Appendix

D Service menu

Shuttle

®

has a service menu that gives ac-

cess to settings that normally are not altered
by the user and therefore are protected by a
password.
The service menu includes:
- adjustment of the 4-20 mA output
- adjustment of the temperature compen-

sation

- functional control of keyboard and

display

- relay check
- changing of serial number and hard-

ware/software numbers

- self test function
Refer to '

Shuttle

®

Service Manual' for further

information of the functions in the service
menu.
