of injury
Please observe, in particular,
Chapter 5 (Safety) when working on the non
-
contacting thermal switch unit!
A commissioning not performed properly could cause injury to persons, or
harm to property and the environment!
Experts only ar
e allowed to perform commissioning, in particular, first starting
of the turbo coupling!
Secure the machine against unintentional switching on!
•
Check the wiring according to wiring diagram ( Chapter 6.4).
•
Please pay special attention to the proper wiring of the supply voltage!
•
Apply supply voltage to the evaluator, first without starting the turbo coupling. As
long as the start-up bypass is active, the output relay remains energized and the
front LED lights up.
•
At the end of the start-up bypass time, the output relay is de-energized and the
front LED extinguishes.
•
If necessary, set the start-up bypass time according to Chapter 7.3.
•
In case of external triggering, remove the bridge that was fixed at the factory
between the terminals for the start-up bypass on the evaluator.
•
Start the BTS-Ex with turbo coupling in a normal way. After the start-up bypass
time, the speed of the turbo coupling with switching element must have clearly
exceeded the set cutoff frequency. If there is no excess temperature, the output
relay remains energized and the front LED lights.
•
Switch off the drive with the turbo coupling, leave the BTS-Ex in the mode ready
for operation. If the speed of the turbo coupling with switching element falls below
the set cutoff frequency, the output relay is de-energized and the front LED
extinguishes.
•
Normal operation can start now. In case of malfunctions, Chapter 11.
