Your MK tensionmeter can be factory-equipped with MIN/MAX tension-detecting
contacts which allow you to monitor the tolerance limits for the measured tension.
These factory-installed contacts are free from potential. Instead of the lamps shown in
the illustration it is of course also possible to connect other equipment, such as bell,
horn, relay, etc.
The contact load specified in fig. 3.4 of max. 24 V / 2 W must not be exceeded.
The setting of the desired tolerance range has to be tuned to the local conditions by
experimenting.
To set the MINIMUM tolerance limit
:
- Loosen the LOCKNUT on the MIN-SETSCREW.
Turn the SETSCREW clockwise
=
to decrase the MINIMUM-tolerance
Turn the SETSCREW counterclockwise
=
to incrase the MINIMUM-tolerance
- Fasten the LOCKNUT on the MIN-SETSCREW
To set the MAXIMUM tolerance limit
:
- Loosen the LOCKNUT on the MAX-SETSCREW.
Turn the SETSCREW clockwise
=
to decrase the MAXMUM-tolerance
Turn the SETSCREW counterclockwise
=
to incrase the MAXMUM-tolerance
- Fasten the LOCKNUT on the MAX-SETSCREW
