Mode 1: Switch points for both relay outputs can be defined independent from each other in the range of 5 %... 95 % r. H. by turning control
knobs (R 1 for relay 1, R 2 for relay 2, see schematic diagram). When the respective switch point is exceeded, the corresponding relay switches
over (changeover contact W switches from position A to position B). When the preset switchpoint is undershot again by more than 3 % r. H.
(hysteresis), the respective switching output switches back to the initial position (changeover contact W switches from position B to position A).
Mode 2: Only control knob R1 is active (R 2 without function)! The switchpoint for the first relay is defined in the range of 5 %... 95 % r. H.
by turning control knob R 1 (see schematic diagram). The switch point for the second relay output is in mode 2 invariably defined as "switch
point 1 + 5 % r. H." A hysteresis of 3 % r. H. is predefined for each switching output also in mode 2.
