
switching-on process per minute must not be exceeded.
3. Minimum quantity: If the nature of the system includes the possibility of
running against the shut-off element closed on the pressure end, a
minimum flow for t -30 to +70°C of 15% of Qopt. and for over +70 to +110°C
of 25% of Qopt must be provided.
