Control Functions
There are two methods that can be used to scroll through screens or make changes within programming
modes. If in a safe area with the front cover removed, the 4 push buttons showing through the front
face plate can be used with the button function as shown on the face plate.
If programming or screen changes are to be made while the RT-30EX is in the hazardous area, do not
remove cover to use the push buttons. Keep cover on and use the magnetic wand. Only use push
buttons in a non-hazardous area.
Alternately, with the cover closed it is possible to make changes using the magnetic wand attached to
the outside of the unit. The push button functions are duplicated with internal Hall switches which
activate when the magnetic wand is held in the 3, 6, 9 or 12 o’clock positions as shown in Figure 19 and
Figure 20. The face plate is marked at each position with the corresponding function.
