46 - EN
Switching direction max, direction of operation active: alarm if there is a
limit value overrange, e. g., sounder on
Switching direction max, direction of operation passive: switch off during
limit value overrange, e. g., pump, heating, ... off, for larger hysteresis Min-Max
operation (pump, heater, ... on/off)
Switching direction min, direction of operation active: alarm if there is a
limit value underrange, e. g., sounder is on.
Switching direction min, direction of operation passive: switch off during
limit value underrange, e. g., pump, heating, ... off, for larger hysteresis Min-Max
operation (pump, heater, ... off/on)
