The pin assignments of the relays in the de-energized state are described in section Pin
assignments (Page 53).
The functions which can be assigned to the relays have the following meanings:

Limits
Upper and lower limits can be defined as events for energizing
relays. Select the desired relay(s) in the second and third lines of
this menu.
This function is specific to the component.
Measuring range
A relay for measuring range switchover can be assigned to each
measured component. This guarantees reliable assignment of
the analog output signal to the currently active range, especially
with autoranging (see section Parameter: Measuring ranges
(Page 127)).
